The clutch on my D4 won't pull back. When the motor is running the transmission is turning,I can't put it in gear. The clutch lever is forward and it moves about 1-2 back but that is all.
Also is this a wet clutch? The manual states that the clutch holds 16 qts of oil, where does the oil go into it at?
My serial # 7U1680 it sat for 12years and it worked when it was parked. Now it runs but wont go into gear,Could the pressure plate or the throw out bearing be frozen? Any ideas on how to free this up?

By the serial number your tractor has a dry clutch. It will also have a single piece top cover over the transmission and clutch, but there is a recognized procedure to cut it so just the front section can be removed by itself. Yours might have been cut already, making it a lot easier to access the clutch from the top. There is a bottom access cover used to adjust the clutch and you might be able to see what is moving or not in the mechanism as well as spraying stuff with penetrating oil, prying with a bar etc.

Not sure what will be frozen up, but I would bet something on the clutch linkage is! It’s also possible the clutch plate is stuck to the flywheel. But maybe you can get the linkage to throw out bearing and pressure plate free with some penetrating oil etc

I think the throw out bearing has an oil cup by the base of the steering clutch levers to drip into a tray inside keeping it all lubed up, so you may want to pull the wick if it has one and apply penetrating oil straight down the tube to get it right into the bearing.

I changed the cover to a two piece, I am going to remove the front cover to check to see if the brake is frozen or the through bearing is stuck,It maybe rusted.I am going to working on it today.

Hi Team,
great as the idea of cutting a full cover into a two piece one is, I could always envisage water getting in via the cut in the days before silicon sealer--I guess you did try and seal the cut line.
If not, then moisture/water ingress will be your likely cause of rusting/seizure.
A worn vertical clutch release shaft upper bushing/shaft can let water into the clutch compartment also.
Depending where you are condensation from temperature differentials and humidity is sneaky and gets in thru any small gaps.
Cheers,
Eddie B.
