SAWZALL Cuts Roots - No Roots In My Trench

In this video, I'm using a sawzall / reciprocating saw to cut roots out of a trench. I had to dig a trench in order to move around some electrical wiring. Through the trench digging process, I came upon some serious roots that had to be removed.
Using a chainsaw will just ruin the chain. A shovel won't work, and with an axe,... I'll be at it all day with an axe.
I had a lightbulb moment.... I'll use a sawzall!!! Aha!! That's the way to do it!! Using a sawzall was definitely the way to go. It turned a seemingly impossible job into nothing.
