Got done last week, the Kubota made it through again. I use a M125 front wheel assist on a JD 1760 12RN planter with liquid fert. Most people don't think it will work at all, but when the rain was coming I pushed her up to 5.3mph for awhile(usually 4.8). My 20/20 monitor said I was only doing slightly worse at 5.3 which surprised me. It also used only 31 gallons planting 115 acres one day, planting corn with liquid on. What does a "normal sized" tractor use per acre? I thought between a quarter and third of a gallon is pretty darn good with this one. Sure get a lot of weird looks with this set up!!
