Used Tractor & Combine Harvester Exhaust Systems

The exhaust system: a vital component for engine health

The exhaust system of an agricultural tractor not only evacuates exhaust gases but also provides the necessary back pressure for optimal engine operation and reduces noise both inside the cab and externally. Proper exhaust gas evacuation directly impacts the machine’s power output, fuel efficiency, and overall performance. In agricultural equipment, exhaust systems operate under harsh conditions: heat, vibrations, dust, debris, and long hours at full throttle.

Exhaust pipe and tractor muffler: the components of the system

• Exhaust manifolds that collect gases from the cylinder head and feed the turbo.
• Exhaust pipes and bends that channel gases to the muffler.
• Vertical exhaust pipes and mufflers, common in agricultural machinery, equipped with protective caps.
• Mounting flanges, exhaust clamps, and gaskets that ensure system sealing.
• On newer tractors, post-treatment components such as particle filters and catalysts to reduce nitrogen oxide emissions, depending on availability.
• Supports, heat shields, and other exhaust parts.

Used exhaust parts available at TMC Bejenne

All our used exhaust parts are removed from machines dismantled on our 11-hectare site in Naintré. Each reference is linked to its original machine, including brand and model, minimizing compatibility errors. Our inventory covers agricultural tractors, combine harvesters, telehandlers, and, less frequently, forage harvesters. You can filter the catalog by brand and model to quickly find the exhaust pipe or manifold suited to your equipment. Every part is identified, cleaned, and inspected before being added to stock, as with all exhaust parts in our catalog.

Tractor exhaust by brand

• New Holland, John Deere, Case IH, and Claas: the most represented brands in this category.
• Massey Ferguson tractor exhaust: mufflers, pipes, and manifolds for common Massey Ferguson tractor series.
• Renault tractor exhaust: exhaust pipes and mufflers for Renault series, including older models.
• Deutz-Fahr, Fendt, Same, and Valtra: parts depending on arrivals.
• Laverda for combines, Merlo, Manitou, and JCB for telehandlers.
• Ford, Fiat, Valmet, Kubota, and Landini: some parts depending on dismantling.

Adapted or stainless steel tractor exhaust, or original part?

An adapted tractor exhaust or custom stainless steel pipe can be a temporary fix but often requires adjustments during installation. Our approach differs: we do not manufacture custom pipes. The parts we offer are original components removed from real machines, with the materials and geometry specified by the manufacturer. A quality original exhaust fits without modification, respects connection diameters and mounting dimensions, and preserves the engine behavior intended by the manufacturer.

When should the exhaust system be replaced?

• Noticeably louder noise, whooshing, or popping sounds during acceleration.
• Visible smoke at a joint or manifold.
• Perforating corrosion on the muffler or exhaust pipes.
• Abnormal vibrations caused by broken mounting flanges or torn supports.
• Loss of power associated with abnormal back pressure.
• A thorough diagnosis of the entire line, from the manifold to the outlet, prevents unnecessary replacement of still-serviceable exhaust parts.

How to choose your used exhaust system

Start with the exact brand and model of your tractor or harvester, then note the original reference number if still legible on the removed part. Next, check the connection diameter, lengths, angles of exhaust bends, and position of mounting flanges. Also verify the type of exhaust pipe or muffler—vertical, lateral, or under-hood—and the machine’s year, as exhaust systems often evolve during production runs. Our specialized technicians confirm compatibility with you, including for specific needs.
