ABSTRACT:
An apparatus for controlling the direction of a crop discharge spout on an agricultural machine with respect to an associated collector vehicle. The discharge spout has a stationary first section, a second section rotatable relative to the first section and a third section rotatable relative to the second section. The first section and the second section are rotatably connected at a lower joint; the second section and the third section are rotatably connected at an upper joint. A telescopic member extends between a drawbar on a collector vehicle and the second section. The second section of the discharge spout rotates about the lower joint in unison with the drawbar to maintain spout positioning relative to the collector vehicle. The third section moves with the second section. The telescopic member telescopically extends and retracts in response to downward and upward deflections of the drawbar. A drive motor is provided between the second section and the third section. The drive motor causes rotation of the third section about the upper joint, whereby control over the aim of the discharge spout is maintained by the operator.
