I am SOOOO tempted to say "the only way is to fly _ME_ out there, and I will drain it for you", but that would not be the truth.

There should be a drain plug in the frame on the same side as hydraulic fill cap. It may either be underneath or on the engine side very near the bottom.
If you can get the plug loose, and pans to catch all the oil, then you don't really need to get it in the air, if you run it all the way up, all the oil will be in the lift cylinders, and not the reservoir, so you won't be draining it if you do it that way. the mast should be all the way down to get the most oil changed as possible.
