Depends on what type of edging your doing. Just a note but the STIHL MM55 also offers and edger attachment. And STIHL usually offers the unit in the spring standard with the wheel kit. I personally have one of the machines for tilling and looking at getting the edger atttachment. I love this unit, has many uses easy to use and plenty of power. Double handlebars make it comfortable and easy to use as well. Still think I would like a stick edger for quick maintained jobs though.
