Ixero I Got the cover loose and off-even the four bolts at the back which looked impossible...I cut the two ears off of the steering box..It would not possibly come out without doing that, or remove the whole seat platform etc....No sign of broken weld inside the coverNow what do I look for?? Note: reason for going into gearbox was Pto spins when lever is all the way forward--all the way forward should be lift but no pto turning. Had to crank tractor with pto engaged--crank without pto engaged and you can't engage it later-it grinds... Thanks
