4.6 TINES
The tines with which the machine is equipped are suitable for
cultivation work in soil of normal consistency. Check the tines each
day to make sure they are not worn or broken. If the tines should
accidentally bend (or break) during work, they must be immedi-
ately replaced by mounting new ones in the identical position.
If several tines must be replaced, it is advisable to demount and
mount one tine at a time to avoid positioning errors.
The tines are available in different shapes:
- helical shaped for normal and tenacious soils;
- square shaped for loose and normal soils.
The cutting edge of the tines must always point in the same direc-
tion as the rotor turns, according to the phase depicted in Fig. 1
ref. 10.
DANGER
Tine replacement is a dangerous operation.
Proceed in the following way to replace the tines:
- Park the tractor on a flat surface with the machine hitched, then
raise the machine with the power lift;
- Insert two strong bearing stands at the sides of the machine;
- Lower the machine on to the stands, turn off the tractor engine
and apply the parking brake.
WARNING
The heads of the bolts that fix the tines must by on the side
of the tines themselves while the nut and relative washer must
be on the flange side.
Comply with the driving torque values given in the table be-
low.
If tines must be replaced, make sure that the new ones are
mounted in the same positions as the old (see 10 Fig. 1).

DANGER
If the tines/blades clog, it is strictly forbidden to attempt to
clean the machine whilst it is operating. First disengage the
PTO, stop the tractor and engage the parking brake.
Wait until all moving parts have come to a complete stand-
still, then proceed with the cleaning operations with the ut-
most care.
4.7
SIDE SHIFTING ROTARY HOE
The side shifting rotary hoe is a very versatile machine.
The third-point unit can be manually shifted from the center of the
rotary hoe framework in order to work nearer to the plants.
The side shifting movement is obtained by means of a hexagonal
drive shaft (protected by a shield) on which the final drive slides.
Just clean the framework and slideways on which the carriage of
the third point with the final drive moves.
Slacken off the relative fixing bolts, allow the carriage of the fixed
third point to slide to the required position, then tighten the previ-
ously loosened bolts again.
4.8 FRONT WHEELS
On request, the machine can be supplied with front wheels for
depth adjustment purposes. The adjustments are made by loos-
ening the screw (A Fig. 8) and lowering or raising the wheel. In
the former case, the depth becomes more shallow while in the
latter case it increases. Always remember to tighten the lock nut
sufficiently.
If the wheels are supplied separately, comply with the following
instructions to mount them on the machine:
- Mount the wheel support on the square section front tube and
fix it in place with the supplied U-bolts, taking care to tighten the
relative nuts to the correct extent.
When you remove the wheels, keep the side skids fully raised
since in this case, they only act as a protection.
4.9 STOPPING THE MACHINE
At the end of the job, the operator must:
- Disengage the tractor PTO.
- Lower the machine to the ground by means of the power lift.
- Stop the tractor and engage the parking brake.
- Make sure that all parts of the machine are at a standstill.
Only after the above mentioned operations have been carried out
may the operator leave the tractor unattended.
4.9.1 PARKING
- At the end of the job, the machine must be parked on a flat,
suitable surface.
- Stop the tractor and apply the parking brake.
- With the tractor stopped and all components at a complete stand-
still, remove the driveline from the PTO of the tractor.
- Unhitched the machine from the tractor.
WARNING
The place in which the machine is parked must be:
- Dry.
- Sheltered from adverse weather conditions.
- Guarded or locked up to prevent children or unauthorized
persons from freely accessing the machine.
CAUTION
If the machine is to remain idle for a long period of time, lu-
bricate the parts subject to wear and store the machine in a
dry, sheltered place, covered with a plastic sheet.
This will ensure that the machine is in the ideal condition
when required again.
