14.3 ADJUSTINGTHEGRASSCATCHERALIGNMENT
For good operation, it is very important to ensure a perfect coupling
between the grass catcher and the loading chute in the closed position
(g.30).
Fig. 30
To do this, proceed as follows:
1. Bring the grass catcher into the fully closed position and check the
coupling with the chute;
2. Ifthegasketdoesnotsealproperlyoristooattened,loosenthe
boltssecuringthegrasscatchertotherearpart(g.31/Aand31/B);
3. Loosen the safety nut at the top of the central hydraulic cylinder
rod. Tighten or loosen the cylinder rod (g. 31/C) to obtain the
desired movement of the grass catcher, so that the seal is slightly
attenedandthegrasscatcherisalignedwiththechute;
4. If necessary, the position can also be adjusted by acting on the
lifting cylinders (g. 32): lengthening the rods of the cylinders
moves the grass catcher further and upwards from the chute,
shortening the rods of the cylinders moves the grass catcher closer
and downwards towards the chute.
 IMPORTANT: for correct operation of the hydraulic grass
catcher lift, the cylindersmust be adjusted evenly to the left and
righthandsides.

possible to change the tension of the connected cable and thus anticipate
or delay the opening of the grass catcher when unloading.

14.5 ADJUSTINGTHETRAVELPEDALNEUTRAL
POSITION
If the machine does not come to a complete stop when the drive pedal
is in neutral, the neutral position of the forward/reverse pedal can be
adjusted using the adjuster provided.
The neutral position adjustment is to be carried out with the engine
running and with the machine safely placed on stands, with the front
wheels raised off the ground.
Remove the steering column cover then loosen the two bolts and adjust
theforwardspringretainingbracket(g.34)sothatthewheelscometoa
complete stop; retighten the two bolts when the adjustment is complete.
