TC-24D Hitch Won't Raise

[jwstewar]

Grrr...What a frustrating summer it has been with my trusty little helper. I've had major MMM problems and lost the clutch. I think I have the MMM issues figured out, but I still need to replace the clutch. Anyway, I start mowing a section of the yard today so that my wife could do a yard sale, everything was going good. When I finished I tried to raise the mower deck so that I could get across the driveway. The MMM wouldn't come up. The 3pt isn't moving at all and the lever seems really free, almost like there is no pressure on it. Don't hear any squeals or anything and it the hitch doesn't act like it wants to move at all even though it isn't all the way down. I checked the fluid, it is nice and clear (about 125 hours since change) and it seemed full, but I added a little just in case it was low, but that didn't change anything. I checked the valve under the seat, that didn't make any diffrence. Any thoughts as to where I should start looking?

Well now I'm even more confused, I just went out to try to put the tractor away. All of sudden the MMM came up. It then starting working just fine. I drove it around the yard a couple of times and kept putting raising and lowering and it worked just fine. The adjustment lever has the normal pressure on it now. I'm lost....
