The color blind plow

This is a promotional film was produced by the Oliver Tractor Company in 1960's. It was made to promote the Oliver plows ,and the fact that they were compatible with any brand of tractor. This contains vintage footage of the tractors and plows at work in the field as well tons of technical information about the plows. This film also has some footage of the factory where the plows were made. I found this on an old VHS tape of my fathers, and felt it was worth posting to the web. I make no copy-write claims, and to my knowledge this should be public domain. He informed me that these tapes were available at one time from the Floyd Co museum in Charles City IA
