Oil & Fuel Oil Change - How much comes out?

[Couple of Achers]

Mine also have the split oil pan, I was wondering since the oil pump pickup only goes to the bottom of one side, does the oil in the other side ever get into circulation since there is no circulation on that side?

I questioned the service manager at my local dealer about this. He said the service manual only shows one pick up as you state. He suggested that the return oil may all come back on the other side, and since the oil is well over the top of the divided part of the pan, that just through normal stirring and mixing as the tractor is being used that the oil gets mixed up and circulated.
