4.7.2 USEFUL ADVICE

Depth too shallow
- Check the depth adjustment.
- Move forward more slowly. There may be insufficient tractor
power. Raise the rear roller.
- Further runs will be required if the soil is too hard.
- The blades slide over the ground instead of digging into the
soil: advance more slowly.
Soil crumbled too finely
- Lower the speed of the blade rotors.
- Increase the tractor ground speed.
Soil insufficiently worked
- Increase the speed of the blade rotors.
- Reduce the ground speed.
- Do not work if the soil is too wet.
- If the levelling bar is installed, try lifting or lowering it.
Clogged rotors
- Soil to wet to work.
- Raise the levelling bar.
- Reduce the ground speed.
- Do not work where the grass is too tall.
The machine jolts over the ground or vibrates
- Foreign bodies locked between the blades.
- Blades incorrectly mounted in the wrong positions.
- Worn or broken blades.
- Blades bent during work after hitting stones or having worked
excessively hard soil.
The machine vibrates too much
- Reduce the ground speed of the tractor.
- Adjust the machine in the correct way, as described in the in-
structions.
- Clean the rotors. They could be clogged.
- Check whether any blades are broken. Replace them if this is
the case.
The rotors turn in an uneven way
- Make sure that the driveline clutch is regulated correctly.
- Excessively elastic clutch springs. Replace the springs.
The gearboxes overheat
- Check the oil level and top up if necessary.
The driveline clutch overheats
- Check the clutch plates for wear. Have them replaced by an
authorized workshop if necessary.
- Excessively elastic clutch springs. Replace the springs.

4.8 TINES

The blades fitted on the implement are suitable for soil of a nor-
mal consistency. Check them daily to make sure that they are in a
good condition and not worn. If the blades should accidentally
bend (or break) during work, they must be immediately replaced.
Make sure that the new blades are mounted in exactly the same
positions as the old ones.
If several blades must be replaced, it is advisable to demount and
remount them one at a time in order to avoid positioning errors.
The sharp side of the blades must point towards the direction in
which the blade rotor turns.
Blade replacement is a dangerous operation.
Proceed in the following way to change the blades:
- 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 blades must be changed, make sure that the new ones are
mounted in the same positions as the old ones.

If the tines 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.
4.9 GEARBOX (mekfarmer 100)
The tine rotors can spin at various speeds, depending on the gear
pairs mounted in the gearbox. It also allows the soil to be broken
up to various degrees depending on its nature, the amount of
moisture it contains, the ground speed, etc.
Only use the pairs indicated in the table

The faster the rotors spin, the more the soil is crumbled, but trac-
tor power draw and blade wear will also be greater.
You are advised to use the lowest rotation speed able to work the
soil in the required way.
Carry out these simple operations in both gearboxes to vary the
speed of the rotors:
- Remove the screws that fix the rear cover of the gearbox (5 Fig.
1) and take off the cover. Take care, as oil could spill out.
- Remove the gears from the shafts.
- Fit the required pairs of gears on to the shafts.
- Fit back the cover and re-tighten the screws.
Make sure you use the right gears as gears of different pairs can-
not be mounted.
