2105300125A Lawn Mower Blade Compatible with Hyper Tough Push Mower MNA152505, MNA152701, MNA152516, 20" Lawn Dethatcher Blade Replace 101000001, 355-101

What It Is

This is a 20-inch dethatcher blade designed for Hyper Tough push mowers, specifically to remove thatch and debris from lawns rather than for standard grass cutting. It replaces OEM part numbers 101000001 and 355-101.

Fitment & Compatibility

Before buying, confirm your mower has a 20-inch deck (measure the cutting width). This blade is compatible with Hyper Tough models MNA152505, MNA152701, and MNA152516—check your model number on the mower’s sticker. It’s an aftermarket replacement for the OEM 101000001/355-101, so verify your current blade’s part number if unsure. Measure the blade’s center hole diameter (typically 1 inch) and overall length (20 inches) to match your spindle. Also check the blade thickness (usually 0.125 inches) and sail orientation (curved upward for dethatching).

Key Things to Know

• Dethatcher vs. mulching blade: This is not for regular mowing; it aggressively rakes the lawn surface, so use it in spring or fall.
• Installation difficulty: Moderate—requires a socket wrench and possibly a blade removal tool. Wear gloves; the edges are sharp.
• Common gotcha: Ensure the blade is mounted with the curved side facing up toward the deck, or it won’t function correctly.
• Quality note: With only 2 reviews (5.0 rating), consider checking recent buyer feedback for durability, especially on thicker thatch.

Should You Buy It

Buy this if you own a compatible Hyper Tough 20-inch push mower and need a dedicated dethatcher blade for seasonal lawn renovation. It’s a budget-friendly alternative to OEM parts, but verify your exact model and blade measurements first—especially if your mower is older or has been modified.
