I was wondering what kind of spraying equipment you guys use when you are spraying liquid iron. My yards are big so I use a Fimco sprayer with boom, that goes on my gator. I know it may not be the most proffesional piece of equipment, but it sprays my pesticedes great. When it comes to spraying anything like iron it doesn't spray much out and seems to clog up. It sprays it out of the wand fine, just not the boom. I am pretty sure I have the largest screens. Do I need some sort of special sprayer to use with iron? Thanks for the help.
