I have a 1012 with push-off. Couldn't get along without it in my application: load and unload quickly, load to barn later. However, I'll bet the frame has the cutouts and holes for the device. Its something you could add with some flat plate and the steel channel from 2 road signs and some steel cable. If you have an extra 1 way cylinder outlet on your tractor and some garage door springs, you have all the stuff that it takes to make your own deal. Another option would be to feed a chain or wire loop tied to a fence post and drive away from the load.
But, Its not really possible to drive off with the table fully raised and leave a full stack and an empty trailer.
