CONTOURA AND 3D SAFE SYSTEM
CONTOURA ALWAYS THE SAME WEIGHT OVER THE ENTIRE WORKING WIDTH
Kverneland Actiroll soil consolidation and positive ground following features with the ‘Contoura’ System thanks to the unique 3D pendulum suspension.
The Contoura system ensures that the Actiroll segment wings always follow the ground contours: the slotted holes at the ends of the hydraulic cylinders secure a constant contact of the wings with the soil. Moreover, the weight of the central frame is transferred to the wings by two strong springs (on Actiroll and Actiroll Classic up to 8.3m) and hydraulic cylinders on other models. Therefore, the load of the complete roller is equally applied over the whole working width, whatever the working width. Each ring gang is able to release if there are obstacles.
Homogeneous weight transfer
Two springs located on each extension equally transfer the load from the middle to the side wing segments (for Actiroll/Actiroll Classic from 4.50m to 8.30m). From the Actiroll 9.50m, the load is transferred by two hydraulic cylinders and accumulator.
