Factors to consider while buying a lawn mower blade sharpener

A normal homeowner may find it difficult to choose the best blade sharpener by looking at the plethora of brands available. The choice may, however, become easier if the following factors are considered thoroughly by the user before making the final decision.

Design Scheme

The user needs to remember the main aim of buying a lawn mower blade sharpener in the first place. If the sharpener needs to be bench mounted then all the sharpeners that do not show this design attribute need to be discarded from the choice matrix. This factor includes the quality of the blade sharpener too. Often times, we have seen that we get what we pay and there is no point in expecting an industrial level performance from a cheap apparatus. It thus becomes important to check out multiple reviews of different brands before zeroing down on one.

Speed according to the usage

In this world where everyone is hard-pressed for time, every homeowner, as well as lawn care professional, wants a blade sharpener that does not take up too much of their time. At the same time, it should not be too fast as the resultant heat may create security issues, not to mention security concerns that may crop up if the sharpener is too fast and creates too much vibration. This becomes a question of balance where the sharpener needs to be fast without compromising on safety or performance.

Safety & Security

Any time a user is handling tools with sharp edges such as lawn mowers or kitchen knives, the factor of safety automatically rears its head. The user needs to see the design scheme and evaluate if it exposes any dangerous edges that may lead to injuries. Also, the inclusion of safety features such as eye guards makes it easier to make a safe choice.

User-friendliness & durability

Some users have never used a blade sharpener in their life and need a tool that doesn’t give them grief while installing or using it. Some users are right-handed while others are left-handed and both kinds need a versatile blade sharpener. This makes the factor of ‘user-friendliness’ pop up. Meanwhile,  it is also important for the lawn mower blade sharpener to give a value-for-money performance and last an appropriately long time or it might turn out to be an expensive proposition if it needs parts replacement every now and then.

Extra features

A lawn mower blade sharpener is equipped with different parts such as grinding motor, stones, abrasive belts and so on. Not every sharpener has every part and not every user needs them all either. It is important to understand the purpose for which the sharpener is being bought and accordingly the inclusion or absence of any extra feature can be judged. There is no point in paying extra bucks for some features that remain fantastic on paper but are never used in the real world and vice versa.


Frequently Asked Questions

How to use a lawn mower blade sharpener?

The best way to understand how to use a lawn mower blade sharpener is to browse through the accompanying manual for users. Every blade sharpener has unique functionality and specific security instructions that must be followed.

How often to sharpen lawn mower blades?

The frequency and the usage pattern of the lawn mower decide on the frequency of the sharpening of its blades. For those who use their lawn mower rarely or purely for domestic purposes, even a once-a-year-sharpening ritual might be enough. For others who may be nurturing their landscaping business, a heavy-duty blade sharpener may be needed that can sharpen blades perfectly every month. As a general rule, it is wise to get the blades sharpened as soon as they start looking dull or full of burrs.

Types of lawn mower blades?

There are two main types of lawn mower blades- Standard and Mulching. Standard or 2-in-1 blades perform the tasks of cutting the grass and discarding the grass clippings. On the other hand, Mulching or 3-in-1 blades provide an extra option of depositing the grass clippings back into the soil in much smaller sizes. This may increase the nutrition content of the soil and is most ardently used by lawn care professionals.

What angle should a sharp mower blade have?

The sharpness of the mower blade needs to be maintained for a long healthy life of the blade and for consistently beautiful performance on the lawn. Usually, 30-45 degrees angle is considered good enough to provide a consistently sharpened blade.

Can I sharpen my mower blades with a power drill?

Yes. The usage of a power drill with a powerful grinding wheel or stone is fast gaining traction when it comes to mower blade sharpening. The usual rules apply here, to see the usage of the lawn mower and sharpen it accordingly, once a year or once a month.

How tight should mower blades be?

The tightness of mower blades ensures the safety of the lawn mower user once the sharpening of the blade is done and it is reattached to the lawn mower. Tightening it to between 70-80 pounds of torque is the most common step taken by the users.

How sharp should your mower blade be?

This is a delicate balance that the user must always strive for, ensuring that the blade is neither too dull nor too sharp. In the former case, it will become redundant too soon, and in the latter, it will damage the grass. It should not be sharp enough to cut anyone’s hands-on touching it but also not soft or dull enough to have no effect on the lawn.

Conclusion

The market is full of brands claiming to provide the only lawn mower blade sharpener worth checking out, but we know that is not true. One needs to consider multiple factors before zeroing down on the blade sharpener that would keep every lawn looking fresh. It is a tool not used for vanity but for increasing the beauty of the lawn and the lifespan of the lawn mower blade that would otherwise be headed to a retirement home within a year of its purchase. After considering different factors, this buying guide has come up with the best of the lot in different budget segments that would surely help everybody in the lawn care industry.
