Perfect fit for Craftsman 42 inch mower blades, 42 inch mulching blades, 42 inch high lift blades & 42 inch riding mower decks—matches original specs for seamless compatibility with 42 inch lawn tractors and zero turns.
✓Stop Guessing—Match the Right Blade Mounting Pattern First: Craftsman 42" deck riding lawn mowers (including LT1000, LT2000, and more) feature two distinct blade mounting patterns. To ensure a perfect fit for your mower, please confirm your original blade’s mounting design before placing an order. Our replacement blades are engineered with a 5-point star hole mounting pattern. For mowers requiring a 6-point star hole design, order blades using MPN 942-0616A or 942-04308.
✓Precise Blade Specifications: Blade Length: 20-7/8" (diagonal tip-to-tip), Width: 2-1/4", Thickness: 0.17". Features 5-point star center hole, 1" air lift, 3.1" cutting edge. High-lift design creates strong airflow for efficient bagging and side discharging.
✓Includes Hardware Kit for Easy Installation: Comes with 2 full sets of premium hardware (part# 532193003) – 7/16"-20 x 1-1/4" bolts and washers. Installs in minutes with basic tools. 2-in-1 functionality works for both bagging and side discharging, reducing clogging risk.
✓2-in-1 High-Lift Mulching Blades for Effortless, Clog-Free Lawn Care: Dual-function design handles bagging, side discharging, and mulching—perfect for tall/wet grass or any grass type. Generates powerful suction and airflow to deliver smooth, even cuts, stop grass clippings from piling up (no more clogging headaches), and chop clippings finely to feed your lawn naturally for a lusher, healthier yard.
✓Heavy-Duty High-Carbon Steel Blades: Durable, Safe & Ready in 5 Minutes. Crafted from premium high-carbon steel for long-lasting sharpness and bend resistance, built for tough mowing jobs. Protective powder coating prevents rust in storage and shields hands during installation—no paint scraping needed; it wears off naturally to reveal pre-sharpened edges. Simply align cutting edges, secure the blade, and go! Rigorously tested (Rockwell Hardness, Balance, Field Test & more) for total reliability.
