摘要： A portable ramp made according to this invention includes a pair of interconnected ramps for use with high-centering wheeled lawn equipment such as commercial walk-behind mowers. The ramps allow the equipment to move between a first lower elevation and a second higher elevation without its front wheels becoming airborne as the equipment traverses the ramps in a forward direction. The ramps are connected to one another by a flexible tether that allows the distance between the ramps to be easily adjusted and provides a means for stowing the ramps over the handles of the equipment Magnets may be included in a bottom portion of the ramp to provide an optional means for stowing the ramps on the equipment.
