I own a 1973 574 international tractor and every thing works real well on it . It only has about 918 hours on it. I hear a high pitched whistle sound after it warms up and it sounds like it comes from the hydraulics in the rear. Any idea what it might be or is it really anything to worry about? thanks for the help Bruce Myers
