There is a spring device for tightening the belt (37). When the “X” distance between the indicator (38)
and the base (39) reaches 3 mm (or more) it is necessary to tighten the belts using the nuts (40) to
tightenuntilreachingtheindicator(38)thattouchesthebase(39).
CAUTION:
The “V” belts are the most critical parts in the machine, thus it is essential that routine and adequate
maintenance is performed. It is always important to adapt the speed of the tractor to the working
