Re: [Apple-Crop] sprayer calibration debate

Hello all, need some healthy practical advice on sprayer calibration. Specifically air blast sprayers. For decades we have measured a block of trees to determine acreage, sprayed out tank and determined gallons per acre based on what area was covered in tank. For example trees planted at 8 x

Re: [Apple-Crop] sprayer calibration debate

Since I upgraded my tractor this winter, I plan on recalibration and this is the method I plan to use. Adjust the nozzles and the tractor speed until I feel I get adequate coverage of the trees. I will then fill my tank with 50 gallons of water, and spray it over a prescribed route. When the tan

Re: [Apple-Crop] sprayer calibration debate

Hello John, I think it is a little tricky to make a formula, so I have made up a simple Excel spreadsheet. If you are dealing with trees at 18 x 8 as you say, then you would drive 2408 feet to spray your acre of 331 trees (8 feet x 331 trees = 2645 feet - I have adjusted your figure of 300 per a

Re: [Apple-Crop] sprayer calibration debate

Hello Hal, I don’t think an additional respirator should be needed. After all, the respirator in the tractor cab is the same design (only larger) than the one on the oral one. Regarding the theoretical calibration of sprayers, whenever an inspector tells me they to do it with water, and to apply

Re: [Apple-Crop] sprayer calibration debate

I have done something similar to Con.  A spreadsheet factoring in the various blocks row spacing and TRV dilute gallons per acre.   I have found ground speed to be an effective way to make the necessary adjustments.   In one block I idle along at 1700 rpms and move enough air to get good coverag

Hi there...I've been trying to get this posted onto your site. I don't believe it went through as expected as I recieved a Mail Delivery Failure notice. Can you help...sorry I am not very tech savvy. Caryn

Re: [Apple-Crop] sprayer calibration debate

Hal, Question. As an enclosed-cabbed tractor ages, will the seal around the doors wear out, or better yet, how do you verify the enclosed cab is providing the protection you are after? That might make an argument for wearing the respirator in the cab, at some point during the life of the t
