Good morning all, I am new to this site and I just purchased my first Kubota Tractor yesterday, it is a MX5800 with FEL installed. I was going through the paperwork with the sales department and they had an inspection check list they performed on the tractor. On the anti freeze it stated checked at -10 degrees. I was concerned with this number as I live in Missouri and the temp over the weekend is calling for -8 for the low. I questioned the salesman and he is looking into this. I have always ran about -30 to -40 on all my vehicles just to be safe. Has anyone ever noticed this or what are your thoughts. Sorry if this was answered somewhere else but getting used to forum. Thanks in advance.
