I have a John Deere 14SB Self propel lawn mower, this is the gray one with a Kawasaki engine. The drive is in the rear. All of the sudden it started to sputter and will no longer drive. here is what i know.
- When i engage the drive lever the belt tightens and the pulley spins, so that seems OK.
- I have removed the wheels and cleaned out the build up in there and the gears looks surprisingly good.
- With the engine not running and the drive lever not engaged i can push mower forward and hear the clutch clicking, pull it back and it is free to roll backwards.
- With the engine not running and the drive lever engaged i can push the mower forward and hear the clicking but if i pull it backward both wheels lock.
- The above two points (i have read) indicate that the clutch is fine.
- Someone suggested there is a little tension spring that might be missing, mine is not missing.
What else can i look for?
Thank you, Dan

Remove drive belt and then turn drive pulley by hand, and see if the wheel(s) turn..? if so you will know its the belt to engine problem, if not then it will in the transmission so keep working your way to the wheels, could be a damage worm gear, fork or just a missing shaft key.
