I am running an IH 80 (?) double auger snowblower on the back of my AC190XT. On the blower, shear-pin, does anyone know what would be a good bolt/grade to run? I threw in 2 bolts/nuts that just fit and busted both off. I was using grade-3 bolts but don't have anymore that fit, time for hardware store run. Do I dare run grade 5 or would I be twisting the shaft? This darn snow is layered, snow, ice, snow, ice, snow and is fun to blow. NOT... Snow's only 16-20 inches deep depending on the area. Sheltered area deeper of course. At half or little more throttle, low side, I was constantly stopping to let clear, seems like low reverse was too fast for the load.

Are the shear bolt holes wollered out? I'd run grade fives, put washers on both sides, and double nut them so they don't come loose. And you are most definitely going to have to be feathering the PD clutch in much snow at all. It won't eat it at full speed. And get your engine RPMs up to almost full throttle. You won't hurt that snow blower, faster is better when it comes to that
I can't say that I would do this, but I know of guys who run a 540 blower on a 1000 shaft. Probably not doing that full speed, but the snow flies

Use grade 5 bolts, and run at full throttle. At half throttle, the blower has no inertia to move the snow. We used to have a Lundell snow thrower, grade 5 bolts, full throttle on a 7060. Would have to feather the clutch on the first pass, but after that would take whatever width would allow for not using the clutch.

No, the shear bolt holes aren't wollered out. Kinda surprising as old/beat up this blower is. I'll look for grade 5 when I hit the hardware store, thanks. I was working the PD pretty hard in the deeper/harder stuff. Straight snow without the darn layer of ice, it throws good.

I have never heard of a Grade 3 bolt.
If you are referring to the three - on the head, that is a Grade 5.
No - is a Grade 2. Five - is a Grade 8, very hard and strong.

I would use grade 5 and don't tighten down against shaft. Use a lock nut to retain bolt. Full throttle puts less torque on shear bolt. MACK

As said,fast pto is better and if you can manage a first pass by slipping along then you can just shave off slices it can handle without slipping PD.

I haven't tried blowing with it yet. Figured maybe Wednesday I will fire her up again. Today, I have battery problems... it's always something. My Ford, Ram, and Buick have dead batteries. I even keep battery tenders on them. The Buick sits in a heated garage so that one came as a surprise but the 2 trucks.... kinda figured they'd be DOA as we're having -20f temps last few days.
Gotta love these January/February temps... oh wait... it's only December.... grrr... LOL

Your location is the biggest obstacle.

Have you tried finding an owners manual for your blower to see what IH recommends?
