Taking this to yet another level .. here's a video on one of the big daddy's of chainsaws ..The Husqvarna 572 XP .. Not just in cars does tech and computers play a huge role ..If you can watch it until they're pulling the saw apart to show the innards but wait til they whack it on the diagnostics ..Quite incredible .
This is a fully pro saw though ..not meant for the backyard and a Saturday morning wood cut necessarily .. Enjoy ..
