I got a good one here. I made the ultimate mistake.... let a guy borrow the tractor. He uses it without a hitch. Next morning he goes to bring it back, he calls me and asks me if ive ever had hydraulic problems. Suddenly, after ive run it for 140 hours, he runs it for 1 hour and the hydraulics are super slow and wont even budge under 2000 rpm. I have already changed they trans/hydro fluid, checked the filter, you know, the basics. Its still slow and unworkable. Could the pump be failing? whayda think?
