normt93 Wheels are a big problem for us big bolters,It is really a downer to open up your wheels and find they are just a mass of rust and maybe too far gone to use.In the corn belt of Illinois there are a lot of AD trucks sleeping in the barn, that have often been used at harvest time then parked till the next fall. As machinery (combines) get bigger these trucks become obsolete,combine holds more than the truck. This may be good news for big bolters as those trucks show up at farm sales!!
