I think I might attempt to build a Boom Sprayer Tank to mount either in the back of the RTV 900 or the 1000-5. I won’t use it to spray any chemicals. Strictly organic . I really need to treat my orchard’s soils with nematodes to combat my Japanese beetle issues. Only a drenching of the soil will work and so far I’ve got about 3-5 acres in production. So, it’s nothing I wanna do by hand. I already have a 26 gallon tank, a Sure-flo pump and I can get the rest of the parts at northern tool. I might work well for foliar spraying as well. At some point in time and soon, I need to get a backpack blower- sprayer/mister especially to treat my peach trees. Something like a Stihl 200, 430 or, the 450 which will apply both liquid and powders. ......................
