TECHNICAL DATA

GENERAL DESCRIPTION

The Verti-Drain® is a machine for aerating fields of grass and sports fields. The Verti-Drain® is a three-point machine which requires a tractor or Verti-Power in order to utilize the Verti-Drain®.

FIRST INSTALLATION, REMOVING THE MACHINE FROM THE PALLET

The machine is positioned vertically on the pallet. To remove the pallet and position the machine horizontally on the floor, act as follows (see fig. 8):

1. Remove the PTO, PTO protective covers and tines from the machine.
2. Disassemble the support legs (1) and position them so the Verti-Drain® can be placed on the legs.
3. Attach a cable underneath the top link strips (2) so the machine can be lifted.
4. Ensure that the cable/crane/hoist has a minimal load lifting capacity of 2000 kg (4410 lbs).
5. Lift the machine together with the pallet 50 mm (2") off the ground.
6. Do not crawl underneath the machine! ⚠️
7. Remove the pallet (3).
8. Slowly lower the machine until the support legs (1) touch the ground.
9. Slowly continue to lower the machine so it is positioned on all four support legs.
10. Assemble the added PTO-Cover 2.
11. Couple the machine to a tractor.
12. Use a suitable tractor; see specifications.
13. Lift the machine off the ground.
14. Reassemble the support legs (1) up into transportation position or remove them.
15. Place the machine with the frontroller on the ground at the required working depth and adjust the angle of the machine to 90 degrees by turning the top link (4). This 90 degree angle is very important for the correct operation of the machine.
16. Set the stabilizer of the tractor to 100 mm lateral movement.
17. Assemble the tines. Use a little grease on the post.
18. Determine the length of the PTO (5) and assemble it, see chapter 4.1.
19. When machine is taken of the pallet, remove the upper plug of the gearbox and replace it with the supplied breather.

THE PTO

The PTO is a very important component. It provides the transmission from the tractor and, if correctly maintained and installed, will ensure a safe utilisation of the machine. The PTO has its own CE certification. Read the PTO manual; it is located on the PTO itself.

LENGTH OF THE PTO

The length of the PTO is very important. When it is too long, the transmission of the tractor and /or the Verti-Drain® can become damaged. When, at any given moment, the overlapping length of the tubes becomes less than 150 mm (6") the PTO can become damaged.

? The length changes when the machine is lifted or when a different tractor is used.

To bring the PTO to the correct length, whenever a new one is acquired or when using a different tractor, work as follows: (see Fig.9)

1. Measure the distance between the PTO connection of the tractor and that of the Verti-Drain®, from groove to groove, when the machine is positioned at the right angle on the ground and is coupled to the tractor.
2. Measure distance B of the PTO in its shortest position from the locking pin to the locking bolt.
3. Split the PTO in two parts and remove the protective cover on both ends.
4. Both the ends of the tubes and the protective covers have to be shortened: (B-A) + 75 mm (3").
5. Remove the edge trims from all components, apply some grease and assemble all parts.
6. Install the PTO on the Verti-Drain® side.
7. Couple the other end of the PTO to the tractor.
8. Check the overlap of the tubes.

Never use the machine with a damaged PTO protective cover. Replace it first.

USING THE PTO

In order to correctly use the PTO, the following items need to be checked first:

1. During operation, the angle of the pivot points must never exceed 30 degrees.
2. The pivot points must always be in line.
3. The overlap of the tubes must always be at least 150 mm.
4. Never use the machine with a damaged PTO safety cover.
5. For lubrication, see par. 13.0: Maintenance.

WORKING DEPTH ADJUSTMENT

The working depth can be adjusted if the machine is raised (before start of operation) or during processing of the ground when the machine is operating.

To adjust working depth (see fig. 10):

1. First turn the nuts (1) of the front roll loose one turn.
2. Adjust the roll to the desired working depth by turning the spindle nuts (2).
3. Retighten the nuts (1) of the front roll again.

The working depth adjustment on the stickers is only applicable when tines with a length of 150 mm (6") are being used. When shorter tines are used, subtract the length difference with regard to the 150 mm (6") from the value on the stickers.

TINE (INSERTION) ANGLE ADJUSTMENT

All tines can be adjusted at the same time in order to increase or decrease the tine angle. To adjust the tine angle (see fig. 10):

1. Loosen the nuts (3) of the corner adjustment one turn.
2. Use the handle (4) to position the pins in the desired tine angle.
3. Retighten the nuts (3) of the corner adjustment again.

A 90 degree angle means hardly any insertion. This is required for hollow tines and is advised for the 8 mm (5/16") tines.

From 90 to 70 degrees means increased insertion. This is advised for solid tines and depends on the soil condition, the tine size and the customer's wishes.

At 90 degrees the tines only go dead straight into the ground if the machine is correctly installed, see fig. 8. If this is not done correctly a force F, see fig. 10, may result, which damages the machine.

The length of the compound connecting rod (5) must be 365 mm (14.4”), which can be calibrated by using shims (6).

DRIVING SPEED

The pitch in the driving direction depends on the driving speed. When a small pitch is desired, the driving speed must be sufficiently low, which depends on the tractor or the Verti-Power.

The rpm input of the PTO may not exceed 540 rpm.

⚠️ If hard objects are expected, this speed must be lowered.

With heavier tines, other applications or with the maximum tine angle, the tine holders may start floating. Lower the rpm as well in that case, before the tine holders slam upwards.

If the Verti-Drain® is not correctly mounted behind the tractor, see fig.8, different PTO angles can cause vibrations in the messenger bar of the machine. These vibrations can damage both the machine and the holes in the ground.

If the PTO is shortened incorrectly, or when another tractor is used, the gear casing can be overloaded, resulting in damage.

START/STOP PROCEDURE

The start procedure is VERY important. If this procedure is not executed as described below, serious damage to the machine can result. The start procedure is as follows, see fig. 11.

1. Drive to the location where operations will take place.
2. Lower the machine, until the lowest tines almost touch the ground.
3. Switch the tractor engine to a low rpm.
4. Switch the tractor into the correct gear and drive forward carefully (A).
5. Engage the PTO (B).
6. Lower the machine DURING driving forward, CAREFULLY TURNING into the ground (C).
7. Raise the PTO rpm to the maximum allowed value.

Stopping is done as follows:

1. Lower the engine rpm.
2. Lift the machine out of the soil.
3. Decouple the PTO, as soon as the tines are out of the soil.
4. Raise the machine up further, until the tines are at least 120 mm free from the soil.
5. Go to the next location and start again as described.

It is absolutely essential to proceed according to the procedures described above. If the machine is first lowered into the ground, without a revolving PTO, serious damage could be done to the machine.

One needs to lower the machine CAREFULLY.

Be careful when reversing.

During the proceedings, the front roller should be stable while resting on the ground. If the machine becomes unstable, the other tines need to be disassembled, or the working depth needs to be adjusted.

The machine will become damaged if the instability is not fixed. The machine is NOT protected against this kind of continuous overload.

Do NOT EVER reverse with the tines in or close to the soil.

Do not use a hydraulic top bar.

USING THE VERTI-DRAIN®

Before the Verti-Drain® is used at a location, the following needs to be checked:

1. Are there any loose objects present in the field? Remove them first.
2. Are there slopes? The maximum inclination allowed to work on with this machine is 20 degrees. Always work from top to bottom.
3. Are there cables/pipes located in the ground? If so, determine the depth of these and adjust the working depth of the machine to 60% of this depth.
4. Are there any hard objects in the ground? If so, use the Verti-Drain® at a low PTO speed and adjust the working depth.
5. Is there any danger of airborne objects like golf balls, which might divert the attention of the driver? If so, the Verti-Drain® should NOT be used.
6. Is there any danger of sagging, sliding? If so, postpone using the Verti-Drain®.
7. If the soil is frozen or very wet, postpone any activities until the conditions have improved.
8. If the ground is very compacted, use shorter tines or adjust the working depth.

TRANSPORTING THE VERTI-DRAIN®

The user is responsible for the transportation of the Verti-Drain® behind the tractor via public roads. Please check the national legislation with regard to applicable regulations. Due to the weight of the Verti-Drain®, a maximum speed of 12 km/hr (8 mph) may be driven on open fields. A higher speed may be dangerous to the driver/bystanders and could even damage the machine.

For transportation in combination with the Carrier, see the manual of the Carrier.

When the machine is lifted off the ground, at least 20% of the weight of the tractor should be resting on the front axle.

UNCOUPLING THE VERTI-DRAIN®

To uncouple the Verti-Drain® from the tractor, use the following procedure:

1. Open the rear cover.
2. Turn the crankshaft until all tine holders are in the highest position possible.
3. Assemble legs so the Verti-Drain® will rest on the legs when the machine is lowered further (see fig. 12).
4. Next place the machine, in the highest position, on a stable surface.
5. Remove the top bar.
6. Undo the PTO at the tractor's end.
7. Remove the support brackets of the tractor from the Verti-Drain®.

Turn off the tractor engine when walking around the machine and block the tractor from moving! ⚙️

? When storing the machine for a longer period of time, it is advisable NOT to fold up the tines for the sake of the durability of the shock absorber springs.

PROBLEM ANALYSIS

MAINTENANCE

TECHNICAL INFORMATION

Generally speaking, the Verti-Drain® is not a complicated machine. A few technical items will be explained. If you still have additional questions, please get in touch with your dealer, who will be pleased to help you.

THE CRANKSHAFT

In figure 13, the composition of the PTO is shown. Also see the components page for a more detailed drawing.

REPLACING A CRANK/CRANK BEARING

Replacing a crank bearing is necessary when it is fractured or when the nuts of the big-end regularly become loose. The crank bearings, the crank bearing fittings or the big-end pin holes in the crank are damaged. Replace the crank / the bearing as soon as possible in order to avoid any further damage to other parts, as follows (see fig 13):

1. Remove the bolts and nuts (7 & 8) of the actuating rod's connecting strips (9).
2. Remove one or both of the actuating rod's connecting strips (9).
3. Remove the big-end nut (11) and big-end pen (10).
4. Remove the big-end (4).
5. Remove the bolts and nuts (5 & 6) and closing plates (1).
6. Take out the crank (3).
7. Remove the bearing (2).
8. Replace the defective parts and reassemble in reverse order.

Use Loctite for nuts 1 and 3.

RELIEVING CRANKSHAFT TENSION

When components of the crankshaft have been replaced, the crankshaft might run with more resistance. The cause could be pretension. It is necessary to remedy this tension as follows:

1. Check which big-end runs with more resistance and causes tension.
2. Use a hammer to hit the cranks in question, next to the big-end causing tension, in order to remove the tension.
3. Check each big-end of the crankshaft for tension until the tension is removed from all the elements.

In order to prevent damage to the crankshaft, do not use the machine before all the tension is removed from the crankshaft.

After repair of the crankshaft, nuts should be regularly checked for looseness.

Mount the cranks in the correct manner; see the parts page for the correct sequence and parts numbers.

TIMING AND TIGHTENING TORQUE

In fig. 14, the tightening torque of the most important bolts/nuts are displayed. Assure yourself that the bolts and nuts, for which these settings are not displayed, are tightened exactly the same as similar bolts and nuts. When bolts and nuts become loose, you may use Loctite to tighten them again.

The timing of the crankshaft is determined by the mutual angle of 120°(VD1513) 90°(VD1517) (see fig. 14). Because the timing of the machine is symmetrical, only four different cranks are used. The centre crank divides the machine in two halves as it were, in which each of the two halves has its own type of cranking element. The crankshaft at the end has the same end crank. See page six of the parts book to mount the crankshaft in the correct manner. This way, the timing of the crankshaft will always be correct.

TENSION THE V-BELTS

!! Make sure that the Verti-Drain is properly blocked and can not move of its own accord !!

!! Make sure that the PTO shaft is disconnected from the Verti-Drain !!

To tension the V-belts on both sides of the machine, proceed as follows, see fig 14-2.

1. Remove all nuts (1) and the safety cover (2).
2. Check the V-belt tension by pressing point 'A' with a tension of 3.5Kg (7.7lbs). The impression should be 1.9mm (0.07) (per belt).
3. If the tension is correct replace safety cover (2) and replace nuts (1).
4. If the tension is not correct loosen the nut (3) a little bit so that the tension is just off.
5. Adjust nu and counter nut (4) and adjust the tension of the V-belts.
6. Check the V-belt tension by pressing point 'A' with a tension of 3.5Kg (7.7lbs). The impression should be 1.9mm (0.07) (per belt).
7. Tighten nut and counter nut (4).
8. Tighten nut (3).
9. Replace safety cover (2) and replace nuts (1).

OPTIONS, TURF HOLD DOWN KIT

You can use a turf hold down kit whenever the turf is loosened.

There is 1 turf hold Down Kit available:

• For the 12 mm (1/2") tines under number : VD1513: 211.215.000 VD1517: 211.215.012

By default, the Verti-Drain® 1513/1517 already has a pre-mounted principle beam to which the turf hold down fingers can be attached.

The kit consists of a set turf hold down fingers for 12 mm (1/2") and the assembly material, consisting of several bolts and nuts.

MOUNTING THE TURF HOLD DOWN KIT (see fig. 15):

Plates (1) are enclosed with the ordered set. Mount the plates with bolt (2), rings (3 & 4) and nut (5) to the principle beam. Align the plates with the tines via the slotted openings in the plates.

When, after having been used for a while, the plates are bent in one direction, assemble them the other way around.

OTHER REMARKS:

When the tines are no longer centred in the machine, they could hit the sides of the slots. Align the tine blocks again.

Check the length of the actuating rod whenever the tines hit the front of the hole (during operation).

Never crawl underneath the machine. Make sure that the machine is securely blocked! ⚠️

OPTIONS, TINES

Tines are essential for the correct functioning of the machine. There are several different tines available for this machine, see the parts pages for a complete overview. Generally speaking, the tines can be divided into two categories: solid and hollow tines. We advise to only use original tines, because they are completely adapted to the machine.

There is a tine holder available for each different tine type (see parts page 7 for parts numbers).

The locking bolt A can be tightened to 40 Nm (29, 5 lbf.ft.). (Fig.16)

The locking bolt B can be tightened to 150 Nm (110, 5 lbf.ft.). (Fig.16)

The locking bolt C can be tightened to 10 Nm (7, 5 lbf.ft.). (Fig.16)

When the tines become detached from the tine holder, grind part of the mounting side of the tine flat.

SOLID TINES

Solid tines break open the hard compaction of the ground. The tine angle adjustment (see Chap. 6.0) determines the amount of tine angle movement in the ground. If the angle is readjusted from 90 to 70 degrees, the tine angle movement increases. With a 90 degree adjustment, hardly any tine movement will be created in the ground.

When the tines are new they can damage the turf, especially with a weak root system. First clean the tines manually or use the machine first for 10 minutes on different, rough surface.

When the root system is weak, adjust the working depth in such a manner that the poking depth is slightly deeper than the length of the roots. This offers the roots the chance to grow deeper. Poke deeper again next time. By using this method you can prevent damage to the turf and will ensure a healthy root system.

We advise you to use the solid tines with the sharp point directed towards the front roller. In this manner you ensure the best tine movement in the soil. However, in case of weak turf it is advisable to use the tines with the sharp point directed towards the backside of the machine.

Always use tines with similar diameter and length. Replace a bent tine immediately. If this doesn't happen, the machine can become unstable. Do not use thicker and/or longer tines than supplied by us.

Shorter (worn down) tines can be used when superficial poking is desired. Make sure that the working depth indicated on the sticker is only correct when the maximum length of the tine is used.

When oval holes are created, it means that there is a weaker top layer and a hard layer beneath it. Use thinner tines or wait until the (wet) top layer has dried.

When a top dressing has to be applied, then apply this first before using the Verti-Drain®.

If the ground is hard to poke irrigate it first, use thinner and shorter tines, or adjust the working depth. If this does not happen the machine will eventually become damaged.

HOLLOW TINES

Hollow tines can be used to mix the soil. There are several sizes available, see the parts page. The opening of the tine must be point towards the back of the machine, unless the opening is located at the top of the tine. In that case the direction of the tine does not matter.

With hollow tines it is important that the tine angle is set at 90 degrees. The movement of the tine in the soil is minimal and in this manner a nice “clean” hole is produced. When the tine continues to move with an angle setting of less than 90 degrees, the tine could eventually break.

If a lot of dirt is produced during the poking with the hollow tines, lower the rpm or irrigate first. The dirt could speed up the wear and tear of your machine.

When the turf is damaged, first use solid tines to generate a healthy root system, or adjust the working depth.

When hollow tines get blocked, it means the soil is (very) compact and solid tines need to be used first to break open the soil. Irrigating or adjusting the working depth could also be helpful in this situation.

MULTI-TINE BLOCKS

It is possible to use tines with a small diameter, also called needle tines (Ø8), for the Verti-Drain®. They are mounted in multi-tine blocks, after which the whole set-up is mounted on the tine holder. See the parts book for options.

OPTIONS, BACK ROLLER

The kit consists of a back roller with adjustable scraper and the support brackets with mounting material for coupling with the Verti-Drain®.

OPTIONS, WINDROW KIT

When the poking is done with hollow tines, cores are removed from the underground. The Windrow kit ensures that, after the Verti-Drain® process, the cores are neatly placed together and afterwards can be easily removed.
