A zero turn vehicle is disclosed, having an operator platform located adjacent to the rear of the frame. An upright riser is disposed on the frame. The vehicle uses first and second electric drive transmissions to drive the output wheels. An electrical bus or controllers may be mounted on a panel of the upright riser or on the drive transmissions to assist in providing a compact design. A pair of drive levers is mounted on the upright riser for controlling the output of the vehicle.

Vehicle having electric drive and operator platform

A hybrid zero turn vehicle is disclosed, having an internal combustion engine supported on a frame and an operator platform located adjacent to the rear of the frame. An upright riser is disposed on the frame. The vehicle uses an electrical generating device driven by the engine and first and second electric drive transmissions to drive the output wheels. An electrical bus or controllers may be mounted on a panel of the upright riser and offset vertically above the engine to assist in providing a compact design. A pair of drive levers is mounted on the upright riser for controlling the output of the vehicle.

Hybrid vehicle

A hybrid zero turn vehicle is disclosed, having an internal combustion engine supported on a frame and an operator platform located adjacent to the rear of the frame. An upright riser is disposed on the frame. The vehicle uses an electrical generating device driven by the engine and first electric drive motors or transmissions to drive the output wheels. An electrical bus or controllers may be mounted on a panel of the upright riser and offset vertically above the engine to assist in providing a compact design. A pair of drive levers is mounted on the upright riser for controlling the output of the vehicle.

A vehicle connectable to an auxiliary power unit capable of energizing a pair of fail-safe brakes that arrest rotation of a pair of electric transaxles mounted to the vehicle. Each brake has an external connector and requires electrical power to assume a non-braked state that permits free rotation of an electric motor engaged to the brake and incorporated in each of the electric transaxles. The auxiliary power unit having first and second circuits and first and second connectors compatible with the external connectors of one of the brakes.
