There should be 3/4" "free-play" (movement of the clutch pedal before the throwout bearing contacts the clutch release fingers to begin releasing the clutch). If you have about that much free-play, something else is the problem. The clutch MAY be gummy and oil-soaked if the engine's rear main seal or the tranny's front input shaft seal are leaking. The linings on the clutch disc could be coming apart from age, or there could be moisture and rust or other debris in there making the clutch stick. (There is a drain hole in the bottom of the clutch housing with a cotter key loosely fitted into it, to vibrate around, and keep the hole free of dirt. If this has become gummed up, oil and or water can accumualte in the clutch housing. Take a look under there to be sure the key is there, loose in the hole, and the drain hole is "open".) Some folks have had success with using brake cleaner sprayed as well as possible on the clutch by using the (bent) "straw" on a can of "brake clean" inserted into the hole where the starter goes, spraying the backside of the flywheel. Others even drill a small hole in the clutch housing, in line with the lined plate, and "hosing it down" with brake cleaner through there. If neither of these options appeal to you, or work for you, for a proper repair the tractor will have to be split, and the clutch rebulit, repaired, or replaced, as needed. For more information, surf over to the "N" Board on this site and ask any questions you may have, and/or search the archives to see what folks with similarproblems have done.
