A lift and support structure is provided for a lawn tractor which includes a frame with a center lift member secured to and separating a pair of wheel support members. Ramps are secured to the wheel support members to permit the front or rear wheels of the lawn tractor to be rolled onto or off of the lift and support structure. The center lift member is elevated above the wheel support members to permit a floor jack or other lifting mechanisms to be placed under the lift and support structure. A pair of support legs may be locked in a raised position to support the lawn tractor for safe and easy access to the underneath side of the tractor, and may be pivoted or folded to the side when the lift and support structure is in a lowered position.

A building construction system is provided having an elongated track (bypass clip track) that overlays a front edge of a concrete slab. The elongated track provides an even flat surface along an uneven concrete slab because the elongated track can be placed at adjustable distances from slab edges that may be uneven. The track is secured to a bracketing structure that has foam inserts that become embedded within the top and / or bottom surface of the concrete slab after the concrete hardens. By attaching the track to these foam inserts instead of the concrete directly, breakage or spalling of the slab edge is reduced. Studs are then attached to a stud attachment plate extending from the track, such that thereafter, a wall or façade may be attached to the track that overlays the uneven slab edge.

A modular wheel lift provides elevation of a vehicle wheel enclosed by body portions of a low height above the ground. A base lift unit includes a lift surface height selected to be less than the body portions height. A ramp unit is aligned and hingedly attached to one end of the base lift unit, to allow rotational movement of a wheel to the base lift surface. Additional lift units having ramp ends and progressively decreasing lengths are laterally positioned and stacked on the base lift surface. Side brackets are releasably positioned along either side surface to secure the stacked additional lift units to allow rotational movement of the vehicle wheel to an uppermost lift surface. A method of assembly and elevating includes laterally positioning and stacking a plurality of lift units having progressively shorter lengths to provide lifting of a vehicle wheel without disruption of the vehicle body portions.

A portable ramp system 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 The ramps may be stowed in a holder secured to the equipment deck. Magnets may be included in a bottom portion of the ramp to provide an optional means for stowing the ramps on the equipment.

A leveling device for vehicle wheels comprising a first integral planar member for mating with one or more additional integral planar members of substantially the same shape and dimension in releasable relationship. All integral members have four sides and an upper surface divided into a plurality of vertically projecting rows of pins with a row of projections situated up front. The bottom surface of each of the integral planar members include rows of sockets, each of which is conformable in shape and size to receive an individual pin in releasable frictional engagement. Each planar member also includes one partially beveled side with a sloped projection with one or more openings conformable to the shape and dimensions of the individual pins. Two or more integral planar members are adapted to stack one upon the other by mating pins and sockets of respective planar members so that the sloped projections overlap one another and are positioned in parallel relation. The sloped projections of stacked planar members may also be disposed in a laterally offset relation. Both embodiments enable substantial alignment of the inclined planes to facilitate movement of a vehicle wheel up on to the surface of the device and back down.
