Abstract
A sensor used to sense a path in a cultivated field is attached to a tractor. The sensor is stabilized to prevent the sensor from bouncing. The stabilizer may take the form of a coulter. In other cases the sensor and the stabilizer may be combined in the form of a heavy, massive sensor. The preferred form of the stabilizer is a flexible drag strip behind the sensor. A roller chain forms a suitable drag strip.
