Tractor makers don't seem to think fenders are very important. I think they should be as solid as a rock. They arent. I think old Mr. Deere and old Mr. Ford would puke if they knew the fenders on their tractors are now plastic. Mr. Kubota should do the same, because his metal fenders are so puny and wimpy that they flex excessively when you grab the fender handles to swing your aging carcass onto the tractor.
