Head assembly for a cotton harvester

In a framed crop harvester adapted for forward movement over a field of row crops, a transverse harvesting head assembly comprising:

• a transverse main frame supported above the ground by the harvester frame and including a generally horizontal first support structure extending substantially the width of the main frame and a second support structure parallel to but offset from the first structure and coextensive therewith;
• a bracket carried by and transversely adjustable with respect to the support structure;
• a fore-and-aft extending row unit pivotally supported adjacent its aft end by the bracket for rocking vertically about a generally transverse horizontal axis, said row unit movable transversely with the bracket as the latter is adjusted;
• extensible and retractable hydraulic cylinder means connected at one end to and transversely movable with the row unit for rocking the row unit vertically;
• and cylinder support means adjustably supported on the second support and connected to the opposite end of the hydraulic cylinder for transverse movement therewith as the bracket and row unit are transversely adjusted.

In a framed crop harvester adapted for forward movement over a field of row crops, a transverse harvesting head assembly comprising:

• a transverse main frame supported above the ground by the harvester frame and including a generally horizontal support structure extending substantially the width of the main frame;
• a bracket carried by, and transversely adjustable with respect to, the support structure;
• a fore-and-aft extending row unit pivotally supported on the support structure by the bracket and rockable about a generally transverse horizontal axis, said row unit movable transversely with the bracket as the latter is adjusted;
• mounting structure slidably supported by the support structure and movable transversely with the bracket thereon;
• and extensible and retractible cylinder means connected between, and transversely movable with, the mounting structure and the row unit for rocking the latter about the axis.

In a framed crop harvester having a fore-and-aft extending chassis of predetermined width adapted for forward movement over a field of crops planted in parallel rows wherein the spacing between the rows may vary from field to field, a transverse harvesting head assembly supported on the harvester frame, comprising:

• a main transverse harvesting unit support frame having first and second ends and generally transversely coextensive with the harvester chassis;
• a plurality of individual row harvesting units for receiving a like number of rows of crop;
• means for supporting the row units on the main unit support frame and for transversely adjusting the individual units thereon between the first and second ends;
• and extension frame means selectively attachable to and removable from the second end of the main unit support frame for extending, when attached, said main frame and permitting at least one of the individual row units to be adjusted outwardly beyond the second end for receiving at least one row outwardly of the chassis, wherein said support frame and the extension frame means, when attached, define continuous support structure extending generally the width of the extended frame, and wherein the means for supporting the row units on the support frame includes a transversely adjustable bracket supported by, and movable along the width of, the continuous support structure.
