Should I buy JD Shear Pins for my 54" snowblower or get some at my Local Ace Hardware?

if you are close to the dealer, (or any hardware store) and they have a bulk hardware display, you can get them
for very reasonable cost, they are 1/4 bolts, 1" or 1 1/4" long, and if i'm not mistaken
grade 5 with a nylock nut.

If you're ever stuck them you can use s regular bolt with a nut but don't tighten it too much.
Make sure the bolt is slightly of a smaller diameter. It helps..
Now while everyone will say get shear pins etc, a regular bolt doesn't have much strength and will shear pretty easily off.. if not easier than some shear pins.
But like I said, if ever the store is closed and you're midwork.. a regular bolt can save the day.

Shear pins are there to take the "hit" so something else doesn't break that may be more expensive than shear pins. Your decision as to what to use.
If shearing too many pins, find out what is causing this to happen and remedy that problem.
I like to use lock nuts on the bolts and do not tighten the bolts, but leave them loose.

Use the JD shear bolts. The bolt is only $0.46 and the nut is only $0.25. Then you will know you have the correct bolts to shear properly.
As you know, your 54" blower housing already has four spare shear bolts mounted on the left side to the rear of the auger housing.
The JD bolt is rated as grade "A17D" which is equivalent to Grade-5

When I had a PTO driven snow blower - I used regular 'ol grade 2, 1/4" x 1 1/2" bolts. They sheared sooner than OEM shear pins - but, what the heck - they were cheep and available at the local ACE hardware. Otherwise, it was a 60 mile round trip to the tractor dealer for OEM shear pins.

I have a 54" snowblower. Here is a pic of the original shear pins. As yo u can see it is a grade 5 bolt 1 inch long.

I twisted a driveshaft because I didn't know to use the Grade 2 shear bolt. I just threw a Grade 5 in and whack, and ruined the PTO shaft. Could have been more expensive than that. Now I know.

That's got to be frustrating! But the OP has a JD 54" snow blower which requires a grade 5, 1/4" bolt for a shear pin.
