2023 Krone BiG M 450 CV

Features may include:

• Powerful and fuel efficient 449 hp Liebherr engine

• Large 9.90 m work width for maximum productivity

• Conditioners with steel tines or rollers (rubber or steel)

• Heavy-duty cutterbar with SafeCut blade protection

• Hydraulic running gear adjusts for more ground clearance

• KRONE GPS Guidance and SectionControl for maximum efficiency and 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.

• 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.

• 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.

• High-performance conditioners for haulm crops

• Full-width conditioning

• V-type steel tines for intensive and gentle treatment

• Conditioning intensity is altered without tools

The KRONE CV conditioner ensures fast and uniform wilts at high throughputs. The conditioning intensity is set by selecting a rotor speed (700 rpm or 1,000 rpm) and by tool-free adjustment of the gap between the rotor and the baffle plate.

• Augers with fingertip-controlled hoods

• Augers ensure a clean and gentle crop feed

• Crops hardly touch the ground – minimum contamination

• Perfect swath presentation for the following harvesters

Cutting, conditioning and producing one single swath – BiG M 450 completes three tasks in one operation. With the augers forming an integral part of the side mowers, they deposit the material on the swath that was formed by the front mower without the material touching the ground at all, staying very clean and reducing a pass in the harvest chain.

• Infinitely variable power transmission via wheel motors

• Reduced 1250 engine rpm in road travel for better fuel economy and ride comfort

• Hydro-pneumatic axle suspension for high operator comfort
