Optimum traction on heavy, wet farmland without getting the harvester bogged down, moving smoothly across the grass to pick up windrow without damaging the turf. Forage harvesters have to cope with all sorts of requirements. Electronically controlled all-wheel drive from Rexroth brings even the most difficult situation under control. Our technology prevents rear wheel spin when driving or braking on a slope – on any terrain, in any weather. This gives a forage harvester optimum traction, even under the harshest conditions.
With anti slip control, integral speed sensors continuously monitor the wheel speeds of the Rexroth hydraulic motors. If the speed differential between the front and rear axle becomes too great, it is immediately corrected by means of a special algorithm. This prevents the wheels from spinning uncontrollably.
But the BODAS controller also has another function. It receives information via CAN bus about the selected gear and the diesel engine speed – and uses this to control pumps, motors and valves on the travel drive.
