I had another post below about an 800COM I'm looking at. After searching the archives I find the lever I thought was the Caseomatic or direct drive lever probably isn't, I think it's the torque coverter lock. This is the lever on the left below the steering wheel. Does anyone have a photo of the dash layout so I can tell what I should be looking at?

Thanks to all. I think I'm getting the idea from these posts and the archives. I put it in gear in COM, use the gas to get moving, and then I can apply the direct drive? I saw refrences to a lever on the right acuating the COM in the archives and this had me confused. This is an old rusted $800.00 tractor with one bad rear rim. I need something to move round bales, (my 800 Ford is a joke in that regard after rebuilding the entire hydraulic system, the previous owner ran filthy oil for years and wore out internal clearances so it leaks no matter what), and for some tillage work. No more than 25-30 hours a year. Seems like it might work for me. I know gas isn't as efficient as diesel, but the purchase price on diesels around here is out of my league. Any other advice on this tractor would be appreciated.

Brett, that is correct. First COM to get moving then at low rpm swictch to direct. $800 is a bargain if it runs good and direct drive works. I paid $1700 for mine with no direct drive (didn't know what it was when I bought it!). Rims can be replaced or repaired. I like my gas unit but you are correct. It is a big tractor and it takes some fuel.

The Case-O-Matic should work very well for moving bales. You may need an adjustment on your bale spear design as these tractors had an Eagle hitch. The lift arms are rigid side to side - fixed spacing. Check that the Eagle locks are usable as these are a bit rare and expensive (and you need them).

Regarding your Ford 800, did you rebuild the valve? The pump will still work if worn. Hold is a function of the valve and the cylinder condition.

Good luck.

Thanks Denny, I'm familiar with the Eagle hitch as I have one on one of my VAC's. As far as the 800 Ford go's been rebuilt from stem to stern and all parts renewed. It works ok for most stuff, but a bale or anything over 150lbs on a boom pole is too much. The 800 Case should work out and the owner is willing to take my VAI in trade. It'll need a rim and quite a bit of fixing but I may get it.

There is a lever on the left side of the steering column. It locks up the direct drive clutch. The Case-O-Matic clutch is never disengaged. You start out in Case-O-Matic. Once the tractor is moving, you push the lever ahead and the direct drive clutch should lock up and you'll be in direct drive. When this is done, there should be a noticeable jump forward as it engages. If there is not jump, the direct drive of Case-O-Matic is not working. This is the problem with my 800. Apparently there are some bushings that wear out and relieve the hydraulic pressure on the direct drive clutch and therefore the only drive is through the torque converter. Without direct drive, the tractor can be used for most things but you won't have the efficiency of direct drive with heavy loads. Anytime you press on the clutch, the lever is returned to its original position with direct drive disengaged.

Someday I'll fix mine but the size of the job makes me nervous.

Thanks- So the only lever I should be seeing is on the left side going to what looks like a hydraulic valve body down past my left foot? This tractor seems to wnt to go either with the lever one way or the other. When it starts to slow due to low rpms I can move the lever to the other position and it will jump ahead and keep going. Is this what you mean?

Jim B. makes a good clarification. Guess I can't remember which way to move the lever for direct drive. I thought I pulled it. It does simply move a valve which engages the direct drive clutch.

Just to clairfy ... Direct Drive & Converter Lock are the same thing. The lever that controls Direct Drive is the one your questioning. It hydrulicly applies a clutch inside the converter that prevents it from slipping and therefore increasing torque. The tractor should always start out in torque converer drive and then when the load is managed pull the lever toward you to lock-up into direct drive. If you operate it unlocked, under load, for a prolonged time the oil may overheat and damage the transmission.

Jim explained it well. I would add that I remember many an hour working ground on an 830 with the direct drive clutch unlocked instead of dropping a gear and locking it up. And my uncle has never had a problem with the caseomatic in the 25 years he's owned the tractor. Since I've learned how caseomatic drive works, I've often thought that maybe we were lucky to get away with that. On the other hand, maybe it's not much of an issue.

My husband recently purchased a Case-Omatic 800B series and we are trying to get a manual.

If you have any idea where we might acquire one or get a copy of someone's existing manual; I would appreciate the help.

If you to the top left of this page and click on"tractor manuals" you should locate one.
