Donavon, The Big 400s were the first "modern era" tractor that Case offered. 8spd tranny, independent PTO and Hyds. They also came equiped with better seats, and Power Steering opt. The Eagle Hitch, (CatI)had already become available on earlier Case VAs, SCs, and DCs. THe low reving, big displacement Case engined had a reputation for their brute torque when the job got tough. The 800 with Case-O-Matic trans, was a revolutionary concept in farm tractors. Today torque converter drives are the norm in construction equipment. The COM trans was widly misunderstood. Many Case Dealers themselves, didn't know how to demo and sell the concept. Bigest misconseption was that the trans was slipping. Fact was that the TC was multiplying trans. input torque up to 3.14 times in a given gear.(example, engine flywheel torque 250 pound feet---TQ output to tranny 785 pounds feet available at tranny input shaft. Other words the TQ automatically adjusted to the load without the need to stop and select another gear. The TQ also had a direct lockup so when loads were light the converter became a direct link between the flywheel and tranny. with the flip of a lever. Many people complained that they were jerky when hooking to equipment, but the dealer didn't show them how smooth they could be if they inched into position by just holding the brakes. (You wouldn't back your PU with auto by giving it some throttle and pulling it in and out of revers would you?) Enough here; Our Family became Case dealers in 1931. I remember when we got in our first 400 diesel and the first 800 COM in to sell. We also had the Dairy farm, so I got lots of time to learn the "what tos and what not tos" of these tractors. They also were and still are, one of the most distinctive and identifiable tractors in feilds and shows. Join us over on the CASE forum family, with pics, and comentary Loren, the Acg.

Today's Featured Article - Tuning-Up Your Tractor: Plugs & Compression Testing - by Curtis Von Fange. The engine seems to run rough. In the exhaust you can hear an occasion 'poofing' sound like somethings not firing on all cylinders.
