Abstract
Outdoor power equipment includes a frame, a power head, a transmission, a pair of rear drive wheels, and a wheel height adjustment mechanism. The power head is coupled to the frame. The transmission is coupled to the frame and operatively coupled to the power head. The transmission includes a drive rotatable member configured to rotate about a first axis. The pair of rear drive wheels are coupled at respective ends of a rear drive axle so that the rear drive axle, and the pair of rear drive wheels coupled thereto, rotate about a second axis different than the first axis. The wheel height adjustment mechanism includes a first bell crank pivotally coupled to the frame about the first axis. A first end of the first bell crank is coupled to the rear drive axle.
