ABSTRACT:
A sensing unit for a row crop harvester guidance system is attached to a row crop harvester header. The header includes first and second crop dividers. Each divider has a pair of sidewalls. A crop receiving passageway is formed between the dividers. The unit comprises a rotatably mounted crop engaging arm biased into a crop engaging position by a torsion spring. In the crop engaging position the arm projects outwardly from one sidewall of one of the dividers into the passageway. The spring tension is adjustable to vary the amount of force required to actuate the crop engaging arm. Variation in the force is desirable to permit the sensing unit to operate reliably in a variety of crop and field conditions. Rotation of the crop engaging arm is limited by a shock absorbing guide movable in a slot in the sensing unit frame. The sensing unit has a housing for shielding critical components mounted on the unit from exposure to dirt and debris. The housing is readily removable from the confines of the divider to expose the components for servicing.
