I have a 1960 Case 830, Model 841, could someone tell me what a case o matic is, and how you determine if a tractor has one.

I just bought (the same?) - on the serial number plate - an 841c. The Case "dealer" says there is no such thing. I find very few references to it.

What manual do I use? What model is it closest to for parts? Help. Thanks.

Mr. Kampton Case o matic was wonderful if used as intended by the manufacture. It was not the same as Farmall"s Torque Amplifier or Minnie Mo"s A.T. Case O Matic was utilized starting heavy loads then shifting to direct drive, of course it could be used under very heavy conditions but the temperature of the torque convertor would have to be monitered. I can remember many county fairs when they had pulling contests when the tractors were hitched drawbar to drawbar and th Case O Matic would always ,I mean Always pull the other tractor backwards because the torque converter would cushion the amount of torque required to move the load and then walk away with it. I don"t know of a single time that a tractor equiped without Case O Matic out pulled a tractor equipped with it. You just can"t beat it, C.O.M. was just ahead of the times.

Case-O-Matic is a Torque Converter "clutch" before the 8-Speed manual transmission. The torque converter itself also has an internal hydraulic �lock-up� clutch which, when applied, prevents torque converter slippage... which is actually direct-drive just like a mechanical friction clutch when engaged.
The operator must control the system properly to take advantage of it's capability. The clutch pedal has no "feel" of engagement. It is simply a foot control of a hydraulic valve. So, it should be operated much like a car with an automatic transmission. Always depress the pedal when the engine is idling... then manually shift into any gear desired... then release the pedal and throttle the engine with either the foot or hand control. The tractor will accelerate to the selected RPM pending the draft load. If load is not excessive then engage direct-drive by pulling-up the lever on the left side of the steering wheel. If the load is too great and the RPM drops off, such as hard-ground during plowing, then release the lock-up clutch to return to torque converter drive by pushing the control lever back down. Wheel torque will increase without changing manual gears. Whenever the tractor is slowed to a stop, the lever needs to be down or the clutch pedal depressed which will also return the lever to torque converter drive. So. initial drive-away will always be in torque converter mode or sometimes called "Low Range".
Hope that helps you take advantage of a very capable system if proper controlled.

Thank you for your answer, I wasn"t sure if my tractor was equipped with this option. I just knew the clutch was a different kind of clutch.
Thank"s
