Hi all. New to the forum. I have a 1023r and recently purchased a ST sprayer from my local JD dealer. I conveyed that main criteria were: 1) the need for a pressure controller based on some assumptions below, and 2) a boom. I was directed to the LP20840. When I finally got around to installation, I discovered my model does not have the pressure controller. That would be the LP22886. They offered to swap and charge me the difference in price. The upgrade would be $965+300 (for the optional boom) versus the version I have at $860 (includes boom). So the upgrade would be another $400. Disappointing, since probably I would have chosen an off-brand instead of $1265. But now I'm stuck...expensive version that does what (I think) I need, or a less expensive version that does not.

I maintain ~1 acre with some moderately steep hills and many overlapping turns. My searches strongly suggested having pressure control to adjust the amount of chemical on the fly to prevent over-applying fertilizer or weed killer in overlapping areas. Also, I will need to adjust my speed on sloped areas. Without the pressure controller, I cannot compensate.

Did I come to the correct conclusion the first time? Looking for recommendations. FYI, I'm not an experienced tractor driver, so that might play into things.

Thanks,
Mike

I have the 45 gallon three point sprayer with the pressure control valve. I find it to be a good quality sprayer. They a definite step up from your 399 fimco but not as nice as say a Hardi unit.

Typically you dont adjust the pressure on the fly. You use the pressure to adjust based off what you need. If you need the full width it will need one pressure and if you want to shut off part of it for a narrower swath you will need to adjust it.

20 PSI is considered the best PSI for droplet size and drift control.

You would be better to adjust your speed via volume than PSI. My unit runs 40 gallons out over an acre at 2mph or 20 gallons at 4mph. I will adjust my mix based on conditions.

For example...

I go to spray 1/4 acre of yard for weeds. Its flat and I can spray at full width. I adjust my sprayer to 20psi and add 5 gallons of water to the tank along with the herbicide. I then spray the yard at 4 mph measured by a GPS app on my phone.
