Why Was This Mower Vibrating? Broken Blade AND Blade Adapter.

I have seen alot of things broken on mowers, but a broken blade? yes if you hit something extremely hard blades can break off! In this video i replace a blade and adapter on the Free Craftsman mower from part 1 :)

Good catch! What's up with the impact gun you're using?

[@TheOutdoorPowerGuy]

Impact is a Milwaukee 3/8 M12 stubby. not even 6 months old and i recently had to send it off for warranty repair. that's why there's a green sticker on it.
