Will it lift itIJ absolutely! the l2, as long as it has 3" cylinders (haven't seen one that doesn't...even plain grain machines) can lift quite a bit. 8 row corn heads leave it a tad light in the back, but it is not bad. Here in NW Kansas dad and i are considering putting a 930 on a l2, which is fine when you get around 20-30 bushel grain. one of course would have to do something about the hydro reel drive, as the JD is ran from combine, but the gleaner is ran from the header. If one did not want to spring for the bish plate, that would make it more time consuming, but with a hydraulic system for the reel, and a bish plate, it would not be hard to run a JD on a gleaner. good luck!
