BLADE – ENGINE BELT
To adjust the belt tension operate on the register (fig. 18). If the belt becomes twisted or comes off, make all the checks and
adjustments stated below, keeping the deck at the lowest position. Take care when positioning the belt guides; move them
towards the belt, checking the deck at the various height settings (fig 19).
HYDROSTATIC AXLE – ENGINE BELTS
These belts are self-adjusting and do not require any adjustment. Simply check the spring tension. To replace the belts,
release the tension spring (fig. 21).
BLADE ROTATION
Rotation is started and stopped using the switch (no. 6, fig. 1).
When rotation is engaged the engine must be running at medium rpm and the machine must not be in the grass for cutting.
Never start the blades with the engine at maximum rpm. The machine is equipped with an electromagnetic clutch which also
brakes the blade during disengagement. The blades are also disengaged automatically when the cutting height adjuster
lever is moved to the highest position. CAUTION: for safety reasons if the operator pushes down the height adjustment lever
from the highest position with the PTO button engaged, the blades do not start automatically. To start the blade the PTO
button must be switched off and switched on again.
The blade must stop within 5 seconds, if this is not the case, adjust the 3 nuts of the electromagnetic clutch, placing a 0.3
mm feeler gauge under the brake plate. N.B. This operation must be carried out by an authorized after-sales service
center.
CHANGING THE BELTS
The movement is transmitted from the motor to the hydraulic transmission and to the blades by means of two v-belts.
Replace the belts as soon as they show signs of wear! Their replacement and subsequent adjustment are fairly complex
procedures and must be carried out by an Authorised After-Sales Service Centre. For cutting deck drive belt, the belt guide
beside the deck pulley has to be removed (fig. 19); release the belt stretcher spring (Fig.20).
ALWAYS USE ORIGINAL BELTS!
DIFFERENTIAL LOCK CHAINS
On both sides of the differential lock axle there are two chain tensioners. To regulate them slightly unlock the two nuts (fig.
28, ref. A) and use the screw (fig. 28, ref. B). CAUTION: In order not to overload the transmission, do not tension the chain.
The chain should move about 1 mm.
TRACTION RELEASE LEVER
The traction release device is located at the back of the machine (fig. 22); if the machine breaks down, to allow it to be towed
or moved by hand, move the lever to idle position (B, fig. 22). In the position (A) shown in fig. 22 the machine is in working
condition.
