[QUOTE="bird dog, post: 1633534, member: 5381"] Spraying works best for me putting out about 15 gallons of mix per acre. Try to calibrate to something close to that. About 4 MPH is about the best you can do on cow pastures. My sprayer is 330 gallons. I set my speed at 4 MPH, My pressure at 30 PSI will cover 30'. This will get me right at 22 acres per load. I adjust my chemical amount to this setting. Early in the year when the weeds are young and tender, you can get by with about a pint per acre or a 1% mix. As the weeds get taller and stemier, your mix ration has to go up. The HL products go a little further. There is a little bit of trial and error when starting out even when everything is calibrated correctly. My only real problem is keeping the right speed, pressure and application rate correct as the pump starts to wear out. When the pump starts to weaken, I can run at a higher RPM to hold the pressure, but then the tractor goes to fast. I need a lot more speed settings than the 8 that I have. One thing about it, you will know in a few days where you have missed. [/QUOTE]
