Antanker 21" High-Lift Mower Blades for 42" Lawn Tractor — 2-Pack, 5-Point Star Fit

Antanker high-lift replacement lawn tractor blades — two 21" blades engineered to restore cutting performance on 42" mower decks with the 5-point star center mount.

These Antanker 134149 high-lift blades are a direct-fit aftermarket option designed for many popular 42" riding mower decks. Each blade measures 21 inches long with a 2-5/16" cutting width and a 5-point star center hole so they align with common OEM mounting patterns. This two-pack gives you both sides of the deck covered when replacing worn or damaged blades, and the high-lift profile helps move clippings efficiently for bagging or side discharge on compatible tractors.

Which machines will these Antanker blades fit?

These blades are built for 42" decks that use a 5-point star center mount and the 21" length. They are compatible with many models from Husqvarna, Poulan, Craftsman, Snapper and other brands that list the matching OEM numbers.

• Compatible with Poulan and Poulan Pro 42" decks and select PB/PP/PXT models.
• Replaces multiple OEM part numbers across Ariens, AYP, Craftsman, Husqvarna, Poulan and Snapper.

How do these high-lift blades affect mowing performance?

The high-lift shape creates stronger upward airflow beneath the deck, which helps lift grass for a cleaner cut and improves material movement for bagging. They are particularly useful when you want more suction to feed clippings into a collection system or to force a more even discharge.

• High-lift lip design increases suction for better bagging and discharge.
• Sharp, consistent cutting edge reduces tear and promotes uniform clippings.
• Durable steel construction maintains blade shape under regular residential use.

What are the exact specifications and OEM replacements?

Each blade is 21" long and 2-5/16" across the cutting edge, with a 5-point star center hole matching many 42" deck mounting patterns. The package includes two blades to service both spindles on most twin-blade decks.

• Blade length: 21" (approx. 533 mm); cutting width: 2-5/16".
• Center hole: 5-point star mounting pattern for direct compatibility.
• Replaces numerous OEM numbers from Ariens, AYP, Craftsman, Husqvarna, Poulan, Snapper and others.

How do I install and maintain these replacement blades?

Install by securing each blade to the spindle with the factory hardware, observing correct blade orientation and torque specifications from your tractor manual. Routine maintenance includes checking for straightness, nicks, and proper balance; sharpen or replace blades as needed to preserve cut quality.

• Always disconnect spark plug and follow mower safety steps before working under the deck.
• Tighten blade mounting bolts to the torque specified by your tractor manufacturer.
• Inspect blades after hitting obstacles; replace if bent, cracked or excessively worn.
