6. THE PTO SHAFT
The PTO shaft is a very important part. It provides the drive from the tractor to the machine. The PTO
shaft, when properly maintained and installed, ensures safe operation of the machine. The PTO shaft
has its own CE certification and manual. These are found with the PTO shaft.
For specific adjustments, see the details given on the PTO page in the parts manual.
Do not exceed the specified values. Failure to heed this instruction may lead to an unsafe situation
and overload the machine, resulting in damage.
Fig. 4
Fig. 5
6.1. Length of the PTO shaft
The length of the PTO shaft is very important. If it is too long, the tractor’s drive system and/or the
machine may be damaged. If the overlapping length of the yokes is reduced to less than 250 mm
(9.8") at any time, the PTO shaft may be damaged. The required length changes when the machine is
lifted or when a different towing vehicle is used. When the machine is purchased new, or when using a
different towing vehicle, the length of the PTO shaft must be checked and shortened if necessary:
1. Measure distance ‘A’ (from groove to groove) between the tractor’s PTO and the machine’s
connection while the machine is standing horizontal on its support legs on the ground and is
connected to the tractor.
2. Measure distance ‘B’ of the PTO shaft in its shortest position, from locking pin to locking bolt.
3. Split the PTO shaft in two and remove the safety shield from both ends.

12
4. Both the ends of the yokes and the halves of the safety shield must be shortened: (B-A) + 125 mm
(4.9”).
5. Deburr all the parts and reassemble. Apply grease during assembly.
6. Fit the PTO shaft with the slip clutch on the machine end.
7. Connect the other end of the PTO shaft to the tractor.
8. Check the overlap of the yokes.
Never use the machine with a damaged PTO safety shield.
Replace it first.
6.2. Use of the PTO shaft
For correct use of the PTO shaft, the following items must be checked:
1. During the work, the angle of the pivot points must never exceed 30 degrees.
2. The tractor’s PTO shaft must be parallel to the machine’s PTO shaft.
3. The yokes must always overlap by at least 250 mm (9.8").
4. Never use the machine with a damaged PTO safety shield.
5. For lubrication, see the PTO manual.
7. CONNECTING AND DISCONNECTING THE MACHINE
Proceed with care when connecting and disconnecting the machine. Follow the instructions below:

4. Set the stabiliser for the lift arms (2) to 100 mm lateral play.
5. Fit the top link (4) to the tractor and connect it to the machine.
Use the round top link holes only for flat fields and the slotted hole for rolling fields.
6. Adjust the top link (4) so that the machine is parallel to the ground in the operating position.
If the machine is not correctly mounted behind the tractor, some angles of the PTO
shaft may cause vibrations in the machine's driveline. These vibrations may damage
the machine.
7. Connect the PTO (3) to the tractor (slip clutch at machine end) and flip the bracket (5) in the
holder.
Make sure the three-point hitch pins are secured with the lynch pins!!
8. Start the tractor and lift the machine.

14
7.2. Disconnecting the machine
The machine must be disconnected as follows: (Fig. 7)
1. Drive to the location where you want to disconnect the machine.

2. Lower the support legs.
Make sure the storage area has a stable surface and that the machine cannot sink in.
Make sure the machine and tractor cannot move during the disconnection process!!!
Shut off the tractor’s engine before disconnecting the machine!!
3. Carefully place the machine on the ground.
Check again that the machine is standing stably on the ground.
4. Disconnect the top link (4) and remove it.
5. Disconnect the link arms (2) from the machine.
6. Disconnect the PTO (3) at the tractor end and support it with the bracket (5).
7. Start the tractor and drive it away.
8. TRANSPORT
The user is responsible for the transport of the machine on public roads. Check national legislation for
applicable regulations. Given the weight of the machine, it is not recommended to drive faster than 20
km/h (12.4 mph) with a lifted machine. Higher speeds can lead to dangerous situations and damage to
machine and tractor.
When the machine is raised off the ground, at least 20% of the tractor's weight must
remain on the front axle.
When not transported behind the tractor, the machine may be secured/lifted
at the following points: (Fig. 8)
1: Lift point for lifting the machine.
2: Lashing points (4x) on the machine.
3: Support for the front half of the PTO shaft.
4: Front half of the PTO shaft.

Fig. 8
9. PUTTING THE MACHINE INTO OPERATION
9.1. Safety
Check the following before using the machine:
1. Are there loose objects in the field? Remove them first.
2. Are there inclines? The maximum incline on which work may be performed with this machine is 20
degrees. Always work from bottom to top.
3. Are there cables/pipes in the ground? If so, determine their depth and set the working depth of the
machine to 60% of this depth.
4. Are there hard objects in the ground? If so, use the machine at an appropriate speed and adjust
the working depth.
5. Is there any danger of situations that may distract the driver's attention? If so, the machine may
NOT be used.
6. Is there a danger of sinking or slipping? If so, postpone the operations.
7. If the soil is frozen or very wet, postpone the work until conditions improve.
8. Do not make any turns during the operations.

16
9.2. Working speed
The maximum working speed of the machine depends on soil conditions, working depth, gearbox
settings and the desired result.
The maximum working speed is limited to 3 km/h (1.9 mph). Faster speeds are not recommended due
to excessive wear and potential damage to the machine.
If hard objects are to be expected, the working speed must be reduced.
9.3. Start/Stop procedure
The start procedure is VERY important. Failure to carry out this procedure as described below may
result in severe damage to the machine.
The start procedure is as follows:
1. Check the machine carefully for loose parts, and make sure all parts are working properly.
If loose parts are found or parts do not work properly, the problems must be
corrected before the machine is used.
2. Drive to the location where the operations are to be performed.
3. Check that the set working depth is correct.
4. Lower the machine to just above the ground.
5. Set the tractor engine speed to approximately 1200 rpm.
6. Engage the PTO.
7. Increase the PTO speed to the maximum allowable value of 540 rpm.
8. At a standstill, while the machine is rotating, carefully lower it into the ground.
9. Select the proper gear in the tractor and start driving forward slowly.
10. Work a section of ground and assess whether the machine's settings are producing the desired
result.
Stopping is done as follows:
1. Bring the tractor to a standstill.
2. Reduce the PTO speed.
3. Disengage the PTO and raise the machine out of the ground.
Only raise the machine out of the ground in an area that is flat side to side, to prevent the
machine from swinging and scalping the turf.
4. Go to the next location and start again as described.

17
10. TECHNICAL INFORMATION
Generally speaking, the Multivator is not a complicated machine. A number of technical matters will be
explained. If you still have questions thereafter, contact your dealer, who will be happy to assist you.
10.1. Adjusting the working depth of the rotor
The working depth can be adjusted by adjusting the support rollers, as follows:
(Fig. )
Fig. 9
!! Shut off the tractor’s engine and disengage the PTO before stepping out!!
!! Make sure the tractor and machine cannot move unintentionally!!
1. Use the spindles (1 and 2) (both sides of the machine) to set the roller to the desired working
depth.
2. Use the indicators (1 and 2) on both sides of the machine to adjust the machine equally on
both sides.
Use the round top link holes only for flat fields and the slotted hole for rolling fields.
On flat fields, use only the front roller for working depth and raise the rear roller a few
centimetres above the ground for a looser soil layer after the operations.

18
10.2. Adjusting the working depth of the blade roller
The cutting roller depth can be adjusted independently of the rotor, but the cutting roller depth
depends on how the support rollers are set. If these are adjusted, the cutting roller depth will change
too.
!! Shut off the tractor’s engine and disengage the PTO before stepping out!!
!! Make sure the tractor and machine cannot move unintentionally!!
First loosen the nuts (4) of the spindles (3) (fig. 10) one turn (both sides of the machine).
2. Use the spindles (3) (both sides of the machine) to set the roller to the desired working depth.
The maximum adjustment is 10 cm (4") difference between the two sides!!
3. Use the indicators (5) on both sides of the machine to adjust the machine equally
on both sides.
4. Tighten the nuts (4) of the spindles again.
Initially, set the depth of cut shallow in wet and hard
soils and assess the operation after a few metres.
If the ground is wet, check for damage to the turf as a
result of adhesion to the blades.
In hard soil, check whether the working depth of the blade
roller affects the working depth of the rotor.
Fig. 10

19
10.3. Opening machine access hatches
The Multivator is fitted with access hatches for access to the inside of the machine, for cleaning and
replacing blades, etc.
These hatches must be opened as shown below (fig. 11):
!! Shut off the tractor’s engine and disengage the PTO before stepping out!!
!! Make sure the tractor and machine cannot move unintentionally!!
1. Use a tool to loosen all the bolts (1) of the hatches one turn.
2. Then loosen them the rest of the way by hand, alternating back and forth between them.
The bolts are fitted with retainer rings to prevent them from falling out of the hatches.
3. Open the hatches; the gas struts (2) will hold them open while you perform the necessary tasks.
4. Wipe away any dirt from the various surfaces before closing the hatches again.
5. Tighten the bolts (1) of the hatches again in the reverse order.
Fig. 11

11. OPTIONS
The following options are available for the Multivator:
11.1. Hydraulic rear brush
A hydraulic rear roller is available for aerating the loosened soil for faster drying.
Part number: 215,180,002
The set includes all necessary materials. See parts manual for the contents.
The rear brush is hydraulically driven and hydraulically liftable and is mounted on the inside of the rear
roller for depth adjustment.
The brush height is adjusted in the same way as the working depth of the base machine.
During transport, the brush must always be raised, i.e. with the lift cylinder retracted.
Fig. 12
