How does the blade type affect cutting and mulching?

These are high-lift mulching blades: the raised lip draws grass upward beneath the deck, then recirculates and chops clippings into finer pieces. Finer clippings decompose faster and can improve the appearance of the lawn when used correctly.

• High‑lift design improves grass lift for a cleaner cut.
• Mulching edge profile reduces clipping size for quicker breakdown.
• Balanced shape minimizes vibration and protects spindle bearings.
• Durable 1/8" thickness resists bending under normal use.

What are the physical dimensions and mounting details?

Each blade is specified to match typical OEM dimensions so it mounts easily without modification. The bow-tie center hole fits the mounting hardware used on many 21" decks, and the thickness and width align with original equipment tolerances.

• Overall length: 21 inches.
• Width: 2 1/9 inches; Thickness: 1/8 inch.
• Center hole: bow-tie shape for direct OEM replacement.
• Sold as a 2-pack for replacing both blades on dual-blade decks or keeping one spare.

How should I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect spark plug, remove mounting bolt(s), swap blades ensuring correct orientation, and torque bolts to manufacturer specs. Routine maintenance extends blade life and maintains cut quality.

• Disconnect spark plug before starting work for safety.
• Sharpen blades periodically for optimal cutting performance.
• Inspect for nicks or bends and replace if damaged.
• Follow your mower manual for correct torque and blade direction.
