My dealer sent a mechanic out last night to give my B21 a once over before the warranty expires next month.
While he was here, I asked what kind of problems he has to deal with from abuse and misuse of tractors. The one that he mentioned, which I thought was most interesting, was three point hitch failure from heavy loads, like tillers and box blades when your not using them but traveling with them raised on bouncy terrain. As I understand what he said, inside on a yoke, a rod connects to the hydraulic piston and through the yoke is a roll pin holding the rod.
The pin can fatigue under impact loads, (bouncing attachments), break, the yoke/rod falls into the gears and major bucks drop out of your wallet./w3tcompact/icons/frown.gif
His solution was to adjust the lowering speed to fully closed and go slow on rough terrain to minimize the impact loading. I've explained this as best I can and I know a lot of use use box blades, among other things for ballast. Maybe kubmech or others can confirm this failure mode or better explain it.
BTW B21 is fine and dandy/w3tcompact/icons/smile.gif
