Kubota Block Heater Part Number

[Don_Curley]

I am finally getting around to getting a block heater for my B2910. In searching for the best prices on the Internet, I came across the lowest priced retailer who lists the part as 70000-73274 [ZB]. Does anyone know what the suffix "[ZB]" refers to? Most everyone else just designates this Kubota part as 70000-73274 (without the ZB). Just curious ...

After a couple of tries, I never got a response from the lower-priced vendor, so I wasn't able to find out what the "ZB" stood for. Anyway, I just placed my order elsewhere for a genuine Kubota block heater so at least I know what I will be getting at this point.
