I'd like to try a stick edger, but I feel I should be prepared to repair any possible damages as a result. Curious...when one does encounter/mangle a plastic sprinkler head with an edger blade, how much is the repair? Do you all perform these repairs yourself? Do you consult with your customer first? How many kinds of sprinkler head parts should I have on hand to make these repairs? Seriously, do you all know (as well as your employees) where all these sprinkler heads are...or are they marked with a flag ALL year? I guess I just don't see the value in taking this risk cuz I see (or mostly know of) a LOT of pretty dang small sprinkler heads immediately adjacent to concrete edges that I SAFELY maintain with my string trimmer. Would these edges possibly look sharper if edged with a stick edger? Yeah, maybe, but at what risk/expense? PS - HAPPY MARDI GRAS!!!
