Whatever. I'd still install one as a matter of safety.
It was pretty common for older tractors to not have an over flow tank. About the only time those would dump anything off the radiator, was when the engine was already overheating hard.
The little B7000 I had, didn't even had a water pump. It used a thermosyphon cooling system.
You're probably just missing the small hose that would connect to that port and dump straight to the ground, but as I said, that only dumps in an overheating condition and starts by pushing steam out.It's interesting. There's an overflow port at the filler neck and a length of tubing attached to that.
I guess I'll try running the tractor for awhile and see how much coolant it wants to purge and install an overflow tank if it seems like a good idea.
Thanks for the feedback everyone.
I'll also check for ROPS attachment points but I didn't notice any. The tractor is a 1980-81.

That older system doesn't quite work like the modern ones where it expands the coolant, sends it to the expansion tank and then gets it back once things are cold.
As far as ROPS, like K5 said, that tractor didn't have any ROPS. The ones seen on pictures are either homemade ones or aftermarket ones that were offered some time ago.
Kubotas like this were sold with an optional axle-clamped ROPS (first pic). Later, when they realized very few were being sold, they decided to offer a nifty ROPS for L345 and L355 tractors that attaches with long thru-bolts at the top 3-pt connection at the back end of the trans/differential case (second pic). To encourage owners to get one, there was a low-price program for it. Not sure if its offered any more. I would guess there are some on dismantled machines in yards? This one is an old picture from "fastline"??
