What is the general purpose of the Verti-Drain®?
The Verti-Drain® is a machine for aerating grass and sport fields. It is a 3-point machine that requires a tractor for use.
How do I take the Verti-Drain® off the pallet and prepare it for attachment?
The machine is placed vertically on the pallet. To remove the pallet and place the machine horizontally on the ground, follow these steps:
- Remove the PTO, PTO protective covers and pins from the machine.
- Attach a cable to the crane hooks. Make sure that the cable/crane/lift can hoist at least 2 times the weight of the machine (refer to technical data for weight).
- Lift the machine including the pallet by 50 mm (2″) off the ground. NEVER crawl under the machine!
- Remove the pallet (1 in Figure 8).
- Slowly lower the machine until the 3-point junction plates touch the ground.
- Slowly lower the machine further so that it can turn onto its front roller.
- Carefully lower the machine further until it stands on its front and rear roller.
- Assemble the PTO Cover 2 that is included with the supplied items.
- When the machine is taken off the pallet, remove the upper plug of the gearbox and replace it with the supplied breather.
How do I attach the Verti-Drain® to the tractor after removing it from the pallet?
After placing the machine horizontally on the ground:
- Attach the machine to a tractor. Use the proper tractor (refer to specifications).
- Attach the hydraulic hoses (if applicable) to the tractor.
- Lift the machine off the ground using the tractor’s 3-point hitch.
- Remove the locking pins of the rear roller (3 in Figure 8) and mount these in the appropriate hole for operation (4 in Figure 8).
- Place the machine on the ground and adjust the angle of the machine to 90° by turning the top rod. This 90° angle is very important for the proper functioning of the machine.
- Set the stabilizer of the tractor to 100 mm lateral stroke.
- Assemble the pins. Apply some grease to the spindle.
- Check and adjust the PTO length as needed (refer to Section 4.1).
What is important about the Power Take-Off (PTO) shaft?
The PTO is a very important item. It drives the machine from the tractor and ensures safe operations when correctly maintained and installed. The PTO shaft has its own CE certification; read the PTO shaft manual connected to the shaft itself. For specific adjustments, see the details on the PTO page in the parts book. Do not exceed the given values, as this can lead to unsafe situations and overload, resulting in damage.
Why is the length of the PTO important and what is the minimum overlap?
The length of the PTO is very important.
- If it is too long, it can damage the drive of the tractor and/or the Verti-Drain®.
- If the overlapping length of the cylinders becomes less than 250 mm (9.8″) at any time, it can damage the PTO.
How do I set the correct length for the PTO shaft?
To set the PTO to the correct length when a new one is purchased or a different tractor is used, follow these steps (refer to Figure 9):
- Measure the distance (A) between the PTO connection points (tractor to Verti-Drain, groove to groove) when the machine is connected to the tractor and positioned on the ground at the correct 90° angle.
- Measure the distance (B) of the PTO in its shortest position (locking pin to locking bolt).
- Divide the PTO into two parts and remove the protection cap at both ends.
- The ends of the cylinders and the ends of the protection caps must be made shorter by: (B – A) + 125 mm (4.9”).
- Smooth off all components, use some grease, and then assemble all components.
- Mount the PTO on the side of the Verti-Drain.
- Attach the other end of the PTO to the tractor.
- Check the overlap of the cylinders. It must always be a minimum of 250 mm (9.8″).
What checks are required for the correct use of the PTO?
The following items must be checked for correct use of the PTO:
- While working, the angle of the pivot pins may not exceed 30 degrees.
- The pivot pins must always be aligned.
- The overlap of the cylinders must always be a minimum of 250 mm (9.8″).
- Never use the machine if it has a damaged PTO protection cap.
- For lubrication see section 13.0: Maintenance.
How do I adjust the working depth of the Verti-Drain®?
The working depth can be adjusted when the machine is lifted (see Figure 10):
- Loosen the check nuts (1) on both sides of the machine.
- Turn the adjustment spindle (3) to set the depth according to the sticker (2). Adjust one side never more than 4 strokes at a time. Compensate the other side first before continuing.
- If the correct working depth is reached, tighten the check nuts (1) again.
How is the working depth indicated on the sticker affected by pin length?
The depth adjustment indicated on the stickers applies only if one uses pins of 225 mm (9″). If shorter pins are used, deduct the difference in length compared to the 225 mm (9″) from the values on the sticker to determine the actual working depth.
How can dragging of the rear roller be prevented during shallow pricking?
To prevent too much dragging of the rear roller in case of shallow pricking, pushing the protection pin (marked as 3 in Figure 8, used in hole 4 for normal operation) into one of the locking holes (5 in Figure 10) will block the rear roller.
How do I adjust the pin angle on the Verti-Drain®?
All pins can be adjusted simultaneously using the handles (4) at the side of the machine (see Figure 10):
- Raise the machine above the ground.
- Loosen the check nuts (5) on both sides of the machine.
- Adjust the angle by putting the supplied ring spanner on the hexagon (6) of the handle (4). The indicator (7) shows the angle.
- Remove the supplied ring spanner.
- Tighten the check nuts (5).
What do different pin angle settings (90°, 90°-70°) mean?
- A 90° angle means hardly any pin movement (kick). A 90° angle is required for hollow pins and is recommended for pins of 8 mm (5/16″).
- A 90°-70° angle means more pin movement (kick). This is recommended for solid pins and depends on the soil conditions, the pin measurement, and the requirements of the client.
What is the required combined drawbar length and how can it be calibrated?
The length of the combined drawbar (indicated by F in Figure 10) must be 457 mm (18″). This can be calibrated by means of shims (see Parts page). In case of 90°, the pins go into the ground perpendicularly only if the machine is correctly installed (drawbar length is correct). If the machine is incorrectly installed, a force F can occur which damages the machine.
How does driving speed relate to the distance between holes?
The driving speed determines the distance ‘D’ between the holes in the driving direction (see Figure 11). If a smaller distance between holes is required, you have to drive slower. Figure 11 provides a graph showing the correlation between driving speed (V) and hole distance (D) at a PTO speed of 540 rpm (crankshaft 460 rpm).
What is the maximum incoming PTO revolution speed?
The incoming revolutions of the PTO may be maximum 540 rpm.
What precautions should be taken regarding driving speed and potential hazards?
- If you expect hard objects, you must reduce the speed.
- The pin holders can start floating if using heavier pins, other applications, or maximum pin angle. Reduce the revolutions before the pin holders slam upwards.
- If the Verti-Drain is incorrectly attached (PTO angles different), vibrations can occur, damaging the machine and holes. Check attachment (Figure 8 reference in PDF).
- If the PTO is shortened incorrectly or if another tractor is used, the gearbox may be overloaded, causing damage.
What is the correct procedure for starting work with the Verti-Drain®?
The start procedure is VERY important to avoid serious damage. Follow these steps (see Figure 13):
- Move to the location where you want to start.
- Lower the machine until the lower pins almost touch the ground.
- Adjust the tractor engine to around 1200 rpm.
- Put the tractor in the correct gears and drive forwards (A).
- Engage the PTO (B).
- WHILE IT TURNS, lower the machine CAREFULLY into the ground DURING the forward drive (C).
- Increase the PTO’s revolutions to the maximum allowed value (max 540 rpm).
What is the correct procedure for stopping work with the Verti-Drain®?
Stopping occurs as follows:
- Decrease the engine revs to approx. 1200 rpm.
- Lift the machine off the ground.
- Detach the PTO as soon as the pins are out of the ground.
- Raise the machine further until the pins are minimum 120 mm above the ground.
- Go to the next location and start again as described in the start procedure.
What should be done if the machine is unstable during work?
During work, the front roller must be adjusted to the ground in a stable manner. If the machine is unstable, consider mounting other (lighter/shorter) pins or adjusting the working depth. Failing to eliminate instability will damage the machine, as it is NOT protected against this continuous overload.
What checks should be performed before using the Verti-Drain® in a specific location?
Before using the Verti-Drain® in a location, check the following:
- Loose objects: Are there loose objects in the field? Remove them first.
- Slopes: Are there slopes? The maximum slope is 20 degrees. Always go from top to bottom.
- Buried utilities: Are there cables/pipes buried in the ground? If so, determine their depth and adjust the working depth of the machine to 60% of that depth.
- Hard objects: Are there hard objects in the ground? If so, use the Verti-Drain® with a low PTO speed and adjust the working depth.
- Flying objects: Is there danger of flying objects (e.g., golf balls) distracting the driver? If so, the Verti-Drain® CANNOT be used.
- Ground stability: Is there danger of sinking/sliding away? If so, postpone using the Verti-Drain®.
- Ground condition (Frozen/Wet): If the soil is frozen or very wet, postpone activities until conditions improve.
- Ground condition (Compacted): If the soil is very compressed, use shorter pins or adjust the working depth.
How should the Verti-Drain® be transported?
The user is responsible for transporting the Verti-Drain® behind the tractor over public roads. Verify and comply with national legislation regarding regulations.
What is the maximum permitted speed when transporting the machine raised on open fields?
On open fields while the machine is raised, the maximum permitted speed is 12 km/h (8 mph) due to the weight of the Verti-Drain®. A higher speed can be dangerous for the driver and/or the public and can even damage the machine.
What is the minimum front axle weight requirement when the machine is raised?
When the machine is raised off the ground, the front axle of the tractor has to support minimum 20% of its weight for stability.
How do I detach the Verti-Drain® from the tractor?
Detach the machine in the following manner:
- Open the rear cover.
- Turn the crankshaft until all the pins are in the highest possible position.
- Place the machine with both rollers on a solid underground surface.
- Block the guide of the rear roller with the locking pins (3 in Figure 8).

- The kit includes plates (1).
- Attach the plates to the main bar using bolt (2), ring (3), and nut (4).
- Align the plates with the pins via the slotted holes in the plates.
- If plates bend after extensive use, attach them the other way around.
What other remarks are relevant for the turf-hold-down kit?
- If the pins are no longer in the centre of the machine (misaligned), they might touch the sides of the slots. Realign the pin locks.
- Check the length of the drawbar if the pins touch the front side of the hole during work activities.
What types of pins are available and what is important about using them?
Different pins (solid and hollow) are available. Use only original pins adjusted for the machine. Always use pins of the same thickness and length. Replace bent pins immediately to prevent instability. Do NOT use thicker/longer pins than supplied. Shorter (worn) pins can be used for superficial pricking, but the depth sticker reading will only be correct for full-length pins.
How should the locking bolts for the pins be tightened?
The pin holders have holes for attaching pins (4 x 12 mm, 2 x 24 mm).
- Tighten locking bolt A (smaller, top in Figure 18) with a torque of 40 Nm / 30 lbf.ft.
- Tighten locking bolt B (larger, side in Figure 18) with a torque of 70 Nm / 50 lbf.ft.
How should solid pins be used?
Solid pins break open hard compressed soil. The pin angle setting (Chapter 6.0) determines the pin movement (kick). More angle (towards 70°) gives more movement; 90° gives almost no movement.
What should be done if using new pins or if grass roots are weak?
New pins can damage weak lawns. First, clean pins manually or use the machine for 10 minutes on other rough underground. If roots are weak, adjust working depth slightly deeper than root length to encourage growth. Prick deeper next time. This prevents lawn damage and ensures healthy roots.
In which direction should the sharp point of solid pins face?
- For best pin movement in the soil: Use solid pins with the sharp point facing the direction of the front roller.
- For lawns with weak roots: Use pins with the sharp point facing the direction of the rear of the machine.
When are oval holes created and how can this be addressed?
Oval holes are created if the top layer is weak and the substrate has a hard layer. Use thinner pins or wait until the wet top layer has dried. If top dressing should be applied, apply this first *before* using the Verti-Drain. If soil is hard, sprinkle water, then use thinner/shorter pins or adjust depth. Failure to do so can damage the machine.
How should hollow pins be used?
Hollow pins are used for soil mingling and core removal. The opening of the pin should face the direction of the rear of the machine.
What is the correct pin angle setting for hollow pins?
It is important that the pin angle is set to 90° when using hollow pins. This minimizes pin movement in the soil, creating a ‘clean’ hole. Using an angle smaller than 90° can cause the pin to break.
What should be done if a lot of dirt is created when using hollow pins?
If a lot of dirt is created during pricking with hollow pins, reduce the PTO revolutions or sprinkle water. Dirt can cause wear & tear to your machine. If the lawn becomes damaged, use solid pins first to create healthy roots or adjust the working depth. If pins jam, the soil is very compressed; use solid pins first to break open the soil, then sprinkle water or adjust depth. If top dressing is needed, use the Verti-Drain first, remove cores, then scatter sand.
What is the purpose of the optional Windrow Kit?
If hollow pins are used, cores are removed from the substrate. The optional Windrow kit ensures that the cores are neatly guided together after the Verti-Drain operation, allowing for easy removal.
How can the machine be converted from mechanical to hydraulic depth adjustment?
The machine comes with standard mechanical depth adjustment but can be converted using an optional kit. The procedure is as follows (See fig. 19, refer to parts manual for specific parts):
- Position the Verti-drain on a firm underground and secure it against sinking away. Ensure the front roll can move freely and the machine isn’t leaning on it.
- Remove the covers (1).
- Turn the front roll (2) downwards so it just leans on the ground and the mechanical spindles (8) are free of tension.
- Remove the nuts (3).
- Remove the mechanical plates (4).
- Install the new plates (5, 6) included in the kit.
- Add bracket (7) on the left side and bolt everything together.
- Repeat steps 4 to 7 on the other side of the machine.
- Remove the left mechanical spindle (8) and its cylinder (9).
- Mount the correct hydraulic cylinder (10) (check shaft diameter – 25mm or 30mm depending on model/side) with included cylinders (11) and bolts (12) on the left side. Use existing bolts for attachment to the support (15).
- Remove the right mechanical spindle (8) and its cylinder (9).
- Mount the corresponding hydraulic cylinder (10) on the right side with included cylinders (11) and bolts (12). Use existing bolts for attachment to the support (15).
- Mount the hoses to the cylinders and other hydraulic components as indicated in the parts manual.
- Mount the covers (1) back onto the machine.
- Attach the hose blocks (13) and other hydraulic components to the covers (1).
- Mount the working depth indicator (14) onto the cover (1), feed the cable through the cover (1) and attach the end to the support (15). Use thread-locking sealant on the bolt to prevent loosening.
- Adjust the working depth indicator (14) so it registers the same depth as the indicators (16) on the sides of the machine.
- Check that all attachments are secure and attach the machine behind a tractor as described in chapter 3.0.
How is the hydraulic depth adjustment system vented after installation or maintenance?
Venting the hydraulic depth adjustment system:
- Connect the hydraulic hoses to the tractor.
- Lift the machine off the ground.
- Open the faucet (17) located on the right side of the machine by turning it to the left (using the included key).
- Activate the hydraulic outlet of the tractor and let the front roll move downwards carefully to remove the air from within the system.
- Close the faucet (17) by turning it to the right (use the included key).
What should be checked after venting the hydraulic system?
Ensure that both sides of the machine are moving up and down parallel to each other. If this is not the case, stop the movement immediately to prevent damage to the machine. Check connections and repeat venting if necessary.
