Trailer Drawbar Connection
Attaching the trailer to the tractor from the drawbar or the tow hook fixed to the body, not from the three-point linkage. Because the hitch point is close to the axle centre and low, the drawbar force does not produce a moment trying to tip the tractor backwards; a trailer attached to the linkage removes this safety.
The risk of overturning arises from geometry. The higher the hitch point is taken, the greater the overturning moment the drawbar force creates about the rear axle. The three-point linkage is high and mobile; it is also not designed to carry a high vertical load continuously.
- A trailer is always attached to the drawbar or to a tow hook approved by the manufacturer.
- Keep the drawbar height within the range stated by the manufacturer.
- On a braked trailer, connect the brake line every time and do not forget the safety chain.
An electronic retrofit kit does not change this rule. The LFT20, LFT54 or ELF-812 lets you control the linkage electronically; it does not change the linkage's carrying limits or the towing geometry. Towing a trailer is done only from the drawbar on a tractor with a kit fitted as well.
