Detailed Buying Guide: How to Choose the Right Briggs & Stratton Blade
Replacing your lawn mower blade is essential for optimal mower performance, healthy grass, and clean cuts.
When selecting a replacement blade for a Briggs & Stratton powered machine, you must focus on four key areas: compatibility, blade type, material quality, and whether to choose OEM or aftermarket.
1. Match the Blade to Your Mower Model
Always verify compatibility with your specific mower model. Check your mower’s model number and cross-reference it with the blade’s OEM part number (e.g., 703371 or 1737228BZYP).
Using the correct part ensures a secure fit and proper balance, which is vital for preventing deck vibration and potential damage to your engine or spindle.
2. Choose the Right Blade Type for Your Lawn Needs
Different blades are specifically designed for distinct cutting tasks:
- Standard Lift Blades (e.g., 21″ Standard Lift Blade) are the classic choice, providing strong suction for clean discharge and are best for regular mowing and bagging.
- Wave or 3-in-1 Blades (e.g., 22″ Wave Blade) are versatile, supporting mulching, bagging, and side discharge. Their curved design is engineered to improve airflow and enhance grass clipping breakdown, which is ideal for achieving healthier lawns.
- Mulching Blades (e.g., LikeLion 703371) have extra curves and cutting edges designed to finely chop clippings and efficiently return them to the soil as fertilizer.
3. Prioritize Durable Materials
While standard steel blades perform well, they tend to dull faster. For extended life and reduced replacement frequency, you should choose high-quality steel or stainless steel blades. Premium blades, such as the LikeLion 703371, may feature a tungsten carbide edge which resists rust and wear, helping the blade stay sharp longer.
4. Decide Between OEM and Aftermarket
- Genuine OEM blades (Original Equipment Manufacturer), like the Briggs & Stratton 703371 OEM Blade, are guaranteed to be engineered to the manufacturer’s exact specifications, ensuring peak performance and reliability. They typically offer better balance and durability but often come at a premium price.
- Aftermarket options (like LikeLion) can save you money but the quality varies. While some aftermarket blades offer material upgrades (like tungsten carbide), it is crucial to check customer reviews carefully regarding fit and balance before purchasing.
5. Consider Blade Size and Installation
Always ensure the blade length (e.g., 21″, 22″, 40″) precisely matches the length required by your mower deck.
Most replacement blades can be installed quickly, often in under 10 minutes with basic tools. However, always follow safety practices, including wearing gloves and disconnecting the spark plug before attempting installation.
By focusing on the correct fit, function, and material durability, you can keep your Briggs & Stratton mower cutting cleanly and efficiently for seasons to come.
