Abstract

An electric lawnmower including a frame supported for movement over the ground by wheels. A reel is supported upon the frame and cooperates with a bedknife to cut grass as the mower travels along the ground. An electric motor drives the reel and includes fastening means interconnecting its parts and attaching it upon the frame. In addition, the frame is constructed to accommodate different sizes (and capacities) of motors.

Claims

1. An electric lawnmower comprising a lawnmower frame having a side wall supported for movement over the ground, a reel supported upon said frame and adapted to cut grass as the mower moves along the ground, an electric motor supported upon said frame, transmission means supported upon said frame side wall and interconnecting said motor and said reel, said motor including a rotatable armature having a shaft with one end extending through and supported upon said side wall, said motor including a housing encasing said armature and having an open end adjacent said shaft one end and supporting said shaft at its other end, said frame side wall having means slidably fitting within open ends of different diametered housings, said frame side wall including means detachably connecting to fasteners for said different diametered housings, said shaft one end having means drivingly engaging said transmission means.

2. An electric motor mounting assembly including an electric motor of the type comprising an armature including a rotatable shaft, a housing encasing said armature and having one open end, a stationary field fixed within said housing, a motor supporting member including a structural frame adapted to fit against said housing at said open end and having at least two generally concentric, annular surface portions receivable within and supporting generally cylindrical portions of different sizes of said housing, said structural frame having at least two sets of bolt receiving openings adapted to receive mounting bolts for said different sized housings, whereby to mount a selected one of said housings and said motor in cantilever fashion on said structural member.
