4.3 HITCHING TO THE TRACTOR
DANGER
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 (

) and fix it on the relative hook.
Switch on the tractor engine, slightly lift the machine from the ground and raise the bearing stands.
▪
4.4 TRANSPORT POSITION
The following expressions must be observed to ensure that the tractor-machine assembly is stable (Fig.
5
):
M x s < 0,2T x i + Z(d+i)
M < 0,3T
........................................................... (prudential value)
Z > {[(M x s) – (0,2T x i)] / (d x i)}
.....
(for calculating the ballast)
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
