Never heard of a grenade. Wow, great time for this post. BF is using a splitting wedge, axe, sledgehammer (when axe gets stuck) and chain saw. We have 6 big trees that need to be cut up and 2 more that are partially cut up. Storm came through and damaged a bunch that we discovered the ants had already gotten to and it was just a matter of time before they fell. One fell on the house. They look small in the picture because there is nothing for perspective, but trust me they are big ones. I just do the picking up, wheelbarrowing, stacking, sorting and getting branches out of the way.
Here are 4, some black locust, hopefully we'll get more fence posts from them:
Here's another big one with all the branches piled up that haven't been dealt with yet. Had just get them out of the yard first. Each branch pile is taller than a person standing up.
Here are the 2 partially cut up black locust that run down the length of the driveway in various stages of chopped-up'ness. got 63 fence posts out of this one!
Just for fun, this is what one did to the house, they were all this tall and it sticks way out over the other side of the house. Getting a new roof out of it though!
