A well-maintained lawnmower is essential for a healthy and beautiful lawn. One crucial aspect of lawnmower maintenance is ensuring the blades are sharp. Knowing whether or not your lawnmower blades come sharpened from the factory can save you time, effort, and potentially damage your lawn.
Do Lawnmower Blades Come Sharpened?
The answer is not always a simple yes or no. While some lawnmower blades are factory-sharpened, others are not. It varies depending on the brand, model, and type of lawnmower.
Factors Affecting Blade Sharpness
Here are some factors that influence whether a lawnmower blade comes sharpened:
- Manufacturer: Some manufacturers prioritize providing sharp blades out of the box, while others leave it to the user.
- Model: Higher-end models often come with factory-sharpened blades, while budget-friendly options may not.
- Blade Type: Specialized blades, such as mulching or bagging blades, might be sharpened differently or require sharpening more frequently.
Do Lawnmower Blades Come Sharpened?
A common question among new lawnmower owners is whether or not their blades come sharpened. The answer is: it depends.
New Lawnmower Blades
Most new lawnmower blades are shipped from the factory with a factory edge. This means they are not razor-sharp but have a basic bevel that allows them to cut grass. Think of it like a new pair of scissors – they’ll work, but they won’t be at their optimal cutting performance until they are sharpened.
Why Aren’t They Razor Sharp?
There are a few reasons why manufacturers don’t ship blades razor sharp:
- Cost: Sharpening blades adds to the manufacturing cost.
- Shipping Damage: Extremely sharp blades are more prone to damage during shipping and handling.
- Safety: Extremely sharp blades pose a safety risk to both consumers and factory workers.

Conclusion
While some new lawnmower blades may have a factory edge, it’s best to sharpen them before your first use and regularly thereafter to ensure optimal cutting performance and a healthy lawn.
In conclusion, the sharpness of lawnmower blades is a crucial factor in achieving a healthy and aesthetically pleasing lawn. While some lawnmower blades may arrive slightly sharpened from the manufacturer, it’s generally recommended to sharpen them before each mowing season or as needed.
