A drive across low-profile portable hydraulic trailer dumper for dumping the contents from a trailer containing a dumpable material, includes a towable elongated frame. A base frame with a deck pivotally attached hereto, which closes down and interlocks with the base frame. Making the overall height of the lift deck only seven (7) inches above the ground or pad site. Removable tread plates for use, when pulling a tractor and trailer forward, onto the trailer dumper. The lift deck has an adjustable chock for positioning the trailer during dumping. Actuators raise and lower the deck between a lowered position adjacent the base frame and a raised position for dumping the trailer contents. The trailer dumper has opposing cantilever wheels located near the back end of the dump for lowering a back end base frame to the support surface at the dump site, and raising a back end of a trailer dumper for towing. The low-profile trailer dumper has telescoping stabilizers located inside the base frame, and positioned under the deck lift actuators. Actuators located near the front of the base frame, lift and lower a front end of the frame between a low-profile dumping position for receiving the trailer and a raised towing position for hitching and towing the trailer dumper, from first dump location to a second dump location. A method of successively removing the contents from a plurality of trailers using the trailer dumper is also provided.
