Thanks! But I don't want to get too cocky until I see how it works in the field! It works great wetting my shop floor. I think the first time I use it will be a learning experience. I probably need to be back in the truck bed monitoring the flow while someone else drives. I think proper speed will be critical as far as coverage. And I expect some overspray, but in my situation, killing some road or plotside plants will not matter, in fact, it is desired to maybe minimize the trimming I have to do. I designed the rear hitch so that I can also attach my boom (from my little 20 gallon ATV sprayer) by only using one bolt, and the hoses will also quick connect, so if I need more accurate coverage, I can always switch from boomless to boom.
I also see the need for a 12V controlled valve. I thought i could control it from the cab by simply turning the motor on/off with a remote switch, but it tends to dribble, and that will waste chemicals. But all in all, I think it will work, and at least it has the capacity to cover some ground without having to return to a water source to refill.
I initially intended to build a frame so I could lift it with my FEL, but after some thought, I decided lighter was better. I can now load it in my truck by myself (empty of course). And I don't see the need to ever lift it with water in it.
