Ford 9N Tractor W/Loader

I have a running 9N tractor for sale. Its an older unit but she still runs. The tractor starts and runs good. It has been converted to 12 volt. She smokes a little at first but clears up. Does have a few leaks here and there. The loader does lift. However I'm not sure why but it only lifts about 150 pounds. Im not sure if its a pump issue, or leaky rams, or a line is blocked. It is a trip bucket. The rear arms do seem to lift and lower. Pto does work. Not going to win any beauty contest, but it is a starting point. Starts, runs and drives. Please feel free to give me a call with any questions. 970-596-331 O Ben
