The Toro 620 models shear pin are hard to replace. Once you get broken pin out you need to tape in the new bolt so when you turn the rotor to opposite side to but on nut with long nose pliers the bolts won\'t fall out. Long extended sockets needed on both nut and bolt end
Good luck

Snow blower has 2 separate augers attached to the auger shaft by a bolt and locking nut. I used a small piece of electrical tape to hold the bolt in place while I attached the nut from the opposite side of the shaft. Then I used two ratchets to hold one side while tightening other side, donGÇÖt forget to wear gloves.

1.tipped the blower back until handles were on the ground.
2. Rotated the auger shaft by rotating the impeller until the bolt hole in shaft was in a workable position, then pushed out piece of the broken bolt that was in the shaft.
3. Inserted the new bolt from bottom side and started the nut. This is the awkward part because the bolt is within the auger hub. Snugged down the self locking nut.
4. Returned the blower to its normal position. Started engine and tested the auger for proper action. DONE.
5. IMPORTANT: Ordered 2 new bolts and locking nuts from ereplacementparts to have on hand if another bolt shears.
