I realize it takes a certain amount of "work" (energy expended at a certain rate) to move a mass a certain distance in a given time. With that said, you might look at your winch specs and battery specs and see if cutting your load current in half gives you any lift (other than lowering the wiring heat loss). I assume you are directly connecting the winch to the tractor. If you deadman your winch cable to the trailer and put a pulley between it and the winch, tieing the pulley to the tractor, your ampere draw on your winch will be twice as long in duration, but half the pull (half the load is between the tractor and deadman and half on the winch. The winch just has to run twice as long as it has to pull in twice the length of cable, but using at least half, maybe less amperage to do it. You'll loose a tad in efficiency in the pulley,
but the ampere draw being less (may be a lot less due to winch efficiency at lower current/load), takes stress off all the parts supplying power to the winch and if nothing else since heat is current squared times wiring resistance, you will be quartering your heat loss in your battery, wiring and terminals.

The Revival of a John Deere Combine - by The Red, John Fritz.

The gentleman no longer farmed because the entire area was developed with housing and light industry. I had stopped several times and knocked on the door but no one would answer. My curiosity was up and I wanted to contact the owner. I wanted to see what he planned to do with the combine.
