This is an aluminum frame made so you can buy the parts to put your own sprayers together. I can sell you all of the parts as well. The listing is for the frame only, not the tank. I use these for my pest control business but they could be used for weed spraying as well. I can also build you a complete unit with two electric pumps that’s made with all the top-of-the-line equipment. Very reliable set up. $500 for the frame.
