J Mech, of course the stock clutch won't handle 50hp. but my point (and turbo460's) was that unless the 50 HP tractor includes pulling (cut tires) and lots of extra weight, the 50 hp will never get transmitted to the ground, and wheels will spin before the clutch 20hp limit is exceeded. I can't see any reasonable way a cub cadet tractor could get more than 20hp transmitted through the clutch since the OP has stated he is likely to use 2wd, and isn't setting it up for pulling.
Bottom line, a 6pin driver and double clutch plates will probably work fine for the OP's project. A pulling clutch with aluminum plates would not be advisable as they don't slip upon engaging. Perhaps adding a heavy duty spring would assure that the clutch would handle the torque. This would be a relatively inexpensive upgrade and still suit the intended use.
