In windy conditions I go as low as I can usually 22-24". Even a few inches can make a difference in keeping your spray where you want it. Might not be a perfect overlap pattern but sometimes you just have to make trade-offs. Besides the wind will mix it a bit for you. When you're low to the ground I think the duty cycle needs to be kept higher. Lower pressure to get higher duty cycle. I think that's why they recommend spraying higher with PWM. You need some buffer for the pulses to mix. Normally without wind I also run at 28" with Aim Command Pro and I've never had problems. If you have smaller nozzles you might try ltk 's recommendation of trying lower water rate. |

I’m using TT White 08. 13.2 USG. With aim command. I typically spray at 28” high. Is that too high? Or should I go 20” high. I was told with aim I should be at least 30”. I find its too high. I run my booms with the centre section as low as it will go and the wings as level as i can keep them pretty much all the time. When the wind is up I will drop the outside wing tip to perhaps 15" as i do the headland along another downwind crop and drop my pressure to as low as 20PSI (depending on wind velocity) using the wind to move the spray just enough to prevent stripping. It's a bit of a balancing act. Too slow and get stripping, too fast and you get drift into the next field. I tend to err on the side of too slow. Running my booms as low as i do may be why I have never had good luck with auto boom height. Tried too systems and punted both as they just don't react fast enough to keep the booms out of the dirt. They also tended to lift a bit when i didn't want them to leaving me at the risk of drift. MUCH more comfortable managing boom height manually. |

For AIM Command, 24" boom height is the recommended. Because of the pulsing, they want a bit of safety factor to make sure 100% overlap is achieved. (Compared to 20" which is the normal recommended with 110° nozzles. Unfortunately, might be able to count how many are able to run 20-24" on a hand or two. Most I see are running 26"+ |

When the booms are higher than the planetaries (and they often are), the guys booms look like new after several years but the neighbours crops don't fair so well. |

So, when you guys are talking boom height, are you in inches or feet??  I envy any of you flat earthers! I'm usually happy if the booms aren't dragging in the dirt or swatting at air planes. We have some rugged ground. |

I try to maintain 20-28 inches depending on what I'm doing and the Raven autoboom does a pretty good job with my slightly rolling land, better than I could do manually at speed. I do have boom wheels that do sometimes hit the ground. Definitely wouldn't want to be without them. Worst case if you really mess up and strike the ground the Patriot has full-boom breakaway which I've tripped on a couple of occasions--once the Raven autoboom sent the boom into the ground for some reason, the other time I hit a round bale while turning.

We have some rugged ground. 95% of what I farm is flat to gently rolling, the other 5% is the mountains of Tibet. I think I waved at the guys in the space station last year. That farm I run the auto boom at 40" everything else I run at 30" unless it's a bit windy then I'll drop to 24". |

inches, feet, pretty high tech. I run my booms knee level on the flats. Have any of you guys done a yield comparison of liberty burn on cereals. Most of the time wheat barley and oats grow through it but wondered what damage is caused by delayed growth. Lots of liberty and round up drift this year but I would say more round up from inversions. I wondered if the 30 plus c weather mixed with the cool nights was just the right recipe for an inversion.

Warm days and cooler evenings and mornings definitely cause inversion. Had to stop yesterday morning after one round. A touch on the windy side but was made worse by the spray rising up. Sprayed the day before in worse wind with little drifting. I always hate evening spraying, can go from borderline to windy to dead calm within a couple rounds and that’s used where the most problems happen.
About another 10 minutes and we’re done the first round of spraying!
