I'm spraying my corn and beans but I think the application rate is maybe a little light.
I was taught 5mph, 30psi equals 10gal/acre, now go dump in the chemical and go. Easy.
Except I misplaced my monitor book so I know my speedometer isnt set right. So I just did timed runs with a stopwatch and determined for 5mph I want to the speedo to read 5.7 or 5.8, but that is about 2100RPM in 2nd gear and for some reason my pump has only been achieving 23-28psi in that range. 1st gear doesn't get to 5mph, 2nd has too low an engine speed to get the pump to pump enough pressure. I bought a new belt because I thought if it was running closer to the outside on the crankshaft pulley that would make the pump pulley spin faster for more volume/pressure.
So--if I can't make the 5/30 formula work, how do I adjust for proper rate? I have a 4 speed manual transmission in my spray coupe, a pressure-adjust switch, 8003VS TeeJet nozzles. I tested the nozzles and found that in the 30 seconds it takes me to go 220 feet (5mph), each of my 36 nozzles is putting out 17-19 (18 average) fluid ounces.
So I'm estimating, I'm putting on 16.67gallons of water / acre, and that out of my 200gallon tank comes to about 12 acres.
Is there a nozzle chart somehwer so I can adjust my speed and pressure to get my exact rate? Thanks!

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
