Belt tension
Adjusting the tension:
- Tighten screw (1) using the 18mm box spanner
supplied with the machine.
- The spacer tube (2) must come into contact with leg
(3) and washer (4).
Before carrying out any maintenance or
repairs on the machine, switch off the tractor
engine, remove ignition key, wait until all
moving parts have come to a standstill and
apply park brake.
Regularly check belt tension and in particular
during the first hours of use.
Never replace belts individually.
Replace belts in full sets.
During the initial assembly or when installing
a new set of belts, give screw (1) 2 additional
turns to compensate for the inital stretch of a
new set of belts.
