Hello all! I'm looking for a 35-40 gallon sprayer to use for individual plant treatment of Sendero to mesquite that I can put in the cargo bed of my Polaris Ranger. I'll only be using a spray gun, so no boom attachments needed. I sprayed 5000 acres last season (shortened season) with a 25 gallon sprayer that was older and thrown together so am looking to upgrade to be more efficient since I'm looking at 10,000 acres as a goal for this year. With the UTV setup, I drive with one hand, hold the spray gun in the other, and occasionally get out to reach more places at once. I know there are a lot of expensive options out there so I feel handy enough to build my own, I just need a guide or advice on how to do so. At the 35-40 gallon range, I think it would be a lot cheaper, but would want to build it right and reliable - any suggestions on best pumps, tools to use to attach and drill into the tank, spray gun, etc. If I'm feeling fancy, I'd get a hose reel as well. Of course, if anyone knows of any good deals or great setups out there that I should look into buying, I'm open to that as well! Thanks for the help!
