This is our round bolt on muffler for the John Deere 320, 330, 420, 430, 435, 440, & 1010 Gas tractors. This replacement muffler is perfect for the budget conscious tractor enthusiast. The round design of this muffler matches the original look found on the late John Deere two-cylinder tractors. This muffler looks great painted black or silver as many restorers prefer those two colors for this design. The muffler stands 17-3/4 inches tall.  The replacement muffler is designed for clamping to the exhaust pipe adaptor found below. This muffler allows smooth exhaust flow, yet controls sound at reasonable levels. Replaces John Deere Parts AT10656T and AM3101T featured on John Deere two-cylinder tractors.
