mounted under the cutting deck, on the right side. This baffle is used to evenly distribute the cut grass
when the operator mows grass up to 12/15 cm max.
ENGINE BELT – CUTTING DECK BELT
The engine – blade belt is a TYPE B self-adjusting belt, needing therefore no adjustment. If the belt
becomes twisted or comes off, check the parameters below, keeping the cutter deck in the highest
position:
1) 210 mm from the front cutting deck border to the ground (fig. 24).
2) 210 mm from the rear cutting deck border to the ground (fig. 24A).
3) Use the adjusting screws to adjust the levelness of the cutting deck, if necessary (fig. 14 – 14A).
4) IMPORTANT: beside the cutting deck pulley there is a belt guide (fig. 12, C) equipped with bearings to
maintain the belt in the correct position when it oscillates. Should this component be dismounted, take
care when remounting it in its original position.
5) Lubricate with grease the belt tightener (fig. 12, B).
REPLACEMENT OF THE ENGINE BELT – CUTTING DECK BELT
The movement is transmitted from the engine to the blades by means of a 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 service centre.
To replace the belt going from the electromagnetic clutch to the cutting deck pulley follow the instructions
below:
1) loosen the two screws fixing the belt guide roller to the cutting deck (fig. 12) and move it away from
the pulley, taking care when remounting it in its original position.
2) remove the belt from the cutting deck pulley.
3) remove the zinc bracket located next to the electromagnetic clutch (fig. 12B). Important: remount the
bracket at the same original distance from the clutch. Should this distance not be respected, the belt
could be discharged from its seat during work.
4) remove the belt and taking care when remounting the new one in the original position on the double
belt tightener.
BLADE ROTATION
To engage and disengage the blade press the button (fig. 1, n. 1). The engine must be running at
medium r.p.m. (see label on the throttle lever) and the machine must be outside the area to be cut. Do
not engage the blade with the engine running at max. r.p.m. The machine is equipped with an
electromagnetic clutch which also brakes the blade during disengagement. The blade must stop within 5
seconds with the engine at max. r.p.m. Should this not be the case, remove the spacer mounted under
the pad of the blade brake (fig. 25). IMPORTANT: This operation must be carried out by an
authorized after-sales service center. Do not use the machine if the blade does not stop within 5
seconds from disengagement with the engine at max. r.p.m.
ENGINE – HYDROSTATIC TRANSMISSION BELT
Whenever there is a change in belt length (causing therefore its malfunctioning), the tension can be
regulated through the adjustment screw (fig. 16). Take care not to completely compress the spring under
the nut: he spring must be kept set at 44 mm (see red arrow – fig. 16).
REPLACEMENT OF THE ENGINE – HYDROSTATIC TRANSMISSION BELTS
The movement is transmitted from the engine to the hydraulic transmission 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 service centre. To
replace the two belts going from the engine to the angle-gearbox and from the angle-gearbox to the
hydraulic engine follow the instructions below:
1) remove the upper grid.
2) loosen nut and counternut of the belt tightener (fig. 16).
3) remove the angle-gearbox/hydraulic engine belt.
4) detach the power cable and the locking bracket of the electromagnetic clutch.
5) remove the engine/ angle-gearbox belt.
ALWAYS USE ORIGINAL BELTS!
