The depth guidance takes place in the field using the front support wheels and the packer. Depending on the model, adjustment is done either mechanically or hydraulically.

WARNING: Danger of injury. Make sure before setting the working depth that no persons are present in the danger zone.

For the manual depth setting, the working depth is adjusted with aluminium clips. The aluminium clips for depth setting are plugged on the setting bars.

The clips can only be removed, respectively inserted when the respective side is without load. It is therefore necessary to raise or lower the machine so that either the packer or the support wheels are loaded or relieved.

– Plug the clips in the same amount and colour on the support wheels on both adjustment rods.

– Plug the clips in the same amount and colour on all adjustment rods of the packer.

– Always fill all adjustment areas (1) and (2) completely with clips, if this is possible.

– Place clips not needed in area (3).

– Align the machine or the disc rows as horizontally as possible (e.g. in case of double camber).

– On loose, ploughed soil with low load bearing capacity: Adjust the machine to a shallower working depth by the adjustment rods for the support wheels than on the packer. The machine thereby works shallower with the front row of discs than with the rear ones.

– Slightly lift the machine by drawbar and undercarriage.

– Remove clips from area (1).

– Lower the machine.

– Reinsert the clips again in the area (2).

– Lower the machine by drawbar and undercarriage.

– Move forward by a few metres in the field.

– Remove clips from area (2).

– Lifting the machine.

– Reinsert the clips again in the area (1). With the cylinders fully extended (area (2) no clips) the coulters will just touch the ground.

Note the ratio of approx. 1:1.5 with the Joker 5/6 RT. Example: In order to change the working depth by 3 cm, reposition clips with a total thickness of 2 cm (2x red). See chapter Aluminium clips.

With the hydraulic system the working depth can also be set and adjusted while working in the field.

Levelling: The hydraulic cylinders are connected in the rephasing system (connected in series). Therefore by depth changes the machine always moves parallel to the working surface. To even out differences, the cylinders must be levelled.

NOTE (Equalize): Equalize before beginning to work, before depth setting as well as several times during the working day!

– Lift the machine completely.

– Operate the control unit for depth setting and fully extend all cylinders.

– Continue holding pressure on the control for approx. another 5 seconds, until all cylinders are fully extended and filled.

– Repeat this procedure 2 – 3 times.

Setting the depth:

– In the field lower the machine and raise the undercarriage completely.

– Switch the control unit for the hydraulic cylinders of the drawbar to floating position.

– Operate the control unit for depth setting and lower the machine to the desired working depth. Observe the associated scale (0-15) on the support wheel.

– Switch the control unit for depth adjustment to locked position.

A shallower working depth than on the packer can be preset on the cylinders of the support wheels (e.g. for loose, ploughed soil with low load bearing capacity). The machine thereby works shallower with the front row of discs than with the rear ones.

– Lift the undercarriage and thereby lower the machine onto packer and support wheels.

– Remove clips from area (1).

– Lower the undercarriage to relieve the support wheels.

– Insert the clips into the resulting gap (2).

– Use the same amount and colour of clips on both cylinders.

– Note the ratio of approx. 1:1.5.

– Add no clips on the piston rod!

Depth guidance of the Joker 8 RT is done via the disc system. Adjust both rows of discs simultaneously via a coupling bar.

WARNING: Danger of injury. Make sure before setting the working depth that no persons are present in the danger zone.

For the manual depth setting, the working depth is adjusted with aluminium clips. Insert the aluminium clips into the hydraulic cylinders of the depth setting. The aluminium clips are plugged on the setting bars.

Adjusting the working depth:

– Extend the cylinders for the depth setting completely.

– Plug on the clips as needed (the working depth is 15 cm if the cylinder is completely extended).

– Pull in the cylinders to the stop position of the clips.

Note the ratio of approx. 1:1.2 with the Joker 8 RT. Example: In order to change the working depth by approx. 5 cm, reposition clips with a total thickness of 4.2 cm (6x blue).

With the hydraulic system the working depth can also be set and adjusted while working in the field.

Levelling: The hydraulic cylinders are connected in the rephasing system (connected in series). Therefore by depth changes the machine always moves parallel to the working surface. To even out differences, the cylinders must be levelled.

NOTE (Equalize): Equalize before beginning to work, before depth setting as well as several times during the working day!

– Lift the machine completely.

– Operate the control unit for depth setting and fully extend all cylinders.

– Continue holding pressure on the control for approx. another 5 seconds, until all cylinders are fully extended and filled.

– Repeat this procedure 2 – 3 times.

Setting the depth:

– In the field lower the machine and raise the undercarriage completely.

– Switch the control unit for the hydraulic cylinders of the drawbar to floating position.

– Operate the control unit for depth setting and lower the machine to the desired working depth. Observe the associated scale (0-15).

– Switch the control unit for depth adjustment to locked position.

– Unfold the machine in the field and adjust; see chapter Depth setting.

– Open the lock valve on the hydraulic cylinder of the drawbar.

– Machines with support wheels: Extend the hydraulic cylinder of the drawbar and remove the clips.

– Machines without support wheels: Align the machine horizontally with the help of the drawbar and fill up the cylinder of the drawbar with aluminium clips.

– Switch the control unit for the hydraulic cylinders of the drawbar to floating position.

– Switch the control unit for “Folding” to the locked position.

– Open the lock valve on the hydraulic hose of the cutting blade roller or crossbar (optional).

– You should only lower the undercarriage if the machine becomes stuck because of the prevailing soil conditions.

– Lift out the undercarriage completely.

– Open the lock valve of the pressure accumulator (if so equipped).

– Now lower the undercarriage again by approx. 2 cm.

The cylinders may become de-adjusted during work in the field.

Perform levelling of the cylinders several times a day:

– before starting work

– before depth setting / readjustment

– every 10 operating hours.

See Hydraulic depth setting.

– At the headland lift the machine out by the drawbar and turn around on the packer.

– You should therefore not lower the undercarriage.

The working quality essentially depends on the adjustments and checks made prior to and during use, as well as on regular care and maintenance of the machine.

– Carry out all maintenance tasks and adjustments before starting to work.

Checks before and during use on the field:

– Have the hydraulic lines been connected without being mixed up by mistake?

– Has the machine been secured for road travel and does the lighting work properly?

– Has the machine been levelled in working position and the working depth correctly adjusted?

– Are coulter, packer, harrow and other cultivation tools and optional equipment still in a serviceable state?

NOTE: Perform checks when starting work and with larger fields also regularly in between!

The position or height of each support wheel can be changed on the setting rods by placing aluminium clips. The clips may only be removed and inserted, respectively when the respective side is relieved. Depending on the intended setting, the machine must therefore be raised or lowered.

With the Joker 8 RT, the support wheels are adjustable for compensating the lateral pull.

WARNING: To make changes to the setting bars, the danger zone of the machine must be entered. Danger of injury by unintentional machine movements.

– Engage the parking brake of the tractor.

– Lock the hydraulic control units of the tractor.

– Make sure that the control units are not activated by a person inside the tractor!

– Observe the operating instructions and safety notes of the tractor manufacturer!

Adjustment details:

– The position of the support wheel is determined by the clips in the area (1). By default, 50 mm aluminium clips are placed.

– Note the ratio of approx. 1:1.5 with the Joker 5/6 RT. Example: To adjust the support wheel approx. 3 cm higher or lower, place or remove clips with a total thickness of 2 cm in the area (1).

– Note the ratio of approx. 1:3 with the Joker 8 RT. Example: To adjust the support wheel approx. 6 cm higher or lower, place or remove clips with a total thickness of 2 cm in the area (1).

– Always fill all adjustment areas (1) and (2) completely with clips, if this is possible.

– Insert clips, which are not required, in area (3).

– Lower the machine.

– Remove clips from area (2).

– Lift the machine.

– Place clips in area (1) (max. 100 mm).

– Slightly lift the machine.

– Remove clips from area (1).

– Lower the machine.

– Place clips in area (2).

– The bearings of the discs are filled with grease and therefore principally maintenance-free. Check the bearings regularly for clearance, leak tightness and even running after extended idle times.

– Tighten the screws of the coulter discs with 100 ± 20 Nm.

– Do not use adhesives for securing.

NOTE: Use appropriate tools (e.g. torque wrench) to be able to maintain the demanded tolerances!

The side limitation consists of a border disc (1) on one row and a spade disc (2) on the other row of discs. By default, the border discs are set to the middle position. Depending on operating conditions and wear, they can be adjusted toward the front or rear (3) as well as up and down (4).

To perform the adjustment, loosen the screws or dowel pin, adjust the border disc and fasten again.

2. Apply the parking brake.

3. Place wheel chocks under the wheels.

4. Loosen the brake line.

5. Disconnect the break-away cable from the tractor.

6. Unhitch the machine.

Unhitching does not trigger the breakaway brake. Emergency braking is only triggered if the spring cotter is turned to the front.

The valve has two positions:

A – operating position

B – emergency braking

The breakaway brake valve includes a manual brake releasing valve (1).

After emergency braking, the brake can also be released again without a tractor.

Turn the spring plug back to operating position and operate the releasing pump, until the brake is released.

– Check brake lines and hoses for signs of damage.

– Check the brake lining for wear.

DANGER: Uncontrolled rolling of the machine can cause severe injuries by crushing or rolling over. Park the machine only on level ground with sufficient load bearing capacity. Secure the machine with wheel chocks against rolling before releasing the brake.
