7711 Won't Shift

[bigv]

I was using my 7711 when going down hill, it all of a sudden became apparent it was not producing forward motion from the engine. I stopped, put it in neutral, reached down, found out the range selector lever was not in low. I put it in low and went on, except something was not right, it was like it was not pulling properly.

I stopped, put tractor in reverse, and I backed up to release slack on a logging chain I was using to pull something, and then the tractor would grind all gears trying to get it into anything but reverse.

I then got off the tractor, and I found that the clutch slave fluid was low, or rather- non-existent. I checked for leaks, but could not find any.

I noticed that pressing the clutch lever seemed to only produce a reaction from the slave cylinder where the rod from the slave cylinder slid out maybe a quarter or half inch.

I filled it up with DOT 4, and I then removed the center section of the floor pan to access the shifter mechanism. I removed the shifter, and I slid the selectors all back into a straight row.

It was still wanting to grind gears trying to go into any gear, so I took the shifter off, engaged 1st gear in low range by sliding the selector, and I reinstalled the shifter and I started the tractor with it in gear.

What I am looking at here gentlemen ? I did UTFSE via Google.

Yesterday using the tractor, the clutch seemed fine.

I got the transmission where it would shift again with the tractor off.

But the clutch isn't working while the engine is running. Pressing the pedal down isn't producing a response from the slave cylinder. In fact, I can push part of the linkage back, and then press down the pedal and the linkage will then just barely move. But, it still will not return to position.

I tried turning the bleeder screw on the slave cylinder, but was frozen, and even after using penetrating oil, the screw won't turn.

Is there any way for me to verify if I destroyed my clutch somehow or if it is just the slave cylinder ?

Master usually. The fluid disappears in the dust boot.
