Abstract
A mower includes a main body having an electric motor configured to drive a mowing member, a pair of front wheels, and a pair of rear wheels. A supporting portion is associated with the main body and a handle is connected to the main body and rotatable between a first position and a second position. The handle comprises an operation assembly operable by a user to control the electric motor. A controller prevents the electric motor from being activated by a user operation of the operation assembly when the mower is in a first state in which the supporting portion and the pair of rear wheels are used to support the main body on a supporting surface with the handle in the first position.
