i need to take down a 7 1/2 foot wide cottonwood this thing is wider then my dodge by about a foot and i dont think my CAT payloader will do the trick this time, and my saws not gonna cut it. What do you think the min size saw i should use that would be easy to find. the tree was hit by lightning 2 days ago and is still burning so hopefully by the time its done it won't be as big.
