I'm glad you wrote that! I wrote out a similar response, going so far as to check up on the weight of a 730 (~7000 lbs, by the way) and then got to thinking that I'd be poking my nose in something I know little about, so I deleted it.
I don't see why it couldn't tow the tractor, given a reasonable trailer rig. It has the torque and the brakes; I would think that a proper trailer could get that tongue weight to acceptable levels.
