Bad Boy Rebel / Revolt / Rogue fire hazard from Kawasaki engine voltage regulator (CPSC 24-256)

## Affected machines This bulletin covers the **Bad Boy Mowers** portion of CPSC recall 24-256. Ten SKUs across three Bad Boy series are affected. The recall is **engine-specific**, not mower-specific. Bad Boy units in scope are those with a Kawasaki engine (model year 2021-2023) bearing the defective 21066-0785 voltage regulator. The engine model and serial numbers are on the engine fan housing. ### Affected Bad Boy models | Series | Model SKU | Deck | Engine | |---|---|---|---| | Rebel | BRB54FX850 | 54" | Kawasaki FX850 | | Rebel | BRB6135KA | 61" | 35hp Kawasaki | | Rebel | BRB61FX850 | 61" | Kawasaki FX850 | | Rebel | BRB7235KA | 72" | 35hp Kawasaki | | Revolt | BRV54FX850 | 54" | Kawasaki FX850 | | Revolt | BRV61FX850 | 61" | Kawasaki FX850 | | Rogue | BRG5435KA | 54" | 35hp Kawasaki | | Rogue | BRG6135KA | 61" | 35hp Kawasaki | | Rogue | BRG61RD35KA | 61" | 35hp Kawasaki | | Rogue | BRG72RD35KA | 72" | 35hp Kawasaki | ### Recalled Kawasaki engine models (MY 2021-2023) FJ400D, FS600V, FS651V, FX691V, FX730V, FX801V, FX850V, FXT00V. The full list of specification numbers is published on the Kawasaki product-recall page (linked below). ## Issue The **21066-0785 voltage regulator** in the recalled Kawasaki engines can fail thermally. When the voltage regulator fails, the engine overheats and can ignite. Critically, **the failure can occur while the equipment is in storage** — not just during operation. Owners cannot rely on simply parking the mower as a workaround. A widely-shared mitigation among owners while waiting for the dealer repair is to **disconnect the negative battery terminal** when the mower is not in use, since the voltage regulator's failure mode involves continued current flow. Reported field incidents at time of recall (US): - 8 reports of fires - 0 injuries ## What to do 1. Find your engine model and serial number on the engine fan housing. 2. Check your engine model against the list above; if it's one of the eight covered models, also confirm the specification number against Kawasaki's published list at https://kawasakienginesusa.com/support-resources/product-recall. 3. If your mower is in scope, **stop using it immediately** and store it away from combustible materials. Consider disconnecting the battery's negative terminal as an additional precaution while waiting for the dealer repair. 4. Check Bad Boy's recall verification page at https://badboycountry.com/kawasaki-recall to confirm whether your specific machine is affected. 5.
