I had a b6100 with a kubota tiller and bushhog and even a finish mower it was a good tractor. I sold it and bought a b7100 with a 4 way hydraulic front blade the rear pto didn’t work so I rebuilt it which involved bearings and 2 new gears which the gears were hard to find. Bought this front end loader a few weeks ago got it mounted to my tractor and I thought that would be the hardest part to the job but the hydraulics have turned out to be the pain in the rear.
I believe mine sat for years. In Florida, that’s a no-no. I don’t think the previous owner did very much maintenance. The oil was extremely dark, the hyd fluid was white, and the motor leaked everywhere. The clutch went out on me after day two, which I replaced but clearly did something wrong. While apart, I oulled the motor and replaced several gaskets and adjusted the valves. The injectors and injection pump were badly corroded and didn’t function. I replaced most of the hydraulic hoses plus the controller (Dan helped me with that too). Now the motor runs great and the FEL as well….just need to figure out the clutch.
My justification for putting more money into it was I knew I was getting closer to stopping the bleeding. Plus, affordable Compact tractors with FEls are suddenly rare here.
Used parts are hard to find, but another forum member that lives an hour away has the back half of a B7100D gear driven. Gonna pick it up this weekend for a good price!
Good luck with your FEL!
