If you do not use it, adjustment is not critical/necessary.Just a question. I understand how the clutch is used to deliver power to mower decks and snow casters. If you don't use these attachments (plow use only) is the clutch adjustment critical/necessary?
As a side note, be aware that if your tractor does not start you may have to push the clutch lever forward as there is a safety switch on it. Mine gets bumped on occation enough to mess with the switch.
