If, with the bottom cover off, you don't see any problems such as the release bearing frozen wearing the adjusting bolts off, on the pressure plate, or any linkage excessively worn, the problem may be just a free travel adjustment.

To understand the adjustments you need to know how the clutch linkage works. Refer to Bob and Glens pictures. when the clutch pedal is pushed down, the external spring on the pedal, goes over center to help your leg hold the pedal down. The shaft in the pedal rotates the and is splined to a cam. The cam is not connected to the release bearing carrier. When the cam rotates, it pushes the followers on the release bearing carrier, and that pushes the fingers on the pressure plate. When you release the pedal, the pressure plate fingers push the carrier back to the cam. The cam rotates the shaft and pushes the pedal back, and trips the spring back over center and snapes the pedal up. If due to normal wear, the cam is not pushed back far enough, the spring will stay in the over center position, and hold the free play out of the linkage.

The main free travel adjustment is in threaded sleeve and bearing carrier. There is also pedal height adjustment, and finger bolt adjustment.

It would help to have a manual, and follow it in order.

You also need to pull the cover panels off around clutch pedal and see if that spring is broke or rod broke worn or bent. The stop bolt could be bent hanging too. Pull the plate on bottom side and see what it looks like up in there making sure it is getting greased and hoses or fittings aren't broke and check finger setting as shown in operators manual. If any of the bearings are bad like shown in Bob's illustration below you are going to have to split tractor especially if release bearing is bad. third party image

Did you grease ALL the fittings... #5, #13, and # 31 OR #35?

Hi,I used to farm rice with 5020s in the 80s.I had one do exactly like you describe.It was ok as long as you pulled the pedal back.One day I put a new man on it who couldn't remember to pull it back.Thats right--new clutch.Now its been a long time but I think the problem was a bearing on the shaft that is operated by the clutch pedal.
Good luck,let me know what you find.
Jesse
