IN MHO every tractor will benifit from haveing the tires filled, Ok Jacj the tractor up AND BLOCK IT,, turn the tire untill the valve stem is at 12 o'clock and unscrew the valve body,, Now I used an old 3 gallon sprayer and took the spray wand off and breeze banded a n old needle valve in the end filled the jug with a 50/50 mix of anti freeze and pumped it in,, had an adult beverage filled the jug and repeated untill the tires were full,, you will have to let out the air the water mix take up,, not a problem,,, NOW when the mix starts to leak out of the valve stem THE TIRE IS FULL( you have to leave room for the air other wise the tire will not be able to flex if its full of mix) then put the valve back in and pump in the air to what it calls for inthe manual,, then go around to the other tired do the same thing have another adult beverage or 2 and your done,,,,, if you take the tires off they are a BYTCH to get back on once they have been filled,,this way you dont have to remove anything and dont bust your guts or other things, getting them back on
Hope one mans simple fix helps,, oh and I know some one of my tree huggin friends will say something about useing anti freeze,, it was the cheapest way I could do it,, beet juice is great but I cant afford it
