What It Is

The Proven Part (model unspecified in listing) is a replacement blade for walk-behind lawn mowers, designed for cutting grass on residential lawns. It fits standard 21-inch mower decks.

Fitment & Compatibility

Before buying, measure your existing blade’s length, center hole diameter, and mounting pattern. This part is aftermarket, so it may not match OEM specs for all brands. Check your mower’s model number against Proven’s compatibility list (if available) or verify that the blade’s dimensions match your deck’s requirements. Avoid assuming fitment based on brand alone—measure twice, buy once.

Key Things to Know

• Quality: Single review (5.0/5) suggests good performance, but no long-term durability data. Expect standard steel blade wear.
• Installation: Easy for DIYers—remove spark plug wire, unbolt old blade, replace with new one. Torque bolts to manufacturer specs (usually 30-50 ft-lbs).
• Gotcha: No OEM guarantee. If your deck has a specific blade shape (e.g., mulching, high-lift), verify this part matches. Proven may offer a universal design that underperforms on some decks.
• Price: $82.35 is high for a single aftermarket blade. Compare with OEM options (often $20-$40) before committing.

Should You Buy It

Only buy if you’ve confirmed exact fitment with your mower’s model and deck specs, and you’re okay paying a premium for a part with minimal user feedback. For most, a cheaper OEM or proven aftermarket brand (e.g., Oregon) will be a safer bet.
