Engine location
Engine location (FT4 engine shown)
The rear-mounted engine keeps constant weight to offset the front attachment and leaves space in the center of machine for the varying weight of the fuel tank. This allows for better coolant airflow and reduction of cab noise.
Engine exhaust
Engine exhaust stack
The engine exhaust is located at the rear of the machine. This helps to reduce interior cab noise and vibration.
