Fire fighters use it to set back fires, clear land, clear safety zones... All kinds of good stuff.
I have 25 acres and a small farm and if a field sits unused for much more than a year the grass starts to get crowded out by plants livestock won't eat so I burn it off. If also helps the soil, I burn off my garden, and a couple food plots. Using I don't like lugging a propane tank around with the wand, way to comber some and heavy for any real use. I have been using a pump sprayer for years and just starting a small fire and spraying a trail for the fire to follow but it's starting to get old. First even with diesel I know it won't explode but have a wife and son and don't want to tempt fate any longer. Second the sprayers don't last. The diesel and kerosene or gas destroy them rather quick. You have to buy the better commercial sprayers to get any kind of longevity out of them cause the O rings just don't last at all. Even then I am buying 1 a year and at $40-$45 a whack I could have bought a drip torch several times over so I am just gonna do it this year.
