7.2
Fitting the drive train
Before installing the universal shaft, check that the direction of rotation and the speed of the universal shaft
correspond to those of the tractor. In addition, carefully read the power take-off stub and tractor manufacturers'
operating instructions. Before going ahead with commissioning, please make absolutely sure that all safety shields
are fitted in the correct location. In particular, check that the safety guard completely covers the PTO stub. When
connecting the mower unit's universal shaft to the tractor PTO stub, make sure that the universal shaft locks
securely into the groove on the tractor PTO stub shaft. A drive train not properly connected to the tractor's PTO stub
could loosen and endanger people, as well as damaging the machine.
CAUTION
Make absolutely sure that the two parts of the universal shaft cannot separate from each other with the three-point
hydraulics in any position. When the universal shaft is fully pushed together, there should be at least 20 mm
clearance between each profiled end and the opposing profiled universal joint. For safe operation, both halves of
the universal shaft should mesh with each other at least 1/3 of the total length of the universal shaft in every three-
point hydraulics position.
In case of problems, contact a qualified workshop or the seller of the
drive shaft. Secure the PTO guard after installation on the tractor by
hooking the safety chain either to the tractor or to the drive unit.
7.3
Adjusting the working height
The working height of the machine is determined by the position of
the rear roller and the adjustment of the lateral skids. When the roller
is raised, the knives approach the ground. When the roller is lowered,
the knives move away from the ground. After adjusting the working
height, ensure that the blades pass above the ground. Direct contact
with the ground will cause faster wear or lead to damage to the
machine. Incorrect height adjustment also allows objects to be
ejected from the mower unit.
