Central Nebraska | Unless you started making changes to your display settings I doubt that the problem will be solved my making changes to settings. Been there, tried that. My 4430 had a hard time maintaining rate a few years ago and we did all those things with the display. In the end the problem was that the bleed line off the top of the pump was plugged up with rust and the pump was not able purge air out of the top of itself. I also had a situation last week where I sprayed a 1/4 with a set of tips I had not used yet this year. I was set for 15 gpa and my rate bounced from 14-16. On my next field I switched to a newer set of tips with the same size oriface. My rate held perfect. Looks like I wore out a set of tips. |
