Abstract
A trailer for a walk greensmower comprises a trailer frame supported by a pair of ground engaging trailer wheels. The trailer frame includes a pair of spaced, parallel wheel ramps. A tongue is provided for connecting to a tow vehicle. The trailer frame is pivotal relative to the tongue and to the trailer wheels to tilt into an inclined loading position for loading the walk greensmower by driving the walk greensmower up the wheel ramps using the powered transport wheels of the walk greensmower. Once the walk greensmower is loaded onto the wheel ramps, the trailer frame is pivoted into a transport position in which the wheel ramps no longer engage the ground and the walk greensmower is carried on the wheel ramps. In one embodiment of this trailer, the wheel ramps comprise cylindrical rails and the transport wheels are grooved to ride on the top sides of the rails.
