i am experiencing the exact same problem. I have about 200' of hose running from my house to the water trough. this morning i was hauling 5 gallon buckets from the house up to the cows using my small 15hp Kubota tractor. After about the fifth trip the fuel line froze (guess i must have water in the fuel oil) so had to finish the job using my pickup truck. It looks like that will be my morning chore for the next 12 or so days, maybe longer i guess we will see.
