4.5 ALIGNING THE CUTTING DECK
Lowering of the cutting deck is controlled by a
linkage operated by the lever and is guided by two
front articulation connecting rods.
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.
a)
a combined adjustment to the parallel and the
minimum height front and back
b)
adjusting the regularity of raising and lowering
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
adjustments as in point “
A
”.
N.B.
– When aligning the cutting plate it could be
necessary to remove the belt guards; in this case
the guards must always be replaced after
adjustment
.
A) The combined adjustment to the parallel and
the minimum height front and back
Put the lawn-tractor 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)
Put the height lever in position «1».
Unscrew the nuts
(3 - 5 - 7)
and locknuts
(4 - 6 - 8)
so that the deck rests on the blocks.
Turn the nuts
(9)
(first remove the central covering)
so that the rear left connecting rod
(10)
starts mov-
ing at the slightest movement of the lifting lever, and
then secure it in place.
Screw down the rear left nut
(3)
until the rear edge
of the cutting deck begins to rise,
Screw down the front nuts
(5 - 7)
until the front
edge of the cutting deck begins to rise evenly, both
on the right and left side.
Screw down the three locknuts
(4 - 6 - 8)
.
Check that the deck rises and lowers regularly as
indicated in point “
B
”.
