Combination of tractor and mounted implement
DANgER
Life hazard or material hazard - due to overload on tractor or wrong tractor ballast distribution.
•
Make sure that hitching the implement (in the front and rear three-point linkage) does not lead to exceeding the maximum
total admissible weight of the tractor, the axle loads or the load capacity of the tyres. 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.
see instruction handbook of the tractor
see price list and/or instruction handbook of the implement
to be measured
