I love my Yard Machine edger. I was using a Ryobi edger that made my back hurt. This Yard Machine doesn't give my back any problems. It is just like pushing a lawn mower.
This edger is very easy to use and gives my yard a manicured look. It has 3.5 HP and runs on gas. It has six position depth adjustment. This is easily adjusted by a lever. I always use the lowest setting and never change it, though. It gives a real deep cut and my yard looks great.
I have had this Yard Machine for about a year and a half and have never had any problems with it. If you want a well manicured lawn, this is a must buy and it will save your back from many aches and pains.
