I guess it is possible to mow, spread, and spray with one machine, but it is not the "same machine" as the z spray. I realize that the z spray is a wright stander with attachments, but consider the following. The zspray front framework is totally different. The z spray has a sweet break away boom that allows you to spray left only, right only, center only, left center, right center, and all open. It also has a spot spray hose. There are 2 fertilizer trays that hold a bag each, a speedometer, and a 120 or 200 lb hopper with a nice electric speed control at your finger tips. Yes I could have built one, it would have taken me a year and been half the quality as the z spray. For a thousand bucks or whatever they got for labor, it was well worth it.
