With the BigM 450, Krone presents another upgrade of its self-propelled mower. Offering huge working width, superior manoeuvrability, optimum weight distribution and tapping into enormous power reserves the BigM 450 is the perfect mower for large or small fields, hilly or flat terrain.

  • Powerful and fuel-efficient 449hp LIEBHERR engine
  • Large 9.95m (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

The Ground Drive and Running Gear:
Wheel motors bring the power steplessly to the ground and make the BigM 450 fantastically easy to steer and manoeuvre. The axles boast hydro-pneumatic suspension for ultimate operator comfort and hydraulic height control allows operators to adjust the ground clearance of the machine in field work and for road travel at a reduced transport height of  under 4m.

  • Infinitely variable power transmission via wheel motors
  • Reduced 1250 engine rpm for efficient road travel
  • Hydraulic axle height control adjusts ground clearance
  • Hydro-pneumatic axle suspension for operator comfort
The Mowers:
The innovative 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. Superior operator comfort comes from hydraulic cutting height control from the cab and fully hydraulic ground pressure control.
  • Direct drive through Powerbands and driveshafts
  • Stepless and hydraulic cutting height control
  • DuoGrip centre-of-gravity suspension on side mowers
  • Front mower with optional auto sideshift relative to the current steering angle
The Swath Mergers:
Cutting , conditioning and producing one single swath – the BigM 450 completes three tasks in one operation. The swathing hoods open and close from the cab, spreading the grass across the full cutting width or feeding in to the central swath formed by the front mower. The augers form an integral part of the side mowers, they deposit material on the swath that was formed by the front mower without the material touching the ground, ensuring the crop stays clean and reducing a pass in the harvest chain.
  • Swathing hoods open and close conveniently from the cab.
  • Swath merging augers are driven by belts
  • Augers ensure clean crop feed, controlled at your fingertips
The Conditioners:
The Krone CV conditioner ensures fast and uniform wilts at high throughputs. The conditioning intensity is set by selecting a rotor speed and by tool-free adjustment of the gap between the rotor and the baffle plate.
  • Full-width conditioning
  • V-type steel tines fon a 64cm diametre rotor
  • Conditioning intensity can be altered without tools
The Cab:
Mounted on hydro bearings the SilentSpace cab offers plenty of space and an ergonomically designed environment. The standard specification level comprises of a high-resolution 10-inch touch screen terminal where the operator enters and monitors all machine settings, an armrest with integral joystick including customizable buttons, climate control and an electric cooling box.
  • Large window screens offer perfect all-round visibility
  • Comfortable seating and maximum operator comfort
  • 10-inch operator terminal with colour-display touch screen
The Engine:
The 449hp LIEBHERR engine features automatic engine control which tailors the output to the current load on the mowers. Consequently the BigM 450 will use less fuel in lower yielding crops. A new load limit control system monitors the engine speed and reduces the ground speed when engine speed is very low. Mounted on silent blocks the engine runs quietly in all situations.
  • 6-cylinder, 449hp, emission stage 4
  • 1500 hour service intervals
  • Extremely fuel efficient thanks to PowerSplit engine control
