Round vs Flat blade

Mulching blades are made in two varieties: flat and round edges. The flat blade is suitable for thin grass and thick weeds, while the round-edged mulching blades work best on thick grass. They have a wider diameter, allowing more leaves to be shredded at once.

How do John Deere Mulching Blades work? 

John Deere Mulching Blades are created by rolling or grinding a piece of metal into a circular shape with serrated edges on every segment that faces inwards towards the blade’s center. The type of material used to make the blade determines its thickness and width, which dictates how much fuel it needs to run at maximum speed. A one-inch John Deere Mulching Blade is thicker than a one-and-a-half-inch blade, requiring more power from the lawnmower to run.

Features of John Deere mulching blades

A John Deere mulching blade has several features that make it useful in the everyday functioning of the lawnmower. Some of these features are:

1. Multi-rib design: The mulching blade has an extra rib on each side of the blade to form a protective shield that keeps the mower’s engine cool. The multi-rib design also reduces wear and tear on the engine since there is a rib in every blade segment. This means that each part of the blade will hit a different rib and thus be spread out evenly across all aspects of the mulching blade when it hits them, instead of being concentrated on one site.

2. Aggressive jaw: This feature also serves as a multi-rib design since the group of ribs secures the mulching blade in place on the mower’s engine. This can help prevent wear and tear on the mower’s engine, saving money on repairs.

3. Split point: The split point is located at the top of the John Deere mulching blade and is used to increase its efficiency. Since this tool has to run at high speeds and chop up fruits closer to it than grass, efficient energy must be made possible.

4. Dual material: There are mulching blades made from carbide steel and polygonal carbide, and this feature can help determine the sharpness of the blade. Carbide steel tends to dull a little faster than polygonal carbide but is sharper when it first begins operating. Polygonal carbide lasts longer than carbide steel but dulls more slowly. Use both kinds of materials to get the best out of your mulching blades.
