The Fimco 25 gallon deluxe sprayer with 10' boom and 15' hose is under $500. I figure I could mount it on the frame of my Exmark TT 60". The manual says it has a 26' vertical reach, so it probably can handle most of our trees, including all of our fruit trees. It is under $500. Is it an ok unit or just something that won't hold up?
