A well-maintained lawn can prevent waterlogging and the growth of mold, reducing the risk of pests damaging the lawn. Despite using advanced lawnmowers, it may not get ideal mowing results. Today, we’ll share how adjusting the lawn mower blades can improve mowing results and save you time.


How a mower works?

Lawnmowers operate by harnessing the power of a gasoline engine. A transmission system drives a cutting disc to rotate at high speed. Attached to this disc is a specialized polymer line (or cutting cord) which rotates synchronously, generating cutting force to trim weeds effectively.

How to adjust lawn mower blades?

Disconnect power

Always ensure the lawnmower is powered off and disconnected before adjusting the blades.

Check blade condition

Inspect the blades for any damage or wear. Replace them if they are dull or damaged.

Determine the ideal cutting height

Adjust the blades to the desired cutting height using the mower’s height adjustment lever.

Calibrate blade angle

Ensure the blades are level for even cutting. Use a level or other tool to verify the blades are horizontal.

Inspect the mower underside

Clear any debris or fragments from the mower’s underside that may affect blade operation.

Tighten blade screws

Tighten the blade screws, then turn them back 1/4 to 3/4 of a turn before securing the nuts. Ensure the blade can move freely by gently nudging the blade. If the screws are too tight, the blade won’t rotate.

Blade rotation test

After completing adjustments, test the blades by running the mower for a minute. Check the screws, if they feel hot, they are too tight, and adjustments are needed.

What should I pay attention to the mower blade when mowering?

When using a lawnmower, it’s crucial to protect the blades. During operation, dense grass may clog the blades. In such situations, swiftly raise the front end of the lawnmower and power it off to prevent damage to the motor.

How to choose the right lawn mower blades?

Multi-blade lawnmower blades (gear-shaped) and double-blade lawnmower blades (rectangular) are both suitable for high-speed grass cutting. Compared to rectangular blades, gear-shaped blades are safer. If you want a larger cutting area, you can choose rectangular blades.

For grass shredding, powerful multi-toothed atomic lawnmower blades are ideal, as they can shred grass and leaves into fine pieces without affecting appearance. If grass collection is preferred, blades with collection capabilities are suitable.

For regular lawn trimming, standard straight-edge blades are suitable, while serrated or multi-blade blades are better for long or thick lawns.

Final thoughts

To achieve good cutting, it is crucial to get proper blade adjustment. We all know that dull blades not only affect grass cutting but can also damage the lawn. To maintain sharp mower blades, apart from ensuring correct adjustment, timely and proper blade sharpening is necessary.
