Connections; Check The Raising Ability Of The Tractor - Cosmo PDC 400 Manual De Uso

4. CONNECTIONS

The machine can be delivered all assembled or not (in this case follow the assembling instructions
enclosed). In both cases, before using the spreader it is necessary to control that all the fixing elements
(screws, nuts, washers) are well locked and make sure that all the safety devices are located at their right
position.
Verify that the gear box is fixed to the machine frame by 4 screws: two longer (Hexagonal head 12x50)
in the front part, at the Pto shaft connection side, and two shorter (hexagonal head 12x40) back, at the
pendulum side.
Before coupling the machine to the 3-point hitch, positioning the safety devices to the tractor, so that it is
not possible the involuntary and/or accidental raising and lowering of the arms.
The 3-point hitch of the tractor and of the machine must coincide or must be adapted.
In proximity of arms rods of the back lifter of the tractor, there is the danger of wounding, because of
crushing and cutting points.
Do not use the external controls for the lifting of the machine. During transport position block the lateral
stop of the rods.

CHECK THE RAISING ABILITY OF THE TRACTOR

Check the raising ability and the stability of the tractor through the following formula and if it
is necessary please apply some ballasts on the back.
Pendular Spreader PDV - PDHV models
DANGER!
It is obligatory to check the raising ability and the stability of the tractor (before
carrying out the connection with the machine) in order to avoid the overturning
and/or the loss of wheels grip.
M s ≤ 0,2 T i + Z (d + i)
M ≤ 0,3 T
i = Wheels base of the tractor
d = Distance of load ballast back axle
s = Bounce of the machine rear axle
T = Tractor load + 75 kg (operator)
Z = Load ballast
M = Machine load
