Illinois Gleaner,sounds as though you may have got off lightly.You are lucky you weren't travelling down the road at full tilt.Some time ago I was travelling down the road, not quite at full speed, when without warning, my R72 turned a whole 180 degrees, throwing itself on a fence on the verge up against a big Box Tree stump.I didn't know which way was up, as this all occurred in a split second.The 72 had its bum on the ground, what was left of the back axle strewn out behind it, a back wheel up through the floor of the engine bay,every panel from the bin back was creased or torn. The axle appeared to have let go toward the end, on the box extension, along side of a weld. The rest of my harvest, that year was done in a green machine, as I didn't see mine again for six months, while it had a major rebuild. Part of my maintenace regime now, is to check this area of the axle whenever out of the cab. Have considered inclusion of spare change of underware as part of tool kit. I have heard some talk that this is not an isolated incident in the Agco Gleaners. Would be interested to hear if others have had this same fault.
