Strike 2 on Google and the JD parts site...Wow I couldn't find squat on the Google!
My search of Google mentioned the same thing - a hanging weight for a 6600 combine. Unfortunately that shows on the google search page but when I go to the link it is not there.Ok, I'll be more specific. They go on the rear axle of the model 6600, 6620, 7700, & 7720 combine, or, they would make great boat anchors.
