Winch or wench. I better stay away from the latter. Honestly, using a winch would probably, under certain circumstances, be a bit better. It would probably make my back feel better - but, OH, my God - the extra work and time required to use a winch. Dragging that winch line out and connecting to the trees and then coming back and operating it.
At least for now, its easier to just take my time, be VERY careful and drag out by hand. Biggest danger - pulling as hard as you can to get a fallen tree out and trip over one thats under foot. Done that so many times - getting very skilled at falling and ending up with only scrapes and bruises.
