Gerry: It is a dry clutch, and if it was parked for awhile, my first suspicions would be clutch disc stuck to flywheel or presure plate, or it could be the pilot bushing, but I favour the clutch disc stuck idea being the problem. Could be adjustment, but I doubt it. It has traditional clutch free travel 3/16" at release bearing, clutch adjustment is through hole in bottom of casting to left of pedal.

Several things you can try to break a stuck clutch disc loose. Tie pedal down, rotate pto until it will engage. Turn pto shaft with a 3' handle wrench. Often the best wrench is a pto shaft, U joint and yoke at 90 degrees. Another idea is tie drawbar to an anchor, (tree or heavier vehicle) again tie clutch pedal down and crank engine with hand crank and transmission in gear. Try all 4 gears if necessary. Beauty of trying these, less chance of breaking something, plus you can listen and and may hear it break loose. If when tied to the tree, you can spin rear wheels with hand crank, you will probably have to split tractor.

Just had another thought, I reread your post, and I think you eliminated this idea. You said stored in gear and now can't get it in gear, I take it at some point you must have had it out of gear, right or wrong? When tractors are stored for extended periods shift rails and pto engage sliders tend to get rusty, as they rely on splash lubrication of tractor running, however if that be the case, usually you cant move lever from the stored position whether in gear or out.
