Operating unit joint for turf maintenance equipment

摘要

A steering operating unit joint (22) for connecting an operating unit (20) to a lift arm (18) of a turf maintenance machine (10). Operating unit (20) can be a reel-type turf cutting unit. Cutting unit joint (22) preferably includes a pivot knuckle (50) having a snout (66), suitably secured to the free end of lift arm (18); and a snout receiver (94) suitably secured to cutting unit (20). A pair of resilient elements (100) is interposed between snout (66) and snout receiver (94). Elements (100) act between snout (66) and snout receiver (94) to resist "yawing" of cutting unit (20), whereby cutting unit (20) can be automatically straightened once it is raised to its transport position. During transport, cutting unit (20) is maintained in a straight and level orientation so that the turf is not gouged when the cutting unit (20) is lowered to its operating position "on the fly.
