The recent "6 mile of mowing" post got me to thinking once again about the need for some type of edger that could be mounted to the side of your mower. I'm familiar with Walker's edger, but it is very expensive and somewhat overkill for the occasional long sidewalk or driveway situation that I commonly see. I'm talking about a string trimmer device that could be mounted on the side of your deck in a vertical position, driven by a small 2 cyle motor or a 12 volt electric motor. It would have to have the ability to be lowered to compensate for string wear, and there would have to be a way to index the string from the drivers seat. It would also be nice if it could be quickly installed and removed with some type of a bracket. I feel with a little practice I could control my ZTR well enough to be accurate with the cutting line of the string. One of these days if I find time I am going to try to fabricate something like this. Has anyone ever seen or done this already?
