I use a echo also. I dont pull the guards off myself. Having used a walkbehind unit I will say this. If its a job where it hasnt been edged in 3 years and is in real bad shape a walkbehind unit will shine. But for weekly maint IMO a stick edger cant be beat. I can edge about as fast as I can walk generaly. For what its worth I HATE edgeing but it really sets a property off and is a very important part of a detailed job. If I only could have one of the other I would get the stick edger.
