Coulter; Folding Frame; Inter-Row Adjustment; Stopping The Machine - breviglieri mg-4 Manuel D'utilisation Et D'entretien

Comply with the following instructions to fit the fertilizer spreader
to the interrow tiller:
- Remove the protective casing from the drive shaft (1 Fig. 14).
- Remove the terminal guard from the frame (2 Fig. 14).
(these two operations must only be carried out on the left-hand
side of the interrow tiller).
- In the version with the folding frame, keep the two folding parts
up, then remove the protective casings from the hexagonal drive
shaft and take out the transmission half-coupling (this operation
must only be carried out on the left-hand side of the interrow tiller).
- Position the fertilizer spreader on the frame, center it along the
length and lock it in place with the relative bolts.
- Insert the pulley into the drive shaft and lock it in place. Make
sure that it is aligned with the fixed one on the fertilizer spreader.
- Insert the driving belt and tighten it by means of the relative
bolts (see Fig. 15). Pull upwards with the lever (1 Fig. 15) to
tighten the main belt, then lock the bolt (2 Fig. 15). To tighten
the second belt, first loosen the bolt (3 Fig. 15) then tighten the
belt by hand.
The belt is tightened correctly when it gives about 5 mm.
- Assemble the external half-casing of the pulleys.
- Assemble the drive shaft guards.
- Fit the protective ends back on the ends of the frame.
- Assemble the hose pipes on the hopper outlets and fix them in
place with the relative clamps. Lock them in the lower part to
the fixed supports on the casing of the tilling units.
How to adjust the amount of fertilizer.
There is a lever that opens or shuts the fertilizing point under
each hopper outlet (1 Fig. 16).
Use the lever above the third-point hitch (A Fig. 17) to adjust the
quantity of fertilizer.
The graduated scale allows the operator to establish the right
opening degree for each type of fertilizer.

4.10 COULTER

WARNING
Always take all the possible precautions before working on
the machine in any way. Turn off the tractor engine, disen-
gage the power take-off and apply the parking brake.
Wear work gloves and use suitable tools in a good condition.
This accessory can be supplied separately. It earths up the roots
of the plants automatically during the tilling operation.
It is fitted into the relative hole (1 Fig. 18) in the casing of the tilling
unit, after which the rod of the spring should be inserted into the
relative housing (2 Fig. 18).
The depth of the accessory must be adjusted by raising or lower-
ing it on its support (3 Fig. 18) after the tilling depth has been
regulated.
Coulter slant adjustment
Using the nut (4 Fig. 18) above the spring, the coulter can be
slanted in relation to the ground (Fig. 18).
Tighten the nut to raise the rear, loosen it to lower the rear part.
Once the slant has been adjusted, increase or reduce the ad-
herence to the ground depending on the conformation of this
latter, using the ring nut (5 Fig. 18) under the spring.
Turn the nut towards the right to increase the adherence or
towards the left to reduce it.
To adjust the ridging height, open the two parts of the coulter to
a greater or lesser degree by removing the safety pin and mov-
ing the levers to the required hole (Fig. 19), depending on the
width of the actual crop.

4.11 FOLDING FRAME

The two ends of the frame in models wider than 3 m are folding so
as to narrow the actual frame itself to 2.55 m and thereby facilitate
road circulation.
Comply with the following instructions to lower the ends:
- Remove the safety pin (1 Fig. 20) with the relative split pin.
- Pull the end towards the ground, taking care not to put the hands
under the cross-member, then insert the plug and insert the
safety pin.
- Connect the drive shaft coupling and lock it in place (see Fig.
21).

4.12 INTER-ROW ADJUSTMENT

Always take all the possible precautions before working on
the machine in any way. Turn off the tractor engine, disen-
gage the power take-off and apply the parking brake.
Wear work gloves and use suitable tools in a good condition.
To adjust the working width, loosen the brackets (1 Fig. 22) that
lock the tilling blades and move them along the frame. Remem-
ber that the three-point hitch must be as central as possible in
relation to the frame.
Once the tilling blades have been adjusted, position the bearing
wheels by loosening the relative locking mechanisms (2 Fig. 22)
and allowing them to slide along the frame.

4.13 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.

4.13.1 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.
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.
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.
