A bedknife assembly for a reel mower cutting unit (100) includes a cutting reel (106) rotatably mounted to a frame, and a bedknife (110) mounted to a bedknife support (116) pivotally mounted to the frame in either a first position having a first pivot axis (148) closer to the ground surface, or a second position having a second pivot axis (149) further from the ground surface. The first pivot axis (148) is further from the central axis (108) of the cutting reel (106) than the second pivot axis (149) is from the central axis (108). The adjustable pivot axis may include a pair of eccentric pivot bushings (152, 153) mounted to the frame in either the first position or the second position. The adjustable pivot axis permits adjustment of the reel-to-bedknife gap after the reel (106) is worn and its diameter is reduced, without dragging the bedknife (110) on the turf, and extends the useful life of a cutting reel (106) by increasing the adjustment range of the bedknife assembly.
