Why does the PTO shaft shear bolt keep shearing on my Woods Snow Blower?
- PplaneAug 10, 2025
If the PTO shaft shear bolt on your Woods Snow Blower keeps shearing, there are several potential causes. First, ensure that the PTO shaft angle does not exceed 15 degrees. Second, the shear bolt might be too soft; replace it with a grade 5 shear bolt (GKN), a grade 10.9 bolt (Comer 20 series), or a grade 8.8 bolt (Comer 40 series). Finally, excessive tilt on the snowblower can cause this issue; reduce the tilt by adjusting the upper 3-point link.
