Hi i own a 1999 Farm Pro 2420 2wd front end loader tractor. I recently have had a problem with starting it. When I turn the key to start it i get a grinding/clicking noise. I charged the battery and had the starter and altenator checked and all looked good. I beleive it has something to do with the flywheel when i pulled off the starter i noticed the teeth of the fly wheel were grinded down to almost nothing. I am now stuck wondering what do i do next? Do I disasemble the whole motor and replace the flywheel or is the problem somewhere else? Thanks for any help. -Clinton
