Case-o-matic 830

[GarlicFarmer]

I have a 830 western special with the case o matic transmission. There is two plungers one connecting to the foot clutch and one lever is broken off. What was is the other plunger for?

That would be the converter lock up and should be hooked to a lever on the left side of the high/low shift on the dash on comfort kings or on the left of the steering column on early models.

The red circles show where the lever should be.

When would you want to lock the converter new to this set up. Thanks In advance.

being able to lock the convertor gives you the best of both worlds, when locked tractor is just like a dry clutch tractor, and speeds up travel, hit tough spot or want to slow down a bit for a corner just shift back to COM then shift back to direct when you make the turn, with a COM transmission you have 16 speeds

I am an old man but Case is my sentimental favorite because my dad had a C Case. I had an 800 COM for several years. My all time favorite tractor is my 1170--warts and all. It purrs quietly and pulls like crazy for the almost 40 years I have had it. It is not a COM.

I have gotten some flack before for being frank about the COM. One cannot ignore that farmers voted with their pocketbooks overwhelmingly for the Farmall with TA when the COM was in production.

Since you are new to the COM, here are some suggestions.

After making sure the converter lock-up feature works, my first suggestion is to mostly ignore the COM and run the tractor as a regular 8 speed. Of course, this means pick a gear that you can run all day everywhere and not have to shift gears. Since the COM tractor always starts moving in converter drive, next throttle up and engage the lock-up lever in the same breath. Then relax and enjoy the Case engine?s torque rise in the tough spots.

Another suggestion if you are the ONLY driver. To minimize the gear grinding on cool or cold mornings, bypassed the neutral start switch. Put it into the intended gear to start driving and push in the clutch pedal ---then start the engine. That became my standard practice. I hate the sound of grinding gears!!!!!!

Once you have mastered mostly ignoring the COM, then branch out and start learning the very few good features of the COM. Its good features are pretty much limited to what I call transition periods of operation. Transition periods include such as starting heavily loaded wagons in road gear, baling hay with variable windrows, mowing brush patches where variable speed is desirable, and a few other uses.

The torque converter, not locked up, is inherently inefficient, This means much of the engine's horsepower is wasted. The torque converter finds use in many applications where transitions are the norm. Bull dozers, end loaders, city traffic stop and go to mention a few.

The Case COM got abandon in favor the more efficient power shift. Also because generally speaking, the big farm tractor does not experience a lot of transitions in its normal operation. Smaller utility tractors went to hydrostatic drives because they experience a lot of transitions in their normal operations.

Which on do you need, comfort king or eagle hitch? I have 2 salvage yards close by that will have what you need.
