How do I adjust the folding cylinder?
To adjust the folding cylinder, lift the folding frames with appropriate means, remove the bolt and keep adjusting the bolt eye on the piston rod, until the frame is parallel to the centre frame, and insert the bolt so that the lug is able to accommodate the safety catch function.
What should I do when maneuvering the machine?
When manoeuvring the machine, pay attention to the surroundings. No persons (children) are to remain in the manoeuvring area of the machine.
How should I park the machine?
To park the machine, park the machine on level and solid ground, switch off the tractor, secure the machine against rolling away and unhitch it, disconnect hydraulic and electrical connections and hook into bracket devices, disconnect brake lines (optional), place the parking support under the machine, unhitch the machine, turn the coulter pressure control back in order to relieve the rubbers so that they will not lose their tensioning force, empty the seed hopper, clean the metering unit, close the hopper cover, store the terminal in a dry room, and equipment with pneumatic brake; drain air reservoir and seal hose couplings during longer downtime periods.
What should I do if solid fertilizer was used?
Thoroughly clean hopper, metering unit and machine if solid fertiliser was used. Fertiliser is aggressive and speeds up the corrosion process. It especially attacks galvanised components like bolts.
What should I regularly check for?
Fan impeller and protective grid have to be regularly checked for deposits and cleaned.
What should I check on all coulters when starting sowing?
Fan setting, seed transportation and seed placement must be checked on all coulters when starting sowing, and also at regular intervals when working on large areas.
What should I ensure regarding the return line connected to the tractor?
The return line connected to the tractor must be a freeflow return!
What should I clean at regular intervals?
Clean the air intake grid at regular intervals to prevent a restriction in air flow and resulting blockage.
What should I clean to prevent unbalance and damage?
Clean any dirt or deposits from the fan blades to prevent unbalance and damage to impeller and bearing.
What should I do with the clamping taper on the fan shaft?
Retighten the clamping taper on the fan shaft.
What should be slightly increased with higher drilling speeds?
With higher drilling speeds the rotary speeds must be slightly increased.
What should be checked when starting sowing?
Fan setting, seed transportation and seed placement must be checked on all coulters when starting sowing, and also at regular intervals when working on large areas.
How do I adjust the fan speed?
With the engine running switch on the PTO-shaft and run the tractor engine with the speed used for drilling, and set the desired fan speed by the setscrew on the flow control valve.
How do I avoid disturbances during drilling?
In order to avoid disturbances during drilling and damage to the fan drive, set the alarm at the fan speed in the DrillManager, see DrillManager instructions.
What should I clean at regular intervals to prevent overheating?
The radiator fins must be cleaned at regular intervals, as otherwise the cooling and fan air flow will be reduced. The hydraulic oil could overheat and cause clogging of the seed hoses.
What should I ensure during assembly?
During assembly the PTO-shaft driven pump is plugged on the drive stub. With the brackets the pump must be tightly fastened to the tractor, but without distortion. The pump must not move during operation, since this would cause damage to shaft and bearings.
What should I check and maintain regarding the fan with PTO-shaft driven pump?
Ensure a free flow return pressure of max. 2 bar, check the oil level, clean fan protection grille and radiator fins from dirt, clean fan wings from dirt, change oil and filter, if required, and retighten the clamping taper on the fan shaft.
How often should the conical clamp be re-tightened?
The conical clamp should, therefore, be re-tightened after approx. 50 operating hours and checked once per year.
What should I do before re-tightening the clamping screws?
Therefore a loose flange must be aligned closer to the hydraulic motor. The clamping surfaces must be free of oil and grease.
How should I tighten the clamping bolts?
The clamping bolts must be tightened as evenly as possible in several steps. In between, tap the flange lightly (plastic hammer or hammer handle) to facilitate mounting on the cone.
What is the torque specification for imperial screws?
The imperial screws in the version no. 10 – 24 4.6 must be tightened to a max. torque of 6.8 Nm.
What should I check after tightening?
After tightening, check the impeller for free and even running.
What should I keep closed to protect the seed?
The tarpaulin should always be kept closed to protect the seed against contamination, dust and moisture.
What should I avoid to prevent metering faults and unnecessary wear?
In case of extreme development of dust, this dust can deposit in the hopper and fill up the roller flutes. This causes metering faults and unnecessary wear inside the metering unit.
How is the cover used for calibrating?
For the purpose of calibrating the cover is opened and the calibration bag is hooked on to the hooks on the housing.
What should I avoid in order to prevent malfunctions in the injector nozzle?
In order to avoid malfunctions in the injector nozzle or on the seed transport or the distribution during the seed placement, all connections and the lid must be tightly closed.
What leads to metering errors?
Air leaks lead to metering errors.
What must be free to ensure proper function of the air separator?
The holes must be free, so that this function is not impaired.
What should I regularly check for when using an air separator?
Especially for large amounts of seed these bores must be regularly checked for unrestricted escape of air and deposits must be removed. At the same time check seed hoses and distribution box for clogging.
What should I do if there is a risk of clogging in the seed hoses?
In this case the fan speed must be raised or the air loss at the screen ring must be reduced. For this purpose the hose can be pushed further over the air separator or an additional clamp may be installed.
What should I check before starting work?
Seed placement and distribution box must be checked before starting work and at regular intervals during sowing.
How can the half-width be manually switched?
On all machines with a distributor tower the half-width can be manually switched with the distributor cover.
How do I use the cover for half-width shut down?
Unscrew the distributor cover and reinsert it into the tower with the plate facing down. Make sure that the “correct” side has been shut down and check the air flow on the coulters of the still open half with the fan running.
How should I adjust the seed quantity with the half-width cover in place?
With the half-width cover in place the seed quantity in the terminal must be halved.
How can the seed quantity be reduced?
The seed quantity can be reduced down to 50%: either via the % adjustment button, or by entering just half of the desired seed quantity under “Seed quantity kg/ha”. In both cases the drilled area is counted over the entire machine width.
What must be halved if the correct area is strictly required?
If the correct area is strictly required, the working width must be halved in the machine configuration. The seed quantity must in this case not be manually changed.
What should I consider if a tram line is required with half-width shut down enabled?
If a tram line is required with half-width shut down enabled, one must consider the installation position of the valves. Hoses may need to be replugged or adapted to the control.
What can I do if the switched off half-width is equipped with sensors for seed flow monitoring?
You can either switch off the seed flow monitoring, or unplug the sensors and correct their number in the machine configuration.
How do I switch off the desired half-width in the terminal?
Switch off the desired half-width in the terminal. The valve is adjusted – the display flashes.
What happens to the seed flow monitoring with half-width shut down?
Seed flow monitoring is automatically switched off.
What may be necessary in case of significant weight differences of the quantities to be placed?
In case of significant weight differences of the quantities to be placed, e.g. with rape and fertiliser, it may be necessary to match the air quantity to the placement quantity.
How do I match the air quantity?
For this purpose loosen the nut on the seed hose and slightly adjust the valve. The higher air quantity must be directed to the higher placing quantity – follow the adjustment table for the fan speed.
What should be determined by field tests?
The correct distribution must be determined by field tests and should be checked when starting and during work. The air valve must be adjusted before starting sowing. This setting must be checked every day.
What should I check whenever opening the hoppers?
Whenever opening the hoppers, they must be checked for leak tightness with the fan running. Switch on the fan and feel with your hands around the lid and listen for escaping air. In case of leaks replace the seals or readjust hinges and locks.
What may cause heavy starting of the metering unit?
If the twin hoppers are used to transport fertiliser over a longer or bumpy distance, the fertiliser may solidify inside the hoppers. This may cause heavy starting of the metering unit and there is a danger of bridging in the hopper.
What should I do if fertiliser solidifies inside the hoppers?
The fertiliser must in this case be re-turned to a flowing state, before it is placed.
How can I exchange the volume ratios of the two hoppers?
Change the cell wheels in the metering units, fill fertiliser into the front and seed into the rear hopper, switch the valves in the Venturi areas over to the opposite side and lock them, and enter the new quantities in the terminal for metering unit I and II and perform calibration.
What should I do if no fertilizer is to be placed?
If no fertiliser is to ve placed, both hoppers can be used for seed. We recommend to use the “2 x seed” function in the DrillManager. In this case the computer will control both metering units in such a way, that both hoppers will be empty at the same time.
How do I use both hoppers for seed?
In both Venturi areas switch over the valves in the air flow for the seed distributor tower and lock them, a blind cover must be inserted into he distributor in the fertiliser hopper, so that the air inside the pressure tank cannot escape through the fertiliser hoses, set the valve in the air distributor hose in middle position, fit both metering units with cell wheels for approx. half the seed quantity (if the two are not identical, install the larger cell wheel into the rear hopper), and in the terminal “Machine configuration page 1” select menu option “Fertiliser control” – “2 x seed” and confirm the hopper ratio of 60:40 (then calibrate both metering units – see “DrillManager” instructions).
What must be done for both metering units with half-width shut down?
in this version both metering quantities are halved and the settings made in the terminal must be made for both metering units.
What settings must be made in the terminal for both metering units?
Both metering quantities can be e.g. reduced to 50% via the %-adjustment button. Please make sure that both metering units are switched “ON” on the page “Machine data” un-der “Delta Step”. One can also enter half of the desired quantities for both metering units in kg/ha. In both cases the drilled area is counted over the entire machine width.
What must be halved if the correct area is strictly required with half-width shut down?
If the correct area is strictly required, the working width must be halved in the machine configuration. The seed and fertiliser quantity must in this case not be manually changed.
What must be considered if a tram line is required with half-width shut down enabled?
If a tram line is required with half-width shut down enabled, one must consider the installation position of the valves. Hoses may need to be replugged or adapted to the control.
How do I test the half-width shut down function?
The half-width shut down function must be tested in the field.
What should I check in case of malfunctions with middle position sensors?
In case of malfunctions one must check the set-ting and the switching function of the sensors. Both valves must be in the same position and both sensors must switch a signal when in mid-dle position.
What should I check regularly?
The distribution head must regularly be checked for foreign matter. Unscrew the distributor cover and check the outlets. Check all components and connections regularly for leaks. Check the function and position of the tram line valves. Check the correct order of the seed flow sensors.
What has to be regularly checked regarding the scrapers?
Readjustment, impact and wear to the scrapers has to be regularly checked.
What has to be adjusted if the coulter discs are renewed?
If the coulter discs are renewed, the preliminary tension of both coulter discs has to be adjusted by means of the washers. Some preliminary tension has to be applied to the coulter discs on the edge, but they still have to be able to be easily rotated without applying any force.
What function has to be observed?
The function of the scrapers has to be observed. If these have already been run in and a wear edge has formed, then this edge is not allowed to touch against the outside of the cutting edge, because otherwise automatic re-adjustment would not be possible. Add a further disc or renew the scraper if necessary.
What should you keep free of oil?
Keep the rubber bearings free of oil. Oils and grease can damage the rubber and have a negative effect on the function.
What happens if the uniformer picks up residue in the event of wet and sticky soil conditions?
The uniformer can pick up residue in the event of wet and sticky soil conditions, in this case it should be dismantled. If the machine is lowered it should not be put into reverse so as not to damage the uniformer.
What are the press wheels responsible for?
The press wheels are fixed to the seed arm with a grid tooth system. They are responsible for the depth control of the seed placement, cover the seed with fine soil and press this onto the seed.
What keeps the press wheels free of dirt, and what can you do if needed?
A scraper keeps the press wheels free of dirt. The scraper can be reset, if necessary.
What can you do if the press wheels do not provide depth control in soft or sandy soil conditions?
If the press wheels do not provide depth control in soft or sandy soil conditions, they can be replaced with 10 cm wide press wheels.
What maintenance should you check for the seed arm bearing?
Check the condition of seed arm bearing (rubber). Renew depending on level of deterioration or in case of a slackness in tension force.
What maintenance should you check for the press wheels?
Check the press wheels for condition and ease of movement and check retaining screw on the grid tooth system for tight fitting.
What maintenance should you check for the coulter discs and bearings?
Check the coulter discs and bearings for wear, preliminary tension and ease of movement.
What torque should you tighten the coulter screws with?
Tighten the coulter screws with 130 to 150 Nm.
What maintenance should you check for the scraper and uniformer?
Check the scraper and uniformer for condition, tight fitting and adjustment.
How to Adjust Coulter Stop Position?
- Fully extend machine.
- Turn the coulter pressure control back in order to relieve the rubbers so that they will not lose their tensioning force.
- Lift the coulter at the rear, check for play and preliminary tension.
- The rail has to be reset, if it shows any play and the coulter brackets hit on the rail.
- Lower the machine.
- Adjust the coulter rail down by approx 5 mm.
- Lift the machine and check preliminary tension again.
What must be assured with all work on the metering unit?
Absolute leak tightness of components must be assured with all work on the metering unit. Leaks lead to metering errors.
What must be avoided when assembling the metering unit?
When assembling the metering unit all contact faces must be sealed and distortion of the housing caused by screwing on must be avoided.
When performing assembly work on the motor, how should you always mount it?
Whenever performing assembly work on the motor, you should always mount it with the bore facing down, so that no water can run into the housing.
What should you do when changing the roller?
The seed hopper should be empty when changing the roller.
- Unscrew the side cover.
- Pull out the roller with the drive shaft.
How to change the roller?
- Remove lock washer and washer.
- Pull out the drive shaft and assemble the new roller.
The drive shaft requires axial clearance in the roller for self-cleaning of the roller in the metering housing.
What should you check after each roller change?
The setting of sealing lip and the concentricity of the roller must be checked after each roller change.
How to change roller with full hopper?
- Unscrew the wing screws on side cover and drive motor, take off side cover and motor.
- Remove lock washer and washer from the drive shaft.
- Plug the new cell roller on the drive shaft and use it to push the old roller out of the motor side.
- Fix the drive shaft, assemble and fasten side cover and motor.
What must be done to avoid malfunction when sowing fine seed?
In order to avoid malfunction when sowing fine seed, the cell rollers are completely pre-assembled in the factory.
What happens during sowing with the cell discs in the roller?
During sowing only the cell discs in the roller will rotate, the spacers are stopped from rotating by stops on the housing.
What causes metering errors during sowing, and what should you replace at least 1 x per year?
A defective sealing lip or an incorrectly assembled supporting plate causes metering errors during sowing. The sealing lip must not be torn or damage – replace the sealing lip at least 1 x per year.
When using normal and fine seeds, which side must face towards the roller?
With all normal and fine seeds the wider side must face towards the roller.
What should you do in case of disturbances with coarse seeds such as maize, beans etc.?
In case of disturbances with coarse seeds such as maize, beans etc. both the retaining plate and the sealing lip can be replaced by a wider design.
How to replace the sealing lip?
- Take out the rotor.
- Insert the side cover with the new sealing lip, tighten the sealing lip only to such an extent, that it can still be moved in axial direction.
- Move the lip, so that it projects approx. 1 mm into the roller recess.
- Take off the side cover, do not move the lip any more and tighten it.
- Assemble the side cover, check the setting once again and reassemble roller.
How to assemble the rollers?
The anti-rotation locks must be turned towards the recess in the housing in order to remove and assemble the rollers.
What maintenance is required for fine seed rollers?
The function and operability of fine seed rollers must be checked every day.
- There should be no gap between the cell discs. If the gap is too big, additional shims must be added.
- The cell discs must be light turning. Dressing or similar materials must not block cell discs or bearings.
- The safety clips must be in place and correctly assembled to avoid the formation of a gap.
How are cell discs and spacers assembled?
Cell discs and spacers are assembled with shims to keep the roller assembly tight, thus ensuring that no seed will enter between cell discs and spacers.
What are the spacers equipped with?
The spacers are equipped with bearings. Depending on the manufacturing tolerance shims are added to avoid any friction between cell discs and spacers.
What should you do after the assembly of all parts?
After the assembly of all parts the remaining gap to the lock washer is filled up with shims. Finally assemble the lock washer. With the roller correctly assembled the cell discs between the spacers can just be freely turned. The parts should not rub against one another, but the clearance should be as small as possible. When checking against a light source the gap should just be visible.
What do the rape brushes do?
The rape brushes clean the cell discs in the rollers for fine seeds.
What must be done before sowing fine seeds?
Before sowing fine seeds the rape brushes must be installed in the side cover and their function must be checked.
- Check concentricity and fastening.
- Check condition and cleaning effect of brushes.
- Install the side cover with the brushes into the metering unit.
- The brushes must firmly rest against the cell discs and should rotate with the roller.
The function and cleaning effect of the rape brushes must be checked before starting sowing and at regular intervals during work.
What happens when cell discs are sticking?
Sticking cell discs cause metering errors during sowing. Less seed is metered.
When should the rape brushes be disassembled?
The rape brushes should be disassembled when sowing normal seeds. The housing holes must be closed.
How to perform a function test?
After installing a new roller the function and concentricity of the new roller must be checked. For this purpose switch on the roller as described in the section “Calibration test”.
- The drive motor must run “smoothly”. No stiff points should be recognizable.
Untrue running causes inaccurate metering and may overload the motor.
- If possible locate the stiff point.
- Rework damaged parts (by machining …) or replace.
- Loosen the screws on the side covers for drive motor and roller bearing and realign the side covers to release tension.
- If the drive shaft has been bent, realign or replace it.
- Remove any foreign bodies that may have been jammed between roller and housing.
- If dust or dressing in the roller has entered between cell discs and spacers dismantle and clean the roller.
What may be added to the seed if large seed grains partly have poor trickling characteristics?
Large seed grains partly have poor trickling characteristics and thus do not fill the roller flutes completely. In such cases talcum powder or graphite powder may be added to the seed.
When must you install and adjust the wider sealing lip?
When using the adapter frame you must install and adjust the wider sealing lip – see adjusting the sealing lip. The special rotors for coarse seeds should in this case be used. These are available in different sizes to match the different working widths and seed quantities.
For sowing coarse seed (maize, beans, peas, etc.) what must one use?
For sowing coarse seed (maize, beans, peas, etc.) one must use the metering unit.
- A deflector must be installed instead of the rape brushes. This deflector prevents large seed grains from getting caught between rotor and housing, being crushed and thus blocking the rotor.
- For very large grains you may install an adapter frame. For large grains this eases the entry into the metering unit and prevents grains from being damaged.
What should you do if under extreme conditions overpressure can block the seed flow in the hopper?
Under extreme conditions overpressure can block the seed flow in the hopper. This causes seed failure. You should therefore always check the function of the pneumatic system and the placement of seed, especially with high seed quantities and working speeds. No grains should remain on the surface of the field.
What should be done if grains are blown out?
If grains are blown out, the fan speed needs to be increased (short-term up to 4000 rpm) or the working speed must be reduced, until the injector system works correctly again.
What happens when the max seed quantity is exceeded?
Exceeding this quantity results in a dynamic pressure at the injector nozzle. This may blow seed out through the perforated plate, which leads to a strip-like emerging of the seeds. These grains are visible on the surface of the field before they are covered by the packer or the harrow.
What servicing does the metering unit require?
The metering unit does not require any specific maintenance. In order to avoid repair related downtimes, both the metering unit and the drive motor should be cleaned and subjected to a function test after the end of the season. The bearings in the side cover in particular can be damaged or may become hard moving because of dressing dust. If necessary keep bearings in stock and replace in due time.
What should you do in case of cable breakage or repair work on the plug?
In case of cable breakage or repair work on the plug, the cables can be connected by soldering. However, the use of crimping contacts is recommended.
When should you perform calibration?
Perform calibration only when the machine has been lowered and is stationary.
What should you not use with seed?
Do not use sticky dressings with seed. These influence the metering accuracy. Check seed and hopper for foreign objects!
- Depending on the seed install the rape brushes or, for coarse seeds, the adapter frame, the deflector plate and the wide sealing lip. For grain and fertiliser disassemble the accessory parts. Check all side covers on the metering unit.
- Install the appropriate roller for the seed/ fertiliser quantity and check for true running.
- Check condition and correct setting of sealing lip.
- Fill the hopper with seed / fertiliser. Only fill in small amounts of fine seeds.
- Open the flap or cover on the Venturi area.
- Check and clear the Venturi area and the pipes of any dirt and seed deposits. Attach the calibration bag or slide it in along the rails.
- Calibrate the machine (see DrillManager instructions).
- Close the flap / cover. Ensure air tightness!
What risk is there if the machine is calibrated in folded condition?
If the machine is calibrated in folded condition, there is a risk of head or eye injuries. Wear appropriate protective clothing.
What should you do when weighing the calibration quantity?
Attach the scales at the dedicated location. When weighing the calibration quantity make sure that the calibration bag is freely suspended. If the bag rest on or touches the machine, the measured weight might be incorrect and adversely affect the complete drilling process.
What happens under extreme circumstances when placing too much pressure to the coulters?
Under extreme circumstances placing too much pressure to the coulters will have the opposite effect and the frame is slightly lifted by the pressure rollers, or the pressure rollers will submerge in the soil and the correct depth setting can no longer be assured.
What do changes to the hydraulic cylinder mainly effect?
Changes to the hydraulic cylinder mainly effect the drilling depth, but also the coulter pressure and the press rollers. Changes to the coulter pressure adjustment mainly effect coulters and press rollers, but also have an influence on the drilling depth. With each alteration one must therefore check the drilling depth and the effect of the press rollers on consolidation and depth guidance.
How is the drilling depth determined?
The drilling depth is determined by the height setting of the machine on the hydraulic cylinders and the pressure setting on the drill coulters. The fine tuning of adjustment possibilities must be matched to the soil conditions and can thus only be found in the field using operating position.
How do you adjust the seed placement?
To adjust the seed placement extend the hydraulic cylinders and adjust the coulter pressure with the screw, as described for the depth adjustment. This adjustment must take place at a “normal location” in the field. In case of difficult or hard areas in the field the coulter pressure can then be raised during sowing. The controlled pressure is indicated by the pressure gauge. Extend the cylinders again when meeting “normal” soil conditions.
How do you increase the coulter pressure?
The coulter pressure can be increased by backing out the screw adjustment.
What happens when lowering the machine?
When lowering, the weight of the machine is transferred to the drill frame. The height is limited by aluminum clips on the hydraulic cylinders. The resulting pressure is transferred to coulters and press roller via the rubber elements.
How to find the correct setting by trying and testing?
- Turn the coulter pressure adjustment back to a low pressure.
- Insert the same quantity and colour combination of aluminium clips on the hydraulic cylinders.
- Lower the machine in operating position on the aluminium clips and drive a few meters in the field.
- Level the machine by the tractor link arms or the articulated drawbar.
- Check the coulter seed depth and the consolidation by the press wheels.
- If necessary increase the coulter pressure and check for changes after driving a few meters in the field.
If the desired adjustment cannot be found within the coulter pressure adjustment range, the process must be repeated using the next lower setting on the hydraulic cylinder, until the correct setting is found. Always insert the same amount and colour combination of aluminium clips on all hydraulic cylinders of the packers and adjust all rods on the coulter pressure adjustment evenly.
What could happen if you do not drive without clips?
Do not drive without clips. The coulter frame could rest on the packer shaft and cause abrasion. If the depth is not reached, the press roller can be adjusted one tooth up.
What must be preloaded on foldable machines?
On foldable machines the wing hydraulics must be preloaded with min. 80 bar, to prevent the wings from being raised during the drilling process.
How should the machine be leveled in the field?
In the field the machine must be levelled with the tractor link arms, in case of an articulated drawbar by using the depth setting. On machines with articulated drawbar aluminium clips must be inserted on the hydraulic cylinder and the machine must then be lowered on these clips. Switch the lock valve to position “Field”. With two-point hitching the tractor link arms must be locked in position hydraulically or mechanically. On front packer machines the hitching hydraulics must be switched to floating position. At the headland the machine is lifted out only at the rear by the packer.
How should the depth setting be matched to the soil conditions?
The depth setting must be matched to the soil conditions. The harder the ground and the deeper the cultivation tools need to work, the higher the required preload of the rubber elements.
How is the depth of the pre-work tools set?
The depth of the pre-work tools is set by it’s own control unit. Once the setting is completed, reposition the control unit in neutral position. The working depth is indicated by an indicator on the front of the hopper. When lifting the machine the pre-tools remain at the adjusted working depth. The desired working depth can be adjusted and changed during work.
What maintenance should you check on the coulter discs?
Check the bearing (rubber); replace if rubber is worn or in the case of weakening tensioning force.
Bearings are oil-filled and therefore maintenance free.
Check the discs regularly for clearance,oil leaks and free rotation.
What happens if water has entered mechanical seals and the machine is then parked over a longer period of time?
The mechanical seals are very sensitive if water has entered and the machine is then parked over a longer period of time. This can cause corrosion and both mechanical seal rings may stick together. The mechanical seal rings will then rotate around the O-ring and damage it. Oil would run out and the bearing would be damaged after a short while.
- Bearings must therefore not be cleaned with high pressure cleaning equipment.
- Before longer periods of rest the bearing locations should be sprayed with a rust dissolver or similar.
- Before resuming operation the discs should be turned by hand and checked for free rotation.
How to park the machine?
In order to avoid damage caused by moisture the machine should preferably be parked in a barn or under a roof.
- Park the machine on level and solid ground.
- Use the support on the seed wagon.
- Turn the coulter pressure control back in order to relieve the rubbers so that they will not lose their tensioning force.
- Disconnect electrical and hydraulic connections from the tractor. Hook the plug connectors to the brackets provided for this purpose.
- Unhitch the machine.
- Empty the seed/fertiliser hopper.
- Clean the metering units.
- Close the tank lid/cover. Do not clamp the tank lid, to protect the seal.
- Store the DrillManager terminal in a dry room.
- Keep rubber elements free of oil and grease.
- Equipment with pneumatic brake; drain air reservoir and seal hose couplings during longer downtime periods.
- Apply the parking brake. For longer downtimes secure the machine in any other way against rolling, to prevent the brake pads from sticking to the drums, making restarting more difficult.
Thoroughly clean the machine and hopper if solid fertiliser was used. Fertiliser is aggressive and speeds up the corrosion process. It especially attacks galvanised components.
What does the speed depend on?
The speed depends on field conditions, soil type, harvest residues, seed, seed quantity and other factors. Operate somewhat slower under difficult conditions.
What should you do during sowing while turning?
During sowing the engine rpm should only be reduced shortly before raising the drill, so that the fan output does not drop too much and cause the hoses to block. Lift out the machine during travel and do not reverse in lowered condition. After turning on the headland position the machine approx. 2 to 5 m in front of the seed bed with the appropriate fan speed. The seed requires some time to flow from the metering unit to the coulters. The operation switch will only release the signal after the pressure in the lifting hydraulics (floating position) has dropped below 50 bar.
What should be done after sowing?
Seed hopper and metering unit should be emptied and cleaned after sowing. Seed and dressing could become moist overnight and clog. This could result in seed bridging in the seed hopper and sticking to the flutes of the roller. Metering and seed errors could occur.
The seed hopper can be emptied through the clearing valve on the side. For this purpose use a suitable container and open the gate valve. Residues can be emptied through the Venturi area.
What does the sowing quality essentially depend on?
The sowing quality essentially depends on the adjustments and checks made prior to and during sowing, as well as on regular servicing and maintenance of the machine. Before starting sowing you should therefore carry out all maintenance and lubrication work.
What checks should you do before and during sowing for the machine?
- Has the machine been hitched up correctly and are the coupling devices locked?
- Have the hydraulic lines been connected without being mixed up by mistake?
- Have the tractor link arms in two-point hitching been laterally locked?
- Have the safety catches been engaged for road travel and does the light system work properly?
- Has the piston rod of the undercarriage cylinder been filled up with aluminium clips for road transportation and has the machine been lowered on these clips?
- Is the wing hydraulics pre-loaded with min. 80 bar in working position?
- Have the bout markers been set to the correct length?
- Is the machine completely raised or do the tractor link arms need to be limited in depth?
- Has the lifting hydraulics been switched to float position for sowing?
- Has the machine been levelled and the drilling depth correctly adjusted?
What checks should you do before and during sowing for cultivation tools?
- Are coulters, harrows (wear items) and other cultivation tools and optional equipment still in a serviceable state?
- Do the coulters have sufficient pretension and do they all rotate freely?
- Are the scrapers still in good condition and correctly adjusted?
- Are packer rollers and packer bearings in good order?
What checks should you do before and during sowing for the fan?
- Is the hydraulic fan connected to a pressure free return flow?
- Is the PTO-shaft driven pump correctly mounted?
- Are oil level and filter for the PTO-shaft driven pump OK?
- Are fan and intake grill clean?
- Is the fan tightly mounted on the shaft?
- Are fan speed and drive pressure not exceeded?
- Has the fan speed been set according to the table?
What checks should you do before and during sowing for the pneumatic system?
- Are tram line valves installed in the correct seed lines for the tram lines?
- Has the tram line rhythm been adjusted and do the wings operate?
- Are the seed lines for tram lines completely closed and completely opened?
- Are the seed hoses free of sagging, water and other deposits?
- Are all air lines between fan and coulters leak tight and firmly connected?
- Does air flow out uniformly out of all coulters?
- Has the air volume been set correctly on the fan? Does the seed bounce out of the seed furrow, or remain in the pipes and cause blockage?
- Is the air separator on the (Pronto 3 and 4 DC) head free of blockage and deposits?
- Depending on fan design on dual hopper version, is the air valve in the distribution head in middle position?
What checks should you do before and during sowing for the metering unit?
- Is the sealing lip in the metering unit still OK and adjusted (replace the sealing lip 1 x per year)?
- In the case of small seed, have the cleaning brushes been installed and are they in serviceable condition?
- Has the deflector plate and, if necessary, the intermediate frame and the wide sealing lip been installed for coarse seeds?
- Have symmetrical rotors been installed for half width shut off and double Venturi areas?
- Are all connections air tight and has the clearing valve been closed firmly and leak free?
- Is seed coming out of all coulters?
- Are bridges forming in the hopper (particularly with husky seed and fertiliser)?
- Is, especially in the case of small seed, the correct seed quantity being distributed?
- Is seed being blown out through the grill?
When sowing, these checks must be carried out at the beginning of work and, in case of larger fields, at regular intervals during work!
How should the machine be carried during sowing?
During sowing the machine is carried in height by the packers at front and rear. For this purpose the hydraulic system must be switched to floating position. Do not load the front packer by applying additional hydraulic pressure. In case of soft soils slightly relieve the front packer via the tractor hydraulics.
What maintenance is required for the front packer?
- Check packer shafts for concentricity and fastening.
- Check air pressure, fastening and condition of packer tyres.
How does the DrillManager react in case of a coulter pressure adjustment?
In case of a coulter pressure adjustment the DrillManager receives a signal and is then able to automatically adjust the seed and fertiliser quantity. This function can be enabled and disabled in the terminal. When switched “On” the metering quantity is increased by the “Delta Step” percentage value – see DrillManager instructions.
What should you do when using track loosening discs?
When using track loosening discs, the coulter brackets are replaced by adjustable brackets. The brackets can be adjusted in four stages and thereby press the coulter discs deeper into the ground. Depending on the width of the tractor track you can install one or two adjustable disc pairs.
How are the track loosening tines?
The tines are spring loaded and can be adjusted in height and distance. Several tines can also be installed, if required.
How to adjust the marker depth?
The marker depth can be adjusted by the bracket via bolt and adjustment holes. Using the upper hole stops the arm and marking is disabled.
- Check free movement and clearance of bearings.
- Check hydraulic valve function and disc mark before starting work.
- Check coulter discs for wear.
How can the cutting angle of the coulter discs be adjusted?
The cutting angle of the coulter discs can be adjusted to suit the soil conditions and the requested marker depth by rotating the disc angle. Simply release the bracket and rotate the four-cornered shaft until the requested coulter disc angle is attained. Then tighten the screws again. For an aggressive adjustment the delivery includes an additional set of brackets, which can then be used for replacement.
How to make adjustments to the harrow in front of packer?
The adjustment is made with the bolts in the hole matrix.
- Lift the machine and unload the harrow.
- Remove the bolts and reinsert them as required for working depth, harvesting residues and field conditions.
- If there is a risk of blockage or in case of high harvesting residues, the harrow can be swivelled up and locked in top position.
Insert all bolts in the same position.
How are the tines on the rear harrow adjusted?
At the rear the harrow is guided by the pressure rollers, the brackets are spring loaded and individually fastened to the seed coulter frame. The tines can be adjusted in height and must be matched to soil conditions and harvest residues before work is started. The tines can be lowered to compensate wear or to increase the pre-tension.
How are the hydraulic cylinders adjusted on Pronto 4 and 6 DC?
The hydraulic cylinders on Pronto 4 and 6 DC are connected in series. In order to assure synchronism of the cylinders and perfect adjustment of all piston rods to the end stop, all cylinders should be completely extended before starting work.
What must be done when lowering the machine?
The fertiliser discs are always raised when the machine is lifted out. When lowering, the machine must be lowered under pressure, until all discs have ground contact. Thereafter, switch the control unit to the floating position.
How should the division of the fan air flow be tested?
The correct division of the fan air flow must be tested in the field under seed placement conditions. When set correctly, no seed blockage should occur in either of the systems and no seed or fertiliser should be blown out of the furrows or out of the grill. The fertiliser placement must be checked before starting work and, when processing large fields, also in-between.
How to adjust depth for fertilizer placement?
For depth adjustment the bolt is used as stop for the hydraulic cylinder. The sticker shows the position of bolt 1 = shallow to 7 = deep. All bolts must be positioned in the same setting.
What happens if the discs touch the soil in raised position?
In raised position the discs should not touch the soil. The discs would in this case wear off non-circular and could no longer be used. In this case it would be better not to shut off the coulters and allow them to rotate in the soil.
What maintenance is required for the fertilizer equipment PPF?
Bearings are oil-filled and therefore maintenance free.
- Check the discs regularly for clearance, leak tightness, wear and free rotation.
- Check the drill arm bearing (rubber); replace if aged or the tensioning force has diminished.
- In case of wear on the coulter discs you must adjust the fertiliser pipes higher, to make sure that they will not be ground off in the soil. Loosen both screws and fasten the pipe again slightly higher. Adjust the pipes to the same height on all fertiliser discs.
What must you do if no fertiliser is to be placed?
If no fertiliser is to be placed, the fertiliser quantity must be set to 0 kg/ha in the DrillManager and the metering unit can be switched off. In raised position the seed coulters can be shut off with a cock valve.
What happens if there are air losses in the pneumatic system?
The hoses and components of the pneumatic system must be leak tight and firmly attached. Air losses will have a negative effect on the distribution. The distributor must be regularly checked and cleaned from dirt and deposits. Valves for tramline control can be installed, if demanded.
What does the required air quantity depend on?
The required air quantity depends on seed (type and weight), seed quantity, working width and sowing speed. A correct fan speed cannot be specified and must therefore be determined by tests in the field.
What should the airflow not be?
The air flow should not be higher than necessary. The seed must not be blown out through the grille on the metering unit (see metering unit). It must, however, not be too weak, so that the seed does not remain in the hoses and cause blockage. Too weak an air flow may also have a negative effect on the distribution. The fan speed must be adjusted to the field conditions. Depending on working width and seed a fan speed of min. 2000 to 3000 rpm is recommended in order to achieve uniform transverse distribution.
When should fan setting, seed transportation and seed placement must be checked?
Fan setting, seed transportation and seed placement must be checked when starting sowing, and also at regular intervals when working on large areas.
