Rayco RG100 Catalytic Converter Rebuild
New England Supply House rebuilds catalytic converters for stump cutters and mulchers — including the Rayco RG100. 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 machine’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 Rayco RG100
The Rayco RG100 (and RG100X) is a self-propelled stump cutter powered by a Kubota V3800DI 3.8L Tier 4 diesel (99 hp) with a diesel oxidation catalyst that we rebuild. Tier 4 units (roughly 2015 and newer) carry the catalyst; check your engine year with us if you're unsure. New England Supply House rebuilds the catalytic converter for this machine and the rest of the Rayco lineup. This is not a complete list of the machines we cover — if you don’t see yours, call 774-701-6374.
