I'm relatively new to the tractor world. I've stepped up to a larger tractor (3025E) I had a much older super A for many years. Always liked to tinker with her. Anyway, I noticed my overflow/engine coolant fill level seems low. What does JD reccomend for coolant brand? Yesterday I turned 20 hours. Also on my pre use inspection, I noticed my left retract hose for my bucket tilt was loose. I live in northern Michigan and have only used it so far for snow pushing. Is this something I need to be checking more often? I found it odd to be loose in the first place. Thanks in advance.
