It appears these tractors have V-8 engines which would give them the 4566/4586 designations. The red topped cab is a 4586 I believe. These tractors were built by Steiger for IH and had IH engines and rear ends. That is how they have inboard planetaries. The engines were rated @300 hp, if my memory is correct.
