Worldlawn Zero Turn (Diamondback 48) Oil Valve???

[Worldlawn User]

I have to change the oil at 10 hours, I have read every manual and searched online for the answer, but can not locate the drain oil valve. I don’t even know what to look for? There are no photos online. Help??

Look at the engine itself. Forget the manuals. Look at the base of the engine for a drain plug with a flashlight.

You should have gotten a separate operators manual for the engine.
The World Lawn website says that particular mower comes with a Kawasaki FR691V. All engine manufacturers have similar setups.
