Mowers with dull blades have to work harder to cut the grass, which leads to missed patches and uneven lawns. You will not only have an uneven lawn, but you will also have to spend more time mowing it. The damage caused by this can eventually require you to reseed your lawn. Making your mower more efficient and keeping your lawn looking great is as simple as changing your blades.
The blades of your lawn mower can cut sharp and faster from approximately 90 hours to 210 hours. This value of the longevity of the lawn mower blades goes up as high as 450 hours if you use lawn mower blades manufactured from premium and fine grade materials. When a rock, boulder, or other firm object chips or dent the blade, it must be changed.
Regularly changing the lawn mower blade will help ensure that the blade remains sharp and effective at cutting grass. Below will talk about the different types of blades and how to tell if it’s time for a new blade. Read “How Often Change Lawn Mower Blade?” to learn more.
The frequency of changing a lawn mower blade depends on several factors, including the type of terrain and grass, frequency of use, condition of mower blades, and quality of mower blades. Each factor has a direct impact on how often a blade needs to be changed.
Mowing the lawn is an integral part of keeping it in shape, but if you’re not using the right tools for the job, you won’t get the best results. That’s why it’s essential to pay attention to how often you should be changing your mower blade.
Factors that Determine How Often to Change the Blade
Different types of grass grow at different rates and require different amounts of trimming throughout the season. If your lawn is comprised chiefly of cool season grasses, such as Kentucky bluegrass or fescue, you may need to change your mower blades more frequently than warm season grass varieties like Bermuda or St Augustine.
It’s essential to consider the terrain when deciding how often to change your mower blade since soft or uneven surfaces can cause more damage on blades than flat ones do.
Another factor that determines when it’s time to change your lawn mower blades is the thickness and length of your grass being cut each time around the yard.
If your grass is thicker or longer than normal then this will put extra strain on your blades each pass that they make across it, leading them to dull faster than usual and necessitating more frequent replacements for them to remain at peak performance levels for optimal cutting results each time around the yard.
How much you use your lawn mower also affects how frequently you should change its blade. If you only use your mower a couple of times a year for quick touch ups, then changing its blade every 30 to 45 days may be sufficient.
If you regularly cut large swaths of grass at least once a week during peak growing season, then changing its blade every 7 to 10 days is recommended for optimal results.
Even if the amount and type of grass remain consistent and usage remains regular, other factors can lead to the deterioration of lawn mower blades over time, such as loose nuts & bolts or worn out parts that can cause extra friction when cutting through blades, making them dull faster than expected.
This is why it’s important to inspect any parts before each use and ensure they are tightened up properly so they don’t contribute further damage to already worn out blades.
It is also essential to consider the lawn mower blade material quality when buying new blades for changing since inferior quality materials will likely not last as long as those made from higher grade steel alloys. If possible, opt for those made with commercial grade steel.
Although these lawn mower blades come with a slightly higher price tag upfront, they will ultimately save you money over time due to their superior longevity compared with cheaper alternatives.
These are just some factors that determine how often one needs to change their lawnmower blades but knowing how frequently one should change their lawn mower blades isn’t enough.
When it comes time to change lawn mower blades, ensure not to throw them away carelessly but recycle them at designated drop off sites in compliance with local regulations where available.
Recommended Guidelines for Changing the Blade
When changing your lawn mower blade according to recommended guidelines, there are general rules based on the frequency of use. Lightly used lawns should have their blades changed every 30 to 45 days; average used lawns should be changed every 15 to 20 days.
Heavily used lawn mower blades should be changed every 7 to 10 days. But these can vary depending on individual factors such as the type of grass and terrain discussed above and personal preference regarding when one might like their blades changed for optimal results each time they use their equipment.
Other Considerations for Changing the Blade
Time investment is another consideration when changing out a lawn mower blade, as this task will take some dedicated time from the beginning (safety measures) through completion (testing that new/properly installed parts work).
Proper safety measures must be taken before performing any work on a machine. Disconnect power sources from your gasoline or electric lawn mower before making any changes or adjustments.
So that there is no risk involved with the lawn mower blade changing operation until those parts have been tested after installation adjustment is complete. This will help ensure everyone’s safety while enjoying outdoor activities such as yardwork or lawn care & maintenance, etc.
For High Quality Blades
1. It is essential to follow the manufacturer’s instructions when changing the lawn mower blade, as they will be better able to instruct on how often it needs changing based on the specific model and its usage frequency.
Generally, it is recommended that high quality blades are changed once every season or year if the lawn mower is used regularly. This helps keep the blades sharp and ensures that your lawn is always cut with optimal precision.
If you only use your lawn mower occasionally, then it is advised to change your blade every two to three seasons to maintain a beautiful lawn.
2. Regularly inspecting the blade for any signs of deterioration is also essential to ensure that you use a sharp, effective blade. This includes looking for any chipping, cracking, or dents in the blade’s surface.
This can cause an uneven cut and produce an unsatisfactory result. If these issues are detected, then it will be necessary to change the blade as soon as possible to avoid further damage being caused by the continued use of a dull blade.
For Low Quality Blades
1. Low quality blades should be changed at least once or twice a year if not used regularly. This helps maintain their effectiveness and prevents uneven cutting due to a dulled edge over time.
You should change your blade every six to eight weeks if you only use your lawn mower occasionally to get consistent results.
Low quality blades should also be inspected regularly so any signs of breakdown can be detected right away.
2. When you buy new blades for your machine, be careful not to pick one that’s too heavy. It might strain your motor and eventually cause mechanical problems over time.
A good quality lubricant should also be used when changing low cost blades as this will reduce friction between parts and extend their lifespan.
Changing the lawn mower blade frequently can provide a number of performance benefits.
- Firstly, it will ensure that your lawn mower produces cleaner, even cuts. With a fresh blade, you won’t have to worry about frayed or uneven grass, and you won’t need to go back over large portions of grass multiple times to get even results.
- Regularly sharpening and changing blades puts less stress on the engine due to reduced cutting resistance. The grass is cut with greater efficiency as more power is put into cutting the grass rather than fighting against an old, dull blade.
- Finally, a sharpened blade will produce cleaner cuts which ultimately leads to quicker and easier mowing sessions allowing you to spend more time enjoying your garden.
Reduced Maintenance Costs
Changing the lawn mower blade regularly also reduces maintenance costs significantly in several ways.
- Firstly, when blades are kept sharp, they are less likely to suffer from deterioration, reducing the need for repairs.
- Secondly, if blades become too dull, they can cause damage to other parts of the mower, such as the engine or transmission, which can be expensive to repair or change. Keeping blades sharp can also reduce the risk of injury as you are less likely to be injured by a sharp blade than one that has become blunt over time.
- More durable blades which are kept in reasonable condition last longer, meaning that there is less need for replacement blades saving money in the long run.
Preparation Before Changing the Blade
Before attempting to change a lawn mower blade, it is essential to take safety precautions. This includes shutting off or unplugging the motor, as well as wearing protective gear such as safety glasses and gloves.
It is wise to raise the mower’s deck up to gain access to the blades underneath. When doing so, make sure that you tilt the motor away from you to avoid any kickback of dirt particles.
Removing Old Mower Blades
Once your space is prepped for the job, begin by releasing any retaining nuts or bolts holding the existing blade in place. Once these are removed, gently pull out the old blade and set it aside for disposal. Take some time to clean off any trash particles from around the mounting area before installing a new blade.
Installing New Mower Blades
When selecting a replacement blade, look for one that matches your mower model and size specifications. Align this new blade with the mounting area on your machine and secure it with its retaining nuts or bolts. Make sure everything is firmly put together before taking further steps in the installation.
Finalizing Installation Process
Now, it’s time to wrap things up! Start by lowering the deck back into place on top of your newly installed blades so everything is flush and level once again.
Check overall performance while running through a few tests just to be sure everything is working correctly and safely before giving it a try in an open area, cleaning up any mess created during installation along the way.
It is essential to regularly sharpen your old lawn mower blades for the following reasons:
- To save time: dull blades can cause long grass to be cut unevenly, resulting in more time spent on trimming and edging, which can be avoided with sharpened blades.
- To save energy: dull blades make it harder for the engine of your mower to power through tall grass, resulting in higher fuel consumption and increased strain on the engine.
- To prevent damage: blunt blades can tear through the grass instead of cutting it neatly, which can cause damage to delicate plants or create bald patches in your lawn.
- To have a beautiful lawn: sharp blades leave a neat edge on each cut which ensures that every piece of grass is evenly shaped, creating a uniform look across your entire lawn.
It is hoped that this “how often change lawn mower blade?” guide has provided some helpful insight into understanding when exactly it is necessary to change and sharpen your lawnmower blades so that you can get back outside enjoying those perfect summer days.
Keeping up with regular maintenance, like changing out or sharpening your lawnmower blades, ensures that your mower runs efficiently while producing clean cuts that keep your yard looking its best all year round.
