Publication number: 20210195835Abstract: A walk reel mower has a pivotal rear traction drum that can be selectively disposed in two different mowing positions that allow a single mower to cut grass on golf course greens as well as tee boxes with no degradation in cutting or power performance. The reel cutting unit has a pivotal rear shield to allow the rear shield to be pivotally adjusted to maintain its radial spacing relative to the orbit of the reel at a desired amount as the reel diameter decreases due to wear. The ground speed of the walk reel mower is automatically slowed during turns of the mower by a mechanical cable assembly that links a user operable throttle control and throttle reducing control to a prime mover throttle. Finally, the leverage provided by the mower handle assembly when placed in a lowered position is used by the user to more easily deploy a kickstand.Type: ApplicationFiled: March 16, 2021Publication date: July 1, 2021Inventors: Gerald E. Goman, Robert D. Patton, Larry W. Schmidt
