Vertical Round Muffler for Case 930 and 940 Gas & Diesel Tractors

Description

When your Case 930 or 940 starts sounding like a freight train instead of the reliable workhorse it’s supposed to be, that’s your old muffler telling you it’s had enough. A worn or cracked muffler lets in dust and moisture while letting out fumes and exhaust—problems you don’t need when there’s work to do. This vertical round replacement muffler brings back the quiet operation and proper exhaust flow your tractor needs for comfortable, all-day operation.

What You’re Getting

• Vertical mounting design that matches your original Case configuration
• Round 5-1/2″ body built to handle the heat and pressure from both gas and diesel engines
• 2-3/4″ inlet and outlet connections for proper fit with existing exhaust pipes
• 32″ overall length designed specifically for Case 930 and 940 tractors from 1960-1969
• Durable construction that resists rust-through and maintains internal baffling integrity

Built for Real Farm Work

This muffler is engineered for Case 930 and 940 tractors—the versatile utility and row-crop machines that handled everything from cultivation to hay production during the ’60s. Whether you’re running the gas or diesel version, this muffler handles the exhaust characteristics of both engine types. These tractors were built for steady, reliable work, and they deserve exhaust components that match that reputation.

Made to Last

Farm mufflers take a beating from constant heat cycling, road dust, and the occasional bump from low-hanging branches or equipment. This one’s built with materials that resist rust-through and maintain their shape under the thermal stress of stop-and-go field work. The internal baffling stays intact season after season, so you won’t hear exhaust noise creeping back after a year of use.

Installation Notes

This muffler mounts vertically just like your original, so it clears the hood and engine components without modification. The inlet and outlet pipes are sized to match original specifications, making installation straightforward with basic hand tools. If your old muffler is really stuck, a little penetrating oil on the clamp bolts makes removal much easier. Check your exhaust pipe condition while you’ve got the old muffler off—after decades of farm work, pipes often need attention too.
