Oil color?

Gx630, gear drive, TSF2021.

I changed all oils 50 hours ago and decided to have a look at the pump oil. It was really dark in the sight glass, so I changed it and it was a very dark charcoal color.

Is that normal after so few hours?

Maybe in the engine, but not in the pump. It’s just an oil bath. It’s not breaking down or losing viscosity. Doesn’t matter what color it is. Changing it when you change engine oil is like changing brake fluid and rear end fluid at every oil change on your truck, just isn’t necessary.
