New problem on 48 8n. There is a knocking noise it the general area by the shifter/clutch. The noise is there with the clutch pedal released either moving in gear or sitting in neutral.When the clutch pedal is depressed the noise goes away. The tractor will move forward or reverse ok but I didnt move it far. Any ideas? I will look at it more this weekend and start a teardown process going for the clutch area. looks like the hydralics will have to wait till later.Thanks Joe
