. A year or two ago I paved our 1300 foot driveway and that has obviously cut down on the dust dramatically. At the end of my driveway I still have about 1300 feet of dirt / gravel road before I'm back on pavement. I have a 30 gallon tank and a carrier that it can go in behind my tractor. I was looking at the bar sprayer attachment an Tractor Supply. It seems like it would spray a 5-6' wide path, so a couple times back and forth and I would be able to cover the width of the road. I'm wondering what fluid would be best to spray.. and what would not clog the spray nozzles.. our town uses magnesium chloride on all its dirt roads here and it seems to work well. Anyone else have options ?
