SCBHWJ 42" Replacement Mower Blades 2-Pack for 42-inch Decks — 6-Point Star, 0.138" Thick

These SCBHWJ 42-inch replacement mower blades are a 2-pack of heavy-duty, six-point star center blades designed to fit many Cub Cadet, Troy-Bilt, Craftsman and compatible riding mowers and zero-turns.

If your mower deck is leaving uneven cuts, ragged clippings, or after a season the blades look worn, replacing the blades is the quickest way to restore cutting performance. Each blade in this SCBHWJ set measures 21-1/7" long, 2-3/8" wide and 0.138" thick, and uses a 6-point star center hole to match OEM mounting patterns for many popular models. This listing is for two blades sold together to refresh both cutting sides of a 42" deck or to have a spare on hand.

Which mower models will these blades fit?

These blades are made to be compatible with a broad range of riding tractors and zero-turn mowers that use a 42-inch deck and the six-point star center. They replace several OEM part numbers, giving flexibility when matching parts to older or mixed-brand machines.

• Also fits several Craftsman and Huskee 42" riding mower decks and like-for-like machines.

How do these blades improve mowing performance?

New blades restore a clean bite and even airflow beneath the deck, improving the cut quality and helping grass clippings discharge or mulch consistently. The listed thickness and edge profile are engineered to balance strength and sharpening longevity for regular lawn use.

• Sharp straight-edge profile for neater, more uniform cuts.
• 0.138" thickness for resistance to bending and longer edge life.
• Balanced design minimizes vibration and protects spindle bearings.
• Sold as a pair to renew both sides of a typical 42" deck or keep one as a replacement.

What are the exact specifications I need to check before buying?

Confirm your mower’s blade length, mounting hole pattern and deck width before ordering to ensure fit. Measure the old blade or check your owner’s manual for part numbers to verify compatibility with the six-point star center and the 21-1/7" length.

• Blade length: 21-1/7 inches (fits 42" decks when used in pairs).
• Blade width: 2-3/8 inches; thickness: 0.138 inches.
• Center mounting: six-point star hole matching many OEM hubs.
• Check replacement numbers: includes common OEM part listings for cross-reference.
