What the BiG M 450 is used for
The BiG M 450 is used by specialist contractors and large forage operations that need to mow extensive grass acreage quickly for silage, haylage or hay. Its triple mower-conditioner arrangement can cut a very broad swath in one pass, helping make use of narrow weather opportunities.
Unlike a tractor-mounted combination, it is self-propelled with hydrostatic drive. It is best suited to operators who can support a complex, high-output machine and have work volumes large enough to justify it.
Why the Krone BiG M 450 stands out
The key attraction is self-propelled triple-mower output: a 9.9 to 13.7 m cutting width, approximately 449 hp diesel power and hydrostatic drive in one purpose-built machine. Tine or roller conditioning is available. Its specialist nature means service history, operating condition and suitability for the workload deserve particularly close attention.
Buying a used Krone BiG M 450
Have a used BiG M 450 inspected, concentrating on diesel engine starting, smoke, oil pressure and service evidence. Check hydrostatic drive response, hydraulics, mower beds, conditioner parts, steering, brakes, tyres and any leaks. Inspect panels, corrosion and repaired damage, and confirm serial and registration details match the machine. Confirm figures and originality against TractorData.com and club records; values vary by condition, so check current listings rather than a fixed price.
