Battery tender safest bet. If you have auto start, turn the power switch off. That will drain battery about as quick as the clock if sitting for extended period.
The tow hitch is great. The only bad thing when pulling on bare ice with trks, is they will still come around "real" quick and up on top of the trks. It's not pretty. I had to run straps to each side of the atv to prevent.
One of these 2 will be my next unit.
