8 Best Briggs & Stratton Lawn Mower Blade Replacements to Buy in 2025

Masterfully engineered for reliability, this Briggs & Stratton blade is the quintessential OEM replacement for restoring your mower’s original performance. As a genuine 1731898BZYP part, it guarantees a perfect fit, eliminating the dangerous vibrations and poor cut quality often associated with ill-fitting aftermarket alternatives. For homeowners frustrated with uneven lawns, this blade provides an immediate and effective solution, ensuring your equipment runs exactly as the manufacturer intended.

In real-world testing on a typical suburban lawn with a mix of fescue and rye grass, the blade delivered a consistently clean and even cut. Its factory-balanced design puts less strain on the mower’s engine, translating to smoother operation and potentially longer equipment life. This blade provides a great all-around performance, capable of efficiently bagging clippings or side-discharging without clumping, making it a dependable choice for weekly maintenance.

Compared to the more specialized Briggs 7041939BZYP mulching blade, this model offers greater versatility for those who switch between bagging and discharging. While it may not produce as fine a mulch, its superior lift makes it a better option for general-purpose mowing. It stands as the benchmark for a no-compromise, factory-spec Briggs and Stratton lawn mower blade replacement that prioritizes performance and fit over the lower cost of some budget options.

Perfectly balanced for smaller machines, the Briggs and Stratton 1687017SM is the definitive solution for mowers with 20-inch decks. Finding an exact-fit OEM blade for less common sizes can be a challenge, but this genuine part eliminates the guesswork, guaranteeing correct fitment and rotational balance. Its primary strength lies in restoring the precise cutting dynamics for which your specific 20-inch mower was designed.

In use, this blade proves that size-matching is critical for performance. It allows the engine to operate at its optimal RPM without the strain a poorly sized blade can cause, resulting in a noticeably cleaner cut and smoother operation. This 20-inch blade is ideal for navigating smaller yards with intricate landscaping, providing agility where larger blades might feel cumbersome.

Positioned between the more compact 19-inch Briggs 880638BZYP and the common 21-inch models, this blade serves a crucial niche. While the 19-inch blade is built for maximum maneuverability on the smallest mowers, this 20-inch version offers a slightly wider cutting path without sacrificing much agility. It’s the ideal OEM Briggs and Stratton lawn mower blade replacement for homeowners who need this specific size and refuse to compromise on factory quality.

Incredibly versatile, this 22-inch Wave Steel Deck blade is the ultimate multi-tool for lawn care enthusiasts. Its standout feature is a true 3-in-1 combination design that excels at mowing, mulching, and discharging, solving the common problem of needing to swap blades for different seasons or lawn conditions. The unique “wave” contour is specifically engineered to enhance airflow, leading to superior performance across all three functions.

During our tests, the blade’s performance on a larger lawn was impressive, with the 22-inch width significantly reducing mowing time. The enhanced airflow created by the wave design resulted in powerful lift for bagging, leaving very few clippings behind even in slightly damp grass. While mulching, it broke down leaves and grass into a reasonably fine consistency, making it a superb all-in-one solution.

Compared to a dedicated mulching blade like the Briggs 7041939BZYP, this 3-in-1 model trades a bit of mulching fineness for outstanding flexibility. It’s the perfect choice for homeowners with larger properties who demand high performance whether they are bagging spring growth, mulching in the summer, or clearing fall leaves. This blade offers a superior combination of features and performance for those who want one blade to do it all.

Exceptionally efficient, this 21-inch Standard Lift blade is purpose-built for homeowners who prioritize a pristine, manicured lawn. As the OEM 7026691BZYP part, it focuses on one thing and does it brilliantly: creating a powerful vacuum effect to lift grass for a perfectly even cut. This blade is the answer for anyone frustrated with stray clippings left on the lawn after bagging.

In practice, the high-lift design works exactly as advertised, pulling grass blades upright just before cutting and then forcefully propelling the clippings into the bag. On lawns where a clean finish is paramount, this blade leaves behind a carpet-like appearance with virtually no visible debris. Its specialization in lift means it is not the best choice for mulching, as it’s designed to expel clippings rather than recirculate them.

This blade is the perfect counterpart to the Briggs 7041939BZYP mulching blade. Where the 7041939BZYP excels at finely chopping and dropping clippings, this Standard Lift blade is the undisputed champion of clean and efficient bagging. For users who almost exclusively bag their clippings, this blade offers better performance and a cleaner finish than a general-purpose or 3-in-1 blade.

Engineered for unrivaled mulching, the Briggs and Stratton 7041939BZYP is the definitive choice for homeowners committed to nourishing their lawn naturally. This OEM blade features a distinctive, curved design that maximizes the time clippings spend under the deck, recutting them into ultra-fine particles. It effectively solves the problem of clumpy, unsightly mulch that can choke out healthy grass.

This 21-inch blade truly shines when turning grass clippings and dry autumn leaves into a nutrient-rich feed for your turf. The resulting mulch is noticeably finer than what’s produced by all-purpose blades, decomposing quickly and disappearing into the lawn. Due to its lower-lift design focused on recirculation, it is not the ideal choice for bagging, especially in thick or wet conditions where it can struggle to clear clippings.

When compared directly with the versatile 3-in-1 Briggs B019WESXA8, this blade’s specialization is clear. While the B019WESXA8 is a jack-of-all-trades, this 7041939BZYP blade is a master of one, delivering a far superior mulching result. It is the best Briggs and Stratton lawn mower blade replacement for anyone who makes mulching their primary mowing method for a healthier lawn.

Precisely crafted for compact mowers, the Briggs and Stratton 880638BZYP is the essential replacement for specific 19-inch deck models. As a genuine OEM part, it guarantees the correct weight, balance, and dimensions, solving the critical issue of finding a proper-fitting blade for less common mower sizes. Using this blade ensures your smaller mower performs efficiently without the engine strain or vibration caused by incorrect parts.

This blade is perfectly matched to the aerodynamics and power curve of 19-inch mowers, delivering a sharp, clean cut that maintains the health of your grass. Its compact 19-inch length makes the mower highly agile, perfect for navigating tight corners, garden beds, and other complex landscape features. It offers reliable, standard performance for homeowners who primarily bag or side-discharge their clippings.

For owners of these specific compact mowers, this blade is a non-negotiable component for proper maintenance. It is more specialized than the slightly larger 20-inch Briggs B00D6FEARA, and installing the correct 19-inch size is crucial for the mower’s long-term health and performance. It represents the only way to restore the original factory cut on compatible 19-inch machines.

Impressively durable, the LikeLion Mower Blade emerges as a compelling aftermarket option for those tired of constantly sharpening blades. Its marquee feature is a tungsten carbide reinforced edge, a material significantly harder than standard blade steel, designed to maintain its sharpness through seasons of tough use. This blade directly addresses the pain point of rapid dulling, especially for users with sandy soil or lawns with frequent small debris.

In our hands-on evaluation, the 21-inch LikeLion blade lived up to its promise of durability, showing minimal wear after cutting through thick grass that would typically begin to dull a standard blade. The Bow-Tie center hole provided a snug, secure fit on a compatible Snapper mower, ensuring a balanced and vibration-free operation right out of the box. The cut quality remained consistent and sharp throughout the testing period.

Unlike a genuine Briggs & Stratton B019WEQ9W2 blade that guarantees an OEM-spec fit, the LikeLion blade bets on superior materials to deliver its value. For homeowners comfortable with high-quality aftermarket parts, this blade offers a tangible upgrade in longevity and edge retention, potentially making it a more cost-effective choice over the long term.
