Abstract

A self-propelled dump trailer comprises a frame, a first wheel driven by an engine, a second wheel, a steering mechanism, and a dump bed that may have its front end elevated by a lifting mechanism. The frame includes a coupler so the dump trailer can be selectively coupled to a vehicle and uncoupled from the vehicle. Further, the dump bed includes a rear gate and a separator gate that divides the dump bed into two sections, wherein the separator gate is operable to place the dump bed into a first dumping position and a second dumping position. As such, the forward section of the dump bed acts as a counterbalance during a dumping operation.
