Cub 3x snowblower/ shear pins

[hawg]

I have a cub three stage snowblower that eats shear pins like candy, I went through two dozen of them last year. I checked with cub and they say they have a new shear pin that they sell for the third stage impeller‘s, but they cost six or seven dollars apiece, or in a kit with two of the good ones and four cheapies for $18.99. These sheer pins have a hex head on them like a bolt, but they still have the pin fastener in the bottom. They say A on the head of the pin. Does anybody know what that A stands for, and where to get some? $18.99 for two of them and four cheapies is ridiculous. I do know that it's not a grade 8 like a lot of people think, those are way too hard and will break your shaft.

I got tired of these in my blower I used brass bolts

Do they break at a lower enough pressure as to not take out shafts? I've heard there's not hardly a shaft available in the whole United States from people putting bolts in them. What ticks me off so bad is the cub knows the problem, never fixed it, and wants to screw us on the sheer pins.

Use a grade 2 bolt of the same length and diameter and score it 1/4 way through with a hacksaw about 1/8" to 3/16" down from the head. Make up a bunch while you have the tools out

Or if you have room just lock tight a nut on the bolt or use lock nuts with the plastic insert..

We have a Kubota and the shear pins are $5 each also. Impellar is a grade 8 and augers are a grade 5.

I just bought the kit from my dealer for under $12.00. Home Depot also sells them

Clean up the beer bottles and cans so you stop hitting them

It goes right thru the bottle but those 16 oz cans bind it up every time

I am going to try the Cub ones, cheap enough if they aren't grade 5. I called MTD and they don't even know what grade they are, or if they do they wont say. I found a Cub dealer online by putting the part number in Google. Cub's web page had a 3 pack for $5.99 EACH & $7.99 shipping! Sorry I can't get the picture to turn over, It will on my phone and computer but not on WC????
