Claim:
1. A powered wheelchair comprising: a frame; a seat; a lift mechanism coupled to the seat, the lift mechanism configured to move the seat from a lowered position to a raised position; a pair of drive wheels; at least one drive coupled to the frame and configured to apply a torque to at least one of the drive wheels; an arm assembly including an arm member that is pivotably coupled to the frame and a wheel assembly rotatably coupled to the arm member proximate a distal end of the arm member, the arm member being operatively configured to be in a first position relative to the frame when the powered wheelchair is operating on flat ground and to be rotatable from that first position; and an arm limiter supported by the frame and configured to inhibit motion of the arm member, the arm limiter having a first configuration in which the arm member is rotatable from its first position through a first range of rotation, and a second configuration in which the arm member is rotatable from its first position only through a second range of rotation that is smaller than the first range of rotation, provided that the arm limiter is prevented from transitioning into the second configuration when the arm member is rotationally different from its first position relative to the frame by more than 4 degrees.
