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) + 75 mm (3”).
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.
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 150 mm.
4. Never use the machine if it has a damaged PTO protection cap.
5. See the PTO manual for information about lubrication.
6.3 Slip coupling: Information and maintenance
If used and maintained correctly, the slip coupling will protect your machine against damage. The
following data are important for adjusting the slip coupling (see Figure 4).
Figure 4
1. The depressed length H of the cup spring is standard set at 15 mm (0.59”) (550 Nm (4,868
lbf.inch)).
2. When the slip coupling slips, the bolts and nuts may be tightened gradually, until the minimum
length of 14.4 mm (0.57”) of the cup spring is achieved (700 Nm (6,195 lbf.inch)). Additional
compression will overload the machine.
Screwing the bolts / nuts too tight could ultimately damage the machine or create
unsafe situations.
!! If the slip coupling starts to operate, you should switch off the PTO, lift the machine
off the ground, and repeat the start procedure.
