Abstract
A mower deck height adjustment mechanism having a frame coupled to a rear base unit having driven wheels. Ground engaging wheels support the frame, and a deck is coupled to the frame. A crank handle is coupled to a transverse bar that is fixed to a lower parallel member. The operator turns the crank handle to pivot the bar and lower parallel member to thereby raise and lower the front of the deck. A bell crank couples the rear of the deck to the crank handle. The bell crank is carried by and shifts vertically with a connecting member supported by the front of the deck. As the front of the deck shifts vertically, the connecting member, bell crank, and rear portion of the deck also shift vertically. The bell crank is also operatively coupled with the bar for pivoting therewith, which also causes the rear portion of the deck to shift vertically.
