Will these blades fit my mower model?

How do these blades improve mulching and cut appearance?

The blade geometry and cutting edge profile are optimized to lift grass, circulate clippings under the deck and re-cut them into finer pieces. That finer mulch decomposes faster and blends into the lawn instead of leaving long clippings on the surface, producing a neater finish after mowing.

• Long 21" length promotes consistent clipping flow along the deck.
• Mulching edge design reduces large clump formation.
• Balanced shape minimizes vibration for a smoother cut.
• Two-blade kit restores deck performance on both sides of the spindle layout.

How do I install and maintain these blades?

Installation follows the mower manufacturer’s standard blade-change steps: disconnect spark plug, tip mower to access blades, remove old blades, and fasten the DOCAS blades securely. Regular maintenance—sharpening when dull, balancing after reshaping and checking fasteners—keeps performance consistent.

• Always disconnect spark plug before working on blades for safety.
• Tighten blade bolts to the torque specified by your mower manual.
• Sharpen with a consistent edge angle to maintain balance and cut quality.
• Inspect for nicks or bends; replace if blades are damaged.
