A load frame which mounts on a trailer between the trailer hitch connection and the trailer frame front cross member. The load frame is a wishbone-shaped structural unit which mounts to the trailer frame front cross member with a pivoting saddle on the two rear legs of the wishbone. The load frame includes a spindle mount connected to a wheel assembly and a retracting arm for engaging a retracting apparatus to adjust the relationship between the wheel assembly and the trailer frame. The spindle mount includes a suspension mechanism and a pivoting connection for the wheel assembly. The wheel assembly includes a spindle member which is slidably and rotatably attached to the spindle mount. A tire is rotatably attached to the wheel assembly. The tire extends downwardly from the spindle mount to roll along the ground and support a portion of the tongue weight of the trailer.
