ABSTRACT:
A sensing unit for a row crop harvester guidance system is simply attachable and retrofittable to commercially available headers. The header comprises first and second crop dividers, each having a pair of sidewalls. A crop receiving passageway is formed between the dividers. The sensing unit comprises a rotatably mounted crop engaging arm biased into a crop engaging position in which the arm is disposed in the passageway. For mounting the unit includes a frame member which is fixed to the divider sidewalls with either bolts or clamping plates. Forwardly converging edges of the frame member are received within a tip on the forward end of the divider. The unit may be alternately fixed to dividers having different sizes and corresponding to different row spacings.
