I saw a Kubota heading down the road in front of me yesterday. I caught up to it to have a look. An L48 on a drop axle trailer. As I approached, I thought the rear was a dovetail, but it wasn't. As I watched, I realized that the trailer had to be a 7,000 pounder. The rear of the trailer was flexing as they went down the road. I wonder, with the tractor, loader, hoe and loaded tires if it was overloaded. It trailed fine, but the flex in the back, behind the axles made me nervous.
