ABSTRACT:
A rotary mower (10) including a front deck assembly (18) and a pair of wing decks (20). Each wing deck (20) is supported by a lift arm assembly including a main lift arm (26) and a lift arm extension (32). A pivot joint (30) exists between lift arms (26) and (32) so that when deck (20) is raised from its cutting position to its transport position it is also caused to rotate so that mower (10) maintains a relatively low profile even when decks (20) are in their transport position. Mower (10) also preferably includes a pair of breakaway assemblies (48) which allow wing decks (20) to "break away" in the event they strike an immovable object. Finally, a preferred mower (10) includes resilient bushing assemblies (38) between the wing deck lift arm assemblies and the wing deck housings (24) to minimize vibration and noise and provide some floating of the decks (20).
