6) Besides supporting the Levelling bonnet and acting as a shock absorber for it during road transport, the spring
ram (Fig. 10) prevents the steerage hoe from overturning when parking. The effect of the levelling bonnet on the
soil can be increased or decreased depending on the position, established by the split pin, Nut and bolts (Fig.
10) in the various holes in the ram tube ( Fig. 10).

3.5 CHECK THE LIFTING CAPACITY AND STABILITY OF THE TRACTOR TO
WHICH THE MACHINE IS HITCHED
Assembly of a implement on the tractor will shift the weights on the axles (Fig.11).
It is there fore advisable to add weights to the front part of the tractor in order to balance the weights on the axles
themselves.
The ballast required is calculated by means of the following formula:
Z > M x S - 0.2 x T x i
d + i
S = S1 + S2
If the implement is hitched to approved agricultural tractors registered before 6th May 1997, also check to make
sure that the following relation has been complied with:
M < 0.3 x T
I = Tractor wheelbase (cm).
d = Distance between front axle and center of gravity of ballast (cm).
T = Weight of tractor + operator (75 kg)
Z = Weight of ballast (kg)
M = Weight of implement (kg)
