...................(for calculating the ballast)
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
4.4 COMBI MACHINE WITH SEED DRILL
CAUTION
While working with power harrow in combination with seed drill machine both the pins and tractors linkages must be of 3rd.
cat. in all different working widths.
Be very careful when coupling the machine with a seeder and in the case of rear installation
of hydraulic seeder couplings. Each hydraulic seed drill coupling supplied with the machine or at a later date on the Customer’s
request, has a serial number and instruction manual where
all the specifications for assembly and use are given. In the
event however of the seeder coupling being fitted by the
end user, remember to:
▪
Once the frame has been mounted on the ma -
chine, in order to raise the seed drill with the seeds, the
overall weight of the combination must not exceed the
value given in the operation and maintenance manual.
▪
Make sure that the seed drill is correctly
mounted, that it lifts in the right way and that nothing
interferes with the hydraulic pipes.
▪
Make sure that the mechanical parts of the seed
drill do not interfere with the roller of the machine or
with the machine itself.
▪
Make sure that when you drive along the public
roads, there are no sharp parts that project from the
sides of the machine.
▪
Make sure that the relative signs are clearly
visible behind the combi machine. If this is not the case,
proceed as required by the Highway Code regulations in
force in the country where the machine is used.
IMPORTANT
When transporting on public highways, the seeder hopper must always be completely empty.
