Maxpower 331653B Lawn Mower Replacement Parts, Black Review

Maxpower 331653B Lawn Mower Replacement Parts Review

Overview

The Maxpower 331653B is not a lawn mower itself, but a replacement blade kit designed to fit most 21-inch walk-behind mowers with a universal “star” or “D” shape center hole. Priced at just $21.49, it’s aimed at budget-conscious homeowners who want to restore cutting performance without buying a new machine or paying dealer prices for OEM blades.

Who Should Buy This

• Homeowners with aging mowers – If your current blade is dull, chipped, or bent, this kit gives you two sharp, balanced blades for less than the cost of a single OEM replacement from some brands.
• DIY repair folks – If you’re comfortable flipping your mower over and swapping a blade (it takes about 10 minutes), this is a no-brainer value.
• People with standard 21-inch mowers – This fits Craftsman, Troy-Bilt, MTD, Husqvarna, and many others with a 6.5-inch center hole and 3.5-inch arbor. Check your mower’s manual first.
• Budget-first shoppers – If you’re not chasing premium features like mulching or high-lift performance, these get the job done for a fraction of the cost.

Key Features Breakdown

• Blade Length: 21 inches – This is the standard size for most residential push mowers. It covers the full cutting width without overhang, so you won’t get uneven strips or scalping on flat lawns.
• Center Hole: 6.5 inches with star/D-shape – Universal fit for most single-bolt mowers. The star pattern locks the blade to the crankshaft, preventing slippage during operation. If your mower uses a different hole shape (like a 7-point star), double-check compatibility.
• Material: Heat-treated steel – Hardened to resist bending and chipping from rocks or roots. It won’t last as long as high-carbon or stainless blades, but for the price, it’s durable enough for typical weekly cuts on grass under 6 inches.
• Pack Quantity: 2 blades per kit – You get a spare, which is smart. One blade can last a season on a small lawn; having a backup means you’re never stuck with a dull cutter mid-summer.
• Thickness: 0.125 inches – Standard thickness for residential blades. It’s not as beefy as commercial-grade (0.187 inches), but it keeps weight low and reduces strain on smaller mower engines.

Pros

1. Outstanding value – Two blades for $21.49 is about half the cost of many OEM replacements. You save money without sacrificing basic cutting ability.
2. Universal fit on popular brands – Works with Craftsman, Troy-Bilt, MTD, Husqvarna, Yard Machines, and many others. No need to hunt for a specific model number.
3. Easy installation – The star-shaped hole aligns with most mower crankshafts without fuss. Just remove the old blade, bolt on the new one, and torque to spec (usually 40-50 ft-lbs).
4. Sharp out of the box – Edges are cleanly ground and ready to cut. Users report clean cuts on grass up to 4 inches tall with no tearing or browning.
5. Balanced for smooth operation – Minimal vibration after installation, which reduces wear on your mower’s spindle and engine bearings.
6. Spare blade included – Having a second blade means you can sharpen one and swap it in while the other is being used. Extends the life of your kit.

Cons

1. Not for mulching or bagging – These are standard lift blades. They don’t have the curved fins or aggressive airfoil needed for fine mulching or high-performance bagging. Expect clumps if you try to mulch wet or tall grass.
2. Thinner steel than premium blades – At 0.125 inches, they’re more prone to bending if you hit a sprinkler head or large rock. Not ideal for rough terrain or rocky lawns.
3. Inconsistent fit on some mowers – A few users report the center hole doesn’t perfectly align with certain older or less common mower models. Always measure your existing blade’s center hole before ordering.
4. No coating or anti-rust treatment – These are bare steel blades. They’ll rust if left wet or stored in a damp shed. Wipe them dry after use and oil lightly for longevity.

Bottom Line

The Maxpower 331653B is a solid, budget-friendly replacement blade kit for homeowners who want to restore their mower’s cutting performance without spending OEM money. It’s best for small to medium lawns with normal grass conditions and occasional obstacles. If you need high-lift mulching, heavy-duty durability for rocky yards, or a perfect fit for a rare mower model, look elsewhere. But for the vast majority of Craftsman, Troy-Bilt, and MTD owners, this kit delivers sharp cuts, easy installation, and a spare blade for a price that’s hard to beat. Recommended for cost-conscious DIYers who don’t need premium features.

Frequently Asked Questions

Will these blades fit my Honda or Toro mower?
Probably not. Most Honda and Toro mowers use a unique oval or “bowtie” center hole that’s different from the universal star pattern. Always check your mower’s manual or measure the existing blade’s center hole before purchasing.

How often should I replace the blades?
For a typical 1/4-acre lawn cut weekly, replace these blades once per season or after 25-30 hours of use. If you hit rocks or roots, inspect them monthly for nicks or bends.

Can I sharpen these blades?
Yes. They’re standard steel and can be sharpened with a file or bench grinder. Just keep the original angle (about 30 degrees) and re-balance them after sharpening. The spare blade gives you time to sharpen one while using the other.
