Operating the attachments

Additional information for attachments

When installing attachments on the front and
rear lift arms, do not exceed the permissible to-
tal weight, the maximum allowable axle loads
and tire carrying capacities of the tractor. The
front axle of the tractor must always be loaded
with at least 20 % of the tractor’s curb weight.
Before purchasing any equipment, make sure
these conditions are met by performing the fol-
lowing calculations or by weighing the tractor-
equipment combinations.
Determination of the total weight, axle loads and tire
load capacity including minimum ballasting
For the calculation you need the following data:
TL(kg) Curb weight of the tractor1)
TV(kg) Fro nt axle load of the empty tractor1)
TH(kg) Rear axle load of the empty tractor1)
GH(kg) Total weight of
rear attachment/rear ballast 2)
GV(kg) Total weight of
front attachment/front ballast 2)
