Off-set trailed and self-propelled harvesters with large wheels tend to sway - a physical conditions. This reduces the digging output and is uncomfortable for the pickers. The active swaying stability control ComfortDrive keeps the machine in a stable position and can increase digging speed up to 30 %.
Without the stability control it is necessary to fit two wheels of different flexibility to avoid the swaying of the machine. For example, if small twin wheels are fitted this creates an unintended high soil compaction. The active levelling cylinder control of the ComfortDrive keeps the machine constantly levelled and enables a digging speed over 5 kmph without swaying. It is also possible to use larger wheels for reduced ground pressure. The output and also the working situation of the pickers improves. ComfortDrive is available as option for the 2-row bunker harvester SV 260 as well as for the 2-row self-propelled harvesters VARITRON 200 and 270.
