When driving and you push the clutch in the tractor comes to a stop quickly. If you are on a slight incline with the clutch pushed in the tractor will not roll. I jacked up the tractor and unhooked the MFWD shaft. It is hard to turn both rear tires, the right side is slightly worse. I pulled the screen and there was nothing alarming on it. Oil is clean. I ran the tractor when it was in the air the left side will spin and the right side will hardly turn. Could I be looking at a brake issue on both sides? A warped disc or something? I didnt really want to pull a final drive for nothing. Anyone had this issue? Thank you.
