Claim:
An improved grass grooming reel carried on a frame of the mower by at least one support, wherein the improvement relates to at least one height adjuster for changing the height of the grooming reel relative to the ground, which comprises: (a) a rod connected to the support that carries the grooming reel; (b) a driver having a screw thread connection to the rod for making a fine adjustment of the grooming reel relative to the ground when the driver is rotated; (c) a rotary knob that is large enough to be gripped and turned by hand, the rotary knob having a cam connection to the mower frame for effecting a quick up/quick down adjustment of the grooming reel relative to the ground when the rotary knob is rotated by hand between first and second positions of the rotary knob; (d) wherein the driver is rotatable independently of the rotary knob such that the fine adjustment can be made by rotating the driver without rotating the rotary knob, and wherein the driver sits atop the rotary knob to be visible and easily accessible from above the rotary knob; and (e) a set of detents on the driver cooperable with a lock on the rotary knob for holding the driver in an adjusted position relative to the rotary knob.
