Have a 743 that will start bucking if I go over bumps. I suspect that the drive chains are loose and understand that they are not adjustable. the controls are a little sloppy, so I may be contributing to the effect because once the bucking starts i may be moving the controls due to the bucking making things worse. my concern is that I will break something. So on a 743 with 2800hrs would you suspect the chains are causing the problem? fluids and filters are good, engine runs good. thnaks for your help.
