Abstract
A mechanism for adjusting the cutting height of a mower deck, which includes a four bar linkage with a pair of beam members, a rod member extending between the two beams. Rotation of the rod by the operator causes the beams to shift relative to each other, which causes the four bar linkage to raise or lower the mower deck. A projecting member is biased toward engagement with a detent formed in the rod member for securing the mower deck at the selected cutting height, and allows the operator to sense when the projecting member rides past the detent as the cutting height is incrementally adjusted.
