Optimum machine adjustment.
Soil crumbling is obtained at a low tractor ground speed, with the rear bar lowered and the blades spinning at 300 rpm. Besides
holding back the clods already broken up by the blades, the rear bar also obtains a well levelled and uniform surface after the soil
has been worked.
4.4.1 HOW TO WORK
Adjust the roller (2 Fig. 1) to suit the degree to which the soil must be crumbled, engage the PTO and begin to move forward
with the tractor, progressively lowering the implement. Cover a short distance, then check to make sure that the work depth, soil
crumbling and ground levelling operations have been carried out in the required way.
The speed of the tractor when the machine is operation must not exceed 6-8 kph or components could be broken or damaged.
The blades may throw up stones or other sharp objects as they spin. Constantly check to make sure that there are no bystan-
ders, children or domestic animals within the range of action of the machine.

4.4.2 WORK DEPTH ADJUSTMENT

Depending on the way the implement is outfitted, the work depth of the folding harrow can be adjusted:
with hydraulically controlled cylinders (2 Fig. 1).
Raise the roller to dig deeper into the soil. Lower the roller if the work depth must be more shallow. Work depth adjustment with
the hydraulically controlled cylinders is carried out from the driving position by means of a hydraulic actuator that controls the
two hydraulic cylinders (2 Fig. 1). These cylinders regulate the rear rollers (1 Fig. 1) and therefore determine the work depth. Both
hydraulic cylinders have a blocking valve that allows the same roller adjustment and, thus, the same tilling depth to be obtained.
4.4.3 USEFUL TIPS
Here are a few useful suggestions on how to resolve some of the problems that may occur during work.
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 instructions.
Clean the rotors. They could be clogged.
Check whether any blades are broken. Replace them if this is the case.
