West Central MN | Everything I have read says it is fine to let it freeze.
We have two tractors and a combine which we will be parking for the winter with full DEF tanks. We also have about 200 gallons left in the tote and that will sit in a unheated shed all winter as well.
We DID remove the pump from the tote and put it in the heated shop as the local dealer said they have had issues with the pumps freezing and cracking. | |
