What does this warning light mean?

[Doc]

Started up the tractor today and this warning light came on.
Oil is good. Battery had been on a battery tender and turned the tractor over fine.
I've never seen this warning light before that i can recall.

I found it.

Any ideas where the combustion air filter would be found?

Isn't that your regular engine air filter?

I see that that is an orange tractor. Our big John Deere had one of those on the side in a metal can type holder and was hard to get loose we we got the warning it needed changing.. Sorta looks like an old metal oil filter can type filter . I 'm think Messick's would have a diagram of the location for your model ? I hope so .
edit: when we changed it, it looked like a paper canister about like a salt box. It was all oily so did need changing.

Here is a pic of L3010 Filters ...the one I need is the big un. Plan to call local Kubota dealer and pick one up in the morning.
Yeah, Zoomer, I think it is the regular engine filter. I've never changed it. I believe it was changed by the dealer when I had some other work done (but I'm not even positive of that right now).
