Troy-Bilt

What It Is

This is a genuine OEM replacement blade for Troy-Bilt walk-behind mowers, designed to cut grass efficiently. It fits select 21-inch and 22-inch deck models, typically used for residential lawn care.

Fitment & Compatibility

Before buying, confirm your mower’s deck size (measure cutting width, not the housing). Check your model number—commonly fits TB110, TB120, TB130, TB200, and TB230 series, but not all variations. This is a Troy-Bilt OEM part, so it matches factory specs; aftermarket blades may differ in thickness or hole pattern. Measure the blade’s center hole diameter (usually 1-inch or 5/8-inch) and overall length (needs to match your deck’s cutting width). Verify your blade type: this is a standard straight or slightly curved blade, not a mulching or bagging-specific design.

Key Things to Buy

• Quality: OEM build ensures balanced cutting and durability; aftermarket blades may cause vibration or poor cut if not matched.
• Installation difficulty: Easy—requires a socket wrench to remove the center bolt. Use a blade removal tool or block the blade to prevent spinning. Torque the bolt to 30-40 ft-lbs.
• Common gotchas: Ensure the blade is installed with the curved side up (or stamped “this side up”) for proper lift. Re-check bolt tightness after 15 minutes of use. Don’t reuse old washers or bolts; they can wear and fail.
• Warranty: Using OEM parts keeps your mower’s warranty valid; aftermarket may void it.

Should You Buy It

Buy this if you own a compatible Troy-Bilt walk-behind and want a reliable, factory-fit blade for standard grass cutting. It’s ideal for replacing a dull or damaged blade on a mid-range model like the TB110 or TB230. Skip it if you need a mulching blade, a different brand, or a cheaper aftermarket option—but expect potential fit or performance trade-offs.
