Abstract
The invention is a driving assembly that can be attached to an existing trailer, manufactured with the trailer, or retrofitted onto a trailer in place of the front part of the trailer. The driving assembly comprises a housing attached to the trailer with a column disposed vertically through the housing. A cranking assembly engages the column and can vertically move the column. At least one drive wheel is attached to the column and is engageable with the ground. A hydraulic motor mounted on the wheel propels the trailer. A platform around the housing allows for the operator to be on the trailer while driving the trailer to impart weight to the drive wheel to increase traction.
