How to Sharpen the Blade on Your Walk Behind Lawn Mower

How to Sharpen the Blade on Your Walk Behind Lawn Mower

Sharpen the Blade on Your Lawn Mower

A sharp lawn mower blade is crucial to keeping your lawn well-groomed. To achieve a quality cut and healthy lawn, it is important to regularly replace or sharpen the blade on your lawn mower. One sharpening at the start of the mowing season and one around the middle of the season is usually sufficient until you store your mower for the winter. However, you should periodically inspect your lawn and lawn mower to help determine if it is time to sharpen or replace your lawn mower blade. If you notice unevenness in your lawn, notice the tip of each grass blade is torn and not cleanly-sliced, or the lawn mower blade has dings, nicks or rust, then it is time to sharpen or replace your lawn mower blade.

Here’s how to sharpen the blade on your walk behind lawn mower.

Before performing any maintenance on your lawn mower, refer to your owner’s manual for maintenance instructions and safety information.

To prepare your lawn mower for maintenance, disconnect the spark plug wire from the spark plug to prevent accidental starting. Turn the mower on its side; make sure the air filter and the carburetor are facing up.

To remove the lawn mower blade, start by placing a block of wood between the blade and the frame of the mower to support the blade as you apply force. Remove the hex bolt and the blade bell support that holds the blade and blade adapter to the engine crankshaft. Take the blade and adapter off the crankshaft (cutting blades are sharp – always wear heavy duty gloves when working with blades).

Sharpen the blade with a mower blade sharpener, file, or on a grinding wheel. Do not try to sharpen the blade while it’s still on the mower.

Secure the blade in a vice when sharpening with a file or hand-held grinder. When you sharpen the blade, follow the original angle and grind. To keep the blade balanced, grind each cutting edge equally.

To test the mower blade balance, remove the blade and balance it on a round shaft screwdriver. Shave metal from the heavy side until the blade balances evenly.

Before placing the blade back on the mower, lubricate the blade adapter and crankshaft. To do so, lubricate the crankshaft and inner surface of the blade adapter with light oil and then slide the blade adapter onto the engine crankshaft.

Replace the blade adapter. The side of the blade marked Bottom, or with the part number, should face the ground when the mower is in operating position. Make sure the lawn mower blade is aligned and seated on the blade adapter flanges. Place the blade bell support on the blade.

Align the notches on the blade bell support with the holes in the blade. Replace and tighten the hex bolt by hand. Place the block of wood between the blade and the mowing deck housing again and tighten the hex bolt to the torque recommended in your owner’s manual.

Turn the mower right side up and reconnect the spark plug. Start your lawn mower and listen for noises or vibration. Adjust the blade balance if necessary.

Mulching Tips For May

Mulching-Tips-For-May - Featured Image

We are in the midst of the heaviest growing season of the year for your lawn. There has been a decent amount of rain and the temperatures are starting to rise, making for ideal grass growing conditions. These conditions make lawns healthier and beautiful, but they can also make it difficult to keep up with mowing as it seems like your lawn needs to be cut every other day. This can be particularly challenging for those of us who mulch our grass. The heavy, thick grass can make a mulched up mess if it is not mowed properly, here are some tips to utilize mulch and deal with these difficult conditions:

Mulching Tip #1 – Mow when the grass is dry. Grass stores a lot of water naturally and even more when it is growing this quickly, so try to avoid mowing when the morning dew is on the ground or soon after rain. This can cause mulched clippings to clump up and not disperse evenly.

Mulching Tip #2 – Only cut 1 inch of the grass blade off at a time. This will keep the clippings at a size that can be easily decomposed and returned as nutrients. If the length of the lawn gets away from you, it is okay to mow 1 inch off and then take another inch off immediately after – the size of the clippings is a bigger issue than the total volume.

Mulching Tip #3 - Mow at a slightly higher height. As the weather warms up, it is recommended to keep your grass a little higher to make it less susceptible to problems from heat or lack of water.

Mulching Tip #4 – Maintain a sharp mower blade. This is a common recommendation in our articles, but it is really helpful to have a sharp mower blade to cleanly cut the lawn instead of jaggedly tear it.

Mulching Tip #5 - Remove old mulch when re-mulching. If you’re considering re-mulching beds or other areas, remove some of the old mulch first. Some may mulch three to four times, so it’s recommended to remove some of the mulch that has built up over time.

Mulching Tip #6 - Try organic mulch. Organic mulches include leaves, wood chips, softwood bark, hardwood, and pine needles. These mulches provide nutrients, and improve soil structure and quality.

Mulching Tip #7 – Don’t forget your trees. Place an even layer of mulch around the trunk of your trees. This will cover the soil around the trees’ roots, improve the soil as it decays, discourage foot traffic and power tools. Make sure you spread mulch evenly without piling it against the bark, which can lead to rot and disease.

These tips will help you with mulching throughout the spring and summer. Mulching is tremendously beneficial to the health of your lawn and can be done all season long.

Blade Maintenance

When accessing the under side of the mower deck for cleaning or inspection, always try to turn the mower so that the air filter is up.  This will keep the engine oil from draining into the air filter and carburetor area. If this happens the engine may not start. Scrape out the old grass with a putty knife or screw driver. Remove the blade and inspect it for damage, and replace it if it is bent or has large knicks in it. I recommend that you have your mower blade professionally sharpened and balanced at least once a year.

Commercial cutters sharpen their blades once a week with a professional blade grinder to ensure a healthy lawn. A dull blade tears the grass rather then cutting it; this can make your lawn more susceptible to disease. If the tips of the grass blades are brown, this is an indication of a dull mower blade. Always try to cut no more than one-third of the grass blade at once. Also, try keeping the grass on the longer side–typically 3 to 3.5 inches high. Longer grass grows slower than shorter grass.  By keeping the grass length on the long side, you can save up to 20 percent of the mowing you do annually, which could add up to 8 hours each year for an average yard. Most weeds won’t germinate in longer grass, which will help you save money on herbicides. A sharp mower blade will promote a healthy lawn and increase performance in your lawnmower, causing lower fuel consumption.
