:1221: I don't know why anyone who took the trouble to load their tires would want to drain it come spring and do the same procedure all over again come fall. Mine were loaded when I bought it new from the dealer over 8 years ago and will stay that way hopefully till I trade up :kens:.
I put new AG's and V61's on my cub Super last year and loaded them with WWF front and rear. I run them year round and love them. Rolling Velcro. My place is hilly and the tractor feels so much more stable with that weight down low.
There's no point in not running them loaded. I loaded the tires on my Ford and it's a lawnmower, sitting under a tarp now for the winter. It really helps with stability and traction. The less you spin on the lawn the better. Plus, I can move disabled vehicles with it too.
