Hi first time posting to this forum I bought a international 350 last fall to brush hog a 30 acre field as the kioti I have doesn't have the power to do it picked it up cheap didn't know much about it I hooked the brush hog up and was playing in the yard got the pto turning threw the brush hog down and the pto slowly stops spinning over about 10 feet if you keep it high it will spin just fine, also the ta clutch lever on the left side does not operate the lever will move but nothing else will seems to need adjustment any tips on the pto stopping under load?
