TENGMUJX lawn mower blades for Kubota 54" deck — 3-pack high-lift OEM-fit K5613-34340, durable steel

TENGMUJX K5613-34340 high-lift lawn mower blades are direct-fit replacement blades for 54" Kubota decks, sold as a convenient 3-pack to restore cutting performance and lift for clean bagging and discharge.

When your Kubota zero-turn or lawn tractor isn’t producing the clean cut or bagging suction it used to, worn blades are often the cause. These TENGMUJX blades are manufactured to match Kubota OEM K5613-34340 specifications, so they fit 54-inch decks such as RCK54P-400Z (Z421KW-3, Z422KW) and RCK54P-781Z (Z724XKW-3). Built from durable steel with precise dimensions, they offer a cost-effective way to refresh your mower without buying a new deck.

How do these blades improve cut quality and bagging performance?

High-lift geometry creates stronger airflow under the deck so clippings are lifted and suspended for a cleaner, more even cut and improved mulching or bagging. Replacing worn or nicked blades restores the original blade profile and efficient airflow characteristics.

• High-lift design increases suction for bagging and collection
• Sharp factory edges promote even cutting and reduced tearing
• Consistent thickness and profile maintain deck airflow balance

Will these fit my Kubota 54" deck and replace OEM part K5613-34340?

Yes — these blades are manufactured to match the OEM dimensions and mounting pattern for K5613-34340 replacements. They are compatible with several 54-inch Kubota decks commonly used on walk-behind and zero-turn models.

• Compatible with RCK54P-400Z (Z421KW-3, Z422KW) decks

How easy is installation and what tools are required?

Installing these blades is a straightforward DIY task for anyone comfortable with basic mower maintenance. You’ll need common hand tools and a safe method to support the deck or spindles while swapping blades.

• Basic tools: wrench or socket set to remove blade bolts
• Recommended: blade holder or strap to prevent rotation during removal
• Torque bolts to manufacturer specs and check balance after installation

What materials and quality controls ensure durability?

TENGMUJX manufactures these replacement blades from heavy-gauge steel and applies finishing processes to resist wear and deliver consistent edge life. Quality checks during production aim to keep dimensions uniform so the blades balance properly and perform reliably.

• Durable steel construction with consistent thickness (1/4")
