I have replaced all the pivot tubes,and rebuilt the whole plow before,it was 10 years ago,so the details are a little foggy.I gave up on meyer a long time ago,for that reason.I still have the plow buried in my tall weeds,maybe Ill throw a chain on it and pull it out with the loader and take a look again.I remember a lot of swearing,welding and the torch and hammer were well worn when I finished.I used a lenth of pipe ,I'm not sure,but I think it was 1",i slid it into a bigger pipe and welded all the bigger pieces in place of the original that I torched off the blade.The 1" became the pin,one big pin about 5 ft long with twice the strenth and 2 extra pivots on the blade.I never broke it again,I wish you luck,it is a PITA job.Next time buy Diamond/Fisher/Boss/Western is stronger.I dont feel the meyer is up to commercial plowing unless you baby it and dont have heavy trucks.<p>----------<br>John D<br>
