i would like one of Weisers beaver bags someday too.

If I can I often use a sled to haul by hand. If it is a tough walk use rope. Parachute cord cut long enough to go from a front foot to a rear foot. Of course you have to adjust depending on the size of the critter. I slide a piece of heavy duty clear plastic tubing on to the rope/cord, about as long as a suit case handle. Then you can pick just as you would a suit case. It works pretty well. I am not quite as strong as when I started in the 70s so sometimes if I have much luck it is a several trip deal.

My ice fishing sled

I made up handles with 6" of1 1/4 wooden handle with a few inches of 5/64 cable with micro locks on them. put one cable on front leg and one on back leg and carry by wooden handle

Finister, I took a pc of short 2 inch webbing and tied heavy para cord loop on each end. Larkshead knot on a front foot and one on back foot. sling over shoulder and beaver rides on your hip. Really works good when ya have one on each hip. A few yrs back when beaver were high dollar we trapped all the hard to get at places and quite a few days carried 3. one on each hip and one across shoulder with a front foot in one hand and back foot in other. Had 45 beaver that yr and ran a $40 average, Beaver will never shine like that again in my lifetime. Bob

Take Two back legs in each hand and carry out 4 at a time dad used to do that when we were knee high than my brother and I would carry traps out I use a sled but in areas where I catch 4 or more I skin right on the ice I try to skin them right away to make it lighter but 500 beaver through the ice makes it tough to do that everyday of the season theres really no good way around it its hard work

Piece of rope if it's a ways. Slip knot onto a back leg and front leg and loop rope over your shoulder and carry like some guys carry their purse, lol. I have used a sled but it depends. If you're fighting through thick brush, a sled isn't going to help much. Across open fields on wet snow, a sled its a cakewalk. But I like the webbing idea. I been meaning to make some kind of shoulder saving strap.
I have also used a stout beaver cutting for a handle and wired a front and hind leg to it.

I Haven't trapped beaver in a couple years but I use a strap from and old backpack with a short piece of paracord with a loop tied on each end. Put a front foot in one loop, a back foot in the other, and sling it over your shoulder like a newspaper boy carries his papers

No tail?

Plastic sled like the Otter sled. Got the small size from Cabelas years ago and it has been terrific. Put on a good rope and you can pull it over about anything but gravel easier than carrying the load.

Sled doesn't work to good in waist deep swamp

Yes. I think a turtle may have bit it off when little.

Pick up one hind, and one front , belly towards me lift and walk...I've used sleds, deer carts and loops off of sm. Square bales loop over front leg and back throw twine over shoulder- hands free

they float great.

Wrap a kids plastic slider from the dollar store around the beaver and drag, the plastic protects the hide.

Ive told on here I don't know how many times, but I guess no one is interested or tried it. Michael, one beav ain't a problem, two or more are! But I will tell again, for you buddy! I always carry lopping shears and wire when trapping beavs. Cut two poles with your shears, I usually use willow, as there is a lot around the beaver swamps. Cut a couple shorter poles, then wire together an Indian travois. I prolly didn't spell that right, but leave a space between the handles that you can fit in, and spread the other end about twice the width so it won't tip over. Wire the two poles across, then wire the beavers feet to both poles and take off. Takes longer to type this than to do it, and much easier than trying to carry them. Good luck!

Skin em In the woods.
WE used a pack frame and we normally gutted em before hauling.

We had this problem this fall right after I had some neck vertebrae fused. Surgeon said not to lift more than 15 pounds but the beavers had to go because their dam was impacting a county road culvert. My wife hauled them out and she used an empty 50 pound dog food bag. The bags were that slick fiber-type material and the outside was slick enough to drag without much friction. Cut a couple small holes in the top of the bag to slide a small tow rope through, slid the beaver inside and she slid it across the grass as easy as pie. Lots of other feed sacks are strong and slick enough to work.

duffel bag

One of these. It's a game carrier made for carrying heavier critters. Pm me if interested I'll give you the info.
