I bought a used 3 point Priefert bottom plow. I have ground with some blackberry roots, so I also bought a separate used coulter. The plow's moldboard is about 14" So I bought a coulter of 14" diameter with scalloped edges.
The coulter came with a mounting bracket, but I need two 1/2" bolts that pass through a 1" thick beam that runs parallel to the plow direction.
Should I buy shear bolts? If so, what rating? Or should I buy regular steel or hardened steel? I don't want to bust the linkage on the 3 point.
Thanks for the help.
