When the over-pressurized container fails to vent properly, hot coolant sprays out of the overflow and onto the operator station, causing burn injuries. Reported field incidents at time of recall: - 6 reports of burns to operators from hot coolant - 0 fatalities reported ## What to do 1.

Each row is named with the SKU first followed by the consumer-facing branding (Z580, Z580-D, Z595-D) so owners can find their machine either way. The Z580 and Z580-D are gasoline and diesel variants of the same chassis; the Z595-D is a higher-output diesel. These are predecessors to the current Toro Z Master 2000/4000/6000/7500-D line already in the library and represent a different generation of liquid-cooled commercial Z Master mowers.
