How To Work; Useful Tips; Tines - breviglieri mbe-3 Manuel D'utilisation Et D'entretien

4.6.1 HOW TO WORK

Engage the power take-off and move forwards with the tractor while progressively lowering the machine. Drive a short way then
check to make sure that the work depth, the extent to which the soil is broken up and the soil levelling process are correct. For
increased adherence to the ground, adjust the compression of the spring by means of the relative ring nut.

4.6.2 USEFUL TIPS

Depth too shallow
▪
Check the way the tilling units are regulated.
▪
Advance more slowly. The tractor power could be insufficient.
▪
Further runs are needed if the soil is too hard.
▪
The tines roll over the soil instead of penetrating it: advance more slowly.
Soil broken up too much
▪
Increase the ground speed.
Soil not broken up enough
▪
Reduce the ground speed.
▪
Do not work in soil that is too wet.
Rotor clogged
▪
Soil too wet to work.
▪
Lift the tilling unit.
▪
Reduce the ground speed.
▪
Do not work where the grass is too tall. If necessary, remove any material that has built up at the sides of the rotor to pre-
vent overheating.
The machine jolts over the ground or vibrates
▪
Foreign bodies blocked between the tines.
▪
Tines incorrectly mounted without the helical positioning or that penetrate into the soil with the blunt edge first.
▪
Worn or broken tines.
▪
The rotors have become warped due to striking obstructions during work.

4.7 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 imme-
diately 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 tilling blades are propeller shaped for normal and tenacious soils; the
cutting edge of the tilling blades must always point in the direction the rotor turns.
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.
If the tilling blades are replaced, cleaned or widened, remove the plug from the hole (1 Fig. 9) by taking out the safety split pin. Now
raise the blade using the relative handle on the casing and fit the plug and safety split pin into the hole (2 Fig. 9) in the support.
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 below.
If tines must be replaced, make sure that the new ones are mounted in the same positions as the old.

DANGER
Tine replacement is a dangerous operation.
