My son and I started a lawn care business this year. I wanted to teach him good work ethic and also give him a chance to make some money. We have 3 weekly residential customers and a couple that called us to mow while their equipment was being repaired. We started out with some basic residential equipment. 21" TroyBilt mulching push mower 22" YardMachine side discharge Worx string trimmer I just purchased a Better Outdoor 36" Quick dual hydro Samurai. I'm looking for a commercial trimmer/edger combo any suggestions?
