Which Kubota models and part numbers do these blades replace?

These blades are manufactured to match several Kubota OEM numbers and fit multiple 54" deck configurations. They’re intended as direct replacements so you won’t need adapters or re-drilling.

• Compatible OEM part numbers: Kubota 70000-00605, 70000-25004, 76529-34330, K5615-34330.
• Designed for Kubota 54" deck models such as RCK54-18Z, RC54-24B, RC54-71B, RC54-B, RC54-F19, RC54-FZ21, RC54-G20.
• Offered as a 3-pack to replace all three blades on a standard 54" deck at once.

What are the exact blade dimensions and mounting details?

Knowing the blade’s measurements ensures proper clearance, balance and bolt fit. These LawnRAZOR blades list the key dimensions so you can confirm compatibility before purchase.

• Overall cutting length: 18 11/16 inches (measured tip-to-tip).
• Center mounting hole diameter: 1 1/4 inches for standard Kubota spindles.
• Blade width: 2 1/2 inches; material thickness: 0.236 inches for durability and reduced flex.

How will these high-lift blades change mowing performance?

High-lift profiles generate stronger upward airflow under the deck, improving grass lift and more consistent discharge into the chute or bagger. Expect better clipping dispersion and cleaner cuts on dense or damp turf when blades are sharp and balanced.

• Stronger suction helps lift flattened grass for a uniform cut height.
• Enhanced discharge reduces clumping and improves bagging efficiency.
• Durable steel thickness resists bending and preserves cutting edge longer.

What should I know about installation and maintenance?

Installation is straightforward for anyone familiar with mower blade replacement, but safe practices matter. Regular inspection and sharpening keep blades cutting well and reduce strain on the deck and engine.

• Replace blades pairwise or as a full set; this pack includes three for a 54" deck.
• Torque mounting hardware to the manufacturer’s spec and check balance after installation.
• Sharpen or replace blades when the edge is nicked, rolled or uneven to avoid striping or scalping.

Choose this 3-pack when you want a like-for-like replacement that restores deck airflow, improves clippings handling, and saves time by changing all three blades at once.
