Questions

I have several tractors that I need to relocate 330 miles from my family's place to my place. I want to reasonably max out load weight each trip. Since "pounds count" do you have a more focused weight for this specific tractor? The dimensions page for the tractor provides details on weight ranges. In the case of the 8N, that range is between the shipping weight as published by Ford, and the operating weight as University of Nebraska measured it on their scale. If that particular tractor you are moving has fluid in the tires, then a ballasted weight would be more appropriate (4,000+).Reference
