Century 3045 won't move forward or reverse

[wildoakman]

I was moving a small load of dirt and debris when the tractor quit moving I was able to back up very slowly and turn it around then it quit again and won't move at all The clutch pedal seemed softer. I tried adjusting the clutch could it be anything other than the clutch

This may sound weird, but check the welds on the wheels to see if they broke.

While you are at it, make sure the tires aren't slipping on the rims. That has happened before also.
A simple crayon mark on the tire and wheels is all thats necessary to find out.
