ILONPA 42-inch 5-Star Mulching Toothed Blades Blue — 3-in-1 Mulch/Bag/Side-Discharge for Craftsman Husqvarna

These ILONPA 42-inch five-star mulching toothed blades are a direct-fit replacement set engineered to restore cut quality and mulching performance for Craftsman, Husqvarna, Poulan and compatible 42" deck riding and zero-turn mowers.

If your mower’s original blades are nicked, bent, or no longer creating the fine clippings that feed your lawn, this ILONPA replacement pack matches the 5-point star center, dimensions, and mulching profile of OEM part numbers like 138971, 532138971 and 127843. Built as 3-in-1 toothed blades, they are designed to provide bagging, side-discharge, and improved mulching while maintaining the correct lift and fit for many popular 42" decks. The cutting edges ship with protective paint to prevent rust and protect the installer; that coating wears off in normal use.

Will these blades fit my Craftsman or Husqvarna 42" deck?

Yes — the ILONPA set was made to be directly compatible with many Craftsman, Husqvarna, Poulan and other brand models using the 5-point star center. Confirming deck size and center hole specification ensures a correct match and safe operation.

• Compatible with OEM numbers such as 138971, 532138971, 127843 and equivalents.
• Fits 42" decks with a 5-point star center and 5/8" (16mm) center hole.
• Common fits include Craftsman LT1000/LT2000 series and Husqvarna YTH/YT model lines.

How do these toothed, 3-in-1 blades affect cut and mulching performance?

The toothed profile helps lift and circulate clippings, improving mulching action while still allowing effective side discharge or bagging when needed. The 3-in-1 geometry balances airflow, cut quality and reduced clumping under typical lawn conditions.

• Toothed edges create finer clippings for quicker decomposition into the turf.
• Designed air lift (approx. 1" / 24mm) to ensure proper grass flow and consistent cut height.
• Works for bagging, side-discharge, and mulching setups without changing blades.

What are the exact dimensions and mounting specifications?

Accurate measurements matter for fitment and safety; these ILONPA blades match the common OEM geometry used by many manufacturers for 42" decks. Ensure your mower’s spindle and mounting hardware match the listed specs before installing.

• Overall blade length: 20-7/8" (530 mm); width: 2-1/2" (63.5 mm); thickness: ~1/5" (5 mm).
• Center hole: 5-point star type with 5/8" (16 mm) center hole diameter.
• Air lift: approximately 1" (24 mm); designed for 42" compatible decks.

Are there installation or safety notes I should know?

The blades ship with a protective paint coating on the cutting edge to prevent rust and reduce installer injury risk; this coating will wear off during normal cutting. Use proper mounting hardware, torque to mower manufacturer specifications, and always disconnect the spark plug before blade work.

• Cutting edges are painted for protection; the paint will wear off quickly in use.
• Replace blades in matched sets and torque spindle fasteners per manufacturer guidelines.
• Inspect for balance and remove burrs or paint splatters only with appropriate safety gear.

Who is this for: This ILONPA 42" 5-star mulching toothed blade set is ideal for lawnowners and maintenance pros who own Craftsman, Husqvarna, Poulan or other tractors and zero-turn mowers that use the 5-point star 42" deck standard. It's a practical choice if you want OEM-alike dimensions, consistent mulching performance, and a direct-fit replacement that supports bagging and side-discharge options without modifying the deck.
