ABSTRACT:
A lawn tractor includes a vehicle body, a center reel-type cutting unit, and side reel-type cutting units arranged laterally of the center reel-type cutting unit with respect to a moving direction of the vehicle body, wherein a cutting track by the center reel-type cutting unit and cutting tracks by the side reel-type cutting units partly overlap one another. A first lift mechanism vertically movably connects the center reel-type cutting unit to the vehicle body, wherein the first lift mechanism is operable to raise and lower the center reel-type cutting unit without displacing the center reel-type cutting unit transversely of the moving direction. Second lift mechanisms vertically movably connect the side reel-type cutting units to the vehicle body, respectively, wherein the second lift mechanisms are operable to raise and lower the side reel-type cutting units without displacing the side reel-type cutting units transversely of the moving direction.
