Vertical Muffler for John Deere 4050 and 4240 Diesel Tractors

Description

When your exhaust starts getting loud or you’re seeing black smoke where there shouldn’t be any, it’s usually time to look at the muffler. This vertical muffler is built specifically for John Deere 4050 and 4240 diesel tractors, giving you the proper exhaust flow and sound dampening these workhorses need to run efficiently and keep the neighbors happy.

What You’re Getting

• Oval body design that fits the original mounting points without modifications
• Proper inlet sizing with flared connection for secure, leak-free attachment
• 38-inch body length provides adequate volume for effective sound reduction
• 2-5/8-inch outlet diameter matches your existing exhaust stack
• Vertical orientation keeps exhaust directed away from the operator

Built for Real Farm Work

This muffler is designed for the bigger John Deere diesels—the 4050 through early serial numbers and the 4240—tractors that spend their days pulling heavy implements, running PTOs, and handling the demanding work that comes with row-crop and livestock operations. These are machines that need reliable exhaust systems to keep running strong season after season.

Made to Last

The oval body construction gives you more internal volume than round mufflers while still fitting in the available space under the hood. Heavy-duty materials handle the heat cycles and vibration that come with diesel operation, while the internal baffling is designed to reduce noise without creating excessive backpressure.

Good to Know

Make sure to check your tractor’s serial number—this fits 4050 tractors up to serial number 005510. The flared inlet connection means you’ll get a solid seal with the exhaust manifold, but it’s worth inspecting the manifold gasket while you’re replacing the muffler. A little anti-seize compound on the mounting bolts makes future service easier.
