il weedman - 7/8/2009 20:06 So you don't calibrate the pump with different products? How can you not calibrate it right? The system makes you shut the pump off and sit still. You do what it says and hit ok and it does it. Not a real big deal. I calibrate every time I change product mixtures without these problems. My deere AMS guy had me do this first with about every problem I had when we bought this new. Always seemed to solve it. Don't see how it could hurt. I calibrate every time I change product mixtures If I did that I'd spend more time calibrating then I would spraying. Someone told you a very big fib!!!! You do NOT want to calibrate your pump that often! And DO NOT calibrate with anything other then WATER! Only time you need to calibrate is after changing the pump or motor.
