There definitely was a Case that used the same parts as the PT-10. My manuals and parts book (for the PT-10) is very inconvenient to check today or this week, but the parts book does show a Case number too. I don't remember what that Case number was. Things to watch out for: 1. The bearings on the bell crank. They are loaded tapered roller bearings. There should be no slop in that pivot. 2. The bearing on the pitman arm driving the bell crank. 3. The counter weight on the crank pulley. 4. The link arms on the upper roller, if they wear and flare out of plane they eat the expensive belt. 5. That belt. Price from Hesston was $98 ten years or so ago. 6. The head end of the sickle. 7. The fit of guards to the sickle sections. For years I fought plugging on the right side, until I figured out it just wasn't cutting because the end guard needed a shim to make it rub against the end section. 8. Gearbox seals and gaskets. 9. U-joints inside the tongue. Needs only a single acting lift cylinder, it floats when the cylinder is retracted. 10. U joints on the PTO shaft. I found mine made dry hay faster if I left the windrow as wide as possible, though it did make a very neat windrow when narrowed, that just took a day longer to dry. 11. Condition of the crimping rollers. The rubber one is getting on in age and replacements are hard to find. Bits of the steel one may have broken off. 12. Bearings all over and the reel drive chain. 13. Skid plates underneath. 14. Float springs. 15. tires. In ten or 12 years of use, I worked on most of those things other than fixing the rollers. You only want them to bruise the stems of alfalfa, not smash those stems. Search for a PT-10 picture maybe on epay to compare with your mower/conditioner. Gerald J.
