4.10 Drive belt adjustment (Hydrostatic drive models)
NOTE:
If it seems that the forward drive is not working
properly after a long period of use or after replacing the belt,
this may be caused by a change in length of the belt. It will
therefore be necessary to adjust the screw coupling.
1. Put the lawn-tractor into a vertical position (see chap.
2.4).
2. Position the end of the screw coupling spring [1] in one of
the three holes on the lever [2] in order to reach the
indicated length [A] measured from the outer part of the
eyelets.
