A GUIDE TO THE LAWN MOWER BLADE SHARPENING TOOL

A lovely lawn is an awesome addition to any home. This only became clearer to me when I hired my landscaping expert. Five years down the line I have realized what a valuable addition the lawn has been to my home. The only thing that now works differently is that I engage in a DIY lawn maintenance practice – at least it gives me a better chance to learn many things about how to keep my lawn clean, fertilize it, and the right tools to work with. My latest addition is the lawn mower blade sharpening tool.

So what is a lawn mower blade sharpening tool? It is a gadget that helps you to maintain your mower’s efficiency. It makes it easy for you to sharpen the mowing blades and thus provides you with a chance to have the classic trim for your grass. A lawn mower blade sharpening tool can be bought online and also within any hardware. At local hardware, the prices could double due to additional costs. So if you want a better bargain, I would advise you to buy a lawn mower blade sharpening tool online.

MAIN FEATURES OF A LAWN MOWER BLADE SHARPENING TOOL

The lawn mower blade sharpening tool comes in a variety of types. This means that you could get different features for a different type of mower that you choose. However, there are many common features a sharpening tool for lawn mower blade will have irrespective of brand. They include the following.

A Mounting System

This can come in a T-Slot style. It is often adjustable and allows you to mount the lawn mowers blade securely on the sharpening tool. Some mounting systems double up as handlebars for lifting the tool.

Grinding Wheel

This is the most important part of a lawn mower blade sharpening tool. The best that I have used had a 150 mm tempered glass grinding wheel. However, when buying you should ensure that your grinding doesn’t burn blades; if you get one that doesn’t need the dressing that will be cool too.

Quick Change Guards

This provides fast grinding wheel removal (it increases burr removal) and in some other machines can also be used to speed up sharpening.

Sharpening Ports

The use of sharpening ports in a lawn mower blade sharpening tool is to provide precise and repeatable sharpening angles. The most common angles that you will find are 20”, 25”, 30”, and 35” ports among others.

Bench Mount Tabs

These are usually to facilitate a stable and compact mounting on the sharpening station. It prevents the tool from slipping or falling while working with it. Such accidents can be fatal so care is vital. Some designs will come to require to be bolted down while others come with rigid designs.

Vision Guards

These can be slotted see-through plates or tempered glass guards that protect your eyes and also your face from any forms of files and metallic clipping that are released while you are sharpening your blades.

Power Cables

The power cables allow you to plug in your lawn mower blade sharpening tool to a power source before you start working with it. Always make sure that both the tool’s switch and the electric power source are both switched off before plugging in the cable.

TOP FIVE CONSIDERATIONS WHEN BUYING A LAWN MOWER BLADE SHARPENING TOOL

There are so many factors that should look into if you want to buy a Lawn Mower Blade Sharpening Tool. Here are the most basic ones.

The Size of Your Work Bench/ Space

Do you have enough space to mount the sharpening tool? Without enough space, fixing your sharpening tool could be difficult. Worse still, you may not enjoy the freedom of moving about when working. Workshop accidents also tend to take place in very small/ inadequate spaces.

The Price of the Sharpening Tool

The price is often a reality. You cannot buy what you cannot afford. And even if you could afford it, you do not want to buy impulsively. Because of this choice, the right tool is a very fundamental aspect of any Lawn Mower Blade Sharpening Tool when you choose to purchase it.

The Durability/ Technology of the Tool

A tool with face guards, inbuilt mountings, quick change guard, non-maintained sharpening/ grinding wheel will most definitely appeal to your lawn mowers sharpening needs. Indeed we all require something really simple to work with but which is also efficient and has high style tech.

How Often You Will Use the Sharpener

This is another very important consideration. If you have a ranch, you could mow so many times a week. What this means is that your lawn mower blades could go blunt often and thus you’d be forced to use the sharpening tool frequently. The higher frequency increases the rate of wear and tear. Therefore you need something really durable.

The Cost of Care and Maintenance

While warranties and after-sales services could bring the figure down, there is no guarantee that they will last a lifetime. In short, you will have to take up the costs of care and maintenance alone someday. Because of this, you should look for a mower that is budget-friendly to you and your wallet.

CARE AND MAINTENANCE OF THE LAWN MOWER BLADE SHARPENING TOOL

If you want your Lawn Mower Blade Sharpening Tool to last longer, you will need to take care of it properly. Generally here are some of the ways that you could do that.

  • Read/ use the correct user manual
  • Choose a lawnmower blade sharpening tool that has warranties and after sale services.
  • Oil the movable parts of your sharpening tool at least twice a month.
  • Seek the expert’s advice every time you don’t understand how to use it.
  • Make sure you keep your lawn mower blade sharpener out of children’s reach always.

HOW TO SHARPEN LAWN MOWER BLADES

Preparing the Blade for Sharpening

  1. Disconnect the power source (outlet or battery) before you disassemble the mower. Also, disconnect the spark plug wire from the spark plug. Tape or tie it, so it doesn’t go back into contact with the plug. It will prevent the lawnmower motor from starting while you’re working on it. For safety, wear eye protection and gloves.
  2. Turn the lawnmower onto its side with the carburetor and air filter facing up. It will prevent gas and oil from dripping into the air filter.
  3. Mark the downward facing side of the blade. One common mistake many people make when sharpening lawnmower blade is re-installing it upside-down. If this occurs, even a sharp blade won’t be able to cut grass if it’s upside-down. You can mark the bottom of the lawnmower blade with a grease pen, masking tape, or any object that can create a visible mark.
  4. Wedge a block of wood between the blade and the mower deck to keep the blade steady. You can also use a clamp or vise. Loosen the bolt or nut by using a long-handled wrench. Turn counterclockwise. Then, remove the bolt and blade.
  5. After you’ve removed it, clean the blade of rust and grass clippings. For ordinary cleaning, all you need is a dry rag. But, if it has been a long time since you’ve cleaned the lawnmower, it may be necessary to use a hose and soapy water to remove accumulated dirt and grime. Then, dry the blade with a rag.

Sharpening the Blade with a Metal File

  1. Using a vise or clamp, secure the lawnmower blade. Ensure that the blade will stick out over the edge of the workbench at waist-level, so you can work on it while sitting.
  2. To sharpen the blade, run a metal file along with the cutting edge. Stroke from the inside edge to the outside edge of the blade until a shiny edge is apparent. Flip over the blade then repeat the same process on the other edge. To protect your lungs from metal particles and dust, wear a face mask.
  3. As you sharpen, keep the metal file at the angle of the bevel of the blade. Usually, the blade angle is 40 or 45 degrees. However, it’s not always the case. Check the manufacturer’s manual for the exact angle. Lawnmower blades do not have to be razor sharp as they spin fast enough to cut grass. If the blade is as sharp as a butter knife after you finish, that is good enough.
  4. Spray some WD-40 on the main bolt to prevent rust. Then, put the blade back on the lawnmower, followed by washers and the bolt. Tighten the bolt using a wrench or ratchet. Ensure that the blade is correctly oriented when you mount it (this is easy if you marked the downward facing side of the blade). The sharp edge should face the direction of the spin.

Sharpening with a Machine

  1. Observe safety precautions while working. A bench grinder or other blade sharpener machines can fling tiny pieces of debris at high speeds, potentially causing injury. To protect yourself, wear eye protection, long sleeves, and gloves.
  2. To sharpen it, move the blade back and forth against the wheel of a bench grinder. Maintain the original angle of the bevel of the blade as you sharpen it. You can also use a 4 ½ inch angle grinder with a metal wheel. But keep in mind that if you want to sharpen lawnmower blade, a bench grinder will do a better job than an angle grinder.
  3. Another way to sharpen a lawnmower blade is through the use of a belt sander. Rub the blade at an angle against the sandpaper to sharpen it through friction.
  4. The friction that results from sharpening with a machine can cause a blade to overheat. This can cause warping or weakening. To prevent this from happening, quench the blade as it is being sharpened. To do this, keep a bucket of water near the workbench. When the blade heats up, dip it into the water. Wipe the blade before sharpening it again.

OTHER THINGS TO CONSIDER WHEN SHARPENING A LAWN MOWER BLADE

It is recommended to sharpen lawnmower blades about two times every mowing season. Or observe this simple step. If you see that the grass has a clean, smooth edge after you have mowed over it, the lawnmower blade is still sharp. But if the grass is frayed or torn, the blade is probably dull and needs sharpening.

If the lawnmower blade isn’t balanced properly, it can cause the mower to vibrate or even damage its internal parts. Balance the blade when it is removed for sharpening. One way to do this is with a blade balancer, which can be found at hardware stores or gardening centers. But even if you don’t have a blade balancer, it is still possible to balance a blade. Place the blade on a wood dowel. If one side tilts, file the opposite side of the blade. Test the balance until the blade lies flat.

If you feel that sharpening a lawnmower blade is too much, complicated, or feels unsafe, you can call a lawnmower repairman to do a professional sharpening service. He can sharpen and balance the blade at a very reasonable price.

WHEN TO REPLACE LAWN MOWER BLADE

In some cases, sharpening is not an option. If your lawnmower blade is bent, badly worn, dented, or cracked, sharpening will not be able to fix these problems. The easiest option in such a scenario would be to replace the blade. When in doubt or if you need assistance, ask the help of a lawnmower repairman.

FINAL THOUGHTS ON LAWN MOWER BLADE SHARPENING TOOL

Your Lawn Mower Blade Sharpening Tool is a very important addition to your lawn maintenance tools. When I first bought it, I didn’t quite understand how to use it properly. I had to find an expert to help me do it. You could also do the same. Finding an expert prevents premature damages. It also prevents any fatalities. It is therefore very important that you do this. In addition to that, you should also keep the user manual closer to your heart.
