Hey guys I'm getting a 4630 in just a few weeks and wondering what you guys think would be some good tips for me to start with. I will be spraying mostly 15 and 20 gpa. 13-15 for burndown and mostly 20 in soybeans and corn. What would be some good tip recommendations as Im not 100% sure how this sprayer will operate and its pumps abilities. Buddy told me he uses 6's for his 15gpa and runs about 13mph. He said at 20gpa i wouldn't be able to go as fast. Would 7s be better for the 20gpa or will the pump not put out enough to run 13mph+ at 20gpa?? Still learning on all of this so any help would be appreciated.
