Straw racks in Red River Special steel separators with 15 bar cylinders, built prior to 1925, consisted of five shakers. The first four shakers were carried and driven by the Brady shaker carriers on the inside of the separator. Those shaker carriers were carried by four wooden, hangers pivoted at the top. Two wooden hangers attached to the sides of each of the four shakers of the rack and pivoted from the top. Those hangers were on the inside of the separator and moved close to the sides of the separator. When the carriers moved ahead and back, the arms attached to the sides of the shakers and pivoted at the top, produced the up and down movement of the shakers. The last shaker was carried by four hangers on the outside of the separator and driven by two short pitmans from the shaker carriers.

Wild oats was plentiful in 1923 on the Minneapolis Territory. Wild oats straw did not dry cure and become brittle as did domestic oats, barley and wheat straw. It wound around shafts and collected where other straw caused no trouble.

The wheat crop on the Salina Block was short in 1923 and Nichols and Shepard Company inquired about my going north. I never had worked in the north and told the company I would be pleased to go. Nichols and Shepard Company instructed me to report to the Minneapolis Branch and I arrived there ahead of schedule.

I was not there long, until I learned the tough wild oats straw was causing straw rack trouble in the steel separators by collecting between the shaker arms and the sides of the separators. So much straw finally collected, it bulged the sides of the separator and created so much friction, it was necessary to stop and remove the straw. The service men seemed unable to do anything to prevent it.

Nichols & Shepard Company considered re-designing the separator in such a way, the hangers would have been on the outside of the separator to overcome that trouble but it would have been costly to build and the company decided to build a differently designed separator. Nichols & Shepard Co., before building the new machine, wrote their salesmen and inquired, which separator they premerred, a Case or a Wood Bros.
