What are you guys using for shear pins in the pto shaft on a WD? Don't seem to have room for a nut on a 1/2" bolt on mine.

I learned the hard way not to use a bolt as heavy as a Grade 5 when I bottomed out a 5-foot rotary mower on a stump -- exploded the PTO box just about off the transmission. I can't find Grade 3 half-inch bolts through any of my local sources, so I use Grade 2. I buy in bulk because, with the same hole warbling mentioned by someone else, I replace a couple of bolts each summer. But, replacing those bolts is a lot less expensive than replacing PTO boxes.

We always used grade 5 bolts, grade 3 may be softer but don't shear correctly on impact.

I use a grade5 1/2 inch bolt with red locktite.
The hole in the pto shaft is wallowed out and chews the bolt in half given time. I have since found a newer pto drive but haven't got it on yet.

Thanks. I actually was thinking of using some mild steel 1/2" rod and drilling the ends for wire to tie it in. Or maybe hot riveting the ends. I don't expect to do any heavy pto work, maybe a sprayer pump.

I used shoulder bolts from a harware store that has an extensive stock of bolts. He said it was actually an axle bolt for a toy wagon. (Like a radio flyer).

It is kinda a special bolt. Half inch bolt with 3/8 threaded end. Lets you clamp it in tight to the shaft without trying to clamp down on the shaft itself.

AC and lots of aftermarket places handle this bolt.

Even with an Original shear-bolt, I drill both ends, so I can safety-wire them in. If the bolt does shear, an end is not going to slip out and jamb against the case.. Never thought about a Lawn Mower spindle bolt...!! Good idea..!

Today's Featured Article - Major Problems - by Anthony West. Following the aquisition of the two Fordsons to my collection I found that I was struggling to move them about. I had considered the possibility of driving the "F" to and from shows but anything other than local rallies was totaly impractical due to its sedate pace. I had also considered buying a landrover and trailer, but the price of a ... [Read Article]
