Patent number: 8042321Abstract: A rotating mechanical apparatus, such as would be used in a reel mower assembly, comprises a drive member rotatably mounted in a frame about a shaft axis. The drive member has a drive face oriented perpendicular to the shaft axis. A driven member has a driven shaft rotatably supported in the frame about the shaft axis, and a driven face oriented parallel to and bearing against the drive face. A bulb extends outward from one of the drive face and the driven face and into a corresponding recess in the other. Magnets force the drive face to bear against the driven face such that the driven shaft rotates with the drive member. One of the drive face and the driven face are movable along the shaft axis to disengage the bulb from the recess. A height adjustment mechanism moves ground rollers closer together or farther apart to vary cutting height.Type: GrantFiled: October 2, 2006Date of Patent: October 25, 2011Inventor: Jeffrey Buchko

Publication number: 20090223191Abstract: The mechanical interlock prevents inadvertent engagement of a control member. Rotation of the mechanical interlock about an interlock axis from a locked position to an engagement position allows the control member to rotate about a control axis. The mechanical interlock includes an interlock bracket that defines a guide path having locking and actuating segments that intersect at an acute angle, and a guide member that engages the guide path. One of the interlock bracket or the guide member is pivotally coupled to the control member about the interlock axis and the other is coupled to a handle. The guide path and the guide member are selectively positionable between a locked position where the guide member is proximate the locking segment, an engaged position where the guide member is proximate the intersection, and an actuated position where the guide member is proximate the actuating segment.Type: ApplicationFiled: March 10, 2008Publication date: September 10, 2009Inventor: Grant Thomas Wilson
