General informations
Lowering of the cutting deck is controlled by a
linkage activated by the lever and is moved by
two connecting rods at the front.
In order to get a good cut it is essential that the
cutting deck is parallel with the ground crosswise,
and slightly lower at the front.
There are two types of possible adjustments:
a) a combined adjustment to the parallel and the
minimum front and back height, to be carried
out if the cutting is irregular;
b) adjustment of the longitudinal deck position,
is only necessary when, during cutting deck
replacement operations, the original position
has been lost and the correct distance to the
engine pulley must be restored.

ALIGNING THE CUTTING DECK
Check the tyre pressures. If one or more tyres have
been replaced or you find differences in diameter, do
not attempt to compensate these differences by
giving different tyre pressures, but make the ad-
justments as in point "A".
A) Combined adjustment to the parallel and
the minimum front and rear height
Put the machine onto a flat and stable surface (such
as a work bench) and put blocks beneath the cutting
deck in line with the centre lines of the blades:
– at the front 26 mm (1)
– at the rear 32 mm (2)
Set the lifting lever to position «1» and slacken off the
nuts (3), screws (5) and locknuts (4 - 6) on both the
right and left hand sides, so that the deck rests firmly
on the blocks.
Turn both the rear screws (5) until the rear of the deck
begins to rise both at the right and the left, and then
tighten the relevant locknuts (6).
1 h = 26 mm
CHAPTER
4.5a
Push the two connecting rods (7) to the back and
screw down the two nuts (3) on each rod until the front
part of the deck just begins to rise both at the right and
the left, and then tighten the relevant locknuts (4).
B) Adjustment of the longitudinal position
NOTE These adjustments are not performed to align
the cutting deck, but simply to determine the distance
of the deck from the motor pulley, so as to achieve
h = 32 mm
