Cub Cadet Tank M / Tank S / Tank L vent valve grommet fire hazard (CPSC 13-733)

## Affected machines About **2,100** Cub Cadet commercial zero-turn lawn mowers manufactured **January through December 2011** (full calendar year — broader window than the related CPSC 11-733 recall). A label located on the **frame under the foot rest** lists the model number and the month and year date of manufacture (DOM). ### Affected models | Model | Type | |---|---| | M54-KH | Tank M-series, Kohler engine | | M60-KH | Tank M-series, Kohler engine | | M60-KW | Tank M-series, Kawasaki engine | | M72-KW | Tank M-series, Kawasaki engine | | S6031-KW | Tank S-series, Kawasaki engine | | S7237-KW | Tank S-series, Kawasaki engine | | TANK L48 | Tank L-series | | TANK L60 | Tank L-series | The KH suffix indicates Kohler-engined units; KW indicates Kawasaki-engined units. ## Issue **Fuel can leak from the vent valve grommet on top of the fuel tank during operation**, posing a fire hazard. This is distinct from the related CPSC 11-733 recall on a similar Cub Cadet population — that one involves the **rear mounting screws on the bottom of the tank**, not the vent valve grommet on top. Reported field incidents at time of recall: - 106 reports of fuel leaking or seeping from the top of the tank - 1 fire - 0 injuries The high incident count (~5% of the recalled population) indicates this defect was actively manifesting in the field rather than being a precautionary recall. ## What to do 1. Check your model and date of manufacture against the table above. The label is under the foot rest. 2. If your mower is in scope, **stop using it immediately**. 3. Contact an authorized Cub Cadet service dealer for free repair. Cub Cadet was contacting registered owners directly at recall time. 4. Call Cub Cadet at (888) 848-6038 Monday-Friday 8 a.m. - 5 p.m. ET, Saturday 9 a.m. - 5 p.m. ET, or visit https://www.cubcadet.com and click "Product Recalls" for more information. ## Hazard Severity is rated **critical** because of the fire risk from fuel leakage. The 1 fire incident at recall time confirms the hazard had manifested in the field. ## Related bulletins - **TNB02600061** — CPSC 11-733 (April 2011) Cub Cadet rear-mounting-screws fuel leak. Tank L48 and Tank L60 SKUs overlap with this bulletin (different defect, overlapping SKU population — owners of Tank L48/L60 from Jan-Mar 2011 should check both). - **TNB02600032** — CPSC 24-256 Cub Cadet ZTX-6 voltage regulator - **TNB02600033** — CPSC 2019 Cub Cadet RZT SX EFI fuel-tank-neck cracking - **TNB02600034** — CPSC 20-703 Cub Cadet Pro Z 760 LKW EFI fuel-injector leak - **TNB02600053** — CPSC 13-040 Cub Cadet Kawasaki engine fuel filter (different recall, same era; Tank M60-KW and M72-KW are also in scope for that recall via their Kawasaki engines) The 2011-2013 era was particularly active for Cub Cadet recalls — between 11-733 (April 2011), the CPSC 13-040 Kawasaki engine recall (Nov 2012, sibling bulletin TNB02600053), and 13-733 (April 2013), Cub Cadet commercial mowers from this period have multiple distinct fuel-system fire-hazard recalls. Dealers receiving an MTD-built Cub Cadet from this era in for service should check all three. ## Source - U.S. Consumer Product Safety Commission, "MTD Products Recalls Cub Cadet Commercial Lawn Mowers Due to Risk of Fire (Recall Alert)," recall 13-733, April 29, 2013. - Manufactured by MTD Products Inc, of Cleveland, Ohio. - Cub Cadet recall page: https://www.cubcadet.com/en_US/recall-commercial-lawn-mower-recall-2013.html
