A stretched cable and changes in the length of the belt can impair
the bladesʼ engagement or rotation.
In this case, you have to work on the adjuster according to the dif-
ferent methods provided for each model.
Turn the adjusting nut (1) until the correct spring length (2) is
113 ÷ 115 mm
In any event, if the engagement is unable to normally drive the belt
or the blades do not stop within a few seconds after adjustment, im-
mediately contact your Dealer.
6.3.4 Brake adjustment
If the braking distance becomes
longer than the amount indicated
5.3.6), the brake spring will
need to be adjusted.
The adjustment will need to be
made while the parking brake is
engaged. Access for making this
adjustment is by taking off the in-
spection hatch on the tunnel be-
neath the seat.
Loosen the nut (1) which holds the
bracket (2) and turn the nut (3) un-
til the length of the spring is:
A = 47,5 - 49,5 mm
B = 45 - 47 mm
measured inside the washers. When the adjustment has been
made, tighten the nut (1).
Do not screw below these levels to avoid over-
loading the brake unit.
90 ÷ 91 mm
If the brake still does not work properly even
after this adjustment, immediately contact your Dealer . DO

Access for making this adjustment
is by taking off the inspection hatch
on the tunnel beneath the seat.
Loosen the locking nuts (2) and
tighten or loosen the screw (1) as
much as necessary for a length
«A» of the spring (3) of:
A = 129 - 131 mm
A = 109 - 111 mm
measured to the outside of the end of the spring. When the adjust-
ment has been made, tighten the nuts (2).
When replacing the belt, take great care when
using for the first few times as engagement may be sudden until
the belt is sufficiently run in.
6.3.6 Adjustment of the spring of the pawl for hooking
If the grass-catcher tends to jump
about and to open up when going
over rough ground, or if it is difficult
to hook back on after being emp-
tied, the tension of the spring will
need to be adjusted(1).
Change the hooking point by using
one of the holes (2) until the re-
quired result is achieved.
