1. A power unit support assembly for a walk-behind mower, the power unit support assembly comprising:
- a mower frame including a fastener receiver and a receiving member having an aperture; and
a plurality of power unit support members each adapted for supporting a different type of power unit, each support member including an extending member forming a bent tab with respect to said support member for sliding into, with clearance, said aperture of said receiving member so that said extending member must be rotated and slid into said aperture, said extending member extends beyond said aperture so that said extending member contacts a portion of said receiving member prohibiting a linear withdrawal of said extending member from said aperture so that said support member is rotated in order to withdraw said extending member from said receiving member aperture and said support members including a securement portion aligned with said fastener receiver to receive a fastener to secure the securement portion with the mower frame for providing a rapid disconnect between said support member and said mower frame such that the plurality of power unit support members and mower frame providing a system that enables different type of power units to be rapidly substituted for one another on said mower frame and said plurality of power unit support members each being releasably connectable to the mower frame, via said receiving member and fastener receiver, such that the system provides for the respective different types of power units to be rapidly interchangeably mounted to the mower frame providing the walk-behind mower with different types of power units for specific mowing tasks.

Abstract
A walk-behind mower includes a frame, and a cutting unit connected to the frame and at least one cutting element. Interchangeable power unit support assemblies are each adapted to support either a reciprocating engine or a battery unit. One of the power unit support assemblies is releasably connected to the frame. An electric motor is provided to displace the cutting element. An output voltage generated by either the reciprocating engine or the battery unit mounted on the power unit support assembly energizes the electric motor.

8. A power unit support assembly for a walk-behind mower, the power unit support assembly comprising:
-
a mower frame including a fastener receiver and a receiving member having an aperture; and a first support member having an energy storage device mounted thereto and a second support member having a reciprocating engine mounted thereto, each of the first and second support members structured with an extending member forming a bent tab with respect to said support member for sliding into, with clearance, said aperture of said receiving member so that said extending member must be rotated and slid into said aperture, said extending member extends beyond said aperture so that said extending member contacts a portion of said receiving member prohibiting a linear withdrawal of said extending member from said aperture so that said support member is rotated in order to withdraw said extending member from said receiving member aperture and said support members including a securement portion aligned with said fastener receiver to receive a fastener to secure the securement portion with the mower frame for providing a rapid disconnect between said support members and said mower frame such that the first and second support members and mower frame providing a system so that different type of power units are rapidly substituted for one another on said mower frame to be releasably connected to the mower frame such that the energy storage device and the reciprocating engine can be rapidly substituted for one another to interchangeably mount to the mower frame to provide the walk-behind mower with a choice of operating power to the mower. - View Dependent Claims (9)

10. A power unit support assembly for a walk-behind mower, the power unit support assembly comprising:
-
a mower frame including a fastener receiver and a receiving member having an aperture; and a plurality of power unit support members, each support member structured to be connected to a particular one of a plurality of power units, each power unit being of a different type than the other power units, and each respective support member structured with an extending member forming a bent tab with respect to said support member for sliding into, with clearance, said aperture of said receiving member so that said extending member must be rotated and slid into said aperture, said extending member extends beyond said aperture so that said extending member contacts a portion of said receiving member prohibiting a linear withdrawal of said extending member from said aperture so that said support member is rotated in order to withdraw said extending member from said receiving member aperture and said support members including a securement portion aligned with said fastener receiver for providing a rapid disconnect between said support members and said mower frame such that the plurality of power unit support members and mower frame provide a system so that different type of power units are rapidly substituted for one another on said mower frame and also to receive at least one rapid installation fastener to releasably fasten the respective support member to the mower frame such that the respective different power units can be interchangeably mounted to the mower frame and utilized to provide operating power to the mower.
