Patent ID: 8225587

Claim:
A turf cutting unit comprising: a frame; a reel assembly mounted to the frame and having a plurality of blades rotatable about a reel axis extending substantially parallel to the ground; a rotatably driven groomer including a plurality of spaced apart and substantially vertically oriented cutting plates; and an adjustment assembly connected to the frame and operable to move the reel assembly relative to the turf to set a turf cutting height, the adjustment assembly having a roller bracket including an outboard plate, an inboard plate and a push plate fastenably and rotatably connected to the inboard plate, the outboard plate having an elongated slot extending along an arc having a center aligned with the reel axis, the slot guiding movement to adjust the position of the cutting plates to set a depth of cut that the groomer cutting plates engage the turf, the adjustment assembly including an adjustment mechanism, the adjustment mechanism limiting a maximum depth of cut of the groomer cutting plates based on the cutting height of the reel assembly; a groomer plate is selectively moved relative to the outboard plate during the depth of cut adjustment of the groomer cutting plates, an amount of relative movement between the groomer plate and the outboard plate is limited to define the magnitude of the depth of cut; and the adjustment assembly having a link including a second elongated slot enabling relative movement between the groomer plate and the outboard plate, a length of the second elongated slot determining the amount of relative movement between the groomer plate and the outboard plate.
