Abstract
An agricultural baler is provided having an adjusting arrangement between a tow bar and a frame, that maintains the spatial relationships existing in the baler constant so that there is no effect upon the flow of the crop. The use of a sensor and a positioning arrangement provides the assurance that the repositioning is not dependent upon the capability of an operator, and finally the arrangement of the sensor in the region of the take-up device sees to it that the signals are transmitted at the exact time, not too soon and not too late.
Claims11
An improved agricultural baler having a frame, a tow bar, and a take-up device, wherein the tow bar is pivotally attached to the frame, the improvement comprising:
- an adjusting arrangement having a motor for the motorized adjustment of the tow bar relative to the frame;
- at least one sensor for determining changes in the height of ground in an area of the take-up device the at least one sensor being located between the frame and the take-up device;
- and,
- a signal processing unit for supplying data to the adjusting arrangement to effect motorized adjustment of the tow bar relative to the frame as a function of an output signal from the sensor, the signal processing unit selecting from among signals delivered by the at least one sensor, a particular signal that represents the least distance to the ground.
