I have no idea how this happened but I'vet managed to bend the auger on my 59" front mounted snowblower (mounted on Deere 3720). Apparently the left auger tip near the side of the blower is hitting the skid shoe. Naturally I broke a shear pin but didn't realize why until I broke a second shear pin and began investigating. The bend in the auger tip isn't very apparent to the eye and the auger rotates freely with the shear pin out. Once a shear pin is installed, it will tighten up enough to cause the tip to hit the shoe if there's a enough lateral force. Oddly, it worked fine for about about an hour before breaking the 2nd shear pin this afternoon.
Any suggestions on how to bend the auger back to normal? My typical hillbilly approach would include a MAPP torch and beat it into submission with a 4lb hammer but there's not enough room to take a good swing at it. My other thought is to flip the skid shoes to the outside of the blower bucket and call it a day.
