MAINTAINANCE 130MP CUTTING DECK
To ensure the deck belt works properly and to have a uniform cut, please follow these instructions:
– put the cutting deck in its lowest position
–
–
If you see that the length of the belt has changed, resulting in malfunctioning, you can regulate the belt tension
ENGINE - HYDROSTATIC TRANSMISSION BELT
Whenever there is a change in belt length and subsequent malfunctioning, the tension can be regulated
by means of the adjustment device (Fig. 16). Take care not to compress the spring beneath the unit
completely; belts must be neither too taut nor slack. The spring must be kept set at 44 mm (Fig. 16).
BLADE ROTATION
Rotation is started and stopped using the button 1 Fig. 1.
When rotation is engaged, the engine must be running at medium rpm (see throttle sticker) 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!!! When the lever is lowered the blade starts up 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 authorised after-sales service centre.
CHANGING THE BELTS
The movement is transmitted from the engine to the hydraulic transmission and to the blades by means
of two vee-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-engine belt, the belt guides of the deck pulley have to be removed; release the belt
stretcher spring (Fig. 15/B).
For the two transmission and hydraulic motor drive belts proceed as follows:
1) remove the rear and top grille
2) undo the belt stretcher nut (Fig. 16).
ALWAYS USE ORIGINAL BELTS!
TRACTION RELEASE LEVER
The traction release device is located behind the seat; if the machine breaks down, to allow it to be towed
in working condition. Check that during operation the hydraulic motor piston does not remain pressed
