How to Choose the Best Lawnmower Blade Sharpener:

The following are the must to consider various key factors while shopping for a lawnmower blade sharpening tool. This will help you pick the right option suitable for your requirements.

1. Speed:

One has to consider the speed of their sharpener to know how fast your grinder will sharpen the mower blades. This determines the time you spend sharpening the mower blades. Usually, the sharpener will sharpen the blades in either manual (handheld) or electric (grinders).

Manual Sharpeners – It is a bit time-consuming process that takes around 30 minutes to a couple of hours to achieve the desired edge.

Electric Grinders – These grinders take less time (within a few minutes) to sharpen the blades compared to their counterparts. However, the speed depends mostly on the particular grinder’s horsepower and RPM speed (number of times the grinding wheel spins per minute). The higher the RPM, the blades will have the better, sharp, and smooth finish.

Keep in mind that the fastest sharpener won’t always consider the best option. All you need is to select and use a sharpener whose speed relates to the blade, why because the excessive speed will generate overheat and thereby damage the blade. Also, it might cause injury to the operator.

2. Power Type:

Manual and electric are two types of power sources available to sharpen your lawnmower blades. Here the manual models are cheaper, yet need lots of time and labor to sharpen the blade than electric-powered models. You can sharpen the blades quickly and easily with a model running on an electric motor. You can choose either of these blade sharpener types as per your requirements.

3. Motor Power:

If you buy a powered lawnmower blade sharpener using an electric motor for spinning the grinding wheel, then check its motor power. High motor power will let you use the blade sharpener even for heavy-duty applications without any issues.

Most blade sharpeners offer motor power mentioned as 1/4 HP or 1/2 HP, and as you would expect, the higher power rating of 1/2 HP will result in a better performance. It let you sharpen a lot of blades within a short time.

4. Usage:

Based on your usage, you have to pick the right type of sharpener from the range of hand-held, heavy-duty angle grinding wheels, and powerful motor grinders.

A professional, industrial-style grinder is not required to sharpen a compact mower blade. Similarly, a cheap hand-held sharpener is not used to sharpen a professional landscaper sharpening blade for commercial or large-scale settings. Instead, look for a professional solution that lets you sharpen multiple lawn mower blades. Moreover, you should know how often and how you use the tool before buying these sharpeners.

5. Guide Material and Durability:

These sharpeners have a guide used to control the angle of sharpening, which confirms the blade to stay at the correct angle without shifting. Mostly, these guides are constructed with plastic material. If it is made of low-quality plastic, then it might overheat, melt, and generate smoke.

Also, applying too much force while sharpening will melt this plastic guide. So, this plastic used to build a guide should be strong and durable that won’t easily break or melt. Moreover, you have to check the online reviews and ratings before buying a product.

Some guides have a problem with mulching blades. If having a mulching blade, then ensure to check if the dull lawnmower blade works in your selected guide.

6. Sharpener Material:

It refers to the grit grinding away the blade’s metal. Based on the sharpener type, the use of sharpener material will vary. Usually, corundum and carbide are two components used in blade sharpeners, which are harder than metal on the blade and thereby offer perfect sharpening results.

Corundum (hydrated aluminum oxide) is a common material used widely for drill-type sharpeners. This hard material will provide the essential strength required to shave down the blade edges. While carbide is a carbon-heavy metal used widely in handheld sharpeners. Its excellent molecular structure offers the required strength to make it work as a sharpener.

7. Compatibility:

Some sharpener models are traditional blade files and grindstones, which are used to sharpen any type of blade, while some other models have compatibility issues. So, ensure to select the right model (according to your needs) for the perfect sharpening of the blades without any issues.

If using power drill-attachment sharpener type, where you have to fit the sharpener to the drill for producing the required force. Then you have to check whether your drill is compatible with these attachments or not.

Moreover, you have to check the blade size (usually 5 or 6 inches) and sharpener angle (30° or 40° grinders) to sharpen the mower blades. If a blade sharpener is not fully compatible, then it won’t sharpen the blades and might result in causing issues while cutting grass with this mower blade.

8. Ease of Use:

The ease of use is an essential factor to check before buying any product, including this blade sharpener. Irrespective of its type, you have to use it intuitively. For instance, using a drill attachment sharpener type, then you should keep it in the drill with ease.

Ergonomics play a key role in this ease-of-use feature, and you should be comfortable while using this sharpener to sharpen the blade without much strain or effort. For this, check the reviews to know whether the product has proper ergonomics or not.

Especially for left-handed users, they should check if the product is designed to use for lefties. Usually, most models are meant with right-handed people, so ensure to check the feature for your comfort and ease of using the sharpener before buying.

9. Versatility:

Even these are labelled as lawnmower blade sharpeners, but they are versatile and can be used to sharpen several different types of blades. It is an excellent option for gardeners who use varied blades, which are used to sharpen all these blades.

Remember that sharpener will sharpen one type of blade while destroying the other type. For example, using a heavy-duty commercial sharper is a perfect option for large mower blades (or other large blades), yet damages the thinner blades.

While some sharpener models are used to sharpen standard blades, high-lift, mulched, and others. So, you have to decide based on your sharpening requirements that your tool should be versatile without damaging other blade types.

10. Safety:

Though blade sharpening is essential for those who work regularly, yet it can be dangerous and cause accidents, if not paid proper attention to it. So, prefer to choose a model having some safety features to safeguard you from friction, cuts, or sparks.

  • Handheld sharpener offers finger guards as a minimum safety feature, why because the fingers are most exposed and suffer a lot from bruises or cuts. Mostly, these guards are oversized that let you use them after wearing gloves.
  • Purchase eye protection or goggles separately while using motor grinders to prevent sparks and metal fillings from affecting your eyes.
  • Safety gloves, and a protective apron or non-flammable clothing are suggested while using these sharpeners.

11. Durability:

It is essential to pick a strong, durable and long-lasting lawnmower blade sharpener to improve the life of blades and make them used for a long time. Usually, sharpeners made of carbide are much more durable and offer a longer warranty period.

12. Price:

Different sharpener models come at different price rates that depend mostly on their features, built quality, and construction material. The general price range of the sharpeners will be from $5 – $300 (or more). For instance, a handheld sharpener will cost you less than a heavy-duty grinder. There is a proper balance between your needs and budget range to buy a sharpener. Yet be sure that the sharpener you choose/purchase is worthwhile.

13. Warranty:

The warranty offered by most manufacturers will vary from one sharpening tool to another, as it provides peace of mind if anything happens wrong. Check the warranty, and return policy before making its purchase, why because some models won’t offer any warranty. In general, a lawnmower blade sharpener offers a warranty of 1 or 2 years against its manufacturing defects.

Types:

There are several types of lawnmower blades available, in which each one has a different approach to make the blade for a perfect, smooth, and sharp cutting. As a user, you have to know which type of sharpener is suitable for a particular work. Don’t use a power tool for sharpening a ride-on mower to mow a massive yard. Similarly, use a hand-file for small push mower blades to mow on a small patch.

This type is an ideal option for lawn mower blades used to mow small grassy spaces, but not for medium-large yards. It is an eco-friendly and versatile sharpening tool that can easily sharpen household knives and other sharpening tools. Yet it takes elbow grease more than other types and is also a time taking process. It requires a minimum of 30 pulls per one side of the blade. So, it won’t be an efficient option as powered types.

Here the drill attachments use a ¼-inch hex for connecting to any of your drills. It is made of beveled corundum and has a guide that lets you precisely position the blade. After connecting to the blade’s angle, it smoothes out the blade with its rapid rotations. Though you require more time to set up, yet need less time in its application. An inexperienced user can easily use drill attachment, yet results in an off-balance. So, this type is the perfect option for experienced users and mowers used for medium yards.

This handheld tool is the expensive, powerful, and most preferred option by several landscaping professionals that can be operated with an electric cord or rechargeable batteries. With its rotating disc, this tool will connect to the blade edge at an angle, which is hand-controlled. Multiple handles in several models will let you have a proper balance of control and speed.

It is an ideal option for commercial settings or large yards, as its disc design is less prone to damage the integrity of the mower blade. With a dedicated disc, you can sharpen multiple tools with this type, which ranges from metalworking to construction.

How to Use this Lawnmower Blade Sharpener?

Though sharpening your mower blades might be threatening at first, yet with the use of the right tools, the process is simple and easy. Just remember that specifications will vary based on the type of mower. For instance, a ride-on mower is not at all same as a push mower, even though they are used for the same purpose.

Here is the detailed step-by-step procedure that explains how to use this sharpener to sharpen your mower blades.

1. Setting Up – 

Before you make use of this sharpener, you need to set up a few things like a clean workspace, tools, or sharpening supplies (includes power supply when using electric unit) handy.

Also, a set of adjustable wrenches to take out the blades.

2. Remove the Blades – 

Turn off the mower and disconnect it from the power source. To prevent spills, you have to drain the gas tank and then place the mower on its side to confirm that carburetor and filter have to face upwards. For this, use a marker to mark the blade’s bottom. Locate the nut connecting the unit’s blade and loosen it with a wrench till the blade releases. Cover it with dry bits of grass and dirt that let you need to clean it.

3. Clean the Blades – 

After separating the blades, clean the surface with the help of a dry cloth. Also, apply lubricant if any particulate is ingrained on the blade. Leave it for a certain time to get dry and clean and then use it for sharpening.

4. Blade Setup and Sharpening Tools (Hand Files, Drills, & Grinders) – 

Grip the blade in proper position with a vice grip to clamp it in a place for its sharpening. Ensure that blade’s cutting edge should face upwards. Also, look for any crack or dent to make is sharpening is a better option compared to replacing. Now get ready to sharpen the blade with any type of tool.

Keep the sharpener at the top of the blade’s cutting edge, and move the file in one direction with a grain. However, moving forth and back will damage the blade and sharpener as well. You feel protrusions on the blade if not applying the proper amount of pressure while moving the sharpener. Or else apply a little more force to keep the sharpener working over the blade’s perfect angled edge. Usually, it needs less than 50 file strokes to sharpen the blade. After smoothing all rough patches, you have to flip them to continue the same process on the other side.

Gloves and eye protection is must to wear accessories to use this power tool. Just like a manual hand tool, you have to do the same clamping process. A ¼-inch shank along with a guide piece is used by standard drill attachments. Here the beveled side offers a proper angle while sharpening and then hook it to the drill. Turn on the machine and a guide should be placed against the rear of the blade. Thus, the blade’s edge has to fit perfectly into the bevel to provide a precise angle to sharpen. Ensure to use a low-medium pressure to run the sharpener on the blade, and not more than 2 passes per side.

It is used by professionals to do the sharpening task efficiently and with ease. Simply clamp the blade as other methods, then set this grinder with a flap disc. Usually, several sets come with this part. The cutting edge of the mower blade is lined with the grinder blade. move the grinder back and forth with minimal pressure. Also, smooth the rough patches of the blade’s edge by tracing its angle.

5. Blades Balancing – 

Balancing the blade is essential for its even sharpening. If not, one side grows lighter than the other side and thereby affects its performance as wobble, which, in turn, results in extra vibrations and damage the mower. To get rid of this issue, balance and hold the blade with a screwdriver on the handle laterally. It has to be in that position, and in any case, it lowers, then you have to sharpen the blade, where it has lowered to make it even.

6. Re-Install the Blades – 

After even sharpening of the blades, you have to re-install them onto the mower. For this, remove the leftover debris or grass to clean the area. Then take your blade and check the identifying mark you kept while taking it out. Now insert the blade onto the bolt and tighten using a socket wrench till you confirm it is properly installed. Refill the tank (for a fuel-powered unit) or reconnect the parts (if using an electric model).

7. Mow – 

Test whether the mower starts and functions properly, then run it on a patch to ensure that everything is working properly (cuts evenly and smoothly). You need to sharpen the blade a minimum of twice a year to make your mowing process simple, quick, and easy. Set this sharpening as your regular maintenance to enjoy a proper and nice-looking lawn without purchasing new blades.
