I have decided to not use my FEL anymore until I get the rear tires filled. The tractor is just too tipsy. It nearly tipped to the side this weekend when I was using it. The bucket had more dirt on one side than the other. I barely raised the bucket to dump, and it nearly tipped over to the right. This is a really scarey feeling. I had my seat belt on tight, but I know that this is too dangerous of a situation. If I were a dealer I would NOT sell this tractor & FEL without filling the tires prior to delivery. I'd be afraid somebody would drag me into a lawsuit from a roll or tipover from the light rear end. I know the manual eludes to the point of filling the rear tires, but it is not emphasized as much as it needs to be, given how easy it is to tip over. I mounted my 5' box blade on the back, but that is still not near enough rear weight for the 6' bucket on the 4110. The bucket seems a little large for that size tractor anyway. Most tractors in the 4110 range that I have seen have only 5' buckets. So, the 4110 with the ML112 loader with 6' bucket really needs rear weight to be safe. Maybe some of you guys could educate me better on this topic, b/c I admit I'm new with a FEL.
