Does anyone have this model. I like to know with the grapple hook up to the front of the skid steer and i am on cement ( side walk or street) it does not turn, I brought it back to the dealer they have already changed the pr, relief valve but still does not turn ( spin around) we have to go back and forth to get the thing to turn. then it seams to be okay for a little while. The dealer said it should turn on a dime. Duffer
