Up until 1966 we were pulling a John Deere #36 hillside combine with a Cat diesel 50. We had to use something that heavy to hold the combine when going downhill. We were dry farming 2,200 acres back then. In 1966 we purchased a Harris self propelled hillside machine new for $16,000. Talk about instant modernization! I still have the original owner/operators manual for that John Deere. Everytime I see it the memories come flooding back. The header was a flat canvas belt style with a wooden reel. Took 30' wide cuts. Most fields were 320 acres, 1/2 mile wide and a mile long. We were lucky to get 4 rounds the first day. That is one of the same fields in the picture I posted with the horses pulling that combine.
