Check out crigby's John Deere deck page. It shows the belt routings for most of the JD mowers. See the link below.
To remove the battery tray on a John Deere STX 38 yellow deck mower, first, ensure the mower is turned off and the key is removed. Disconnect the battery cables, starting with the negative terminal. Next, locate and remove the screws or bolts securing the battery tray to the mower frame. Once these are removed, you can lift the battery tray out of its position.
If you are talking engine oil drain plug, it may be located in two locations. On the L/H or R/H side at the bottom of the engine there will be (or should be) a small pipe with a drain plug attached to it, usually this is located by the engine oil filter. I can't remember off hand where the trans oil drain plug is, but I know if you contact your local ( or closest ) JD dealer, they will be more than happy to tell you where the drain plug is for the trans oil, with no cost to you. Hope this helps!

Just below the lower radiator hose is the drain plug. Be careful and do not use force as it is plastic. jd
