High-Performance Mower Conditioner BiG M 450
The mowers

- Direct drive through Powerbands and driveshafts
- Stepless and hydraulic cutting height control
- Front mower with optional auto sideshift relative to the current steering angle
- DuoGrip centre-of-gravity suspension on the side mowers

All BiG M 450 engine power flows directly and efficiently to the three mowers. The transfer gearbox right in front of the axially mounted engine splits the power and sends it down belts and driveshafts to the individual mowers.

Ground pressure and cutting height on all units are conveniently controlled from the cab. Operators can program two cutting heights and ground pressures to the system and select the setting from the joystick.

DuoGrip: The side mowers are suspended in ball sockets in a centre-of-gravity system, which ensures a uniform ground pressure across the full working width. The side pulling forces are absorbed by two parallel arms. The design results in a large pivot range for consistently clean cuts in sloping fields and along ditches and verges.

The front mower is available with an optional sideshift function. After a sensor detects the current steering angle, the mower moves hydraulically to the right or left and relative to the current position of the wheels. The feature eliminates the risk of striping in curves and on sloping fields.
