What EXACTLY happens to your TRIMMER with GUARD OFF - Science Experiment!

You can find tons of content on this debate. However, at Main Street Mower we did not just want to give you our thoughts. We want to give you the numbers behind the science of it. So tune into this crazy experiment video, where STU and Chip attempt to BURN DOWN a TRIMMER engine.
