Not trying to talk you into the liquid route. I understand your reasoning. I had a flat recently but being the cheap skate I am I patched my own tube. I do have tubes. Lot of folks here in east Texas do fill tires. I'm looking for traction and not loader ballast. I never have occasion to use my loader without an implement on the back and my loader stays off my tractor 50% or more of the time. I do gardening and mowing in tight situations and my loader is in the way. Have a quick hitch for implements so can change quickly. I will be interested to see your end result and amount of weight and how you mount it. :thumbsup:
