Stens 335-331 Snapper 7019523BZYP Hi-Lift Blade,Black

What It Is

The Stens 335-331 is a high-lift replacement blade designed for Snapper walk-behind mowers, optimized for superior grass bagging and discharge performance in thick or tall grass.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is 21 inches—this blade fits Snapper 21" steel decks only. Check your model number against Snapper OEM part 7019523BZYP; this Stens version is a direct aftermarket replacement. Measure your existing blade’s length (21 inches from tip to tip), center hole diameter (typically 1 inch), and thickness (0.187 inch) to ensure exact fit. Not compatible with Snapper 19" or 33" decks, or other brands without cross-reference verification.

Key Things to Know

• Lift & bagging: High-lift design increases suction, so it bags clippings better than standard blades, but it also creates more drag—you may need a more powerful engine (5+ HP) for optimal performance.
• Installation: Requires a torque wrench; tighten center bolt to 50–60 ft-lbs. Use a blade removal tool to prevent spinning. Sharpening is possible but shortens the blade’s life—replace when bent or nicked.
• Common gotcha: High-lift blades can cause “scalping” on uneven terrain if the mower deck isn’t level. Also, they may throw debris farther—always wear eye protection.
• Material: Heat-treated, coated black steel resists rust and wear, but avoid hitting rocks or roots to prevent cracking.

Should You Buy It

If you have a Snapper 21" walk-behind mower and prioritize heavy bagging or leaf mulching, this Stens blade is a solid, affordable upgrade over OEM. It’s not ideal for flat, manicured lawns where a standard blade would suffice, but for thick grass or fall cleanup, it’s a reliable, well-reviewed choice.
