I recently bought a walkbehind edger. It does really great, however i have a tough time on walkways and beds that have a curve to them. The beds aren't so bad because I come back at a 45 degree angle then I take my straight edge shovel to it. Then I just compensate with the shovel. How do all you guys who use a walkbehind edger make the curve of a walkway look great? Any help would be great. Thanks.
