2 things come to mind that could cause your clutch problem. #1 problem I did myself first time around was installing the pilot bearing in the end of the crankshaft - I'm a retired auto mechanic and I automatically did this and it was WRONG! The pilot bearing mounts in the FLYWHEEL. With it mounted in the crankshaft like automotive applications, the input shaft isn't long enough and has no support and moves enough to not let the clutch disc slip between the flywheel and pressure plate. The pilot bearing fits perfectly in either place so it's easy to go wrong like I did and the old bearing was destroyed so I didn't see it in the flywheel when taking it all apart.
The #2 problem could be that the pressure plate fingers are not adjusted properly and the release bearing doesn't move far enough to disengage the clutch. I had to fabricate my own "gauge" to measure the distance from the flywheel surface to the surface of the fingers given in the "service" manual. I always remove the flywheel and assemble the clutch assembly to it on a bench to do the measuring and adjusting - very difficult when mounted on the tractor. You have only the slightest bit of exposed flywheel surface to get a measurement from so a custom gauge is needed. Those adjustable bolts are what break occasionally too and leave you in the field without a clutch - happened to me a couple of times over the years.
Be sure to use LocTite on the bolts from the plate to the engine, especially the ones behind the flywheel and make sure the holes are good and clean with some Brakleen !!
