Coupling the Forage Chopper machine to the three-point linkage of the tractor hydraulic
system (first the first lower arms and then the upper arm).
If it is necessary to shorten the driveshaft, proceed as follows: Separate the two parts of the
driveshaft (male/female).
Couple the “female” side to the tractor power take-off and the “male” side to the machine.
Place the two parts of the driveshaft side-by-side and mark the place for cutting, leaving about
25 mm of play, on each end (see the following figures).
Remove the driveshaft, cut the extra parts off from the male and female sides.
Then assemble the driveshaft again, see if the ends are aligned, as shown in the following
figure.

Coupling to the tractor and installing the driveshaft
Caution!
After coupling, carefully check if the driveshaft is well-latched to the tractor
and machine axles. If the moving driveshaft disengages, it can result in a
serious accident.
Notes:
The parts cut from the solid and tubular parts of the driveshaft must be the same
length. It is necessary to leave a minimum of 25 mm of play at both ends of the
driveshaft.
The instructions for cutting, lubricating, maintenance, and installing the driveshaft
protective cover are found and described in the pamphlet supplied by the
manufacturer.
It is the exclusive responsibility of the authorized JF Máquinas reseller to prepare
the driveshaft and try out the first operation of the machine.
