I gave myself a wood chipper/shredder for Christmas. Using a chainsaw is easy. It takes about ten minutes to do most of the work in shaping a tree. The hard part is loading up the green-waste container - cutting the branches into pieces that fit in the bin then carrying the bin out to the sidewalk. And there's not enough space in the container, so once it's full, I either have to wait until next week to fill up the rest of the cuttings, or ask my neighbor across the street if I can use her container - repeat lugging container, clipping, filling the container, etc. Loading the chipper is easier work, and I end up with mulch that I didn't have to pay for. larger branches, of course, still have to go in the green-waste container.
All's quiet now.
