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.

The mower deck includes a central deck housing, a first blade housing, a second blade housing, and an actuator coupled to the central deck housing and at least one of the first blade housing and the second blade housing. The first blade housing is pivotally coupled to a first side of the central deck housing so as to be angularly displaceable relative to the central deck housing, the second blade housing is pivotally coupled to a second side of the central deck housing so as to be angularly displaceable relative to the central deck housing. The actuator is configured to selectively raise and lower at least one of the first blade housing and the second blade housing relative to the central deck housing.

A walk behind lawn mower including a frame including a handle, an engine mounted to the frame, a transmission coupling the engine to a plurality of wheels, and a user interface coupled to the transmission and including a static link rigidly coupled to the handle, a forward link coupled to a forward lever and to the static link, a reverse link coupled to a reverse lever and to the static link, and a joining link coupled between the forward link and the reverse link. The user interface is actuatable between a forward configuration and a reverse configuration using a single hand.

Single handed walk behind mower controls

An outdoor power equipment unit includes independent suspension system having a frame, a first wheel assembly, a second wheel assembly, a first laterally-extending suspension arm pair, and a second laterally-extending suspension arm pair. The first wheel assembly includes a first wheel and a first side suspension arm. The first side suspension arm is pivotably coupled at a first end to a first side structural member and is fixedly coupled at a second opposite end to a joint of the first wheel assembly. The second wheel assembly is arranged similarly to the first wheel assembly. Both the first laterally-extending suspension arm pair and the second laterally-extending suspension arm pair are configured to independently pivot about the frame to be vertically displaceable relative to the frame.

Outdoor power equipment includes a frame, a power head, a hydrostatic transmission, a pair of rear drive wheels, a drive chain, and a wheel height adjustment mechanism. The hydrostatic transmission includes a drive gear configured to rotate about a first axis. The pair of rear drive wheels are coupled at respective ends of a rear drive axle, wherein the rear drive axle is operably coupled to a driven gear. The pair of rear drive wheels, the rear drive axle, and the driven gear are configured to rotate about a second axis. The drive chain is operably coupled to both the drive gear and the driven gear. The wheel height adjustment mechanism includes a first bell crank pivotally coupled to the frame about the first axis, with a first end of the first bell crank being coupled to the rear drive axle.

A zero turn radius lawnmower, such as a stand-on lawnmower, including a main frame having a first end portion and a second end portion, a pair of drive wheels operably coupled to the second end portion of the main frame and configured to be driven independently in both forward and reverse directions, and a front axle assembly pivotally coupled to the first end portion of the main frame about a single axis. The zero turn radius lawnmower also includes a pair of caster wheels coupled to respective ends of the front axle assembly such that the pair of caster wheels are able to move relative to the main frame, as well as a mower deck coupled to the main frame by at least one first linkage and coupled to the front axle assembly by at least one second linkage.
