This what I use when I need to haul a moose or deer out of a difficult spot.

HELPER WINCH

Weights about 35 lbs with a 100 feet of cable.

I made a special backpack for easy carrying to where I need it.

With the right set up will pull 3000 to 4000 lbs so no moose or deer is an issue whether on the flat or a dead lift.
Once dragged a moose from the middle of a wet mucky marsh ( 75 feet). Pulled it to shore so dressing it out was not so messy. As well was getting too dark so just winched it up a tall tree 30 feet up . Returned in the morning to complete the haul.
Best money I ever spent.
Has come in handy pulling the truck out of a mud hole and clearing large trees from the trail. No mater what vechicle I am in easy to bring along .
