Combination of tractor and mounted implement
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
