GICOOL Mulching Blades for 38" Deck Mowers — 2-Pack 21" High-Lift Mulch Blades, 6-Point Star Fit

If your mower’s edge has dulled or you want better clippings management, these GICOOL blades are made to match the star-shaped center hub and deck sizes used on many 38" MTD/Troy-Bilt machines. Each blade in the pack is a mulching-style, high-lift design intended to finely chop grass while maintaining airflow for bagging. The set replaces several OEM numbers and fits a wide list of models, but always double-check your mower’s part number before ordering to ensure compatibility.

Which mower models and OEM numbers do these blades fit?

• Verify the 6-point star center hole and 21" blade length on your existing blade before purchasing.

How do these blades improve mowing performance?

The blades combine a multi-curve cutting surface and a high-lift wing to manage clippings more effectively. That mix helps produce finer mulch for return to the lawn and improves bag pickup when collection is desired.

• Multi-curve edge chops clippings into smaller pieces for easier breakdown.
• High-lift wing increases airflow to lift grass for cleaner cuts and better bagging.
• Balanced design reduces vibration for smoother operation and extended spindle life.
• Rust-resistant edge coating protects during handling and wears off during use.

What are the construction and sizing specifics?

GICOOL blades are stamped and heat-treated from durable steel to meet the demands of routine lawn maintenance. The center hole uses a 6-point star profile to align precisely with compatible mower spindles.

• Blade length: 21 inches (per product specifications).
• Center hole shape: 6-point star to match specified mower hubs.
• Blade type: Mulching blade optimized for mulching, bagging, and side discharge modes.
• Sold as a pack of 2 replacement blades to service both sides or keep a spare.

How do I choose and install the right replacement blade?

Choosing the correct blade requires matching the length, center hole shape, and deck compatibility. Installation typically uses the original hardware and basic hand tools; follow your mower manual for torque specs and safety steps.

• Confirm your mower’s OEM blade number or compare the existing blade’s center hole and length.
• Disconnect spark plug and secure the mower before blade removal or installation.
• Use the original mounting bolt and tighten to manufacturer torque recommendations.
• Replace blades in matched pairs when possible to maintain balance across the deck.

It’s suitable for users seeking improved mulch quality and better bagging performance without changing their mower’s deck or hardware.
