a) ATTACHING THE MACHINE TO THE TRACTOR
The attachment of the machine to the tractor is simple but dangerous. Carry out the
operation being extremely careful and strictly following these instructions. Make sure
that there are no persons or objects within the operating range of the machine and
tractor. Check that all the signs and symbols are on the machine and are legible.
Check that the tractor is in good condition and is suitable for pulling and working
with this machine. Always consult the tractor operator’s manual.
The attachment to the tractor consists of joining the machine’s hitch 1 to that of the
tractor 2 or to the bar 3 attached to the tractor lifting arms.
First of all (see Box A) bring the machine hitch 1 to the height of the tractor hitch 2
by adjusting the stand 4. (If instead you attach the machine to the bar 3, the correct
coupling height is achieved by raising or lowering the lifting arms).
Now, if the machine hitch 1 is roughly horizontal (parallel to the ground) you can
hitch it to the tractor. If instead the hitch 1 is inclined too much upward E or
downward F (see Box A), it must be brought back into a horizontal position. To do
this (see Box B) you must unscrew nut 7, remove washers 8, 9 and bolt 10. Now
rotate the hitch 1 and bring it to the hole H among the five holes available on the
drawbar that allows it to be fastened in a roughly horizontal position. If it is difficult
to rotate hitch 1, loosen the nut-screw unit G. To fasten hitch 1 in the chosen hole H,
use the bolt 10, the washers 9-8 and nut 7. Tighten the nut-screw unit G if it had been
loosened.
At this point, whether hitch 1 is attached to tractor hitch 2 or to the bar 3, you must
fasten it using a pin 5 of adequate size and capacity for the weight of the machine and
with a pin 6 (see Box C).
That described above also applies if the machine has been fitted with the optional
hitch 11 (see Box D).
NB: in this case, since the machine was assembled just before transporting it and
subsequently before working, you will have to do the functional tests (see paragraph
“b”), but this procedure should be carried out every time you have to attach the
machine to the tractor.
