811 Caseomatic

[Marshal51]

Can someone explain as simple as possible how to drive and operate a Caseomatic transmission. Specifically on a 811.
Trying to get the tractor home but just dont feel comfortable driving up and over hills with a tractor I have no idea how to run. Im used to the dual range transmissions in the 30 series but never operated a COM and dont want to mess anything up first time operating it. How similar are the dual range and COM? Any information would be helpful. Thanks!

Once you learn how to drive a COM you will love it. Grew up on dual range my whole life - recently purchased a COM about a year and a half ago. Completely different than the dry clutch.

Basically - push in the clutch (At idle) you may need to wait a few seconds to put into gear (there may be a little grinding). Let out the clutch and then open up the throttle. Very similar to driving a car. Once the tractor is up to speed, idle down a little and shift into direct (especially at road speeds). Please keep in mind the tractor will not hold back going down hills unless it is in direct drive!

When working - when you get to a tough spot and start to bog down, shift the lever back to COM and let the torque converter do its' thing. When out of the tough spot, shift back into direct.

I know this is a really elementary way to explain it. Once you start using it, you will get the hang of it pretty quick. I think the first thing that is alarming when you first get a COM is letting out the clutch at idle and not moving. Just give it the throttle - you'll be fine. COM is great for backing up. Let out the clutch at idle and use the brakes to stop as you back up.

Also be sure to check the oil in the COM. The dipstick is on the left side of the tractor- below and forward of the clutch. My 830 when shut off, the level is quite a bit over the full mark. I would recommend when you get a chance, change the COM filter and oil. I used ATF when I changed mine. Some folks swear by using the Case TCH oil. I found ATF cut down on gear grinding when shifting. Especially when cold.

My biggest recommendation would be to first get an operators manual and if your going to keep the tractor, as service manual. Worth their weight in gold. I'm sure John Saeli probably has these in stock

Maybe this will help:

So if Im reading this right you:

1. Have to start out in COM

2. Only push the clutch in when you want to change gears

3. Stay in direct when operating especially driving in hills to
avoid free wheel



We bought the 800 and I havent even sat on the thing yet to
figure out the levers. Anyone have any pictures/diagrams of
the direct drive/COM lever? I think I saw that direct is up and
COM is down? Does it matter if youre in direct when
changing gears? Or do you have to be in COM only to do that?



Maybe Im overthinking all of this but I just dont want to
mess anything up.

The operator manual will be your best friend for COM operation.

When you push i the clutch it will shift from direct range to low by itself.

 

[Marshal51]

By low Im assuming you mean COM?

No worries, just wanted to make sure I understood. Any and all the help the better as I just want to get this girl home!

The tranny has a Hi & Low Range that only the driver selects. The Torque Converter has the unique lock up feature that you can choose after you get rolling. Whenever you depress the clutch pedal, it automatically returns the Converter to fluid drive. That is what rfdmn is referring to.
