How to Choose the Right Mower Blade
Blade Types
Standard / Lift Blades: The most common type — creates airflow to lift grass for an even cut and discharge clippings out the side chute.
Mulching Blades: Extra cutting surfaces and a curved shape chop clippings into fine pieces that decompose quickly, returning nutrients to your lawn.
High-Lift Blades: Deeper wing angle generates maximum airflow for bagging applications and tall, thick grass.
Measuring for Fit
Length: Measure the full blade from tip to tip. Arnold blades are available from 18" to 54" to match common deck sizes.
Center Hole: Match the center mounting hole shape — star, round, or universal — to your mower's spindle.
Width & Thickness: Wider, thicker blades handle heavy-duty mowing. Match the original blade dimensions for proper balance and performance.
