Preconditions for the operation of tractors with rigid drawbar trailers
WARNING
Risk due to failure of components caused by incorrect use of the
tractor!
Ensure:
that the coupling device at the tractor has a sufficient admissible
tongue load rating for the actually existing tongue load.
that the coupling device at the tractor and the drawgear at the
rigid drawbar trailer are able to take up the towed load of the
rigid drawbar trailer (towed load = axle load). Calculate the
tractor’s admissible towing capacity if necessary.
that the tractor's axle loads and weights influenced by the
tongue load are within the admissible limits. Check the weight in
case of doubt.
that the static, actual rear-axle load of the tractor will not exceed
the admissible rear-axle load rating.
that the gross vehicle weight rating of the tractor will not be
exceeded.
that the admissible load-bearing capacities of the tyres mounted
on the tractor are not exceeded.
6.1.2.1 Combination options of coupling devices and drawgears
The following table shows admissible combination options of the tractor's coupling device and the
machine's drawgear depending on the maximum admissible tongue load.
The maximum admissible tongue load for your tractor is directly indicated on the type plate of the
coupling device/in the operating instructions/in the vehicle registration certificate of your tractor.
