A battery-powered electric lawn mower includes battery packs mounted on a docking stations of a bus bar by way of a gravity-biased engagement. The lawn mower also includes a priority charging control logic for giving priority of charge to battery packs that have a state of charge over a threshold. The lawn mower also includes a live to drive system which alerts the user when the lawn mower is capable of moving in response to manipulation of controls. The lawn mower also includes a variable speed control which adjusts a sensitivity of speed controls such that more precise, slower speed control of the lawn mower is achieved when mowing around trees and the like.

Power source and control system for a lawn mower

A configuration of a direct drive lawnmower spindle assembly to protect sensitive electric motor components is provided. A spindle shaft of the spindle assembly is supported by upper and lower bearings. An upper end of the spindle shaft is mounted to a rotor of the electric motor and a lower end of the spindle shaft extends through the clearance opening. The lower bearing is supported by a lower bearing carrier that is mounted to the bottom of the spindle housing. The lower bearing can be serviced by removing the lower bearing carrier. A clearance gap between the spindle shaft and the clearance opening is sufficiently small to limit spindle shaft tipping to a degree that will not damage the motor. The invention also provides a friction coupling system for coupling a blade with the rotating spindle shaft.
