Efficiency and safety
The three disc mowers on BiG M 420 are well-proven technology, which is sourced from our EasyCut mower range. The fully welded and heavy-duty cutterbar with satellite driveline provides maximum stability while the power flows through the rear gearbox and down massive and quiet-running spur gears to drive the satellite gears and the discs. The discs mount in a very forward position and guarantee clean cuts thanks to perfect overlapping. All BiG M 420 models feature the standard SafeCut protection system, which gives the best possible protection when the cutterbar hits a foreign object.

SafeCut – a KRONE exclusive: Each disc on a KRONE cutterbar is individually protected. Rather than transferring the shock load of the impact to the cutterbar, the system transfers the load to a roll pin, which breaks as a result of the impact. Then the disc moves 15 mm (0.6") up on its threaded drive pin and out of the risk zone and away from the neighboring discs.
