We use our little lawn tractors more for moving things around than we do mowing, their biggest failing point is the lack of weight over the drive tires. I decided that since mine had flats on both rear tires that I would install heavy puncture resistant tubes in them then maybe this summer I will replace the tires with Wider more aggressive tread ATV tires but in the meantime why not water fill the ones on it to add some much-needed weight where it will do the most good.
For this I needed an adapter to connect the garden hose to the valve stem. Milton makes a female air plug that fits the quick connects which had the .305-32 thread which fits the stem. somehow I happened to have one but don't ask me where it came from. I took a Hose bib that had a 1/8" NPT outlet for an evaporative cooler line to which I threaded in a 1/8 inch brass hex nipple then bushed up to 1/4NPT and installed an air hose quick connector. I mounted the tires without putting any air in the tubes. Instead of airing them up I watered them up to seat the beads and bring them to the hardness I wanted. The adapter allows for insertion of the valve stem through it without the need to unscrew it first but to do that I had to modify a cheap core removal tool by grinding away part of the handle.
There is right at 9 gallons of water in each tire this adds a significant amount of weight right where it is needed most
