I just had MFA (Missouri Farmers Association) fill my brand spanking new bulk tank. With both a Bobcat and a Deere, I wanted the bulk tank not so much for savings as for convenience. MFA sells the sames fuel, just dyed if it is for off road use. I figure if all the real tractors in the area are burning it, it should be just fine for my 4410. Don't mind saving a quarter a gallon, either. Sure, it will take a lot of gallons to make up the 650 dollars for the 300 gallon tank, stand, hose and filter. But, lugging 5 gallon jugs of smelly, messy diesel fuel gets old quick and I have a lot of hours to put in on both machines between now and November.
