A better cutting weedeater for cutting Johnson grass and weeds.

My sister had started trying to get the weeds, Johnson grass and tall grass cut around the ditch to the east of her house but her weedeater was not cutting the Johnson grass and weeds very well so I thought about trying to modify one of my old weedeaters and see if I could get it to work better, this is what I came up with as a proof of concept, seemed to work a lot better. I also had my big high wheeled weed whacker and I wound up using it for most of it. Sorry about the poor video, it's hard to hold a phone and record while using a weedeater and having bright sunshine hitting your eyes and phone.
