ABSTRACT:
A U-shaped trailer frame is supported above the ground on wheels and includes a U-shaped sub-frame pivotally connected thereto for pivotal movement between raised and lowered positions with the front end of the sub-frame engaging the ground in the lower position and the rear end engaging the ground in the raised position. The snowmobile is loaded onto the trailer by pivoting the sub-frame to the down position and then driving the snowmobile into the sub-frame with the front end being supported on a bottom wall sub-frame portion. The sub-frame and snowmobile are then pivoted to the up position and a support member is moved under the snowmobile to support the rear end of the snowmobile on the sub-frame when the sub-frame and snowmobile are pivoted to a horizontal position for transport. Alternatively, one or more sub-frames may be carried on a trailer frame for loading and transporting more than one snowmobile.
