6. The PTO AXLE
The PTO is a very important component that takes care of the drive from the tractor to the machine.
The PTO axle ensures safe use of the machine on condition that it is properly installed and
maintained. The PTO has its own CE certification and manual. This manual is located near the PTO
axle.
See the details listed on the PTO page of the components booklet for specific adjustment values.
DO NOT exceed these values. This could result in an unsafe situation and could overload the
machine, resulting in damage to the machine.
Fig. 4
6.1. Length of the PTO axle
The length of the PTO axle is very important. If it is too long, it can damage the drive of the tractor
and/or the machine. If the overlapping length of the cylinders becomes less than 250 mm (9.8”) at any
time, it can damage the PTO axle. The required length changes when the machine is lifted or when a
different tractor is used! If a new machine is purchased or if another towing vehicle is used, the length
of the PTO axle should be checked and shortened, if necessary (see Fig. 4):
1. Measure the distance ‘A’ (from groove to groove) between the tractor’s PTO and the machine’s
connection point, when the machine is horizontal on the ground and the tractor is attached.

13
2. Measure the distance ‘B’ of the PTO axle in its shortest position from the locking pin to the
locking bolt.
3. Divide the PTO axle in two parts and remove the protection cap at both ends.
4. The ends of the cylinders and the protection caps should be shortened: (B-A) + 125 mm (4.9”).
5. Smooth off all components and then assemble all components. For this purpose, use lubrication
grease.
6. Mount the PTO axle including the slip coupling at the machine side.
7. Attach the other end of the PTO axle to the tractor.
8. Check the overlap of the cylinders.
Never use the machine if it has a damaged PTO protection cap.
First replace the protection cap.
If the PTO is shortened incorrectly or if another tractor is used, the gearbox may be
overloaded and cause damage.
6.2. Using the PTO axle
The following items must be checked for correct use of the PTO axle:
1. The angle of the rotation points should always be smaller or equal to 30 degrees during work
activities.
2. The PTO axle of the tractor must be parallel to the PTO axle of the machine.
3. The overlap of the cylinders must always be minimum 250 mm (9,8”).
4. Never use the machine if it has a damaged PTO protection cap.
5. See the PTO manual for information about lubrication.

14
7. ATTACHING AND DETACHING THE MACHINE
Attaching and detaching the machine has to be done carefully. Follow the instructions below:
Fig. 5
7.1. Attaching the machine

3. Attach the lifting arms (2) to the machine using the 3-point pins. Lock the pins using the clips.

15
4. Set the stabilizer of the lifting arms (2) to 100 mm lateral stroke.
5. Mount the top rod (3) on the tractor and attach it to the machine.
Set the top rod (3) in such a manner that in working position the machine is parallel to the
underground.
If the machine is incorrectly attached to the tractor, the different PTO angles can cause
vibrations in the driveline of the machine. These vibrations may damage the machine.
6. Attach the PTO (4) to the tractor (slip coupling at the machine side) and fold the bracket (5)
into the holder.
Make sure that the 3-point pins are locked using the clips !!
7. Start the tractor and lift the machine.
7.2. Detaching the machine
The machine should be detached in the following manner (see Fig. 5):
1. Drive to a spot where the machine should be detached.
Make sure that the parking place has a firm underground and that the machine cannot
sink.
Make sure that the machine and the tractor cannot move while you are detaching
them !!
Switch off the tractor engine before detaching the machine !!
2. Carefully place the machine on the ground.
Check again whether the machine is stable on the ground.
3. Loosen the top rod (3) and remove it.
4. Disconnect the lifting arms (2) from the machine.
5. Detach the PTO (4) at the tractor side and support it by using the bracket (5).
6. Start the tractor and drive off.

16
8. TRANSPORT
The user is responsible for transporting the machine on public roads. Verify the national legislation
regarding the regulations. In view of the machine’s weight, it is not advised to drive faster than 20 km/h
(12.4 mph) with a raised machine. Higher speeds can lead to hazardous situations and result in
damage to the machine and tractor.
When the machine is raised off the ground, the front axle of the tractor has to support
minimum 20% of its weight.
If the machine is not transported towed by the tractor, the machine may be secured/hoisted at the
following points (see Fig. 6):
1. Hoisting point for hoisting the machine
2. Securing points positioned at both sides of the machine
Fig. 6

9. PUTTING THE MACHINE INTO OPERATION
9.1. Safety
Before using the machine, you should check the following:
1. Are there loose objects in the field? First remove these objects.
2. Are there slopes? The maximum slope is 20 degrees for this machine. Always work from bottom
to top.
3. Are there cables/pipes buried in the ground? If so, determine their depth and adjust the working
depth of the machine to 60% of the depth of the cables/pipes.
4. Are there hard objects in the ground? If so, use the machine at an adjusted speed and adjust the
working depth.
5. Is there danger of situations that distract the attention of the driver? If so, the machine CANNOT
be used.
6. Is there danger of sinking/sliding away? If so, postpone the processing.
7. If the soil is frozen or very wet, postpone the activities until conditions improve.
8. Do NOT make sharp curves when the machine touches the ground.
9.2. Working speed
The maximum working speed depends on the soil conditions, working depth, gearbox settings and the
desired result.
The maximum working speed is limited to 6 km/h (3.75 mph) Higher speeds are not recommended
and might result in excessive wear & tear and damage to the machine.
If hard objects can be expected, the working speed should be reduced.
9.3. Start/Stop procedure
The start procedure is VERY important. If this procedure is not executed as described below, it might
result in serious damage to the machine.
The start procedure is as follows:
1. Check the machine for loose components and look whether all components function properly.
If loose components are observed or components do not function properly, the problems
must be solved before using the machines.
2. Drive to the spot where the processing should take place.
3. Lower the machine so that it is just slightly above the ground.
4. Set the tractor’s engine to approx. 1200 rpm.
5. Put the tractor in the correct gears and drive forwards.
6. Switch ON the PTO.
7. While it turns, lower the machine carefully into the ground during the forward drive.
8. Increase the PTO’s revolutions to the maximum allowed value of 540 rpm.
9. Treat a piece of land and assess whether the machine delivers the desired result.
Stopping occurs as follows:
1. Lower the PTO’s revolutions.
2. Detach the PTO and lift the machine off the ground.
3. Go to the next location and start again as described above.

10. TECHNICAL INFORMATION
Generally speaking, the Blecavator 145 / 210 is not a complicated machine. A number of technical
issues will be explained. If you still have questions, please contact your dealer who is always ready to
assist you.
10.1. Adjusting the working depth
The working depth can be adjusted by adjusting the rear roller as follows (see Fig. 7):
Fig. 7
!! Switch off the tractor’s engine before descending !!
!! Make sure that the tractor and the machine and PTO cannot move uncontrolled !!
1. Loosen the nuts (1) of the spindles (2) on both sides of the machine one whole turn.
2. Turn the roller to the required working depth using the spindles (2) on both sides of the
machine.
3. Tighten the nuts (1) of the spindles (2).

19
10.2. Putting the rear roller off centre
If required, the rear roller can be put off centre. You can slide the roller to the left or to the right so that
you overlap the part that is already treated.
Adjusting is done as follows (see Fig. 8):
Fig. 8
!! Switch off the tractor’s engine and PTO before descending !!
!! Make sure that the tractor and the machine cannot move uncontrolled !!
1. Loosen the two nuts (1) and the two bolts (2) a few turns.
2. Slide the roller to the required position by lifting the rear roller slightly using the two handgrips
(3).
3. Tighten the bolts (2) and nuts (1).
10.3. Adjusting the levelling bar
The levelling bar is used to obtain a nice looking, flat surface after treatment.
The levelling bar should be set to the required height, which depends on the conditions and
composition of the ground.
In general, a nice looking, even end-result is created if a small quantity of soil remains in front of the
bar during treatment.

20
Adjusting is done as follows (see Fig. 9):
Fig. 9
!! Switch off the tractor’s engine and PTO before descending !!
!! Make sure that the tractor and the machine cannot move uncontrolled !!
1. Turn the spindles (1) on both sides of the machine until the correct position has been reached.
Attention: Both sides of the machine should be positioned at the same depth.
