Do you have a link to the installation manual you speak of?

I think the hydro. lift looks great. Not too many people have them.

I have looked a many times here at OCC and still do not see the manual to install a hydro pump and modify the rockshaft. I checked Binder Books and missed that too? At any rate, I do have it on pdf, but want a paper manual. I'am along ways from restoring my pump, so its wise to start my research now.

Any time you like, you can post pictures of your 72 in action, or what ever! How does that cultivator work out?

I only have the PDF version of the manual as well.
I found it on the following link. there is a lot of good information there.

I haven't used the cultivator yet. still working out the kinks with the hydro unit.

I have a leak where the shaft comes out the back. That darn rubber/metal washer. I can't be to tight nor to loose.
