Hope this helps
To fill the tires do the following:
1. By a pump that connects to a drill, about $6.00 at HomeDepot
2. Go to the autostore or tractor store and get a valve for the filling tire with liquid. It screws onto the valve stem, and has a garden hose connection on it, about $6. Remove the valve stem from the tire and remove the air from the tire.
3. Connect the gareden hose to the pump, and from the pump into a 5 gallon bucket.
4. Pour the windshield washer fluid or what ever your choice of fluid is into the 5 gallon bucket.
5. Turn on the pump via the drill and fill the tire.
6. Keep the valve steam at the 12 o clock postion when filling.
7. Stop after the first 5 gallon and let the air out of the tire, the pump put in.
8. Repeat until the tire is filled about 75%, remove the valve steam keeping the tire at 12 o’clock. When you do not get fluid out, the tire has enough.
9. Put in about 10-15 psi of air into the tire.
I filled about 10 gallons into a tire in about 15 minutes using this method, also you need to remove the valve assembly, and then repalce when done and put air in the tire. You may also want to jack the tractor up to take the weight off the tire if you do not remove the tire from the tractor.
