How do you power a tow hitch mounted winch?

[John0829]

For the few times that I need to use a winch on my trailer I just use my heavy duty jumper cables. They easily reach from the truck battery (extended cab dually) to the front of the trailer. Works fine for my limited needs.

Lift it with tractor or engine hoist and drive trailer to/under it.
