If you're using a hydrant for water supply there is a device called a dribble float that keeps water seeping so it doesn't freeze. Downside to this is the tank will overflow and cause a mud hole, but the tank doesn't freeze over.
I had to replace the driveshaft on my HPX Gator after 13yrs!! The knuckles went "out". Does anyone know if there is someone that would rebuild these Knuckles/ujoints? They are not like the regular joints on a pto shaft.
