2020 Krone BiG M 450

• Powerful and fuel-efficient 449 hp LIEBHERR engine

• Large 9.95 m (32'8") work width for maximum productivity

• Heavy-duty cutterbar with SafeCut blade protection

• Hydraulic running gear for added ground clearance

• SilentSpace cab offers maximum operator comfort

With the BiG M 450, KRONE presents another upgrade of its self-propelled mower. Offering huge work width, superior manoeuvrability, optimum weight distribution and tapping into enormous power reserves, BiG M 450 is the perfect mower for large and small fields, for flat and hilly land and for the most difficult soil conditions – a machine that excels in any conceivable application in any field in the world.

When the swathing hoods on both mowers are closed the augers feed the material from the sides to the middle, windrowing it into one central swath. When cutting along field edges you can also close just one hood to present a clean job to the following harvester.

Features may include:

• Direct drive through Powerbands and driveshafts

• Stepless and hydraulic cutting height control

• 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.

• Fully welded and permanently lubricated HeavyDuty cutterbar

• SafeCut shear-pin protection for each individual disc

• Satellite driveline smooths the power flow inside the cutterbar

• SmartCut system ensures a perfect cut

• Added protection from wear

The BiG M 450 sources its super sturdy disc mowers in HeavyDuty specification from the well-proven EasyCut range. The power flow enters the mower from the rear through the gearbox and flows down a driveline of massive and quiet-running spur gears that drive the satellite gears and the discs. KRONE SmartCut implements a generous overlap of those discs that turn away from each other, which translates into a perfect cut. Meanwhile, the SafeCut system protects the blade from damage caused by hitting an object.
