It performs exceptionally well in taller or thicker grass, preventing clumping and leaving a clean finish. While it is a champion of bagging, its design is not optimized for mulching, as it focuses on moving clippings out, not chopping them up.

How to Choose the Right Briggs & Stratton Lawn Mower Blade Replacement
Replacing your Briggs & Stratton lawn mower blade is essential for maintaining a clean, even cut and prolonging the life of your mower. With several options available, it’s important to choose the right blade based on your mower model, deck size, cutting needs, and material quality.
Match the Blade to Your Mower Model and Size
Ensure the replacement blade fits your specific Briggs & Stratton mower. Check your owner’s manual for the correct part number or deck size. For example, the Briggs & Stratton 20″ 1687017SM Blade fits 20″ decks, while the 40″ Mower Blade is designed for larger mowers. Using the wrong size can cause vibration, poor cutting, and damage to the engine.
Choose the Right Blade Type for Your Lawn Needs
- Standard Lift Blades (like the 7026691BZYP) offer balanced airflow for regular bagging and side discharge. Ideal for general mowing.
- Mulching Blades (such as the 7041939BZYP) have extra curves and edges to chop grass finely and return nutrients to the soil. Best if you don’t bag clippings.
- High-Lift or Performance Blades improve suction for better bagging in tall grass.
Prioritize OEM or High-Quality Aftermarket Parts
OEM (Original Equipment Manufacturer) blades like those from Briggs & Stratton ensure perfect fit and reliability. The 1731898BZYP and 1737228BZYP are genuine parts made in the USA, offering durability and consistent performance. For budget needs, the 1737228BZYP delivers value without sacrificing compatibility.
Consider Blade Material and Durability
Most blades are made from hardened steel, but the LikeLion 21″ Stainless Steel Blade stands out with tungsten carbide coating for extended sharpness and rust resistance. Stainless steel blades last longer and resist corrosion—ideal for wet or humid climates.
Check Installation and Safety Features
Most blades install quickly with basic tools. Always disconnect the spark plug before replacing. Look for blades with clear markings and standard hole patterns (like bow-tie center) for easy alignment. Wear gloves during installation for safety.
By matching the blade to your mower size, choosing the right type for your lawn care routine, and opting for durable materials, you’ll ensure a cleaner cut and better mower performance.

Data-Driven Blade Selection: Testing & Analysis
Choosing the optimal Briggs & Stratton lawn mower blade replacement requires moving beyond simple compatibility. Our analysis focuses on performance data and user feedback related to different blade types – standard lift, mulching, and high-lift – across varying grass conditions. We examined online retailer data (Amazon, Lowe’s, etc.) to correlate blade purchase frequency with user reviews mentioning cut quality, bagging efficiency, and durability.
Comparative studies on lawn care forums and review sites reveal that mulching blades (e.g., 7041939BZYP) consistently receive higher ratings for lawns where clippings are left in place, while high-lift blades (often used with bagging systems) are favored for taller, thicker grass. Material analysis indicates that while hardened steel blades are common, stainless steel options like the LikeLion blade demonstrate superior rust resistance, particularly relevant in humid climates.
We also assessed the price-to-performance ratio of OEM vs. aftermarket blades, finding that while OEM Briggs & Stratton blades (e.g., 1731898BZYP) offer guaranteed fit, several reputable aftermarket brands provide comparable performance at a lower cost. Data suggests prioritizing blades with standard hole patterns (bow-tie center) to simplify installation and minimize potential engine strain. This data-driven approach helps identify the best lawn mower blade for specific needs and ensures informed decision-making.
