The Barricade is just as bad at the 1-1.25lb/acre rate. I had to leave my ride-ons at idle with the pump running between stops. Even at that the tip screens would occasionally clog. Barricade/simazine mix is even worse. I did not wear out the pump though. The one machine has 1000+ hrs on it with the original pump. However, its a Z not a T.
