3.6 Axle load

The attachment of implements to the front- and rear-three point
linkage must not lead to exceeding the allowed total weight, the
allowed axle load and the allowed tyre load of the tractor.
The tractor front axle must always be loaded with 20 % of the
tractor dead weight at minimum.
How to calculate the minimum front ballast and the increasing of the rear axle
load, is described in detail as follows:
G = Weigth of front ballast (front implement)
V
T = Front axle load of the tractor without mounted implement
V
T = Tractor dead weight
L
T = Rear axle load of the tractor without mounted implement
H
G = Weight of the implement combination
