Hi all, I have a cub cadet 3 stage snow blower. we just had a 30+ inch snowstorm here in the northeast. anyway, before i started blowing i noticed the shear pin on the rear accelerator blade(right behind the gearbox) was broken...No problem because i had some that came with the blower. at this point the blade was totally free and spinning on the shaft. So after blowing for a few hours i picked up a rock which jammed between the same blade and the housing and sheared the pin again. only THIS time i can see the remains of the old pin still in the shaft BUT the hole in the blade is offset a bit so I cant punch the old one out. The blade will not move on the shaft no matter what i try. It seems almost like a piece of the old pin is possibly jammed between the bade and the shaft??? I took off the front blade for better access but no luck. Don't want to start hammering on it for fear of damagung anything. any thoughts???
