"TruckTran, BuickDav: Actually there are three(3) types of mechanical IH PTO clutches.
1) The early single bent end tri-spring with NO guide posts.
2) The later style double flat end tri-springs with the guide posts.
3) The later style double flat end tri-springs with the guide posts AND the blade brake which uses a different thrust button."
Actually I knew that but didn't want to confuse the issue as I figured his mower wouldn't have the brake..right?
I would like to see a pic of that brake style PTO, none of mine have that... I am still learning on the PTO's, haven't quite got my BS in CC PTO 101 yet..... :biggrin2.gif:
