Used Dump Trailers — what to check

A used dump trailer lives or dies on its hydraulics and hinges: run the bed up and down several times, watch for slow drift (a leaking cylinder or seal), and inspect the pump, battery, and wiring. Check the pivot pins and the bed floor for cracks or heavy denting, confirm the barn/spreader gate latches, and verify the brakes work on a loaded pull. Ask the battery's age.
