Introduction

Our (3x) New Aftermarket Replacement Mulching Blades are designed to fit John Deere Models: D170, G100, G110, LA150, LA175, 190C. They have a length of 18-5/8" and a center hole of 7 Lobe. These blades can replace GY20684 and GY20686.

Common Uses

The Mulching Blades are mainly used in commercial and residential mowers to mulch grass into very small pieces, which are then discharged back into the lawn. This technique is very useful for lawn health, as it recycles the lawn nutrients back into the soil. The blades are also good for reducing the volume of grass clippings, making the lawn look much cleaner after mowing.

Advantages

• Long-lasting: Made from high-quality materials, they have a very long lifespan.
• Efficient: The blades reduce the volume of debris and return valuable nutrients to the lawn.
• Easy to install: With a 7 Lobe center hole, the blades fit perfectly on John Deere Models.
• Cost-effective: They are an affordable alternative to OEM blades.

Material and Installation

The Mulching Blades are made of durable materials, which ensure high performance and durability. We recommend that you install the blades when the mower is parked on a flat surface. First, remove the old blades, then use a torque wrench to tighten the new blades to the recommended torque. Always refer to the manual for the recommended torque specifications.

Maintenance and Replacement

To maintain the blades' performance, always keep them clean and sharp. If the blades become damaged, they should be replaced immediately. We recommend replacing all three blades at the same time to ensure consistent performance.
