Abstract: A T-shaped frame including a cross member and a telescopic standard is provided with a tire-supporting cradle on one of the standard portions adjacent an upstanding tire-engaging post. A hydraulic cylinder with a bead-engaging tool on its outer free end is pivotally connected to the other telescopic frame member. Adjustment means is provided for angularly positioning the cylinder relative to the horizontal for the tool to engage the bead of a tire. Casters are provided at the corners of the T-shape frame.

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.
