Caltric 30" Deck Mulching Blade Compatible with Cub Cadet 13A726JD056 13A221JD010 13A721JD010 CC30 13A726JD010 13AC21JDA10 13B221JD010 13C721JD010 942-04385

What It Is

This is a 30-inch mulching blade set from Caltric, designed to replace the OEM blade on specific Cub Cadet lawn tractors and zero-turn mowers. It is intended for cutting grass and finely chopping clippings to return nutrients to the lawn, reducing the need for bagging.

Fitment & Compatibility

Before buying, confirm your mower deck size is exactly 30 inches. This blade is listed as compatible with Cub Cadet models including 13A726JD056, 13A221JD010, 13A721JD010, CC30, 13A726JD010, 13AC21JDA10, 13B221JD010, and 13C721JD010. It also replaces OEM part number 942-04385. Measure your existing blade length, center hole diameter (typically 1-inch), and spindle hole pattern to ensure a match. This is an aftermarket part, not OEM Cub Cadet, so check that your mower uses a standard 3-point or oval center hole—some newer models may require a specific OEM shape.

Key Things to Know

• Quality: Caltric blades are generally well-regarded for the price, but the single 5-star review means long-term durability is unproven. Expect decent steel but possibly less edge retention than OEM.
• Installation: Simple bolt-on replacement if your deck uses standard blade bolts. Use a torque wrench to tighten to 50-70 ft-lbs (check your mower manual). Always disconnect the spark plug and lift the deck safely.
• Common gotchas: Mulching blades have a higher lift and more curved surface than standard blades, which can stress the engine if the grass is thick or wet. Also, ensure your mower deck has a mulching plug or kit installed for best results—without it, clippings may not circulate properly.
• OEM vs aftermarket: If you have a warranty or prefer exact fit, stick with Cub Cadet OEM. This Caltric blade is a cost-effective alternative but may not match the original blade’s balance or coating.

Should You Buy It

Buy this if you own one of the listed Cub Cadet models with a 30-inch deck, want a mulching blade for finer clippings, and are comfortable with aftermarket parts. It’s a good value at $46 if you don’t need OEM-specific features, but if you prioritize guaranteed performance or have a warranty, stick with the Cub Cadet branded blade.
