Understanding Lawn Mower Blades

Lawn mower blades are an essential part of the lawn mower’s cutting system, which, when dull, can cause uneven and ragged cuts on the grass. Sharpening them regularly can save the time and money required to replace them. Here we explain the different blades available in the market, their anatomy, and common signs of dullness.

Different Types Of Blades Available In The Market

There are several types of blades available in the market, but the three most common types of blades are:

  • Mulching blades: They have a curved surface and multiple cutting edges that continue to chop cut grass until it is small enough to return to the lawn as a natural fertilizer.
  • High lift blades: They are known for their raw cutting and sucking power and are mostly used to tackle taller grass because they have a significant space between the blades and the mower deck.
  • Low lift blades: Compared to high lift blades, they have smaller spaces but still provide high suction power and are suitable for regular cutting.

The Anatomy Of Lawn Mower Blades

For better understanding of how blades work, it’s essential to know their anatomy.

  • The flute: It’s the raised section behind the blade’s cutting edge that generates airflow and propulsion needed to mow the grass.
  • The cutting edge: The sharp end that does the actual cutting
  • The lift: The curve of the blade that creates a lift, which forces the air to circulate underneath the deck.
  • The deck connection: The part connecting the blade to the deck: this varies depending on the lawn mower make and model.

Common Signs Of Dull Blades

Before jumping into the process of sharpening blades, it’s essential to identify some common signs of dull blades. Dull blades don’t give a clean cut because they tend to rip or tear the grass rather than cutting it. Here are some common signs of dull blades.

  • Ragged grass blades with frayed edges.
  • Brown tips or yellowing grass due to blade tearing instead of clean cuts.
  • Uneven grass height after mowing.
  • Reduced engine performance and higher fuel usage.

Preparing The Lawn Mower

When it comes to lawn maintenance, one of the essential tools you need is a lawn mower. The machine is responsible for keeping your yard looking neat and tidy. Like any other tool, lawn mowers require maintenance and care to ensure a proper and long-lasting performance.

One of the maintenance routines required for your lawn mower is sharpening the blades. In this section, we will discuss how to sharpen lawn mower blades without removing them, beginning with preparing the lawn mower.

Safety Precautions To Take

Before we discuss how to sharpen lawn mower blades, it’s essential to take safety precautions to avoid harming yourself or damaging the machine.

  • Disconnect the spark plug wire from the mower.
  • Wear heavy gloves to prevent your hands from getting cut by the blades.
  • Wear protective goggles and close-toed shoes to protect your eyes and feet from flying debris.
  • Position the mower on a level surface to avoid it from moving as you sharpen the blade.

Tools Required For Sharpening

Sharpening lawn mower blades can be done using a few basic tools.

  • A sharpening file or a grinding stone to sharpen the blade’s edges.
  • A pair of work gloves to protect your hands while holding the blade.
  • A metal file to take out any nicks or dents on the edge of the blade.
  • A socket wrench or pliers to loosen the bolt holding the blade.

Checking The Blade Before Starting

It’s essential to check the blade before sharpening it to ensure that it’s in good shape and repair any cracks or damages.

  • Check for any cracks, chips, or dents along the cutting edge and around the center hole.
  • If you notice any damages, replace the blade with a new one instead of trying to file or repair it.
  • Balance the blade before reinstalling it back into the lawn mower. The blade must be evenly balanced to prevent damaging the machine and ensure safe operation.

Following the safety precautions, and having the right tools are critical steps to take before sharpening the lawn mower blades. Additionally, ensuring the blade is in good shape and balanced will guarantee a proper and long-lasting performance of the lawn mower.

Keeping your lawn mower blades sharp is important in maintaining the garden’s health and preventing damage to your machinery. If your lawn mower isn’t cutting grass smoothly, it’s not always necessary to remove the blades to sharpen them. Here are some simple diy methods to help you sharpen your lawn mower blades without removing them.

Step-By-Step Guide To Sharpening The Blade

  • Disconnect the spark plug – before attempting any maintenance, disconnect the spark plug to ensure the lawnmower is safe and can’t start accidentally.
  • Clean the blade – it’s important to clean the blade before sharpening it. Remove all grass, dirt, or debris using a wire brush, scraper, or compressed air can.
  • Secure the blade – tilt the lawnmower on its side with the carburetor facing upwards. Wedge a block of wood between the blade and the mower housing to hold the blade in place safely.
  • Sharpen the blade – using a metal file, file each cutting edge at the same angle it was originally sharpened. The angle of the blade may vary depending on the manufacturer’s specification. Follow this angle strictly to maintain the blade’s quality.
  • Test the blade – stop sharpening the blade when it is sharp enough to cut the paper. Ensure you test the blade once you have filed it by cutting a newspaper or paper.
  • Reconnect the spark plug – once you are sure that the blades are sharp enough to cut the grass, reattach the spark plug.

Checking The Balance Of The Blade

After sharpening, it is crucial to ensure that the blade is balanced. A balanced blade will spin without wobbling, reducing the stress on the engine and prolonging the life of your lawnmower.

  • Find a nail – insert the nail into the hole in your lawnmower blade; make sure the nail fits in perfectly.
  • Hang the blade – once the blade is on top of the nail, hang it with a spirit level.
  • Notice if the blade is balanced – if the blade is straight, stay on that side of the blade, and check the other side until it is also level.
  • Add or remove metal – to balance a blade, add or remove metal to the heavier end, make sure not to remove more than 1/3 of the total blade length.
  • Test the blade – test the blade after you have finished balancing the blades.

Keep your lawn mower blades sharp to effectively mow your garden. Use the proper tools and techniques, and follow these steps to make sure your lawn mower’s blades stay in good condition.

  • Keep the blades clean: After using the lawnmower, remove any debris or grass clippings from the blades. This will prevent corrosion and keep the blade edges sharp.
  • Sharpen the blades regularly: Sharpen the blades at least once a year to keep them in good condition. Use a file or a sharpening stone to remove any nicks or dull spots on the blades.
  • Balance the blades: Unbalanced blades can cause undue wear and tear on the lawnmower engine. To balance the blades, place a small nail in the center hole of the blade and suspend it. If one end of the blade tips downward, remove a small amount of metal from that end until it balances properly.

Maintaining sharp blades is essential for a well-maintained lawn. However, it can be challenging to sharpen blades without removing them.

  • Use a grinding stone: A grinding stone is an inexpensive tool that can be used to sharpen blades without removing them. Simply run the stone along the edge of the blade to sharpen it.
  • Use a metal file: A metal file can also be used to sharpen blades without removing them. Simply run the file along the blade’s edge, but be careful not to file the blade too aggressively as it may damage the blade.
  • Check the blade regularly: The best way to maintain blades is to check them regularly for damage or dullness. If you notice that the blades are not cutting as well as they used to, it may be time to sharpen or replace them.
