How to Troubleshoot a Horse Trailer

Horse trailers are practical for owners with one or two horses, but they require an annual safety check to keep them roadworthy. Common problems with trailers include lights not working, unsafe flooring, and issues with tires or hitches.



Carrying out a step-by-step check will help you troubleshoot any problems and identify any potential issues for the future.

Instructions

      Check the bodywork of the trailer. If you have a wooden floor, remove any rubber matting and check the edges of the floor. For an aluminum floor, check for areas of corrosion. Use a screwdriver to probe any unsafe areas. Any problems with the floor must be rectified immediately as it could potentially break under your horse's weight.

      Slide underneath the trailer. Use a wire brush to clean any areas of rust, and wash off caked mud. Any patches of corrosion should be welded.

      Check the tires. Many horse trailers are used infrequently and the tires rot before they deflate. Low pressure in the tires will cause wear and tear on the trailer and an uncomfortable ride for your horse.

      You will also use more fuel in towing the trailer. Check the manufacturer's handbook for the correct tire pressures, and replace any damaged tires. Take care that all four tires are inflated to the same level.

      Check the lights. With the trailer hitched to your vehicle, get someone to help you check the indicator and brake lights. Replace any bulbs if necessary. If any lights are still not working, get the wiring checked professionally.

      Examine the hitch, and make sure there is no corrosion. Apply a coat of grease for protection.

      Finally, check and grease any clips and hinges, making a note of any wear and tear.
