Question: How Do Mulching Blades Work

Mulching mowers not only create a stream of air that directs the grass up into the mower blades, but once the grass is cut, the clippings hit the blade multiple times before they go back onto the lawn. This is in contrast to other mowers which direct the clippings out the side or into a bag.

Do mulching blades make a difference?

Mulching blades feature more curves and an increased cutting edge. The curved surface and increased cutting edge allows the blade to cut the grass and bring it into the deck where it is cut several more times before falling back onto the lawn in much smaller pieces.

Can you put mulching blades on any mower?

Q: Can you install mulching blades on any lawn mower? There are mulching blades available for most mowers, but not all mowers should have mulching blades installed.

Are high lift blades good for mulching?

Lifting blades come in three types: High-Lift, Medium-Lift, and Low-Lift. Essentially, the greater the lift, the more horsepower that’s required. You would use High-Lift blades when tackling taller, more dense grass (High-lift = higher-lifting airflow). You should not use Lifting blades for mulching.

What is better for your lawn bagging or mulching?

When a gas powered lawn mower runs in reverse, its blade continues to spin in the same direction as it would if the mower were operated in the forward gear. Blade sharpness issues, therefore, can be discounted in powered mowers.

How do I know what mulching blade I have?

The easiest way to tell the difference between mulching and standard lawn mower blades is to look at their shape. A standard blade will have fewer cutting edges and a straight shape, while the mulching blade will have several cutting edges and a curved shape.

How long do mulching blades last?

Depending on your usage lawnmower blades can last at least 200 hours or longer. If the grass is unevenly cut, or a hard object is hit check the condition of the blade. Mower blades normally need to be sharpened every 25 hours, but when the blade is damaged it needs to be replaced.

Does a lawn mower blade spin clockwise or counterclockwise?

Most lawn mower blades rotate in a clockwise direction (counter-clockwise when viewed from below), and as such have the cutting edge on the right side. If you are unsure of how your mower rotates, check the position of the discharge chute; if it is on the right side angled back, the blade turns clockwise.

Which is the cutting side of a mower blade?

To determine which side of your lawn mower blade is up, first figure out which side is the sharp cutting edge, and which side is the blunt edge. Look for a sticker indicating which side goes up and which side faces downward. The cutting edge should face the grass while the dull edge should face the deck of the mower.
