Ok, I bought a brand X mower, A Slasher, probably Chinese from a local dealer, they have since moved and am having a hard time finding them or parts. The mower has worked well, it has had to undergo some small fallen logs and small rocks. And it just had a couple chips on the blade. Today I hit a larger rock and it seemed to bend one of the mower arms, now it vibrates so i can't use it anymore, looking around I can't seem to find new arms for it. They are small, 13 1/2 inch from center hole to end and the hole is about 13/16 inch where it attaches. I am thinking about taking it to a machine shop and have them bend it back, think that will work.
