Understanding Shear Bolt PTO Shafts
Before diving into the buying process, it’s essential to understand what a shear bolt PTO shaft is. Essentially, it’s a safety feature designed to protect your machinery from damage. When a sudden overload occurs, the shear bolt breaks, preventing further damage to the tractor or implement.

Generally, I noticed that standard models could be found for around $100-$300, while heavy-duty options could range from $300-$600 or more.
