  • WALK REEL MOWER WITH A TELESCOPIC FLOATING HANDLE ASSEMBLY HAVING INTERCHANGEABLE HANDLES, IN SITU BACKLAPPING, A TRACTION BAIL, AND INTERCHANGEABLE REEL CUTTING UNITS
    Publication number: 20210321562
    Abstract: A walk reel mower has a traction frame that carries a telescopic handle assembly to accommodate users of different heights. A pivotal bail on the handle assembly allows the user to slip a traction clutch to temporarily slow the mower down when turning the mower around. The handle assembly has a resilient isolator that acts in shear to permit the traction frame of the mower to maintain the quality and the height of cut when operated by users having a heavy downpressure touch on the handle assembly. A fixed head reel cutting unit or a flex head reel cutting unit can be interchangeably carried on the traction frame using a common mount therefor. Backlapping can be accomplished in situ by using an idler wheel between a driven transport wheel and the reel of the cutting unit to reverse the direction of the reel.
