You could just replace winch cable. Glad it's out.
As a kid I got Granddad's Farmall tractor stuck in our lake up to the seat

.
A neighbor tried his identical Farmall and chain on the drawbar...no luck.
But luckily we lived close to a tractor dealership. Owner drove an old (early 30s?) John Deere steel wheeled tractor down with a big chain. Big JD, can't remember model but thinking it was 2 cylinder...big flywheel.
Very low rpm (putt-putt). I hooked chain on and JD never changed pitch...drug it out like it was a toy.
Then I realized why neighbor couldn't budge it since I had left it in first gear!
