  • Patent number: 8136334
    Abstract: A reel mower cutting unit having a cutting reel with a horizontal axis is supported by a front roller and a rear roller in a mowing position. A lift arm may raise and lower the cutting reel between a mowing position and a transport position. A pair of gauge wheels are mounted forwardly of the front roller at a front left corner and a right front corner of the unit. If the unit is lowered to a sloped surface, the gauge wheel contacts the surface and prevents the unit from marking or damaging the turf.

  • Publication number: 20120017559
    Abstract: 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. A driven member has a driven shaft rotatably supported in the frame about the shaft axis, and a driven face. A projection 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 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 projection from the recess. A height adjustment mechanism moves ground rollers closer together or farther apart to vary cutting height.

  • Patent number: 8042321
    Abstract: 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.

  • Publication number: 20110185691
    Abstract: A reel cutting unit of a reel mower is provided with a belt and pulley drive system for rotating the reel of the cutting unit at variable speeds when the ground speed of the reel cutting unit is substantially constant to provide different clips. The drive system has three pulleys of different diameter in engagement with the belt in drive, driven and idler positions. The pulleys can be interchangeably used in any of the positions by moving the pulleys around into the different positions in six different possible arrangements. The pulleys are selectively placed in one arrangement at a time to select the clip provided by that arrangement. A chain and sprocket drive system with different diameter sprockets may be used in place of the belt and pulley drive system. The belt and pulley drive system may comprise toothed pulleys and toothed timing belt.

  • Patent number: 7971421
    Abstract: A walk reel mower includes a pair of inclined rigid links for mounting the reel cutting unit to the reel mower frame for rolling about a longitudinal axis, and a pair of vertical support arms for mounting the reel cutting unit to the reel mower frame for pitching about a transverse axis. An integrated gearbox houses both the traction and reel drives, including the differential that is part of the traction drive, as well as a parking brake. A flexible drive shaft powers the cutting reel from the gearbox and is made from materials that do not require petroleum based lubricants to avoid the possibility of damage to the turf or grass. A single control handle located on the handle of the mower actuates both the reel and traction drives. The reel cutting unit includes a back plate which has a portion formed as a hollow beam for strength.
