Abstract
An adjustment mechanism for reel-to-bedknife clearance includes an adjuster base having an internal bore, an adjustment knob attached to a rod extending through the internal bore to engage one of the reel or bedknife, and a detent spring captured between the adjuster base and the adjustment knob and biased against the adjustment member to resist rotation of the adjustment knob. The detent spring may engage radial notches on the adjustment knob at a plurality of reel-to-bedknife clearance positions.

An adjustment mechanism for reel-to-bedknife clearance, comprising:
- a rotatable adjustment knob having a plurality of radially directed notches;
- a rod having a first end connected to the adjustment knob;
- an adjuster base through which the rod extends, the adjuster base having a slot in a face thereof;
- a detent spring mounted within the slot and having an upturned end with a ridge that engages the notches at a plurality of different reel-to-bedknife clearance positions, the detent spring resisting rotation of the adjustment knob and held in place in the slot only by the adjustment knob and without any other fastener.

- an adjuster base having an internal bore;
- an adjustment knob attached to a rod extending through the internal bore to engage one of the reel or bedknife;
- a detent spring captured between the adjuster base and the adjustment knob and biased against the adjustment member to resist rotation of the adjustment knob;
- the detent spring held between the adjuster base and the adjustment knob without any other fastener.
An adjustment mechanism for reel-to-bedknife clearance, comprising:
- a bedknife having a cutting edge adjacent a rotating cutting reel having a plurality of cutting blades;
- an adjustment knob connected by a rod to one of the bedknife and the cutting reel;
- the adjustment knob rotatable to vary the clearance between the bedknife and cutting blades;
