??? Put one end of extra cable on load. Wrap around pulley. Other end on tree. Winch line goes through two plates with holes. Other end of winch on a different tree.
Did I say it wrong the first time? Halve leverage if you prefer? Can't always find cooperating trees in the right spot. Extra snatchblock cable, nylon, and chain is always welcome.
Two branches and some line can make a flip flop winch if desparate.
