Abstract
A greensmower having a cutting reel and a traction member and an independent electric circuit and motor for driving each. A handle is attached to the reel for mower guidance by an operator in a walk-behind position. Separate electric controls are connected to each motor for separate speeds for each motor and thereby control the clip rate of the mowing. There are low battery power read-outs and automatic shutoffs. Provision is made for traction powering of the mower even when the reel motor is not operating because of low battery power. A lift-out battery pack is shiftably mounted on the mower for producing the desired force of the mower on the ground.
