Pottinger Landsberg TOP 620 N Notice D'utilisation page 46

The mounting of implements on the front or rear three point linkage shall not result in exceeding the maximum permissible
weight, the permissible axle loads and the tyre load carrying capacities ot the tractor. The front axle of the tractor must
always to be loaded with at least 20 % of the unladen weight of the tractor.
Make sure before buying an implement that these conditions are fulfilled by carrying out the following calculations or by
weighing the tractor/implement combination.
Determination of the total weight, the axle loads, the tyre load carrying capacity and the
necessary minimum ballasting
For the calculation you need the following data:
T [kg] unladen weight of tractor
L
front axle load of unladen tractor
T [kg]
V
T [kg] rear axle load of unladen tractor
H
G [kg] combined weight of rear mounted implement/rear
H
ballast
G [kg] combined weight of front mounted implement/front
V
ballast

Consideration of rear mounted implement and front/rear combinations
1. CALCULATION OF MINIMUM BALLASTING AT THE FRONT G
Record the calculated minimum ballasting which is needed at the front of the tractor into the table.
Front mounted implement
2. CALCULATION OF THE MINIMUM G
Record the calculated minimum ballasting which is needed at the rear of the tractor into the table.
