A walk-behind, powered device and a working assembly height adjustment system for a walk-behind, powered device

A walk-behind, powered device (10, 100) includes an engine (20, 110), a chassis (15, 150, 200) configured to support the engine (20, 110), a mobility assembly (120) including a mobility assembly frame (126, 210), a working assembly (30, 130) operably coupled to the engine (20, 110) to perform a working function responsive at least in part to operation of the engine (20, 110), a control panel (60, 180, 300) operably coupled to the chassis (15, 150, 200) and comprising a control operator (170), and a height adjuster (160). The mobility assembly frame (126, 210) is configured to pivot relative to the chassis (15, 150, 200). The working assembly (30, 130) has a fixed orientation relative to the chassis (15, 150, 200). The height adjuster (160) is configured to control positioning of the chassis (15, 150, 200) relative to the mobility assembly frame (126, 210) based on a length of the height adjuster (160). The length of the height adjuster (160) is changeable based on positioning of the control operator (170).
