I am trying to expand the lawn care side of my business. Currently I use a 22" walk behind and a husqvarna 326L string trimmer. What is a good hr rate for that equipment? Also if I purchased a rider how much more could I charge. I live in Mendocino County in Northern California Zone 17. I understand how important it is to charge standard industry rates (or more) rather then to bring them down by lowballing. Any help would be appreciated very much.
