Military technology often gets repurposed in peace time, so it makes perfect sense that in the future this might happen to Mecha or Exo-suits. A concept that is brilliantly envisioned by Dave Kaleta in the Lumberjack 4000, a terrifying tree killing machine:

This build is loaded with play features for all kinds of arboreal mayhem, including chainsaws, axes, and climbing spurs. But I really love the through-the-chest wood chipper and Buffalo Plaid color scheme! And the choice of a female operator (Lumberjill?) is a nice touch.
