John Deere 730 Transmission Fluid Drain Plugs

I am simply wanting to know for sure which drain plugs are for which, on the underside of my John Deere 730 2 cylinder tractor. I assume the drain plug right next to the Oil filter cap is the Oil crank case drain plug, correct? The second drain plug on the underside, is essentially right above the front end of the drawbar. Is that the Transmission Drain Plug? Then, back a bit further, but more towards the flywheel side of the tractor is another drain plug. Is that the "Rear axle Housing Drain Plug"? Last question: Is the "First Reduction Gear Cover Drain "plug" a plate that has 3 bolts in it on the under side, just under the belt pulley/clutch assembly, just like on the upper side of the pulley, or should I be looking for a plug, just like any other drain plug?

Thanks, in advance! - reb

Hope this helps.
 
Is yours a diesel model ? If so when draining the engine oil don't forget to drain the engine timing cover as it has a separate drain plug sort of under the flywheel cover area. And if a pony motor drain it when you do the engine as it drains down into it.

James, your response was incredibly helpful! Thank you so much! I was slow in responding, as my family was all participating (and camping) at our county fair, but this was a joy to come back to.

Thank you!!
 

Likewise, James, to my response to Mike M, I assume this is only relevant if I have a diesel, correct?

Thanks again, guys, for all your help. I am needing to get some better documents, as my manual looks to be copies of copies, and some of the pictures are not very clear.
