Stens 335-240 Snapper 7019795BZYP Hi-Lift Blade,Black

What It Is

The Stens 335-240 is an aftermarket hi-lift mower blade designed for Snapper walk-behind mowers and some other brands, engineered to create strong upward airflow for improved bagging and discharge of grass clippings in high-volume cutting conditions.

Fitment & Compatibility

Before buying, confirm three things: deck size (this is a 21-inch blade), OEM part number (cross-references to Snapper 7019795BZYP, 7019795BY, and others), and center hole shape (it uses a 5-point star center hole, common on Snapper decks). Measure your current blade’s length from tip to tip (must be exactly 21 inches) and check the center hole shape—if you have a round hole or different star pattern, this won’t fit. Also verify your mower’s deck type (side-discharge or bagging) – hi-lift blades work best on baggers but can strain side-discharge decks at low rpm.

Key Things to Know

• Lift & bagging performance: Hi-lift design significantly improves clipping lift into the bag, but creates more drag – expect slightly slower engine speed and more power draw than standard blades.
• Installation tip: Use a blade removal tool or wedge to lock the blade; torque to 35-45 ft-lbs. The star center hole must align perfectly – forcing it can damage the adapter.
• Sharpening caution: Hi-lift blades have a steep angle; sharpen only the cutting edge (not the lift wing) to avoid imbalance.
• Durability: Stens blades are heat-treated steel; they hold an edge well but may bend if you hit rocks or roots.

Should You Buy It

Buy this if you own a Snapper 21-inch walk-behind with a bagging system and want maximum grass lift for thick lawns or wet conditions. Skip it if you have a mulching deck or side-discharge only – the extra lift can cause clumping and uneven cut.
