4. SET UP
The hoe is delivered fully assembled and equipped with a driveshaft with friction clutch (clutch discs)
and related operating manual.
When the machine is delivered, check that there is no damage to the hoe or driveshaft. In case of
damage or missing parts immediately notify the manufacturer or your dealer.
4.1. Connecting to the tractor
To connect the hoe to the tractor the operator must do the following:
• drive the tractor in reverse, up to align the rear lifting arms to lower hitches of the hoe in parking;
• set the tractor's parking brake, stop engine, remove the ignition key and get off the tractor;
• connect the lifting arms of the tractor to the lower hitches of the hoe, through the use of the pins
and the relative safety split pins;
• raise the hoe until PTOs of tractor and machine are at the same height, then adjust the 3-point
top link so that the front of the machine is leveled to the back (the axis of the hoe PTO must be
parallel to the ground), in order to limit stress transmitted to the hoe through the cardan shaft;
• make sure that left side of the hoe is leveled with the right, by adjusting the tractor lifting arms,
then lock the arms to prevent swinging that could compromise the stability of tractor and
machine;
• finally adjust the parking stand, placing it at the highest point by means of the related elastic pin.
4.2. Driveline Installation
Before installing the driveshaft, the operator must read the manuals of driveshaft and tractor,
checking in particular that rpm and direction of rotation of the tractor PTO match those of the hoe.
If the direction of rotation of the PTO tractor does not match that of the hoe, contact the
manufacturer or your dealer.
To connect the driveshaft to the tractor and implement, the operator must:

FMA SERIES
19
• park tractor and hoe on a flat surface, with parking brake set, engine off, and ignition key
removed;
• check that safety devices of driveshaft, hoe and tractor are in good condition, otherwise provide
for their replacement;
• remove the PTO shield of the hoe through the fixing screws;
• position the driveshaft with clutch turned towards the implement side;
• insert the clutch hub on the hoe PTO, then ensure its tightening onto shaft through its fastener;
• replace the PTO shield of the hoe through the fixing screws;
• insert the driveshaft yoke on the tractor PTO, then ensure its tightening onto shaft through its
fastener;
• hook to the tractor and hoe the two retaining chains of the the driveline shielding, to prevent
shielding rotation during functioning of the machine.
Driveline Length Check
Before operating the hoe, ensure that the size of driveshaft is adequate. The driveshaft supplied
with the machine has a standard length, therefore it may need an adaptation of the length,
depending of the tractor which the hoe is combined.
The length of the driveshaft must be such to:
• avoid bottom out of the transmission tubes, when the driveshaft is in compressed position (when
hoe is raised up off the ground);
• Ensure an overlapping of the transmission tubes enough to transmit the torque required, when
the driveshaft is in max extension (when hoe is in its lowest position in the ground).
When the driveshaft is at its minimum length (max compressed position), there must be at least a 2
cm of distance between the ends of each transmission tube and the yokes side.
When the driveshaft is at its maximum operational extension, there must be an overlap between
the tubes profiles of 15 cm at least.
A driveshaft too long may cause structural damages to the tractor and machine. If the driveshaft is
too long, it may be adapted by removing it and shortening the tubes according to the instructions
provided by the manufacturer in its use and maintenance manual.
A driveshaft too short can cause disengage of the tubes during operation, with severe hazard for
the operator and structural damage to the tractor and machine. If the driveshaft is too short, it must
be replaced with a longer one. In this case contact the manufacturer or your dealer.
