FRAME FOR AGRICULTURAL HARVESTER CLEANER

摘要

An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly includes right and left frames interconnected by a cross member. The cross member has end castings securable to the right and left frame members. An elongated U-shaped sheet metal member extends between the castings. An elongated slot at each of the U-shaped sheet metal member terminates in a circular hole. The slot and circular hole accommodate variations in forming tolerances for the U-shaped sheet member and dissipate stresses.
