4.0 The PTO shaft
The PTO shaft is a very important part. It provides the driving force from the tractor and – if
installed, used, and maintained correctly – ensures safe use of the machine. The PTO shaft
has its own CE certificate. Make sure to read the PTO shaft manual. It is located on the PTO
shaft itself.

Fig. 10
4.1 LENGTH OF THE PTO SHAFT
The length of the PTO shaft is very important. If it is too long, it may damage the drive of the
tractor and/or the Verti-Drain
®
. If the overlapping length of the sleeves is, at any time, shorter
than 150 mm, the PTO shaft may be damaged.
*The length will vary when the machine is raised or if another
tractor is used.
To make sure the length of the PTO shaft is correct, after purchase or when using another
tractor, carry out the following steps: (see Fig.10)
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 at the correct angle on the ground
and attached to the tractor.
2. Measure the distance B of the PTO at its shortest position, from locking pin to locking
bolt.
3. Split the PTO in two and remove the protective cover from both ends.
4. Both the sleeve ends and the cover ends have to be shortened: (B-A) + 75 mm (3”).
5. Debur, grease, and assemble all parts.
6. Mount the PTO on the Verti-Drain side.
7. Attach the other end of the PTO to the tractor.
8. Check the overlap of the sleeves.
*Never use the machine if the protective cover of the PTO is damaged.
Replace it first.

12
4.2 OPERATION OF THE PTO SHAFT
To ensure correct operation of the PTO, check the following items:
1. During operation, the angle of the joints must never be greater than 30 degrees.
2. The rotating points should be aligned.
3. The overlap of the sleeves must be at least 150 mm.
4. Never use the machine if the protective cover of the PTO is damaged.
5. For lubrication, see section 13.0: Maintenance.

5.0 OPERATING-DEPTH ADJUSTMENT
The operating depth can be adjusted when the machine is lifted, see fig. 11.
Loosen nuts 1 one turn on both sides of the machine.
Then turn bolt 3 in or out. Each rotation is 4 mm (0.160”). Label 2 on the side of the machine
indicates the depth setting. After having reached the correct working depth, retighten nuts 1.
@ Never adjust one side more than 4 turns. Before continuing, compensate the other
side.
@ A spanner is included in the machine’s tool tube.
@ The depth-adjustment on the decals only applies when 150 mm (6”) long pins are
used. When shorter pins are used, subtract the difference in length, compared to 150
mm (6”), from the value shown on the decals.
@ The spindle and the nut must be cleaned every 100 hours and sprayed with thin oil
that does not attract dirt, to prevent dirt from remaining on the nut.

13
6.0 PIN ANGLE ADJUSTMENT
All pins can be simultaneously adjusted with a centrally-placed handle, located on the side of
the machine, see fig. 12. Lift the machine above the ground and loosen nut 2 on both sides
of the machine. Adjust the angle by turning the handle. The angle can be read on the sticker.
Retighten the nuts.
@ An angle of 90 degrees means almost no draught. This is required for hollow pins
and is advised for the needle pins.
@ From 90 to 75 degrees means more draught. This is advised for solid pins and
depends on the ground conditions, the pin size and the client’s preference.
@ At 90 degrees, the pins only go straight into the ground if the machine is correctly
installed, see fig. 1. If this is not correct, force F can be produced, see fig. 12, which
will damage the machine.
@ The length of the assembled drawbar must be 291 mm (11.5”), which can be
calibrated using shims, see parts page.
7.0 DRIVING SPEED
The hole distance D, fig. 13, in the driving direction is determined by the drive speed. The
Verti-Drain
®
does not require creep gear. If the client wants a small hole distance, however,
it must be possible to ride slowly enough, which depends on the tractor.
The input speed of the PTO shaft R may not exceed 500 rpm. If hard objects can be
expected, this speed must be reduced.
With heavier pins, other applications, or with maximum pin angle, the pin holders may float.
In this case, reduce the speed R before the pin holders are forced upward.
Fig. 13 contains a table that shows the relationship between the driving speed and the hole
distance. If the driving speed of the tractor for 500 revolutions of the PTO shaft is known, the
hole distance can be determined.
@ If the Verti-Drain
®
is not correctly attached behind the tractor, see fig. 8, various PTO
shaft angles can cause vibrations in the driveline of the machine. These vibrations can
damage the machine and the holes in the ground.
@ If the PTO shaft was shortened incorrectly, or if another tractor was used, the gearbox
may be overloaded. Damage can occur.

8.0 START PROCEDURE
The start procedure is VERY important. If this procedure is not followed exactly as described
below, serious damage may occur to the machine. The start procedure is as follows, see fig.
14.
1. Drive to the place where you want to start.
2. Lower the machine until the lowest knives are almost touching the ground.
3. Set the tractor motor at approximately 1200 rpm.
4. Shift the tractor to the correct gear and drive forward (A).
5. Engage the PTO shaft (B).
6. While DRIVING forward, let the TURNING machine CAREFULLY sink into the
ground (C).7. Increase the PTO shaft speed to the maximum allowable speed.
Stopping is done as follows:
1. Decrease the motor speed to approximately 1200 rpm. Raise the
machine out of the ground
3. Disengage the PTO shaft as soon as the pins are out of the ground.
4. Raise the machine further until the pins are at least 120 mm above the ground.
5. Go to the following place and start again as described.
@ It is absolutely imperative that the above procedures are followed. If the machine is
placed in the ground first, without a rotating PTO shaft, serious damage to the
machine can occur.
@ The machine must be lowered CAREFULLY.
@ Be careful when driving in reverse.
While working, the front roller must be in stable contact with the ground. If the machine is
unstable, other pins must be installed or the operating depth must be adjusted.
@ The machine will be damaged if the instability is not corrected. The machine does
NOT have protection against long-duration overloading.
@ NEVER drive in reverse with the pins in, or close to, the ground.
@ Do not use a hydraulic top rod.
`
9.0 OPERATION OF THE VERTI-DRAIN
®
Before the Verti-Drain® is used in the field, the following should be checked:
1. Are there any loose objects in the field? Remove these first.
2. Are there any slopes? The maximum slope this machine can work on is 20 degrees.
Always work downhill.
3. Does the ground contain cables or pipes? If so, determine their depth and set the
operating depth of the machine to 60% of this depth.
4. Does the ground contain hard objects? If so, use the Verti-Drain
®
at a low PTO shaft
speed and adjust the operating depth.
5. Is there any danger of flying objects, such as golf balls, which may distract the attention
of the driver? If so, do NOT use the Verti-Drain
®
.
6. Is there any danger of sinking or sliding away? If so, postpone working with the Verti-
Drain
®
.
7. If the soil is frozen or very wet, the work should be postponed until the conditions are
more favourable.
8. When the soil is very compact, use shorter pins or adjust the operating depth.

16
10.0 TRANSPORT OF THE VERTI-DRAIN
®
The user is responsible for the transport of the Verti-Drain
®
behind the tractor when travelling
on public roads. Check the national traffic regulations. On open fields, a maximum speed of
12 km/h (8 mph) should be observed, because of the weight of the Verti-Drain®. A higher
speed may endanger the driver and/or other people and may even damage the machine.
* When the machine is in the raised position, at least 20% of the weight of the
tractor should be supported by the front axle.

Fig. 15
11.0 DISCONNECTING THE VERTI-DRAIN
®
The machine can be disconnected from the tractor as follows:
(see fig. 15)
1. * Check the ground where the machine is to be disconnected; this must be firm and flat.
The machine may not be able to sink/move on its own.
2. Turn adjustable legs 1 downwards and block them with the R-clips.
3. Carefully lower the machine onto the adjustable legs.
4. Lock the machine to prevent it from moving.
5. Remove the top rod.
6. Remove the PTO shaft on the tractor side.
7. Remove the lower arms from the Verti-Drain
