Ok, let me preface this by saying for 30 years I have driven semi truck and run heavy equipment, the vast majority of that time driving "lo-boy" hauling off road heavy equipment. In that 30 years I never had issues like this, today hauling my Bobcat 600 on a car trailer behind my pick up truck the unthinkable happened to me. It fell off the trailer, never in my career with several million miles hauling equipment has that came close to happening, and to do it with my personal vehicle. I know in hind sight what happened and why a strap came loose and un hooked allowing it to roll back off the trailer, my fault and I accept responsibility. It fell off at about 40 mph. rolled along on all 4 wheels right behind me and gradually drifted into the other lane and went in that ditch. It came to a gentle stop with no apparent damage, thank god no one hit the thing. I do have a question for you guys, the 600/610's freewheel and roll easily with out running,do you think they can be damaged by high speed? If you think the drive chains are noisy in your driveway, you should hear them at 40 mph. There doesn't seem to be any damage that I see yet. However I am concerned about the speed it went "over speeding" things in the drive system and the shock of it hitting the pavement off the trailer, although the drop is only about a foot or so. Has any one else ever done anything like this and if you did, what happened, especially was there any hidden damage that showed up later. I am going to keep a eye on everything like wheel seals, any new noise from drive chains & clutches etc. but hoping somebody might have some experience in having one roll that fast. Even if I wrecked the old girl, I feel so incredibly lucky nobody was hurt or property damaged! I just cant believe it was me, I do this for a living with out any issued, maybe over confidence and complacency. Take me as a lesson, it can happen to any one.
