Check the Trailer and Tractor Combination
A farm trailer can be mechanically sound and still become dangerous because a coupling is worn, a load has shifted or the tractor is not suited to the combination. Before leaving the yard, check the hitch and locking mechanism, safety connection where fitted, tyres, wheel fixings, lights, reflectors and the trailer’s braking system. Do not treat a handbrake or breakaway arrangement as a substitute for checking that the service brakes work as intended.
Secure the Load and Recheck It on the Route
Look at the load from the front, sides and rear. Heavy items should sit low and be distributed so the trailer remains stable and the tractor retains steering control. Use rated straps or chains attached to suitable anchor points; a loose net or rope is not automatically adequate restraint. Recheck the load after the first short distance, especially when carrying bales, machinery or material that can settle.
Follow the Rated Limits and Remove Defects from Service
The Health and Safety Authority’s tractor and machinery guidance covers safe operation and maintenance. The RSA’s Rules of the Road set out the road-user context, but the correct legal requirements depend on the trailer, vehicle and use. Do not infer a trailer’s permitted load from appearance: confirm its plated rating and the tractor’s operating limits. Keep a simple defect log and take a trailer with ineffective brakes, damaged tyres or a suspect hitch out of service until repaired.
For the tractor side of the combination, see our guide to tractor ballast and front-loader stability.
