Last week my loader on my 7275 Cub cadet was not operating like it should. You could hear the pump whining sometimes and the loader would operate really slow. Other times it would work just fine. The oil and filter have only about 50 hours on them. I noticed that the lever on the loader valve was hitting on all four sides of the mounting bracket when in use and thought that me be the problem. I thought there was not enough throw for the loader to work right. The lever holes were worn and the retaining pin for the lever was really grooved out. I welded up the pin and re-machined it. The loader lever got welded up and a new cross hole drilled in it. I also took the valve apart to make sure that there was nothing floating around in there. It was clean except for the back end float area which was full of rusty water. I put this back together and it was working fine for two days. Today I was using the tractor and it is acting up again. It appears to have a restriction in the valve or some other part of the system. One of the hoses goes stiff when using the loader lever in any position except the float position. I also noticed that if I very slowly move the lever to lift the loader it will work just fine most of the time. Then all of a sudden it goes into that same slow mode and the pump starts whining like I'm trying to lift 2000 pounds in a 1100 pound rated loader. Any ideas as to what the problem may be. It was doing this prior to my tearing into the loader valve.
