Get Your Lawn Mower Ready

The first step is to get your lawn mower ready. Mostly, that means making sure its not connected to any power sources, and that its in an area where you can easily turn it on its side and reach the blade underneath.

I recommend moving your lawn mower onto a tarp or a sheet to help make cleanup easier if there are any grass clippings stuck underneath the lawn mower.

If you have a battery-powered lawn mower, now is the time to disconnect the battery. If its a cord-powered lawn mower, unplug the power cord. For gas-powered lawn mowers you should remove the spark plug.

What If You Dont Sharpen Lawn Mower Blades

Some lawn owners consider sharpening the lawn mower blades just a fuss. Why do you need to bustle and hustle if your dull blade still can cut the grass?

So, is it really okay to skip sharpening the mower blades?

The answer is yes, but not for caring lawn owners. Mowing with dull blades is still possible, but poor-quality. The worn lawn mower blades leave the torn tips of some grass clippings, and that is inevitable. As a result, your lawn grass quickly turns brown and poor. Moreover, it is much tended to be vulnerable to plant disease and lawn pests.

When you mow the grass with sharp blades, it is much easier to cut the grass fast and evenly. Proper mowing is key to a healthy lawn, thats why you should sharpen your lawnmower blade regularly. Do it especially before the start of each mowing season to keep the lawn in the best condition.

Clean The Lawn Mower Undercarriage

Once the blade is locked in place, you should take this opportunity to clean out the bottom of your lawn mower. Clean lawn mowers are more effective, tend to be able to move faster, and put less stress on the lawn mowers motor.

A shop rag and simply cleaning solution is all you should need. Scoop out any remaining grass clippings, mulched leaves, and twigs, and then gently clean the bottom of the lawn mower around the blade.

If you use any water during this process, make sure the undercarriage of your lawn mower is completely dry when you stop. If you leave the metal wet, its more likely to rust and corrode over time.

Should Both Sides Of The Lawnmower Blades Be Sharpened

The response is never exactly like scissors, a side of the mower blades should be sharp, while the opposite should be dull. One side of the lawnmower blade should be sharpened at a 45-degree angle, while the opposite side should be kept rough save for flattening any edges that are uneven. If both surfaces of the blades are sharpened, the edges will become needlessly dull far more quickly.

Blade Balancing And Reinstalling

Once you have sharpened both the cutting edges of the blade, the next step is to balance it. When you sharpen the blade, there are chances that more metal is removed from one end as compared to the other, and you get an unbalanced mower blade. Using such an unbalanced blade for mowing can result in excessive wobbling, thus damaging the motor and putting unwanted pressure on the mower.

There is a great way to check if a mower blade is balanced. Slip the center hole of the blade over a nail on a wall. Keep the blade in the horizontal position and see if it remains level. If one end rotates down towards vertical, you can determine that it is unbalanced. In this case, you can consider sharpening the heavier side to remove extra metal and retest it to get a balanced blade.

Though this nail technique works and is a simple method, you can use a mower blade balancer for more accurate results. It is a cone-shaped, multi-tiered metal fixture that can be placed on a flat surface with a blade set on the top. This tool works with a blade with a varying diameter of center holes. When you use a balanced blade, it remains level otherwise, it tilts towards either side, indicating the heavier side of the blade that needs more sharpening.

Being on top of the state of the blades is important if you care about the good maintenance of your lawn mower. Ive gathered below some extra tips related to this topic that I think can be useful.

  • Regularly check on your blades. Failure to check whether or not your blades are sharp could cause you more stress than necessary. By regularly examining the blades, you can sharpen them as soon as they become dull.

How To Sharpen Lawn Mower Blades Without Removing Them

Lawnmowers are one of the most used garden tools, but they need to be sharp to give a stunning look to your lawn. On average, lawnmower blades should be sharpened twice a year, depending upon the usage. For some owners, that may seem unnecessary as even with dull blades, theyll still cut your grass. But the point is that with worn blades, the cut will be rough, leaving behind torn tips on the individual grass blades ends. Those can cause the grass to turn brown quicker, and it can also leave your lawn more susceptible to pests and disease. This is not something that lawn owners want. Sharp blades also allow you to cut the grass evenly and quickly, thereby giving you a perfectly trimmed lawn. So, always sharpen your lawnmower blade before the start of the yearly mowing season to get the lawn of your dreams.

    How To Adjust Your Reel Mower Blades

    To move the cutters closer to the bar so your lawn mower makes that cool “click, click, click” sound reminiscent of an episode of Leave it to Beaver, you just have to tighten the blade tightening bolts on either side of the lawn mower.

    • Your mower’s blades should come as close to the metal bar as possible without actually touching it. Spin the blades . If you can hear metal scraping they need to be loosened on that end.
    • Only turn the bolt a tiny bit to get some clearance.
    • There are 4 bolts. 2 that are visible on either side of the reel and 2 on either side of the cutting bar.
    • First adjust the bolts on the reel. Then adjust the bolts on the cutting bar, turning them in the opposite direction that you turned the bolts on the reel.

    Easy. Your blades should now be evenly spaced across the whole cutting bar, almost touching it, but not quite.

    But sharpening the actual blades is something else entirely. And without sharp blades on your lawnmower, you might as well try cutting your lawn with a sock puppet. You’ll get the same results.

    My lawn would no longer look like a 1980’s haircut.
