4.2.1 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
(18 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

4.4 DURING WORK

Begin work with the PTO at full rate. Gradually dig the implement into the ground. Do not depress the accelerator pedal too much
with the PTO engaged. To break up the soil to the required degree, you must consider several factors, i.e.:
▪
The nature of the soil (medium consistency, sandy, clayey, etc.)
▪
The work depth
▪
The ground speed of the tractor
