I really need to upgrade my spray equipment before this coming spring if possible. I have a Shindaiwa spreader, Echo gas 5 gal. BP sprayer, and a pull behind unit from tractor supply. This stuff will get the job done, but is really not ideal for bigger yards. I have considered the ride on units, but they are a little more than I can spend right now so I am looking at skid sprayers. How much area can I cover with a skid sprayer? I guess my question is, how long of a hose can you use? What do you do if it won't reach all they way around the back? I really don't know of any other options. Thanks for the help.
