Abstract
Abstract Adjustment mechanism for a baler packer in which a pair of feedfork assemblies are operated in timed relation to each other for delivery and conveying of crop material into a baler chamber. One of the fork assemblies in the feeder mechanism is adjustable in vertical and longitudinal directions in a plurality of predetermined locations. The adjustment means comprise a plurality of selectively alignable apertures of differing configurations and a connecting pin is provided for insertion through selected ones of aligned apertures at predetermined adjusted positions to thereby prevent inadvertent incorrect repositioning of the fork assembly relative to the drive mechanism and the baling chamber to prevent interference of the fork assembly with the walls of the baling chamber.
