How Often Should You Replace Your Lawn Mower? 

Purchasing a lawnmower is a wise investment as it enhances the cleaning of the lawn. In addition to freedom from back fatigue,  it is cleverly built with sturdy materials to guarantee an extended lifespan. However, these machines are susceptible to depreciation and can shut down completely or lose effectiveness over time. Therefore, let’s get the right answers to the question, how often should you replace your lawn mower? 

The lifespan of a lawnmower depends on how frequently you use it. A good lawn mower offers reliability in your quest for well-cut grass in your lawn. So the moment you detect any signs of malfunctioning, you’ll know it’s time for replacement or repair. Such signs include failure to start, loss of power mid-mow, harsh vibrations from the mower, and more. 

This article aims at giving you information regarding the handling of your lawn mower. Keep reading for more insight on the subject.

How Do You Know If You Need a New Lawn Mower?

You can easily tell that you need a new lawnmower when the existing one starts misbehaving, especially after prolonged use. Don’t be tempted to repair major damages as it might cost you more. 

For instance, if your lawnmower hits a rock or a tree stump, it will stop and fail to restart. The shaft that attaches the blades to the mower’s engine might bend, which can be a very expensive repair. 

Other signs that might prompt you to purchase a new lawnmower include technical problems and normal wear and tear. You may also want a new lawnmower if your mobility needs to change or if the shape or size of your lawn changes. 

I say this because not all lawn mowers excel well on all types of lawns. As such, it’s important to settle on the right option that corroborates your needs. 

What’s more? If your lawnmower suffers minor damage, consider repairing it. However, if that isn’t a viable option or if the repair cost is not less cost-effective, purchase a new one. 

Also, if you see any of the below issues, don’t hesitate to acquire a new lawnmower: 

  • Transmission Issues

Often, transmission is an exorbitant repair. Usually, it costs about $500 to replace. So if you want to keep your lawn’s aesthetic appeal, don’t pay over the odds by opting for the expensive route like costly repairs. 

  • Engine Problems

Engine failure costs more to repair than replacing it. So it’s important to know that a blown engine is normally a death sentence for a lawnmower. 

  • Not Under Warranty

Without a lifetime warranty, lawnmowers are very pricey to repair. Ideally, a good lawn mower will serve you for 7 to 10 years; however, repairs come up. Things like broken cables or belt pull cords are cheap to replace. However, mechanical issues are more costly. 

Therefore, if your lawnmower malfunctions, examine its warranty to discover if it’s covered. 

  • Upgrade

You’ll inevitably need to upgrade your lawnmower to enjoy easier mowing. New models will grace you with lasting benefits, including fuel efficiency, saving you money over time. 

How Often Should Lawn Mower Blades be Replaced?

Ideally, you need to replace your mower blades annually. This is because dull mower blades shred grass, which turns ugly and becomes susceptible to disease. By contrast, sharp blades trim grass evenly, offering your yard a smooth and healthy look. 

After visually inspecting your mower blades, you will easily tell if your mower blades have any dents and nicks. Blade erosion occurs with time due to yard debris. 

Therefore, ensure you inspect your blade’s thickness and sharpen them regularly to extend the lifespan if replacing isn’t your priority. However, be careful when sharpening the blades to avoid common injuries. It’s even better to wear protective gloves and disconnect the spark plugs before sharpening the mower blades. 

Besides, people also ask how long do lawnmower blades last? A typical lawnmower blade can survive up to 100 to 200 hours of use under normal conditions. This number of hours can extend to 400 if you opt for high-quality blades. 


Maintaining your lawnmower blades guarantees a healthy and neat yard. It’s therefore integral to examine your mower blades after use to ensure it’s damage-free and sharper. 

Regular inspection of these blades also guarantees the proper growth of grass. So the moment you notice your blades are chipped or dull, sharpen them immediately. 

If the damage is beyond repair, consider replacing them as sharpening will inflict more harm than good. Replacing the blades prevents them from breaking during use. 

  • Uneven Length of Grass

You can easily tell that your mower blade is blunt when the final cut doesn’t appear great as usual. You will notice uneven patches or mow your lawn several times before it cuts right. 

That’s because dull blades require more effort to trim your grass, plus you will have to compensate for the missed patches to yield desirable outcomes. So suppose you realize that your mower takes more time to trim grass than usual; it implies that the blades require sharpening or a total replacement. 

How to Replace Lawn Mower Blade

Lawnmower blades often degrade with time due to extended hours of use and other barriers. 

For instance, the high speed of the blades can hit an obstacle and possibly break or bend. Luckily, you can evade these constraints by replacing your ravaged mower blades with new ones and proceeding with your mowing as usual. 

The good thing is that this task is relatively straightforward, so even those who lack prior experience can do it. Follow these steps to replace your blades successfully: 

Step 1 

Safety is always a center of concern with any DIY job. So begin by wearing safety gear before touching anything. 

If your lawnmower is cordless, disconnect the battery pack. You then disengage the ignition wire from the spark plug to prevent accidental Start-up while working. You will also want to drain the gas tank then return the gas lid. Doing so prevents spills when you tilt the lawnmower. 


If using an electric lawnmower, ensure it’s not plugged in.

Step 2 

Next, position your lawnmower on a flat area with the parking brake engaged. Then tilt the mower to expose the nut that secures the blade to the mower. While tilting, you will need to be careful by ensuring the carburetor and the fuel tank face the top side to prevent leakage. After that, use a wrench and socket to unfasten the nut. 


If you are dealing with a troublesome fastener, you can increase its leverage when unfastening by placing a metal pipe over the wrench handle. You may also want to position a wooden block transversely at the lawn mower’s far side to enhance stability in the tilted position.

Step 3

Next, uninstall the nuts using a socket wrench of an appropriate size exactly when holding the blade with your other hand to keep it from turning. Then you tilt the wrench counterclockwise to unfasten and remove the but. 

You have to do this precisely and be watchful not to lose the mounting hardware that holds the blade in position. 

Step 4 

You can now install the new blade. Ensure you are equipped with your heavy-duty gloves before holding new blades. The essence of the gloves is to avoid unexpected cuts from the sharp sides of the blade.

After that, take the new blades and line them up in position carefully. Next, reinstall the nuts and washers. If you have the user’s manual, you should discover the torque specs for fastening the nuts. But if you don’t have, be sure not to over-tighten the nut considering that it might introduce vibrations in your mower. 

Also, ensure the length of the new blade is synonymous with the previous one before installing it. 

Step 5

After successfully installing the new blades, remove the props used to hold the lawnmower in place, then lower it carefully. Give the mower time to settle for about 30 to 60 minutes. This way, the oil will return to the motor, preventing unexpected motor damage. 

Step 6

For gas mowers, refill the gas tank and re-engage the spark plug wire. Then conduct a quick inspection before mowing. Confirm that the air filter is not saturated with oil. After inspection, you’ll have finished your replacement procedure. 

Your mower should now cut grass more efficiently, leaving a well-manicured appearance.  

Precautions and Safety

  • Before installing the blades, ensure that they don’t nullify your lawn mower’s warranty. 
  • Ensure the carburetor faces up when tilting the mower. 
  • Wear heavy-duty gloves. Even though this step is often disregarded, it’s integral to wear gloves to avoid unwanted injuries. 

How Often Should You Maintain Your Lawn Mower?

Keeping your lawnmower in good working condition helps maintain a beautiful and healthy lawn. It’s also handy in guaranteeing an extended lifespan. 

You can maintain your lawnmower yourself or hire a service expert to handle it professionally. Either way, how often should you maintain your lawnmower? 

Maintaining a lawnmower should be done once a year, and it only consumes a few hours to complete. The best time to maintain your lawnmower is at the beginning of the season before the first mow and the end of the season when you’re storing your lawnmower until the next season.

Here is a checklist of annual lawn mower maintenance. Use it to ensure your lawnmower keeps running at its best. 

  • Change oil.
  • Fog the engine to prevent the lubricants from draining away over time, causing damage and corrosion. However, never pour water directly into the engine and avoid using a pressure washer to clean your mower. 
  • Adjust the mower blades.
  • Clean the lawnmower to prevent the decaying grass from eating all the metal components. 
  • Replace and clean the air filter, so your lawnmower works at peak efficiency. 
  • Replace the spark plug to ensure the lawnmower starts up easily. Also, uninstalling the spark plug before beginning maintenance is wise as it prevents accidental start-up. 
  • Sharpen the mower blades for smoother and even cuts. 
  • If you’re discontinuing your mower for more than 30 days, drain out all fuel from the mower. 

How Long Do Lawn Mowers Last?

With proper care and maintenance, a lawnmower can endure 7 to 10 years of use. However, if you disregard maintenance practices, expect your mower to last less than five years. Here are the most emphasized practices that can increase your lawn mower’s lifespan. 

  • Quality

It is recommended that you purchase high-quality and durable mowers for your machine to survive years of maximum ill use. Doing this means you’ll never spend money on a new lawnmower.

Even if they are slightly expensive, they’ll go over patches of grass easily, unlike cheaper mowers that malfunction prematurely. 

  • Change oil

You need to change oil annually, so your engine runs exceptionally well. You can confer with the user manual to know the regular maintenance schedule. As you change the oil, ensure the fuel tank is empty. This prevents spilling when you alter the lawn mower’s position.

Why Do Commercial Mowers Cut Better?

Commercial mowers cut grass better than other prevalent options because they integrate quality components. They also brag higher blade speeds than the residential mowers, reducing clumping significantly.

Another reason commercial mowers cut better concerns the engines. They have large and powerful engines that can overcome any obstacle without exhibiting any issues.

How Much Does a Lawn Mower Service Cost

The cost of mending a lawnmower usually depends on the type of mower you have and the complexity of the repair. Generally, repair costs range from $40 to $90 per hour. Other repair costs narrow down to the price of the supplies needed to repair the mower.

The repairs for smaller mowers are less expensive compared to large mowers like the riding mowers. How your lawnmower is powered: by electricity or gas is also a key factor in the cost. 

Is It Okay to Hose Down a Lawn Mower?

Yes, it’s advisable to hose off your lawnmower, but don’t splash water directly to the engine considering the mower is not waterproof. Spraying water on the electrics causes malfunctioning, which is relatively expensive to repair, and the warranty won’t cover it. So it’s wise to avoid the transmission, cables, and belts. 

Use this trajectory to hose down your lawnmower without damaging the engine. 

  • Disengage the grass bag. 
  • Lower the deck height.
  • Attach the hose to the deck.
  • Turn on the water. 
  • Start the mower. 
  • Run the blade until water runs clear.
  • Remove the hose water. 
  • Ignite the mower and run the blade to dry the deck.

What Is the Best Time of the Year to Buy a Riding Lawn Mower?

Most seasonal products are cheapest when demand is at a minimum, and riding lawn mowers are no exception. So the best time of the year to invest in a riding lawnmower is in August or September and early fall when the busy summer mowing season is depleted. 

Ideally, each season has different factors to consider when purchasing a new riding lawnmower. Immediately after the summer months, you’ll likely enjoy a good deal as sellers strive to sell their last models. Also, new lawnmowers are being discounted before the peak season. 

Therefore, to recap on the best time to acquire a lawnmower, it’s best to wait for the end of the season. This way, you won’t spend over the odds to own a new riding lawnmower. 

Is It Bad to Pull a Lawn Mower Backwards?

No, it’s not bad to pull a lawnmower backward, but you should not practice mowing in reverse due to safety reasons. Pulling a lawnmower backward is handy in maneuvering through tight crevices and around landscaping. 

Thanks to the upgrades in lawn mower manufacturing, we now have mowers with reverse features that allow the blades to run in reverse. The reverse feature is manual, meaning you need to have prior experience to use them. 

But once you capture the technique, you will enjoy operating your mower in reverse exactly when keeping the blade and motor operational. 

  • Riding Lawn Mowers

Today’s riding lawn mowers models encompass a reverse implement operation function that keeps the mower engaged while backing up. Given that it is a manual feature, you should allow your mower to stop before clutching the button. 

So when your mower stops, hold down the RIO button in the reverse position, then push the shift lever into reverse. If you’re working with an automatic drive mower, engage the reverse foot pedal. 

You can release the button and run your mower while backing up and forward operation at this juncture. You don’t have to press the RIO button twice.

Disadvantages of Pulling a Lawnmower Backward

  • Reduced Performance

Regardless of the convenience, lawnmowers don’t perform well in the reverse mode because of many factors. For instance, your mower won’t discharge grass clippings properly when backing up because the direction is contrary to the machine’s design. 

Secondly, you will achieve irregular cuts because operating backward means the blades are running in reverse. As such, your grass will appear choppy and uneven in the areas you trim with reverse. 

  • Safety Issues 

When trimming your lawn in reverse, your visibility is restricted. Additionally, dragging a non-riding lawn mower backward presents a risk to your feet. 

Even if your mower incorporates a protective flap, there are chances your feet will stumble and get entangled in the mower blades. So generally, the risk of pulling a lawnmower backward outweighs the conveniences. 

Is It Okay to Push a Self-propelled Mower? 

Yes, it’s advisable to push a self-propelled lawnmower as it won’t harm the transmission. The only downside is it’s uneasy about doing so, given that self-propelled mowers are slightly heavier than the topical push mowers. 

Why Does My Mower Leave a Strip of Grass in the Middle? 

Using a lawnmower alleviates the process of manicuring a lawn. However, mowing problems still materialize from time to time. Among the common problems include a row of uncut grass, irregular cutting, and more. Usually, the problem results from mowing with dull blades, operator error, speed issues, etc. 

  • Dull or damaged blades

Strips of grass in the middle of your lawn imply that your lawn mower’s blades are dull or damaged. Usually, dull blades are caused by normal wear and tear from mowing, but you can sharpen them with a grinder and resume trimming your lawn. 

  • Other blade issues

Apart from damaged and dull blades, a strip of uncut grass between the mowing rows signifies that your lawn mower’s blades are unbalanced or installed inappropriately. A mower’s blades are beveled and conspired to attach in a particular fashion.

If one of them is upside down, you’ll achieve shoddy mowing. Ensure your mower blades are aligned correctly and secured tightly to the deck. 

  • Overlap mistakes

Another reason for uncut grass between mowing rows is the failure to overlap the rows enough. You need to overlap each row by a few inches so the blade suction pulls up the grass. 

  • Speed issues

Streaky or patchy uncut grass may result from mowing too fast, so slowing down while trimming prevents that from materializing. 

Which Is Better, Front or Rear Wheel Drive on a Lawn Mower?

If you plan to make trimming your lawn easier, you will need to liberate yourself from your outmoded push-on mower and choose a self-propelled mower. This type of mower utilizes a set of drive wheels: either front or rear, to propel the lawnmower forward. 

Both the front and rear wheel propulsion mowers deliver unique benefits. However, the question is which one is better? 

Ideally, the rear-wheel-drive mower is a better pick over front-wheel drive. That’s because it offers better traction in complex terrains with steep inclines, hills, and valleys at the expense of maneuverability. It also boasts strong wheels that propel the mower ahead regardless of the impediments.

Even though rear-wheel drive mowers don’t offer the maneuverability of front-wheel, they are ideal for larger and wide-open spaces. The other downside of a rear-wheel-drive mower is it’s uneasy to drag the mower backward to change direction. That’s because the wheels are usually engaged in the forward movement.  

On the other hand, front-wheel drive mowers are also handy on flat terrains, and they permit you to steer the mower around lawn ornaments, trees, shrubs, etc. 

Why Does My Mower Cut Better When I Pull it Backwards? 

Your lawnmower may function better in reverse gear than forwarding gear due to many reasons. For instance, pulling the mower backward enables the blades to cut from both sides for a pleasing appearance. 

Reverse mowing also allows the blades to access the confined spots left out in the first pass, which adds to the convenience of enhancing fine cuts.

Should You Change the Direction You Mow Your Lawn? 

Yes, it’s wise to change your mowing direction. Doing so helps your blades to remain straighter and healthier for an extended time. Grass blades often grow in the direction they are mowed. So alternating the pattern returns the blade to an upright position. This also guarantees that you won’t develop ruts in your yard from the mower wheels. 

What Are the Common Mowing Precautions? 

Mowing your lawn seems a straightforward task, but you need to adhere to some specs for you to reap your desired outcomes. Check out below:

  • Avoid mowing too low. 
  • Avoid cutting wet grass. That’s because your blades will stick together, resulting in irregular cuts. 
  • Avoid rushing to mow even if you have a busy schedule. Quick mowing leaves uneven clumps of clippings on the yard, giving it an unsightly look. 
  • Always mulch your grass as you mow, so the soil retains its moisture.  

What Is the Purpose of a Trailing Shield on a Lawn Mower? 

A lawn mower’s trail shield is positioned at the back of the mower, and it staves off debris from flying towards the operator. Ensure it’s working as expected before the beginning of the mowing season. 

Final Thoughts 

As spoken of earlier, a lawn mower is a must-have piece of equipment on your top-wish list. It comes with contemporary features to propel peak performance plus its cleverly built body maximizes the lifespan. However, frequent usage makes this elegant machine lessen its reliability and lifespan. As such, you’ll want to know…

How Often Should You Replace Your Lawn Mower? 

You need to replace your lawnmower depending on the frequency of use and damage. However, if the damage is not severe, consider repairing the mower to avoid adding to the cost.
