I think this is a "high utility tractor" because it has 38.5 inch rear tires and is way up in the air compared to either the 450 or 460 pictures in the tractor history books. I am having trouble identifying the precise year this tractor was made because of the confusing markings. It has a large "Farmall on the chrome side strip, with the word "McCormick" in smaller letters on the chrome above it. ON the front grill the IH logo is placed in the upper section. Many of the stamped numbers on the castings have IH designators. The Hydratouch valves located directly under the steering column are leaking badly. If I can get seals for these valves, I can use the tractor almost immediately. The engine, gear, etc. seem to be in pretty good shape. I don't know the "IT manual" shop manual that Wayne is referring to. This isn't IH is it? I have the IH shop manuals that the Case Dealership currently stocks for this tractor. These manuals neglect the hydraulic system entirely. I would appreciate any information that anyone has on how this hydraulic system operates, or particularly any manuals, shop specs; or other tech info on how to rebuild this system. Andy Harris
