Additional information on implements
Do not exceed the permissible total weight,
the permissible axle loads and tire carrying
capacities of the vehicle when installing im-
plements on the front and rear 3-point lift. The
front axle of the vehicle must always be loaded
with at least 20 % of the vehicle’s kerb weight.
Before purchasing equipment, make sure these
conditions are met by performing the following
calculations or by weighing the vehicle-equip-
ment combinations.
Determining the total weight, axle loads and tire carry-
ing capacity including the minimum ballasting.
For their calculation you need the following data:
T

G
H
(kg) Total weight of
rear implement/rear ballast
2)

a (m) Clearance between centre of gravity
of front implement/front ballast and
centre of front axle
2) 3)
b (m) Vehicle wheelbase 1) 3)
