Check oil level in transaxle, if you have never changed it now would be a good time, also check drive shaft from engine to transaxle to make sure no pins have sheared.

Ok I did change the oil and filter still does the same thing, I even put a can of sea foam in.

Did you bleed the air out of the system as per the instruction in the previous post ?

To bleed air out Jack back tires up off ground, pull the release lever for transaxle (like you are trying to push by hand), move control to full forward hold for 5 seconds then go full reverse for 5 seconds, do this 5 times.

Push release back to driving position then repeat the same as above.
If you can't find release just do it without

You need to have tractor on Jack stands or something that is stable so it won't fall down when you have it in full forward or reverse.

If this doesn't work it might be an internal and you will need to take transaxle and pump out and rebuild it.

Did you check the drive shaft from engine to pump ?
I worked on a Cub Cadet a few years ago that had a pin sheared at the engine side, it would turn pump at idle with just a little movement on control, but when you went half way or full forward it would start slipping and not turn pump.

my tractor don't have the button on the side. Yes I pulled the drive shaft off and the key is there. But why would it come back too life after you use it for 1/2 hr or 45min.

My only thought it might have something to do with filter, did you change it when you changed oil ?
And on the filter it needs to be heavy duty, if you put regular filter on it the transaxle won't act right, if you know origional numbers you might try Cub Cadet, and John Deere, and Napa also I've gotten several heavy duty hydrolic filters from them over the years.

Any one out there have any ideas ??

yes I changed the filer too, I am using traveler premium universal tractor trans/hydraulic oil should I try something different. My book has 2-speed models to use part number 737-0333 no buddy can tell me what tis is...thanks

I remember my Ford LGT 125 that had an Eaton 11 called for 10w30 motor oil, I just looked up eaton 11 oil and the Eaton site says use premium 10w30 or 10w40 motor oil.

I just found what 737 0333 is.

Click on that it tells you what it is.

thank you I will try putting in 10w30 oil.

ok I tried putting in the 10w30 but it did the same thing but this time it came out the filler tube when I was running the tractor. Does any one no were I can get a rebuild kit for the Eaton 11ccw thanks

Before you tear it down try a different brand of filter (Baldwin makes good hydrolic filters)
Some of what you describe sounds like a bad filter.
Don't go with low cost get a good high quality hydrolic filter.

If it doesn't fix it you can use filter after rebuild.

Hey buddy when changing the filter I've been told to leave it a tad bit loose and add oil till you see it sip out filter,then snug it up worth a try easy to do and nothing to loose.
