Abstract
A mechanism coupling a yoke and cutting unit to a push arm, and having an upright steering pivot mechanism which establishes a relatively large effective steering lever arm for decreasing scuffing of the turf by the rollers of the cutting units, and an inclined pivot mechanism having an axis which is directed generally toward the cutting unit to decrease the effective lever arm between the rollers and the pivot axis and thereby reduce turf scuffing during execution of turns during mowing operations.
