Description
If your Minneapolis Moline is making more noise than a combine in bean harvest, it’s time for a new muffler. When that old exhaust system starts rattling, blowing smoke into the cab, or just plain roaring like a freight train, you’ve got work to do but can’t think straight. This vertical round muffler is built to handle the heat and pressure from those reliable engines in your Jet Star or 4 Star, bringing back the civilized sound levels that let you actually hear what’s going on around you.
What You’re Getting
- Vertical orientation that fits your tractor’s original design without modifications
- 26-inch overall length with a sturdy 4-1/4 inch round body that provides excellent sound dampening
- Properly sized inlet and outlet pipes (1-7/8 inch inlet, 2 inch outlet) that match your exhaust system perfectly
- Durable construction that resists rust-through and thermal stress from field work
- Internal baffling designed to last season after season without collapsing
Built for Real Farm Work
This muffler is designed specifically for Minneapolis Moline’s Jet Star 3 models in both gas and diesel versions, plus the 4 Star and 4 Star Super tractors. These were versatile utility and row-crop machines that handled everything from cultivating to hay work, known for their dependable engines and straightforward design. Whether you’re running a mower, pulling a disc, or doing loader work, this muffler keeps the noise down so you can focus on the job at hand.
Made to Last
Farm mufflers take serious punishment from constant heat cycling, road dust, and the occasional brush with low branches or equipment. This one’s built with materials that resist corrosion from the inside out and maintain their structural integrity under the thermal stress of stop-and-go field operation. The vertical mounting design helps drain moisture naturally, extending service life.
Good to Know
The vertical orientation means this muffler installs just like your original – no surprises or modifications needed. Before installation, soak those old exhaust clamp bolts with penetrating oil to avoid snapped hardware. Check your exhaust pipe condition while you’ve got the old muffler off, and consider new gaskets to prevent leaks that defeat the whole purpose of a quiet new muffler.
