The lift arms are configured such that when in an extended position rear step ends of the lift arms are located rearward of the outer rim of the rear wheel, and the front ends are located generally forward of the outer rim of the rear wheel. A front lift mechanism provides a lift lever operative to push a lift wheel downward to raise the front caster wheels of the wheelchair.
