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 ref. A).
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. 20).
BLADE ROTATION
Rotation is started and stopped using the lever 1 fig. 2.
When rotation is engaged, the engine must be running at medium rpm and the machine must not be in the grass
for cutting.
The blades are disengaged when the PTO lever is moved to OFF (1, fig. 2). The blade must stop within 5 seconds;
if this is not the case, adjust the brake using the register (fig.19).
N.B. This operation must be carried out by an authorised after-sales service centre.
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 three belt guides beside the deck pulley have to be removed (A, fig. 19); release
the belt stretcher spring (A, fig. 21) and remove the belt guide (B, fig. 21).
ALWAYS USE ORIGINAL BELTS!
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.
