I recently got a free mf 12 hydro, but, I cannot move it because it doesn't run, and I do not know where the mechanism to disconnect the hydro is... I tried putting it in neutral, but that failed.

I tried looking in the massey ferguson 12 parts book, nothing...

Does anyone know where it is?

Thanks!

It is up under the footrest and seat pan area from the right side sitting on the tractor.  It is a shaft that comes out of the hydro pump with a roll pin in it.  The roll pin should be aligned vertically for both driving and free wheeling.  The roll pin is offset to one side a little bit.  The side that sticks out more needs to be down for free wheel and up for driving.  I "think" that is right, I got rid of my 12H this spring and now cannot remember which is which.  Correct me if I am wrong guys.

Don't think it can be towed. But I have never had a hydro, in that model. Stickers on dash says, do not tow. But again, not sure if that means hydro and geared models. If it has a 2 speed differential, and you can put it in neutral, it might move then.
I am sure the guys will be in soon to answer your question.

Good score,if you lay on your back looking up at the front left side of tranny,you should notice a T handle.just turn it till you can roll the tractor. Can't remember which direction or how many turns off hand now. Good luck

No two speed but as mentioned I can't remember either on the direction of the pin. Keep turning it a quarter turn then push it slowly. You will know when it's in the right position...it frees up quickly.

I figured it out, I had it disengaged, younger brother didn't have the weight to put power to the ground... had to get 3 people to push it.

Moved it though!

If everything is working properly with your freewheel valve, these machines will freewheel fairly easily (as long as the tires are up). It shouldn't require 3 people to move it.

Tires are kinda flattish... I would have moved it by myself, had they not volunteered their help.
