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.

SmartCut for stripe-free cuts: With some discs turning in pairs towards each other and others turning away from each other, it was necessary to redesign the degree of blade overlap to ensure cleanest cuts. For stripeless cuts in light and young crops, we have therefore increased blade overlaps on the discs turning outwards. In addition, the blades turning to the rear are now further apart to promote smooth flows of large volumes of crop.

Each disc on the mower has its own individual impact protection. When the blade hits an obstacle, the shockload is transferred to a roll pin which breaks. As a result, the disc moves 15 mm up on its threaded drive pin and clear out of the risk zone and away from the neighbouring discs.

Swapping blades is a matter of seconds – no tools required. Just use the spanner supplied.
