I have seen harvesters transport them before without the outside dualls, that Donahue trailer I e-mailed you about would be fine I dont see why you couldnt put your machine on the trailer then pull off the outside dualls. The only thing I could see rough about this is your tires would be a ways off the ground and you may have to muscle them around a little on and off wich could cause a bit of inconvenience but I am sure it could be done. If you would like give me a call at (307)850-7271 ask for Shawn I will try to help you in any way possible. I have a friend from Missouri who is giving up the custom cutting business and he has a Jantz trailer he is selling but he wants quite a bit more for it, give me a jingle if I can help any more....
