High-Performance Mower Conditioner BiG M 450

• 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

The innovative KRONE BiG M 450 driveline allows operators to achieve work rates of more than 17 hectares per hour. The power flows from the axially mounted engine down the powerbands and driveshafts and directly to the three mowers. And superior operator comfort comes from hydraulic cutting height control from the cab and fully hydraulic ground pressure control.

All engine power on the BiG M 450 flows directly and efficiently to the three mowers. The transfer gearbox, which is positioned right in front of the axial-mount engine, splits the power and sends it down belts and driveshafts to the individual mowers.

Changing the ground pressure and the cutting height on all mowers is very conveniently managed 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.
