Abstract: A jack stand for lifting and supporting a snowmobile which comprises a base frame, preferably on wheels, a front elevating post and two rear elevating posts pivotably attached to the base frame, and a linkage assembly connected to the elevating posts such that the elevating posts all move simultaneously and remain parallel to one another when the elevating posts are pivoted between an elevated position whereat the elevating posts are substantially vertical and a collapsed position whereat the elevating posts are substantially horizontal. The elevating posts each have an outer end constructed and arranged to interface with a portion of the snowmobile. The jack stand also preferably has a latching mechanism that locks the jack stand in its elevated position, and a lever bar selectively attachable to the front post for aiding in moving the jack stand between its collapsed position and its elevated position.
