The BiG M 450 is the professional machine of choice when it comes to forage harvest efficiency. Its enormous agility, perfect visibility and the intuitive user interfaces are just a few examples of what sets the BiG M apart from the crowd. This means that, if you look for this unique level of forage harvesting performance, there is no alternative to the BiG M 450.
The BiG M concept
- Optimum weight distribution for great sward protection
- Enormous manoeuvrability based on a professional design
- Optional swath mergers
- Low centre of gravity for high stability
- 40 km/h road travel
- Best visibility and quickest changeovers
- Safe road travel: under 4 m transport height and under 3 m transport width
Quick and safe
The BiG M 450 is comfortable to drive both in the field up to 25 km/h and on the road up to 40 km/h with the engine speed reduced to 1,250 rpm. courtesy of the hydro-pneumatic suspension on both axles. The running gear lowers hydraulically up to 15 cm to bring the transport height of the machine down to less than four metres.
Three into one will go
When the swathing hoods on both mowers are closed the augers feed the material from the sides, 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.
BiG but very agile
Driven by wheel motors and turning through a 50° angle, BiG M is extremely easy to manoeuvre and as such also offers great efficiency in small fields. An excellent front-rear weight distribution (64% : 36%) ensures that the self-propelled mower also copes perfectly in difficult terrain.
BiG M 450
At Agritechnica 2017, KRONE introduced what was then the fifth generation of a BiG M mower. The mower conditioner received a comprehensive update and now offers a working width of 9.90 m. The new 6-cylinder, inline Liebherr engine with PowerSplit control develops 449 hp and has plenty of power in reserve.
Premiere in 1996
BiG M was unveiled to the public on 20 May 1996. With the proven EasyCut cutterbars, the BiG M achieved a working width of 9.10 m at that time. The engine of the first BiG M generated 300 hp.
The mowers
- 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.
