I have to replace a bucket curl cylinder on my LB400 bucket because my one old one was leaking badly and the repair shop could not get it open to repair and ruined it in the process. I can't afford a new Kubota cylinder and no good used ones around, so I am looking at a replacement aftermarket. I think I have found one that will work but not sure if my hoses will fit the ports. The new cylinder says the ports are SAE #6. What ever that means. The manual says these hoses are 3/4-16 BOTH ENDS. Any and all advice will be appreciated.
