ADJUSTABLE ROW SPACING FORAGE HEAD ABSTRACT OF THE DISCLOSURE Individual row units on the harvester, each including a crop transfer trough, cutting means at the forward end of the trough, and cooperating conveyors along the trough, are inda- pendently swingable relative to one another for changing the space 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 swingable movement of the units so that the dimensions of the discharge zone into which the crops are de- livered by the units may remain constant. Individual sets of disc cutters serve as the cutting means for the row units and are driven by the same mechanism that operates the conveyors, eliminating any reciprocating structure across the front of the units which would otherwise inhibit adjustable swinging thereof. Intermeshing gears of the drive walk around one another without disengagement during adjustable swinging of the units, and a hood between the units expands and contracts during swinging to present a continuous closed surface between the units regardless of their relative angular positions.
