If you have a tractor or electric winch I will agree, but out in the field you could not be further fro the truth.
I suffered a broken back during a stalking accident. this was many years ago and it has resulted in a constant battle with pain and mobility. this has resulted in myself finding the easiest and most pain free ways of doing things.
Walk up to a forest stag live weight lets say 20 stone[small] and you have two choices. the first is to spend ten to fifteen minutes and have the animal clean and ready for the larder and a good 6 stone lighter.
or Second, find a suitable tree, drag the 20 stone to the tree, get the hoist in place and then get the animal suspended, if there are two of you and both young and strong you will succeed, but at what cost?maybe just maybe you'll get it done in time, but almost for certain you have taken longer than vets recommended time limit for evisceration. I can understand it if you drive to your kill site, shoot the beast and use your truck to help you hoist the animal in some way. And as for the hoist on the back of a 4 wheel bike/quad, don't talk silly, you then have to go and get a tractor or gang of people to put it back on its wheels.. NoI shall stick to getting them done on the shot site and finish up at the larder and KNOW in my heart that it could not have been done better.
