I made mine from a pull-behind that I bought for yard use. I originally used it with my zero turn mower but I was spraying for behia grass in a rough area next to my front fence and bent the tongue so I just took the tank off, made a frame from 2x6s, and mounted the tank on that. I used the original brackets to hold the two spray nozzles and made sure that fitment enabled the spray to clear the open tailgate. A long wiring harness lets me connect straight to the battery on my Ranger and a rocker switch allows me to cut it off or on at will. It works so well I now use it on narrow or very small food plots.
