hey folks I have a right side hydro pump for a john deere hd 45 or hd 75 walk behind mower. The pump I have is brand new and has not ever been used other than to put on my hd 45 and see that I got the wrong side. I needed a left side and not a right oops. anyway the pump is an eaton 778-010 pump and it is manufactured for a simplicity zt rider however can be easily modified for the john deere. I am selling the pump for 450.00 which is 500.00 less than john deere wants for it if you are interested call me at (740) 255-6449 and I can get you a pic.
