When your old tractor starts acting finicky on cold mornings and won’t settle into a smooth idle after starting, the problem might be as simple as a worn-out choke knob. This little control is what lets you manually enrich the fuel mixture for cold starts and then lean it back out as the engine warms up. Without proper choke control, you’re fighting uphill battles every time the temperature drops.
What You’re Getting
- Direct replacement knob that threads right onto your carburetor choke shaft
- Positive grip design that won’t slip when your hands are greasy or cold
- Durable construction that handles the daily use these old Fords were built for
- Proper fit ensures smooth choke operation without binding or sticking
Built for Real Farm Work
This choke knob fits the Marvel Schebler carburetors found on Ford’s N-series tractors—those reliable workhorses that have been helping farmers get things done for over 80 years. Whether your tractor spends its days pulling a plow, running a brush hog, or powering a hay baler, proper choke control makes the difference between easy starts and frustrating mornings in the shop.
Made to Last
Ford N-series tractors were built to work hard and last long, and this choke knob follows that same philosophy. The knurled surface gives you positive grip even when wet, and the materials resist cracking and wear from constant exposure to engine heat and weather.
Good to Know
Installation is straightforward—remove the old knob by unscrewing counterclockwise, then thread on the new one until snug. Don’t overtighten as this can damage the carburetor shaft. While you’re working on the carburetor, it’s a good time to check the choke plate operation and clean any built-up gum or varnish from the choke shaft.
