This pack includes three blades sized for 48″ deck mowers, each with a width of 2-1/2″ and a length of 16-1/4″. The notched high-lift design is intended to improve airflow and cutting performance in yard conditions requiring more lift at the blade edge. Best for budget buyers or households that prefer multiple blades in one purchase for a 48″ deck. Limitation: length is shorter than many OEM blades, so verify deck clearance and compatibility with your mower’s underside design.

Caution: ensure notched design matches your mower’s blade retainer and spacer configuration.

They are positioned as reliable replacements for various 48″ mower decks, with the claim of being genuine OEM Oregon blades.

Caution: confirm the exact mower model and deck compatibility before selecting this pack to avoid mismatches.
Sharp Pebble Cordless Lawn Mower Blade Sharpener
This is a sharpening tool, not a replacement blade. It enables sharpening on most standard residential mower blades, often without removing the blade from the mower. Best for: cordless mower owners who want an at-home sharpening solution and cost-conscious maintenance. A potential limitation is that some blades may require removal for sharpening, which this device handles quickly but not universally.

Caution: confirm center hole and length compatibility with your specific Bad Boy model to avoid mounting issues.
Buying Guide: Key Purchase Considerations
