It was a big transition to move from horse to tractor. Here are pictures of Pete Peterson plowing in Ohop Valley first with his horses, and later with a 1920’s Case tractor.
My grandfather (Louie Mettler Sr. ) used to talk about having to hook the team of horses up to the tractor at times.
During 1923 a so-called Tractor war ensued, a four-way struggle between Ford, John Deere, Case, and IHC. Ford, with a massive advantage in manufacturing capacity and distribution, had the upper hand, producing an estimated 73% of all American tractors, with Case-IHC in a far away second place at 9%, and several other companies sharing the rest of the percentages.
