They are on facebook marketplace. You will have to do a little searching. Since the tachometer for the 611 spins backwards you will need to buy a massey-ferguson tach. that spins the same direction. This is what I have done.

There is a guy in NJ that restores them. Looks brand new when it done.

I noticed when you shift in casomatic mode and throttled down, it doesn’t grind.

@@markconley9279 Mark thanks for the reply I tried everything I could think of had the valve off and it would still grind, maybe I missed something.

Cold fluid, grind. Wrong fluid, grind. Old and warped clutch pack, grind. Idle too high, grind. Some people could run those smooth as silk. I think it depended on whether the first owner of the tractor back in the Sixties roasted the tranny or not.

@@glenirwin1110 Good day from Ontario Don't know much about case-o-matic Is that why iit was grinding at beginning. Thanks

That is the Dual-Range transmission shift lever.

@@benjaminfitz5626 ok I wasn't sure I have only been around 800 Case o matic thanks

A better way to phrase it is torque converter versus direct drive. The Case-o-matic system starts out in torque converter drive (this is the same concept as the torque converter in a automatic car). There is a lever on the dash opposite the throttle lever that when flipped engages a clutch in the transmission and locks up the transmission so that it performs like a gear drive tractor. Meaning there is no slippage like the torque converter. Anytime you step on the "clutch" pedal and let it back out or flip the lever back it will default back to the torque converter. The COM tractors spent most of their lives in torque converter mode because it defaults back to it. Hopefully that helps. They are easy systems to run and STELLAR loader/barnyard chore tractors.

Also, my 600 was only ever in torque converter in the video as best I can tell. I was not building up enough hydraulic pressure on that worn tractor to get the clutch to lock up into direct drive.
