I personally believe Good Agitation is key to any liquid application. I don't ever want find a large residue in the bottom of my tank. First thing I do when hit a stop is flip on my PTO to agitate my tank that just sprayed a lawn. The tank in my Used TG/CL truck has 4 jets and a 25 GPM PTO driven pump. TG/CL has always had good equipment just Idiots for Spray Techs. I must Mix my chemicals in a ground tank and pump them on board my TG/CL truck. Nature of the TG/CL operation and equipment. I use a 220 V Swimming pool pump which is chemical resistant. I also put 4 agitation Jets in my mix tank. The water looks like it is boiling. .
