Sir;
I have a 471, 4WD, shuttle, FEL, etc...that I have had a little more than a year. It has around 200 hours of hard pulling on it, and I have had nothing but minor issues that I've mentioned elsewhere, but will sum up for you...
by the way - when i say i've worked it hard, i mean it - already tore one front tire to shreds, caught a stick in the field that broke off the dipstick tube, and scratches aplently. but it ain't no showroom ferrari after all..
anyway- there is a roll pin that connects the shuttle to the trans - it backed out due to vibration - fix involved putting tie wire through and tieing it..one issue with wiring that made the tractormeter inoperative at cold start...
yeah that's it. of course, regular things happen - brakes need adjusting occasionally, lift arms need adjusting, etc.
