A new integrated weigh frame connects the hopper to the weigh frame via four weigh cells. This is completely separate to the chassis. Thus, there are no weight measuring points which are influenced by the traction forces of the tractor. The result is a high frequency and precise on-line-weighing procedure. A tilt sensor additionally compensates for the inclination of the machine on slopes. This signal is also used to register any tendency of the ZG-TS to drift down on a slope and, via the steering axle, to counter-steer the machine back in track.
