4.3 BRAKE ADJUSTMENT
Reduced braking power is corrected by adjusting
the spring on the brake rod.
➤
In mechanical drive models:
Remove the fuel tank [see 5.4].
➤
In the hydrostatic drive models:
Use a socket spanner to make the adjustment
through the hole
(1)
on the rear plate.
The adjustment is to be made with the parking
brake engaged and consists of altering the length of
the spring
(2)
to the best measurement. The braking
capacity is increased by screwing the nut down on
the rod (and thus shortening the length of the
spring).
Loosen the nut (4) which retains the bracket
(5)
and
then turn the nut
(6)
so that the length

of the
spring
(2)
is:
– 43,5 ÷ 45,5 mm
➤
In mechanical drive
models
– 45 ÷ 47 mm

measured from the inside of the washers. When the
adjustment has been made, tighten the nut
(4)
.
Never go under these amounts to avoid overloading
the brake unit.
When the adjustments have been made, the park-
ing brake should prevent the lawn-tractor from
moving on a slope of 30% (16°) with the driver in
position.
➤
In mechanical drive models:
If braking is still poor or uneven even after having
made the adjustment, remove the control rod
(3)
from the lever
(7)
and check that this lever has a
free movement of 20 mm (measured vertically
next to the pin rod) before beginning the braking
action. If this is not the case, the free movement
can be adjusted with the screw
(8)
, unless the
