Vertical Round Body Muffler for John Deere A, AR, AN, ANH & 60-720 Series Vintage Tractors

Description

If your vintage John Deere is getting louder every time you fire it up, that’s usually your muffler telling you it’s done its job for as long as it can. When those classic A’s, AR’s, and early numbered series tractors start sounding like they’re announcing your arrival from three farms over, it’s time for a replacement. This vertical muffler brings back the civilized sound levels these workhorses had when they rolled off the line decades ago.

What You’re Getting

• Vertical round body design matches original factory configuration
• Four-bolt mounting plate with exact spacing for secure attachment
• Heavy-duty construction handles the heat and vibration of steady field work
• Direct replacement fit—no modifications or adapters needed
• Proper internal baffling for effective sound reduction

Built for Real Farm Work

This muffler fits the legendary John Deere A, AR, AN, and ANH tractors from serial number 410000 and up, plus the 60, 620, 70, and 720 series. These were the tractors that transformed American farming in the ’40s and ’50s, powering through corn cultivation, hay making, and general farm work with their reliable two-cylinder engines. Whether you’re running a fully restored show tractor or a daily-use workhorse, this muffler handles both parade duty and heavy field work.

Made to Last

Vintage tractor exhaust systems face unique challenges—decades of temperature cycles, moisture, and the occasional backfire that comes with hand-cranked starting. This muffler is built with materials that resist rust-through and maintain proper exhaust flow characteristics. The internal construction is designed specifically for the exhaust pulses of those classic two-cylinder engines.

Installation Notes

The four-bolt mounting plate bolts directly to your exhaust manifold using the original mounting pattern. Check your exhaust pipe condition while you’re at it—after 70-plus years, clamps and pipes often need attention too. A little anti-seize on the mounting bolts makes future service easier, and proper torque prevents exhaust leaks that reduce the muffler’s effectiveness.
