I bought a small bag of soft #2 grade 5/16" x 3 or 4" bolts for shear pins .
Like Dean said , you want soft bolts that will shear . A ten cent bolt is cheaper than a $300 gear box .
I quit messing with nuts on the bolts . If a pin shears I use the new bolt to drive out the old bolt , then I bend the threaded end ( maybe 20 degrees ) by hitting it with a hammer . The bent bolt does not fall out and I did not have to keep up with wrenches and nuts .
For safety I always sit on the tractor until the blades stop spinning before I get off .
Two things to put on your XMas list , for about $100 you can get a clutch that fits between the drive shaft and gear box so you will never need shear pins again . Second is a live hydraulic set up so you can pick up the cutter with out having to ingauge the pto drive ( and spin the cutter blades )
I was down by the pond cutting when the pin sheared . I got off and replaced the pin . A few minutes latter I realised there are lots of chiggers around the pond . Now I spray my pants legs before cutting .
