Keycci Lawn Mower Blade Replacement Compatible with 20" Corded Mowers 25022 25222 25112, Heavy Duty Blade Replaces 29423 29172

What It Is

This is a heavy-duty replacement blade for 20-inch corded electric lawn mowers, specifically designed to fit popular models like the 25022, 25222, and 25112. It replaces OEM part numbers 29423 and 29172, making it a direct swap for worn or dull blades on select mowers.

Fitment & Compatibility

Before buying, confirm your mower has a 20-inch cutting deck—this blade won’t fit smaller or larger decks. Check your mower’s model number against the listed compatible models (25022, 25222, 25112) or OEM part references (29423, 29172). Measure the blade’s center hole diameter (usually 1 inch on these models) and overall length (20 inches). Verify the blade mounting pattern (single hole with a star or keyed shape) matches your mower’s spindle. This is an aftermarket replacement, not OEM, so it may differ slightly in thickness or balance.

Key Things to Know

• Installation is straightforward if you have a socket wrench and a block of wood to lock the blade. No special tools required, but always disconnect the spark plug or power cord first.
• Balance can vary—aftermarket blades may need manual balancing to prevent vibration. Check with a blade balancer or a nail in the wall; file the heavy side if needed.
• Not for gas mowers or other deck sizes—this blade is specific to 20-inch corded electric models. Using it on a different size risks poor cutting or damage.
• Durability is decent for the price, but expect slightly faster wear than OEM blades if you mow thick or wet grass regularly.

Should You Buy It

If you own a compatible 20-inch corded mower and want an affordable replacement that gets the job done, this blade is a solid choice. It’s not premium, but for $20 and easy installation, it beats paying double for OEM if you’re on a budget. Skip it if you need exact OEM fit or mow heavy-duty lawns frequently.
