Single height adjustment and control assembly for walk-behind outdoor power equipment

Outdoor power equipment comprising:

• a frame;
• a power head coupled to the frame;
• a transmission coupled to the frame and operatively coupled to the power head, wherein the transmission comprises a drive rotatable member configured to rotate about a first axis;
• a pair of rear drive wheels coupled at respective ends of a rear drive axle, wherein the rear drive axle is coupled to the drive rotatable member 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;
• and
• a wheel height adjustment mechanism including:
• a first bell crank pivotally coupled to the frame proximate to a first rear wheel of the pair of rear drive wheels, wherein a first end of the first bell crank is coupled to the rear drive axle;
• a second bell crank pivotally coupled to the frame proximate to a second rear wheel of the pair of rear drive wheels;
• a third bell crank pivotally coupled to the frame, or to a mower deck fixedly coupled to the frame, at a location proximate a first front wheel;
• a fourth bell crank pivotally coupled to the frame, or to the mower deck fixedly coupled to the frame, at a location proximate a second front wheel;
• a first linkage extending between the first bell crank and the third bell crank;
• a second linkage extending between the second bell crank and the fourth bell crank;
• and
• a first front pivoting linkage and a second front pivoting linkage pivotally coupled to the first front wheel and the second front wheel at a position vertically in-line with a pivoting location of the third bell crank and the fourth bell crank, respectively, so as to form a 4-bar linkage-type arrangement.
