You say that, until its 6pm and you clear one tree, then find 3 more behind it. I was so glad i had a gas saw that dayDewalt 20v sawzall count?
Three batteries on board!
Disclaimer: I also have a large-toothed hand saw (think bow saw) and a smaller handsaw for brush as well.
Between all that, and as OP suggested, a winch and a lift, I think I could move a dead tree. Take me awhile, but if it's in my trail I got nothin' but time, baby!
