Abstract: A handlebar coupling and adjustment unit comprises a housing, a pivot pin, a manual grip and a retaining pin. The housing receives an end portion of a handlebar. The pivot pin joins the housing to the handlebar and pivotally supports the handle relative to the handle bracket. The retaining pin is connected to the manual grip and is linearly translatable in a first direction from an extended positioned projecting beyond the housing to a withdrawn position within the housing. The manual grip is rotatable while the retaining pin is in the withdrawn position between a locked position in which the housing holds the manual grip with the retaining pin in the withdrawn position and an unlocked positioned in which the manual grip is linearly translatable in a second direction to return the retaining pin to the extended position.

Abstract: A height of cut adjustment system for use with a walk behind mower. The height of cut adjustment system includes a single drive motor that is operable in a first direction and a second direction. The single drive motor is connected to a linkage assembly that supports the four wheels of the walk behind mower relative to the mower deck. When the single drive motor is operated in a first direction, the mower height of cut increases and when the drive motor is operated in the second direction, the height of cut is decreased. The height of cut adjustment system includes a height of cut indicator system that visually indicates the relative position of the wheels relative to the mower deck. The height of cut indicator system includes one or more position indicators that can be selectively positioned to visually indicate the desired height of cut for the mower.
