i have a three wheel edger that i use on sidewalks. I do edging once a month for 9 of my customers. while i'm edging the dirt gets kicked up and covers the sidewalk in front of me. so when i get to that part the tires mush the dirt into the sidewalk and i can't get the marks off. After i clean up and blow the loose dirt off, there are ugly tracks where the tire was. Is there anything i can do to stop this!? should i look for a hand-held edger or what? what do you do for edging?
