I've got a lawn service that is naturally branching out into more and more landscaping. We've always hand cut new and existing bed edges, but it's just plain ol getting old. Time is definitely becoming and issue as we do more landscaping. My problem is, I'm kinda caught in between at this point. I don't really have the amount of business here to justify a 2000 dollar machine yet and my landscaping jobs aren't always consistent so I can't line up a bunch and rent a machine for a day. My question is, can I purchase a straight edger for a stihl weedeater and fix a blade like a trenchblade to it and expect to cut a deep quality edge. Or will these trimmer attachments only redefine an old edge. I've also thought of buying and inexpensive smaller edger like a craftsman machine and putting a blade on it. I'm not gonna take the plunge and buy a Brown edger yet, I've got too much cost into equipment this year, so I'm only looking of ideas that work with this situation. Any ideas, questions, or suggestions would be great appreciated.
