Woodsman 790 Catalytic Converter Rebuild
New England Supply House rebuilds catalytic converters for wood chippers — including the Woodsman 790. Instead of buying a brand-new OEM converter and waiting on a dealer, send us your existing catalytic converter core and we’ll rebuild it with new internals, typically for a fraction of OEM cost.
How the rebuild works
Core exchange is required — we rebuild your catalytic converter, so we need your core to complete the job.
- Get a quote. Send us your chipper’s make and model and we’ll reply with a price.
- Ship us your catalytic converter core (with tracking and insurance).
- We rebuild it with new internals, built to meet EPA emissions standards.
- We ship it back — usually within 3–5 business days of receiving your core.
Fits the Woodsman 790
The Woodsman 790 is Woodsman's largest hand-fed drum chipper, a 21-inch-class machine. Tier 4 Final builds run a diesel rated around 275 hp (375 hp option) with a diesel oxidation catalyst (DOC) that we rebuild. Catalyst equipment came in with the Tier 4 transition — roughly 2013 and newer; older Tier 3 units may not have one, so confirm your engine year or serial with us before shipping your core. New England Supply House rebuilds the catalytic converter for this machine and the rest of the Woodsman lineup. This is not a complete list of the machines we cover — if you don’t see yours, call 774-701-6374.
