ABSTRACT:
A motorized snow vehicle stand, for supporting the rear of the vehicle in a raised parking position so that the endless drive track is elevated above the ground, including a bail carried on a transverse horizontal pivot bar extended across the rear of the vehicle and rotatable through an arc of more than 180.degree. from a raised or upright inoperate position where it is normally held against the rear of the vehicle by a manually releasable hook to a fully operative vehicle supporting position in engagement with the ground under the raised rear end of the vehicle where it is disposed in inclined position forward of dead center. The pivot bar is mounted on the vehicle in releasable nonrotatable relation and a spring is biased between the pivot bar and the bail, with provision for releasing and turning the bar to vary the spring tension. On release of the holding hook, the bail swings in two stages under action of the spring, namely through a first arc of less than 180.degree. to engage the ground behind the vehicle and subsequently through a further arc when the vehicle is lifted allowing the bail to swing under the vehicle into an inclined position beyond or forward of dead center.
