A portable, user configurable service stand for a variety of riding lawnmowers and other motorized implements. The stand comprises a rigid frame with an elongated, longitudinal section spanning between twin, spaced apart vertical frame sections that support the load. Each vertical frame section secures generally planar, horizontal wheel supports. A pair of parallel, removable spans is coupled between front and rear wheel supports to temporarily provide a travel pathway over the stand. Removable, drive-on ramps are pivotally connected to the frame. After a mower is parked on the stand, the spans may be slidably removed, exposing the sides and undercarriage of the mower for convenient access. Upon removal of the spans, a pair of gravity-operated safeties automatically deploys to block the mower front wheels.
