Carefully designed for efficiency
The innovative KRONE BiG M 420 driveline allows operators to achieve work rates of more than 15 hectares (37 acres) per hour. After all, short and direct drivelines offer the best efficiency. From the axial engine, the power flows directly to the transfer box, which in turn splits the flow and transfers it to the individual mowers. Extra strong 4-groove poly V-belts transmit the power directly to the side mowers, which suspend from massive coil springs in their center of gravity. The design gives optimum floating and the tension of the coil springs is conveniently adjusted from the cab. The pushed front mower benefits from large travel to adapt perfectly to all ground contours.

Direct drivelines: BiG M 420 uses short and direct drivelines to transfer the engine power to the mowers. The transfer gearbox is positioned right in front of the axial-mount engine and sends the engine power to the individual mowers – a driveline that eliminates any losses and sends the power where it is required.
