Sprayer was used for 2 apps in 2013. The Eco-505 was never used, just the coaxial hose & hose reel. Unit is on a 7×12' trailer. I will sell the trailer with the sprayers for $1000 more. This is a great deal @$4000. Paid over $5500 for sprayers. Selling because I came across a great deal for a Turfco ride on.
