Hi all, im trying to figure out the shear bolts for this blower, no plate on it. The shaft has a bolt hole at the blower end but also a 1/4 inch keyway. Any help would be great..thank you

The shear bolt appears to be on the PTO shaft it self close to where it hooks to the PTO on the tractor it is the bolt that look pretty new
 

rrlund any idea what make this might be? It will be on the back of a 2021 b2301 kubota and a first use for me this winter.
 
Take the bolt out, and pull it apart, if its a square tube, its not the shear bolt, it's a round tube in there, it is the shear bolt, a little weak for a shear bolt!
 
Your main shear bolt for the blower is on the pto shaft, the shiny one circled. If it ever breaks you likely busted something else, just too much speed and spin. I think the
bolt protects your tractor, not the blower.....

The shear bolt for the cross auger is the little bolt circled in the other pic. I find this one busts more often.

I use regular #2 bolts when I dont know what the manufacturer asks for. They tend to shear off. Harder bolts may crack off, or,may hold too well and something else
breaks..... its good to find a bolt that fills the hole with solid shaft, not have threads into the shear area.

Your tractor B2301 has 22 horsepower, 17.5 at the pto. It will be fortunate if it will even turn over the
blower, and no way to blow snow. In addition the blower looks awfully heavy. Your tractor may not even lift
it off the ground.
 
(quoted from post at 04:34:26 10/08/21) Lifts and runs no problem, blowing snow in ontario we will see i suppose

Hey man... if nothing else, you will have a killer counterweight for the loader. Put on some chains, and you will be darn near unstoppable...

Just listen to your tractor and watch your temperature gauge. You can always sell the blower, if it works the tractor too hard. That's much easier than replacing your nice Kubota tractor.
 
Snow blowers are an odd thing to size to a tractor. Depends on if the snow is fluffy or wet, packed or loose, etc.

Biggest deal is to have live/ independent pto and have several reverse speeds, really slow is needed at times.

I got a 7 foot snow blower similar to yours. Different manufacturer but it looks to have the same pto shaft brand, gear
case, and very similar design in general.

I was breaking the little shear pin and bending stuff with my 85 hp tractor on it. I only had 2 reverse speeds.

I now use my 27 hp tractor with 3 reverse speeds, and it works better, real nice. But I do need to stop and let it clear
out in difficult deep snow, not enough capacity or power. But when I had enough power I couldnt go as slow and
broke stuff. Now I stall out. I learn when to stop moving and let it clear.

My blower appears to be rated for 40-60 hp.

It works better with the slower 27 hp than it did with the faster 85 hp.

Your tractor sounds quite small, but if you have slow enough reverse gears or hydro, it will sure beat a shovel! :)

Thanks for your reply. Yes its hydro trans and 3 speed, slow and easy will be the game. My furst winter with this tractor, it is fun and will be interesting to see how it performs.
 
Thank you everyone for the advice and
replys. Blower is all ready to go, backhoe
is off the kabota and now we wait. Cheers
all
 
Did you check the oil level in the gearbox? Is that oil you can see in your pictures?

You will be fine with the hydro. Set the RPMS wide open and blow snow.
