[QUOTE="sim.-ang.king, post: 1511620, member: 14533"] Don't cry "victim" to an argument on an internet forum that you took part in willingly. Now if you want to debate ways to pull a calf, we can. [b]The most important part in pulling a calf, is getting the calf out, live, dead, or otherwise. [/b] When you are pulling a calf a lot of different forces are taking place to remove the calf. There is the backwards pulling, the forwards pushing, and also the lifting the calf up and out of the uterus. When using just a winch to pull the calf out, or pulling in any way, if the cow isn't brace from also going backwards with the pulling. You are losing the forward movement, and in turn you lose effective pull strength. By having something to act as a fulcrum while pulling, like a calf pulling pole does, you change from a ramp to a lever. A lever will double your effective work load over just pulling. The puller also uses this lever action to lift the calf up and out the uterus. With just pulling you have to pull up and out of the uterus, and then back down. Doubling your work load once again. So the puller acts as a winch, fulcrum, lever, and ramp all in one. I once pulled a calf out in the pasture by bracing my feet against the cow rear hip pins, and then pulling with my arms, legs, and back as if I was rowing a boat. Ended up dumping the 115# calf, plus everything else, right on top of me. It worked because I had a fulcrum, my feet, and lever, the rest of my body, to lift and pull the calf out. So if winching while standing in a chute can get the calf out, well that is the number one goal. But using a calf puller may save more time, energy, and is actually safer for the calf, and cow, considering the fact that you can control the amount of pressure applied more easily. [/QUOTE]
