Not 100% sure, but I'd guess 6mm.
Kubota seems to be all over the place with Zerk size. We have a M59 TLB and it has different sizes and threads on the Tractor, Loader, and Backhoe. I've only had to replace a few in 15 years, but each time turned into a project.

I finally broke down and went to Zoro.com where they have what just might be the world's best zerk thread gauge.... certainly the most expensive at $26.00. So I said, " what the heck" & got one for my mechanical buddy too....

Can't say for sure as it seems that Kubota uses several different sizes. I fixed that problem by getting the Harbor Fright variety packs (storehouse boxes). They are like $7 for 50 fittings of different sizes. Got them in metric and sae.

That’s odd. Every mower at work that has needed a new one is 6mm. Maybe the bigger stuff takes a larger fitting?
