Abstract: A grooming reel is carried on a greenmower between the front roller and the cutting reel. An improved adjustment unit is provided for changing the height of the grooming reel relative to the ground. The adjustment unit comprises an elongated rod connected to a support member on which the grooming reel is carried. A rotatable knob longitudinally draws the rod slightly along its axis to fine-tune the operating position of the grooming reel. In addition, the rod can be moved along its axis to raise and lower the grooming reel between an upper position and the operating position without disturbing the adjustment of the grooming reel in its operating position.
