A lifting apparatus which engages and lifts the rear end of a snowmobile and provides a method of locking the snowmobile in an elevated position by the use of a retaining pin. The base of the apparatus consists of a ground engaging frame having a perpendicularly attached and vertically extending section that supports a wide shield. The purpose of this shield is to protect users and bystanders from ice, dirt and snow that is ejected out from under the snowmobile. The lifting mechanism consists of a vertically adjustable snowmobile engaging post. This post is connected to a lifting plate which travels vertically along a center frame member. The plate engages the center frame member with a pair of rollers, one roller in front of the frame member and a second behind. A curved pivot lift bar is attached to the lifting plate and extends upward to a center pivot arm that is pivotally connected to the center frame member. The center pivot arm also has fixedly attached a lift lever. The center pivot arm may be locked against the curved pivot lift bar with a retaining pin, thus holding the lift in an upright position.
