I went with the the water/ windshield washer fluid combo. A gallon of the washer fluid concentrate makes 55 gallons rated @ -18. It cost me $11 a gallon jug so I have a total of 30 bucks (including valve) to fill my rear tires.
It makes a huge difference in the way the tractor handles.
I have one of the valves that you can hook up to the hose and then have to press the relief button to let air out as you go, but my question is how do you add water PLUS another fluid like washer fluid with this setup? There is no way to draw fluid from another container is there? I would like to fill the tires on my B7100, but I don't want corrosion, and even though I'm in MS, we could still have a freeze, so I would definitely need something other than just water.
You can gravity feed it in by mixing the concentrate and water in a seperate bucket or jug, or build an adapter into your garden hose that can act as an eductor, drawing your concentrate into the tire at the same time the water is added.
i have an old garden sprayer i use. just add your antifreeze to the sprayer and pump it in. you have to take the spray wand off first however. after i get the antifreeze in the tire i add water with the water hose/tire filling thing already written about.....al
I filled mine with free used antifreeze I used one of the cheap drill motor mumps with short piece of garden hose on onside and plastic tubing on the other side that fits over valve stem. Fill tire with antifreeze mix so far then pull hose off valve stem to relieve air then fill more till full.
I would put valve steam around 10-11 position so you know when fluid is covering wheel but not full.
