By finish mower, are you referring to a three blade rotary, or a flail mower? I have mounted a 6 foot flail onan 8200, and not had any problems at all. As a matter of fact, the guy used it to keep his grove cleaned up. He wanted it to look great, and it worked very good. Thing is, it is very heavy, and if you don't have a front loader, you might get some power steering. There are suitcase weights available from Kubota that you can mount on the front bumper. They weigh 55 pounds each, and I think you can fit five on yours. In the past, you would take this front bumper off to mount the loader, and the bumper would become disposable, or just another item in inventory. So, we have taken the old ones, and cut them down the middle and welded them to the other bumper on both sides to add another four weights. Works well to keep it down in the front.
