Stens Notched Hi-Lift Blade

These blades are designed for 42-inch mower decks and feature a 5-point star center hole. They are compatible with several brands, including Ariens, AYP, Craftsman, Husqvarna, McCulloch, Poulan, Snapper, and Viking, but you should always verify your current blade's center hole pattern and length against the 21-inch specification before purchasing.

The hi-lift design creates stronger airflow under the deck, which helps stand the grass blades upright for a more uniform cut. The notched edges then help chop and discharge clippings more effectively, which is particularly useful if you struggle with clumping or have thicker grass.

While these blades are optimized for discharge, they can be used for mulching, though they may not provide the same fine-chopping results as a dedicated mulching blade. If your primary goal is to mulch, you might find that these leave slightly larger clippings than a blade specifically engineered for that purpose.

The 6-pack is designed for maintenance professionals or homeowners with large properties who need to keep spare blades on hand. It allows you to rotate blades out for sharpening without downtime, ensuring you always have a fresh, sharp set ready to go.

No, compatibility is determined by the center hole shape and the specific mounting system of your mower, not just the deck size. Even if you have a 42-inch deck, you must ensure your mower requires a 5-point star center hole pattern for these to fit correctly.
