They are fitted with the Kubota cutterbar with slim design for improved cutting performance. The mowing units are suspended in the centre of gravity via a large suspension spring. This design provides an even weight distribution across the entire mowing width, as well as a constant, faster and more precise adaptation to ground contours. For greater operator comfort, ground pressure of the large suspension spring is set hydraulically from the tractor cab. On the hydraulic version the tension on the large suspension spring, which controls the ground pressure, is adjusted hydraulically, to increase or lower pressure.
