Under an engine overheat condition, the cap fails to vent properly and the over-pressurized tank expels hot coolant, which can spray onto the operator and cause burn injuries. Reported field incidents at time of recall: - Three burn injuries from expelled coolant (CPSC notice; Kubota's own notice cites two confirmed plus a possible third) - ~121,063 total units recalled across all four product lines ## What to do 1. Check your machine's model and serial number against the tables above. 2. If your machine is in scope, **stop using it immediately**. 3. Contact Kubota Tractor Corporation at (888) 458-2682 (888-4KUBOTA) Monday-Friday 8 a.m. - 5 p.m. CT to receive a **free replacement coolant reservoir tank cap**. 4. In the interim, the unit can be taken to an authorized Kubota dealer for a free repair of the cap. 5. Kubota was contacting all known purchasers directly at the time of recall. ## Related bulletins - **TNB02600007** covers the BX-series compact utility tractor portion of the same CPSC 19-713 recall.

Both bulletins reference the same CPSC recall (19-713) and remedy. The ZD221, ZD323-60, ZD326S-60, ZD326P-60, ZD326HL-72, ZD326RP-60R, ZD331RP-60R, ZD1021-60, ZD1211L-72, ZD1211R-60R, ZD1211RL-72R, ZG332LP, and ZG332P-60 rows are added in this same migration. Note: ZG227-60 and ZG327P-60 are NOT attached to this bulletin. They are not part of CPSC 19-713 — they appear in a separate Kubota T/GR/ZG fuel hose clamp campaign (see TNB02600019).
