Yes, I saw that and replied to you there.
Back to topic...
I would think you would start with the softest shear pin possible in testing to protect your expensive investment in implements and tractors. If the softest works, go up a step. If that works, go up again, until it breaks. All the while making your scientific measurements(of which, I am not familiar). If you started with the strongest shear pin, you could potentially break many implements and/or tractors before you got to a shear pin that would work correctly. I'm no engineer, but that just seems like common sense. Shear pins are dirt cheap and implements and tractors aren't.
<font color="blue"> You need to make it the shear bolt the weaker than any component in this combined system. But, not much weaker as you will not want the bolt broken frequently even when it hits a small stone. </font>
Yes, the shear pin is the safety valve that protects your implement and tractor. How much weaker it should be than the rest of your components is a big question. How would you measure something like that? I'd opt for replacing shear bolts more often than risking my equipment. Pushing a machine to the max all the time is asking for an early retirement of the machine.
