I'm looking for a used Ground Logic or Permagreen. Currently I just use a skid sprayer and on bigger weed application put the tank on my zplug. This year I would like to purchase a dedicated spreader sprayer that I can haul on a rack behind the truck.. Anyone have any leads to where I could find a unit? Craiglist and Ebay isnt working out. Looking to spend around 4k and willing to travel for the right deal.
