The support frame includes a horizontal rail supported in generally cantilever fashion from the lift structure on the harvester, and individual row units are suspended for independent transverse adjustment on the rail by a roller assembly connected generally over the center of gravity of each unit. An additional roller attached at the upper rear of the unit runs on a second rail rearwardly and below the first rail to stabilize the unit. Removable pins lock each unit in position along the support frame. To adjust for different row widths or to move the units laterally for inspection or maintenance, the pins are removed and the units are rolled along the frame. The structure accommodates numerous combinations of row widths, including both narrow and more conventional widely spaced rows, and row capacities up to five rows while still providing good accessibility for inspection and servicing.Other References
