Understanding the Importance of Blade Maintenance on Lawnmowers
A well-maintained lawnmower is essential in keeping your lawn looking its best. Routine maintenance should include checking the blades for wear and tear. According to lawnmower manufacturers, blades should be replaced once a year, but this can vary depending on usage and the type of grass you have in your lawn.
Factors Affecting Blade Longevity
The lifespan of lawnmower blades is determined by a variety of factors. Firstly, the type of grass you’re cutting can play a role. Tougher grass varieties like Bermuda and Zoysia can dull blades more quickly than other grasses. Additionally, the frequency of mowing also impacts blade longevity. The more frequently you mow, the quicker the blades will wear out. Finally, rocks, tree roots, and other debris can cause significant damage to a lawnmower blade, causing it to need to be replaced.
Signs It’s Time to Replace Your Blade
If you notice your lawnmower is leaving your lawn with an uneven or ragged appearance, it’s a sign that the blades may be dull or damaged. Another telltale sign of a dull blade is that it pulls rather than cuts the grass. Hearing unusual or strange noises coming from your lawnmower can also indicate a dull blade. If you notice any of these symptoms, it’s time to inspect your blades for damage or replace them entirely.
How to Replace a Lawnmower Blade
If your lawnmower blades are showing signs of wear and tear or damage and need replacing, it’s a relatively straightforward process. Start by donning protective gloves and goggles. Move the lawnmower onto a flat surface, remove the spark plug, and wedge the blade into place with a wooden block. Unscrew the bolt that holds the blade in place, and then remove it. Replace with the new blade, reinsert the bolt, and tighten using a torque wrench.
Final Thoughts: Take Care of Your Lawnmower Blades
The frequency with which you should replace your lawnmower blades varies depending on usage and the type of grass in your lawn. However, routine inspections and maintenance can ensure that your blades remain in good condition. Regularly sharpening blades can also prolong their lifespan. Taking good care of your lawnmower blades will result in a healthier, greener lawn year in, year out.
