    i noticed weld fatigue on the bar that the lift cylinder attaches to on the tower. has anyone else had this same problem? looks like one one side the fatigue starts where the weld ends and goes about 1/3 of the way around the bar. the other side the fatigue starts where the weld metal gets thin and works its way around about 1/4 the way around the bar. looks like i will need to weld in some braces.

    heres some pics that The Boss resized for me. Thanks again.
    The top one you can see where the fatigue is starting and seems worse, that is the drivers side. the other is the passengers side and isnt as bad. luckily my plow hasnt gotten much use since it hasnt snowed much. More projects for summer it looks like. :)
    i talked to the local boss dealer and they said they occasionally see the problem but not often. i know it was caused by me going alittle fast and hitting bumps which can stress the plow alot.

    Maybe my eyes are bad but that just looks like surface rust to me?

    i was hoping it was just rust so i asked my welding instructor at college and he agreed that it was fatigue. he is also a weld inspector with more titles than i can remember.
    you can tell cause the metal is getting pulled down by the plow bouning when i drive. it is stressing the metal, since a weld is stronger than the surrounding metal if done right. hopefully it will last the rest of the season.

    Can you run another bead around there?

    the best thing would be to weld some gussets and a piece of flat stock across the top of the bar. i could also weld another bead which might be a good temporary fix. good idea boss.
