Yep, thats exactly the hook up I had, I just slipped the little roller pump over the PTO shaft, connected the chain and killed a boat load of mosquitos. This sprayer rocks, I swapped out the pressure gauge that came with it with an oil filled one, the one that came with it didnt work and looked a bit cheesy, other than that I love this sprayer. has anyone heard of a solution thats made just for washing out the spray tanks so you can go from herbicide to bug killer without killing the landscape. Also, Is that a filter thats under the tank?
