CHECKING THE BLADES AND CUTTING DECK
A blunt blade tears the grass, therefore the cutting edges of both blades must be sharpened. To remove a
blade, take hold of it firmly, wearing work gloves, and unscrew the central screw (3 fig. 9), remembering that
the screw has a right – hand thread. Sharpen both cutting edges using a medium – grain grinding wheel and
check that the blade is balanced by standing it on a round bar inserted in the central hole. Fit the two cutting
blades following the diagram in fig. 9.
CAUTION!
Tighten the fixing screw (3 fig. 9) firmly. Always replace damaged or crooked blades; never attempt to repair
them! When fitting, always follow the diagram fig. 9.
ALWAYS USE ORIGINAL BLADES! If they are worn they can be turned round since they have two cutting
edges. Always check that the blade bolts are not worn or damaged.
ADJUSTING THE CUTTING DECK
Levelness of the cutting deck is essential in order to obtain an evenly mown lawn.
Park the mower on a flat surface and check that the tyre pressure is correct. Adjust the 4 adjustment devices
(fig. 17 – 17A), so that the edge of the cutting plate is at the same distance from the floor, 110 mm, on both
sides (with the operator sitting on board and the cutting deck in the lowest position, fig. 18/A). If you are
unable to level off the deck, contact your Dealer.
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 illustrated in fig. 18/A, 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 (A,
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 button fig.1 ref. 4 . When rotation is engaged, the engine must be
running at medium rpm and the machine must not be in the grass for cutting. The blade is disengaged when
the PTO switch is moved to OFF ( fig.1 ref. 4). The blade will also stop when the gear lever is positioned on
TRANSFER fig. 2.
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 the drive belt, the belt guide fig. 19 beside the deck pulley has to be removed; release the
belt stretcher spring (fig. 20) and remove the casing.
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 the idle position (B, fig. 22). In the position (A)
shown in fig. 22 the machine is in working condition.
