Features

The cab

  • Large window screens offer perfect all-round visibility
  • Comfortable seating and maximum operator comfort
  • 10-inch operator terminal with color-display touch screen
  • Optional LED package for maximum lighting
  • Modern armrest with joystick

 

Mounted on hydro bearings, the SilentSpace cab is particularly quiet, offers plenty of space and an ergonomically designed environment. The standard specification level comprises a high-resolution 10-inch touch screen terminal where the operator enters and monitors all machine settings, an armrest with integral joystick, as well as climate control and an electric cooling box. More comfort is available from the optional LED package or the Premium comfort seat.

The engine

  • 6-cylinder, 449 hp LIEBHERR engine, Emission Stage IV
  • Large 1,500-hour service intervals
  • Extremely fuel-efficient thanks to PowerSplit engine control
  • Automatic load limit control for maximum efficiency
  • Mounted on silent blocks and therefore quiet running
  • Large radiator with passive rotor for optimum temperature control

 

The 449 hp LIEBHERR engine features automatic engine control which tailors the output to the current load on the mowers. Consequently, BiG M 450 will use less fuel in lower- yield 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 very quietly in all situations.

The ground drive and running gear

  • Infinitely variable power transmission via wheel motors
  • Reduced 1,250 engine rpm in road travel for better fuel economy and ride comfort
  • Hydro-pneumatic axle suspension for high operator comfort
  • Hydraulic axle height control adjusts ground clearance to conditions

 

Wheel motors bring the power steplessly on the ground and make BiG M 450 fantastically easy to steer and maneuver. The axles boast hydro-pneumatic suspension for ultimate operator comfort and hydraulic height control, so that operators can flexibly adjust the ground clearance of the machine in field work and for road travel at reduced transport height.

The swath mergers


  • 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.

 

The conditioners

  • 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.

The EasyCut cutterbar 

  • Fully welded and permanently lubricated HeavyDuty cutterbar
  • SafeCut shear-pin protection for each individual disc
  • Satellite driveline smooth's 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.

The mowers

  • Direct drive through Power bands and drive shafts
  • Stepless and hydraulic cutting height control
  • Front mower with optional auto side shift relative to the current steering angle
  • DuoGrip center-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 power bands and drive shafts 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.

Service and maintenance

  • Sensor-based auto lubrication
  • 1,500-hour engine service intervals
  • Optimum accessibility through wide-opening covers
  • Plenty of storage space for tools and parts
  • Large 780-litre diesel and 80-litre urea tanks

 

BiG M 450 is specified with many details which make service and maintenance a lot easier and reduce the time spent on these jobs. The sensor-controlled automatic lubrication system supplies oil to most greasing points.
