The service schedule for your tractor is in your owner's manual. Additionally, Kubota publishes a "generic" service schedule on their website.
At 400 hours, if NEVER having been drained before? Oh yes, I drain and re-fill.
I think one could go on just the filters up to 400, but that's plenty far enough. Again, consult your manual.

How the oil looks is not a good way to determine if it should be changed or not. I would change it along with both the HST filter and hydraulic filter.

Looks can be deceiving. It's not motor oil so it don't get black like used oil. It will stay clear or slight amber but the properties of the oil change with heat-cool cycles and it looses it's ability to lubricate, act as hydraulic fluid and the Ph of the oil changes as well.
The first change is the most important. Go do it.

I think the GL40s came out in 2007 (or maybe 2006).
