Publication number: 20220194220Abstract: An embodiment relates to a mower having a chassis and a rear suspension assembly. The chassis supports a cutter deck. The rear suspension assembly includes a support, a drive axle, and a shock absorber. The support includes a pivot, and the pivot includes a bushing to allow pivotable motion relative to the chassis. The drive axle is supported by the support and is configured to transfer power to drive at least one wheel. The shock absorber is coupled to the support and the chassis. The at least one wheel and the drive axle are configured to vertically oscillate relative to the chassis.Type: ApplicationFiled: March 11, 2022Publication date: June 23, 2022Applicant: Briggs & Stratton, LLCInventors: Steven J.

Publication number: 20220186745Abstract: Outdoor power equipment includes a chassis, a blower housing, a discharge housing, and a deflector assembly. The blower housing is supported by the chassis. The discharge housing is coupled to the blower housing and is defined by a first discharge chute and a second discharge chute that extend in opposite directions. An impeller is received within the blower housing and is configured to rotate within the blower housing to direct air from the blower housing toward the discharge housing. The deflector assembly is supported by the chassis and includes an actuator and a deflector. The deflector is movable within the discharge housing in response to movement by the actuator to selectively direct flow from the blower housing through the first and second discharge chutes.Type: ApplicationFiled: December 14, 2021Publication date: June 16, 2022Applicant: Briggs & Stratton, LLCInventors: Michael J.

Patent number: 11273705Abstract: Front and rear independent suspension mechanisms accommodating an increased range of motion to better absorb shock originating at the wheels of a riding mower to insulate the operator and reduce stress on the mower chassis and other mechanical components. The front suspension can include a front axle with pivot pockets allowing 360 degree rotation of pivots engaged within the pockets, thereby providing a greater range of absorption of shock entering the front axle at varying angles. The rear suspension can include a vertically pivoting transmission platform, providing for controlled vertical motion in the transmission while the transmission is powered by an engine by way of a belt assembly.Type: GrantFiled: September 23, 2019Date of Patent: March 15, 2022Assignee: Briggs & Stratton, LLCInventors: Steven J.
