Abstract
A walk-behind battery-powered lawnmower having an assembly of a reel unit and a traction unit articularly connected together in an arrangement wherein the reel unit can conform in its vertical position to the elevation of the turf which is being mowed. Thus there is an articular connection between the two units, and the reel unit rides up and down in response to the turf undulations. An electric battery is supported on the traction unit, and there is required only an electric wire connection providing the rotation drive power from the battery to the mower reel. Separate electric controls between the battery and to a motor on the traction unit and one on the reel unit provide for operational speed control to thereby select the clip rate of grass cutting in an articular assembly.
