CMXGZAM110191 42" Ultra High-Lift Bagging Blade Set for Craftsman 42 Inch Riding Mowers and Zero-Turn Mowers, S-Shape Center Hole, Set of 2

What It Is

This is a set of two 42-inch ultra high-lift bagging blades designed for Craftsman 42-inch riding mowers and zero-turn mowers. The aggressive blade shape creates a strong vacuum to lift grass clippings into the bagger, making it ideal for mulching or bagging in tall, thick grass.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch cutting deck and uses blades with an S-shaped center hole (not a star or oval). These blades are OEM replacement for Craftsman models using part numbers CMXGZAM110191, 138193, or 137-193. They fit most Craftsman 42-inch riding mowers (e.g., LT2000, T210, YT3000) and select zero-turn models (e.g., ZT 7000 series). Measure your existing blade length: must be exactly 42 inches total for a 42-inch deck. Check the blade thickness (0.25 inches) and center hole diameter (1 inch) to match your spindle. Not compatible with 46-inch or 54-inch decks.

Key Things to Buy

• Lift vs. cut: High-lift blades increase suction for bagging but can reduce fuel efficiency and create more noise. Not ideal for dry, short grass.
• Installation torque: Tighten blade bolts to 70-90 ft-lbs. Over-tightening can warp blades; under-tightening can cause wobble.
• Sharpening care: These blades have a hardened edge—sharpening with a grinder can overheat and weaken steel. Replace instead of sharpening if heavily worn.
• Deck alignment: After installation, ensure blades spin freely and don’t hit the deck. Check blade tip clearance (should be 1/8 to 1/4 inch from deck edge).

Should You Buy It

Buy these if you own a Craftsman 42-inch riding mower and want reliable OEM-grade bagging performance for thick, wet grass. The high lift design excels at filling bags quickly, but if you primarily mulch or side-discharge on dry lawns, a standard or low-lift blade is a better choice.
