If the clutch still slips even when all the nuts have been tightened, the friction plates must be changed as they could be worn
or because the springs have become slack. Never fully tighten the nuts as this eliminates the function of the springs and
clutch itself, to the detriment of the transmission components.

4.1.3 WORK POSITION

The operator must be seated in the driving seat of the tractor when the machine is working since only from that position is
he able to act correctly. Before he leaves the driving seat, the operator must stop the machine, apply the parking brake and
turn off the tractor engine.

4.2 HITCHING TO THE TRACTOR

Hitching to the tractor could be a dangerous operation. Take great care and strictly comply with the instructions.
Proceed in the following way to hitch the machine to the tractor in the correct way:
▪
Make sure that you are using a tractor whose configuration suits the machine in question.
▪
Make sure that there are no objects, bystanders and/or animals in the immediate vicinity of the machine and that the PTO
is disengaged.
▪
Make sure that the machine is in a stable, horizontal position, then back up the tractor towards the machine.
▪
Drive the tractor near to the implement with caution and adapt the height of the lift links to the height of the hitching pins.
▪
Move the power lift bars near and fit them on to the hitching pins. Now lock in place with the supplied split pins.
▪
Switch off the tractor engine.
▪
Connect the top link and adjust it so that the machine is on the flat.
▪
Lock the power lift bars with the relative chains and parallel idlers on the tractor. This must be done to prevent the machine
from swinging sideways.
▪
Fit the driveline into the machine's power take-off and make sure that it is perfectly locked in the correct position.
▪
Make sure that the shield is free to turn. Fasten the shield with the relative chain. Remove the support from the driveline (
Fig. 1) and fix it on the relative hook.
▪
Switch on the tractor engine, slightly lift the machine from the ground and raise the bearing stands.

4.3 TRANSPORT POSITION

The following expressions must be observed to ensure that the tractor-machine assembly is stable (Fig.5):
M < 0,3T
........................................................... (prudential value)
Z > {[(M x s) – (0,2T x i)] / (d x i)}
where:
i = tractor's wheelbase
d = horizontal distance between the center of gravity of the front ballast and the tractor's front axle
s = horizontal distance between the center of gravity of the machine and the tractor's rear axle
T = weight of the tractor in running order
Z = ballast weight
M = weight of the machine

M x s < 0,2T x i + Z(d+i)
