Thanks Joe,
I just got off the phone with Richards and after talking with them I am going to do the parts install here, time consuming job but not too difficult and I'll save $300 in labor. I will have the parts on my door step Thursday.
After 41 years my PTO clutch has finally bit the dust and with another winter predicted I need my snow canon snowblower in top notch working condition. Google Gravely 816 snow canon and watch some utube videos,, it;s an awesome setup.
