I used my 20 gallon garden sprayer with a 3gpm pump to fill the tires on my Mahindra 2810. Got the adapter from TSC for about 10 bucks. Putting 40 gallons of WWF in each tire, the total cost was about 100 bucks. Took about 2 hours total time. I still use weight on the 3PH when doing heavy loader work, but for plowing snow the loaded tires seem to be just enough.
