IDEASURE mulching mower blades for 38" deck — 2-pack, heavy-duty steel, fits Cub Cadet 1515/1525/2130 series

IDEASURE 759-3829 mulching blades are a two-pack of heavy-duty replacement blades designed to convert or restore a 38" mower deck for efficient mulching and even cutting.

These replacement blades fit a range of Cub Cadet and related models and are built from one solid piece of thick steel for extended life and dependable cutting performance. They come as a matched pair with precise dimensions so you can verify compatibility before purchase. Whether you need to refresh worn blades or upgrade to mulching-style edges, these blades are sized and drilled to match common OEM part numbers.

Will these blades fit my Cub Cadet 38" mower deck?

Confirming fit is simple: compare the blade dimensions and the center hole with your mower’s original part. The package contains two blades sized to suit most 38" decks used on the listed Cub Cadet models, and they replace several OEM numbers.

• Length: 19-5/16" (fits 38" decks)
• Width: 2-11/16"; Thickness: 0.197"
• Center hole diameter: 3/4" (verify against your spindle)
• Replaces: 759-3829, 742-0321, 742-0322, 742-3032, 742P3032, and others

How do these blades affect cutting and mulching quality?

The blades are shaped and sharpened to promote fine clippings and consistent discharge patterns, improving grass clippings circulation under the deck for better mulching. Their thick-steel construction keeps the cutting edge straighter longer, delivering a more even finish across different grass types.

• Mulching profile helps reduce clump formation
• Uniform cutting edge for consistent grass height
• Durable one-piece steel resists warping and bending
• Optimized for a 38" deck’s airflow and lift

What installation and maintenance should I expect?

Installation follows the same steps as swapping any mower blade: park on a flat surface, disconnect spark plug, remove old blades, and torque the new blades to the manufacturer’s specification. Routine sharpening and inspection will extend their life; bend or severe damage means it’s time to replace rather than resurface.

• Always disconnect spark plug before working on deck
• Use correct spindle bolt and torque settings for your mower
• Inspect for nicks and balance after sharpening
• Replace in pairs to maintain deck balance and performance

Which OEM numbers and mower models are these compatible with?

These IDEASURE blades are designed as direct replacements for multiple OEM part numbers and fit several Cub Cadet models commonly equipped with 38" decks. Cross-check the listed part numbers and model series against your mower documentation to ensure proper match.

• Replaces part numbers including 759-3829, 742-0321, 742-0322, 742-3032, 742P3032
• Also replaces 942-0473A, 91-057, 325-742 among compatible lists

Choose this two-pack if you want a reliable, heavy-gauge steel replacement set for routine maintenance, seasonal blade swaps, or converting a deck to improved mulching performance.
