4.2 HITCHING TO THE TRACTOR

DANGER
Hitching to the tractor could be a dangerous operation. Take
great care and strictly comply with the instructions.
In order to achieve the utmost stability and ensure that the entire
operation is carried out in safe conditions, the folding harrow
must be opened before it is hitched to the tractor.
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 configura-
tion 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 posi-
tion, then back up the tractor towards the machine.
▪
Having reached the right position, turn off the tractor
engine then fit the driveline first into the PTO of the
machine and then to the tractor PTO. Make sure that it is
firmly locked in position.
▪
Move the power lift bars near and fit them into the plates.
Insert the plug and lock in place with the supplied split
pins.
▪
Since the power lift links of each tractor are a certain
length and have a hole of a certain diameter, you must
find the most suitable position for the tractor you use by
inserting the pins into the relative holes according to your
needs and depending on the diameter.
▪
Lock the power lift bars with the relative chains and idlers
parallel to the tractor. This must be done to prevent the
machine from swinging sideways.
▪
Insert the driveline and make sure that it is perfectly
locked on to the tractor PTO. Check that the guard is free
to turn. Fix the driveline shield with the relative chain.
Remove the driveline support and fix it to the relative
hitch on the linkage.
DANGER
Take the utmost care when you insert the driveline. Make
sure that it is firmly locked on to the tractor PTO and on the
machine. Also comply with the indications in the instruction
manual supplied with each driveline.
Make sure that the driveline shield, fixed with the relative chains,
is free to turn without obstructions. Also check the protective
shields on the tractor and on the implement.If some guard is not
in perfect working order, it must be immediately replaced with
a new guard. It is very important to ensure that the protective
shields on both sides overlap the driveline ones by at least 2" in.
▪
Connect the upper third point and adjust the top link in
the correct way, making sure that the upper surface of
the machine is parallel to the ground. This is very impor-
tant as parallelism between the axis of the machine and
that of the tractor PTO is obtained in this way.

4.3 TRANSPORT POSITION

The following expressions must be observed to ensure that the
tractor-machine assembly is stable (Fig.5):
T
0,2
Z
d
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)}
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 COMBINED MACHINE WITH SEED DRILL PRODRILL-FT
In the combination of the power harrow with the seed drill please
pay greatest attention to the weight of the rear seeder bars
However, if the hydraulic seed drill hitch is installed by the end
user, remember to ensure that:
▪
Once the frame has been mounted on the machine, in
order to raise the seed drill with the seeds, the overall
weight of the combination must not exceed the value
given in the operation and maintenance manual.
