How do these toothed blades affect mulching and bagging?

The tooth profile on these blades is designed to increase cutting aggression and lift, which helps break clippings into finer particles for mulching while maintaining sufficient airflow for bagging when required. They balance shred quality with deck airflow to suit mixed mowing tasks.

• Toothed edge promotes finer clippings for improved mulch distribution.
• Raised cutting width and blade lift support consistent bagging performance.
• Balanced geometry helps reduce clogging in damp grass conditions.

What are the exact blade dimensions and mounting details?

Knowing the precise measurements prevents misfits and ensures safe installation. These blades match common 54" deck dimensions and bolt-hole sizing used by many OEM and aftermarket suppliers.

• Overall length: 18 5/8" (approx. 472 mm).
• Center hole diameter: 3/4" (0.75").
• Blade thickness: 0.197" and cutting width: 2 1/2".

What materials and durability should I expect from 8TEN blades?

These replacement blades are produced to provide wear resistance and maintain edge life under normal lawncare conditions. They are suitable for routine mowing, mulching and moderate debris exposure but should be inspected for damage after striking solid objects.

• Engineered for consistent edge retention across multiple uses.
• Manufactured to match OEM mounting and thickness tolerances.
