Abstract: A trim mower includes a frame supported by a plurality of wheels to travel over a ground surface, at least two front reel-type cutting units and at least one rear reel-type cutting unit. A separate lift arm is attached between the frame and each reel-type cutting unit. Each lift arm can pivot to move a reel-type cutting unit between a mowing position on a ground surface and a transport position raised above the ground surface. The lift arm for at least two of the cutting units, and preferably at least one front cutting unit and one rear cutting unit, can extend to selectively move the cutting units attached thereto laterally while the cutting units are in the mowing position. The lateral movement of a front cutting unit may be proportionately further than the lateral movement of a rear cutting unit.
