PTO BELT
Attention! This is a special belt, USE ORIGINAL BELTS.
To replace it, loosen the tie rod by acting on the corresponding lever (fig. 17, ref. A) and remove the belt
from the pulley on the cutting deck. Loosen the electromagnetic clutch protection (fig. 21, ref. A) and let it
slide towards the rear part of the machine. In this way it is possible to remove the belt completely from
the electromagnetic clutch. IMPORTANT: there is no need to remove other components, the operator
can easily remove the belt as shown (fig. 8, ref. A).
To set the tension use a no. 13 spanner to turn the nut that adjusts the tension spring (fig. 19, ref. B).
The spring must be compressed to a length of 85 mm.
