ABSTRACT:
A lift for raising or tilting a small vehicle such as a riding lawn mower is disclosed including first and second ramps. The ramps each include an angled portion connected to a horizontal portion in turn connected to a vertical portion. The ramps are held by legs which extend from the vertical portion and which in the preferred form are removably pivotably mounted for ease of assembly and storage. T-shaped levers are pivotally mounted to the upper free ends of the vertical portions and generally include a first bar having a first end pivotably mounted to the ramps and a second bar having a first end conntected to the first bar intermediate its ends. In the most preferred form, the levers are pivotably mounted to the ramps by a cylindrical bar rotatably and slideably received in collars formed on the levers and ramps, with the cylindrical bar also holding the ramps in a spaced, parallel relation. Straps interconnect the free ends of the first bars of the levers with the vehicle. Thus, as the levers are pivoted from a position where the first bar is generally horizontal to a central position, the vehicle is pulled by a force directed forward and up and as the levers are pivoted from the central position to an overcenter position, the vehicle is pulled with a force directed forward and downward.
