I've had a couple of 100s. While I've really gotten into the 82 series, I regret selling both of those 100s. Take a look at my website...it has a few pictures of the second one that I really regret getting rid of
It is worth the $150 to fix the clutch. If you were to buy some other 100, there is no guarantee that it wouldn't need the clutch rebuilt, too, and if it's never been out of the tractor, it needs rebuilding. Most gear drive CCs out there are probably in need of a clutch rebuild.
