What kind of track spacing relative to boom width are guys using and how much overlap are you getting with your settings. Example, how many applied acres are you getting on a field that perimeters 160 acres?.

I'm not following what you mean. Could you elaborate?

With that track spacing, how many applied acres do you get on a 160 acre perimeter? Do you ever see any small misses when spraying in a cross or quartering wind?

There must be a way to adjust track spacing. What if you went to custom booms over 120'?. You would have to have a way to adjust for that.No way to set track width on my sprayer!

Just set your boom to be a little narrower than your coverage width.No way to set track width on my sprayer!
110' boom. I'd have to double check, but I think tracking is set for 109' or 109'6". Don't see much for misses. If the wind is blowing cross-ways, it will be the same W->E wind for every pass.....
As for acres per 160ac.....must be nice to have those square fields!

On a 120' boom, 12" lap on all chemicals except fungicides with no overlap.

Sorry for the confusion...
I overlap 12" and my boom is 110'. I have very few square quarters, but I have my distance or speed cal set a couple of points down so that my overlaps (row to row and headlands) don't create large overages. This way I have effective and complete coverage, without the extra expense of the overlaps. I've cheated the system to think it's only applied over the actual physical area. You could do the same thing by taking your target rate X an overlap multiplier.
eg) 10gal/ac x 160ac actual/164ac applied=9.76 gal/ac target rate. (using the common extra 4ac/quarter that 'wetfoot' stated in post #12)
Your application will still work, but you save most of your overrun costs on every field.

On a true square 160, with nothing to go around the lowest I have seen applied acres was 1.1 acres over perimeter. I don't know my swath control settings off hand, but they are pretty generous to avoid skips and overlap at headlands. And pass to pass I have yet to find a miss except maybe where the operator (me) didn't engage auto steer directly on line. 110 degree nozzles help too.
I have never seen a miss due to wind direction. At least nothing visible. This is all on sf1.

Two potholes and a house/yard in the corner... I am constantly 158.5 on a 156 acre field.. 89' on 90' foot booms, no auto shutoffs. And I still have people complaining.. One acre per field is common... Unless you don't mind the outside three rows not growing. I don't mind hitting trees and fence posts.

I agree but I've never found an area on the screen where it could be done.
Gotta be somewhere.
that is funny I mind it like crazy unfortunately it does not stop me . I can say though I have not had to replace a fence post since I went to a front. Boom though. I over lap 6" on 93' boom only skips I ever notice is where I run out of products and when I load back up I get in a fight with it where I actually ran out.... I would not want to spray without auto boom ever again. I do not understand guys who will buy new sprayer but will not want to spend a few bucks on great technology that definitly pays. Or maybe they are not as cheap as me and do not care how much overlap and stuff they have.Two I don't mind hitting trees and fence posts.
I custom spray and I keep records of every field I spray and what the applied ac. are if it is the first time I spray a field I will do a perimeter and if it is a square field I will allow for 4 percent more for my applied then actual ac. If there are lots of things to go around I up the percentage to be safe .i then take the gals. And divide by ac. and adjust my rate and then leave the long straight rounds to the last and when I have 5 or 6 laps left I keep tract of how many ac. are in a round and adjust gals. To make it work out at the end it has worked out for me good over the years.

My coop is know to do that, especially when they are say 200 gallons short.
My sprayer is to old to handle the updates. Honestly I would take auto steer before auto boom. I have seen overlap from auto boom where the operator was just going to fast.
