I'm not sure on that, but it only takes me about 30 seconds to fill out the paperwork, put an envelope, and a brochure about the treatment in a bag that hangs on the door. we don't use ride ons. We have one, it has only been used on our own properties, I don't think that some of our customers would like us going out and charging them 400-500 dollars and being done in 20 minutes. We use Scotts spreaders when we are doing granular applications. Have you had any complaints from customers, what do you do if the ground is very wet? I have had spreaders sinking in some places this year, I would hate to see what would have happened if I were on a perma green rideon.
