[AT] 12,000 lb winches

[Henry Miller]

The 12000 lbs wince means it can do a vertical lift of 12000 lbs.  Your are pulling up a ramp so we can use trig to figure out how much load you really see (we can, but I don't feel like pulling out my pre-calc books to do so), the result will be substantially less than the full  weight of the tractor.   I have a 2000 lbs ATV winch on my trailer and it has no problem loading my JD B (which is a lot lighter than your 720, but more than 2000 lbs).  Unless you are pulling tractors out of a fence or mud you won't need 12000 lbs.

Generally the duty cycle isn't a problem.  Duty cycle is at max load, and you are never at max load for very long which means you can safely run longer.  Doing tractor tiedown once it is loaded and then pulling the line out again allows a lot of time for the winch to cool while loading.  And then you give it plenty of time to sit while driving to where you are going.

Warning, winch ratings have no margin of safety, that is the most it can lift in lab conditions.  Never stand behind something being pulled uphill by a winch unless you are strong enough to stop it when something breaks and the tractor starts rolling back.  When winching something on a trailer it is best to just ensure nothing is behind the trailer that you care about tractor rolling into.   I don't think you can stop your 720.

Different winch cables have different behaviors when the cable breaks.  Many of them will come back and whip the person sitting in the tractor seat.
