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.
