Britt, are you & I the only ones we know of with a Massey 1655 diesel conversion? If you don't have, nor intend to add rear pto, you'd be much happier with a drive shaft with universal joints. That's how I went & it works great.
As far as I know we are. I think that says alot about the reliabilty of the orginal setups. I probably wouldnt have changed mine if the Kohler didnt fight me so much.
I looked at getting a drive shaft directly from the engine to the tranny but there was no way, the section where the steering gear is is in the way. I may end up with the same setup I have now but using a one piece drive shaft just like in a true 1655. I am ging to play with what I have at the moment (2 piece DS) and see if I can get it like I want it. I have a complete rear PTO on it and I think I would like to keep it for a future tiller. Plus half the fun is figuring out how tuse what you got.
