Abstract: A locking mechanism for locking a tilt frame of a hoist to a vehicle frame comprises a semi-annular ring connected in axial alignment to the hub of a hoist lift arm. The ring is adapted to receive a pin connected to the vehicle frame. An opening is formed in the ring and is sized to permit the pin to pass therethrough. When the lift arm is advanced to a retracted position relative to the vehicle frame the opening is positioned below the pin, such that the tilt frame may be pivoted relative to the base frame. When the lift arm is pivoted out of the retracted position to load and unload a container, the ring extends in overlapping position below the pin to prevent the tilt frame from pivoting relative to the base frame.

Abstract: Individual row units on the harvester, each including a crop transfer trough, cutting apparatus at the forward end of the trough, and cooperating conveyors along the trough, are independently swingable relative to one another for changing the distance between the troughs at their forward ends in accordance with the row spacing encountered in a particular field. The spacing at the rear ends of the troughs remains unchanged in all positions of swinging movement of the units so that the dimensions of the discharge zone into which the crops are delivered by the units may remain constant. Individual sets of disc cutters serve as the cutting apparatus for the row units and are driven by the same mechanism that operates the conveyors.
