Built for Real Farm Work
This throttle knob fits a wide range of International Harvester tractors from the compact 384 up through the powerful 4786 4WD models. It also works on the popular Hydro series tractors that many farmers rely on for loader work and precise maneuvering around the farmyard. These machines handle everything from cultivating to hay making to heavy tillage work.
Made to Last
Farm equipment controls take constant use and abuse from weather, chemicals, and operator hands. This rubber knob is built to handle temperature extremes and won’t get slippery when wet or crack from UV exposure. The material stays flexible season after season while maintaining its grip.
Good to Know
Installation is straightforward—just slide it onto the throttle shaft and secure it in place. The rubber material grips the shaft firmly once installed. If you’re working on an older tractor, clean any grease or debris from the shaft first for the best fit and longest life.
