Clembart that machine looks brand new. Nice job. Your tractor is shinning so much at first I did not even notice the dog sitting shotgun.
Once I get my machine (hopefully by the weekend) I am positive I will also clean it. The John Deere site mentions not to wax the bonnet, saying it can damage the plastic, it seems you guys are having no troubles. Although when it comes to cars Wax is not needed unless the car is for show. Wax melts when it gets hot, not really the best thing for car paint finishes. A good polish will always be more suitable for everyday driving type of cars vs. waxing.
Either way I think the JD line up looks so good you almost have to keep it nice and clean to match the style
