in the soil. Do not work in reverse. Always raise the implement before you change direction or reverse. During transport or
whenever the machine must be lifted, remember to adjust the power lift of the tractor so that the steerage hoe is not raised
more than about 40 cm from the ground. Do not drive on the public roads with the machine caked with soil, grass or other
materials that could dirty the road surface or hamper the traffic in any way. Do not allow the machine to drop violently on
to the ground. Lower it slowly to allow the tines to gradually penetrate into the soil otherwise all the machine components
would be subjected to stress that could lead to breakages.

4.4 TRANSPORT POSITION

The following expressions must be observed to ensure that the tractor-machine assembly is stable (Fig.24):
M < 0,3T
................................................................. (prudential value)
Z > {[(M x s) – (0,2T x i)] / (d x i)}
where:
i = tractor's wheelbase
d = horizontal distance between the center of gravity of the front ballast and the tractor's front axle
s = horizontal distance between the center of gravity of the machine and the tractor's rear axle
T = weight of the tractor in running order
Z = ballast weight
M = weight of the machine

4.5 WORK DEPTH

The machine's work depth is established by operating the crank that controls the vertical movement of the two wheels (A Fig. 7).
The crank must then be retained with the relative fork. Max work depth 10 cm in loose soil.

4.5.1 ADHERENCE ADJUSTMENT WHEN TILLING

To adjust the tilling unit's adherence to the ground, regulate the compression of the spring by means of the relative ring nut: turn
the nut towards the left to reduce the adherence or towards the right to increase it (Fig. 8). Along with the adherence adjustment,
you can also increase or reduce the extent to which the tilling unit slants in relation to the ground by means of the relative crank
above the spring. Turn towards the right to raise the rear part or towards the left to lower it.

4.6 IN WORK

Begin work with the PTO at full rate. Gradually dig the implement into the ground. Do not depress the accelerator pedal too much
with the PTO engaged.To break up the soil to the required degree, you must consider several factors, i.e.:
▪
the nature of the soil (medium consistency, sandy, clayey, etc.)
▪
the work depth
▪
the ground speed of the tractor
▪
optimum machine adjustment
The soil is crumbled to a fine degree with a low tractor ground speed and with the tilling unit close to the ground.
The speed of the tractor when the machine is operation must not exceed 3-4 km/h or components could be broken or da-
maged.
The turning tines could throw up stones or other sharp materials as they work. Constantly check to make sure that there are
no bystanders, children or domestic animals within the range of action of the machine.
