When your turbo John Deere starts sounding like a freight train and you can't hear yourself think in the cab, it's time for a new muffler box. This turbo-specific exhaust box handles the extra heat and pressure your turbocharged engine produces , keeping things civilized while protecting that turbo system from improper back pressure. A failed muffler isn't just about noise—it can throw sparks and affect your turbo's performance too. What You're Getting Compact 26cm x 19.5cm design fits those tight turbo engine compartments perfectly Built exclusively for turbo engines—won't fit non-turbo versions of these same models Heavy-duty construction handles the higher exhaust temperatures turbo engines produce Works with curved outlet pipe 58692 or straight pipe 59996 depending on your setup Direct mounting points for bolt-on replacement without modifications Built for Real Farm Work These John Deere 40 and 50 series turbo tractors were workhorses for row crop farming, hay operations, and general farm duties . Whether you're pulling a cultivator through corn stubble with your 2650 or running a mower with your 2855, these turbo engines deliver extra power without stepping up to a bigger tractor. The turbo system works harder than naturally aspirated engines, making a quality muffler essential for long-term reliability. Made to Last Turbo engines create more exhaust heat and pressure than regular engines, which means your muffler takes a real beating. This box uses heavier steel construction and improved internal baffling to handle those demands without breaking down. The design maintains proper back pressure for your turbo while reducing noise to comfortable levels, preventing internal components from rattling loose over time. Installation Notes Remember, this is exclusively for turbo models—it won't fit non-turbo 40 and 50 series tractors . Let that engine cool completely before starting work since turbo exhaust systems run extremely hot. Check your outlet pipe condition while you're at it, and have those penetrating oil ready for stubborn exhaust clamps that love to seize up from all that heat.
