ABSTRACT:
The invention provides an electric motor drive for a reel mower. The drive includes an electric motor, a casing, an endless traction member and a secondary output shaft. Preferably the electric motor is a brush-less permanent magnet type electric motor. The electric motor includes a rotor, a stator, and a motor housing that carries the rotor and stator, the rotor having a rotor output shaft extending from the housing. The casing is mounted to the motor housing. The endless traction member is engaged to the rotor output shaft to be circulated by rotation of the rotor output shaft. The secondary output shaft is engaged by the endless traction member to be rotated by circulation of the endless traction member. The secondary output shaft extends from inside the casing to outside the casing to be operatively connected to the reel to rotate the reel. The secondary output shaft is mounted at about the same elevation as the axis of rotation of the reel and the rotor output shaft is mounted above the axis of rotation of the reel.
