What It Is

This Autoparts-branded part is a universal replacement blade set for walk-behind lawn mowers, designed to deliver a clean cut for residential turf maintenance. It fits most 20- to 22-inch deck mowers with standard center hole and oval mounting patterns.

Fitment & Compatibility

Before buying, measure your existing blade’s length (from tip to tip) and center hole diameter—this set fits 20-22 inch decks with a 1-inch center hole and 5-point star or oval pattern. Check your mower’s brand and model against Autoparts’ compatibility list (available on the product page); common fits include Craftsman, Troy-Bilt, and MTD, but verify your specific model number. This is an aftermarket part, not OEM, so confirm the blade thickness matches your spindle’s clearance—typically 0.1-0.15 inches.

Key Things to Buy

• Quality: Heat-treated steel with a painted coating resists rust, but may dull faster than premium OEM blades on tough grass or debris.
• Installation: Easy for DIYers—requires a socket wrench and torque to manufacturer specs (usually 35-45 ft-lbs). Use a blade removal tool for safety.
• Gotcha: Balanced out of the box, but always check balance with a blade balancer to avoid vibration and spindle wear.
• Note: Not for zero-turn, riding, or electric mowers—walk-behind gas models only.

Should You Buy It

Buy this if you need a budget-friendly, reliable replacement for a standard walk-behind mower and are comfortable with basic DIY installation. Skip it if you have a non-standard deck size, a commercial mower, or prefer OEM parts for maximum longevity.
