Jeez, if it's not one thing it's another. These tractors are like boats. Anyway, I got some good advise on the Bulldog loader I have on my Iseki. Whats going on now is I had purchased a 5 ft finish mower in rough shape. I restored it and went to attach it to the tractor. The problem is the PTO coupler won't slip onto the PTO Shaft. The coupler is pretty weathered and I have a feeling its the corrosion and such. I greased everything up and it just barely starts. Any suggestions on cleaning it up? Or do I just buy a new one?
