Lawn mower blades are crucial. Over time, they dull with use. You’ll need to sharpen or replace them eventually. Sharpening blades extends their lifespan and saves money.
However, using a dull, broken, damaged, or missing patch mower blade can lead to several easily identifiable issues.
Using dull or damaged lawnmower blades causes significant vibration. This vibration harms the grass roots, which is easily visible.
If you spot these signs, it’s time for new wiper blades.
How Often Should I Change My Lawn Mower Blade?
This is a frequently asked question. We encounter it very often.
FyPower specialists now advise replacing your mower blades every year. For lawn care professionals, frequent blade changes are essential after extensive use.
However, the overall efficiency hinges on its grass-cutting capabilities.
How To Change Lawn Mower Blade?
Good news! Replacing your mower blades is a breeze with our updated, easy-to-follow guide. With the correct tools, you can complete this task in under 30 minutes.
We’ve simplified the process into two straightforward steps.
How To Remove The Old Blade
Unplug The Spark Plug
To prevent accidental engine starts, we strongly advise you to remove the mower’s spark plug first. This is a crucial safety step. It prevents electrical sparks if oil or gas contacts the plug. While proper mower positioning minimizes risk, this precaution ensures maximum safety.
Lift The Mower Deck To Expose The Blade
Inspect the mower carburetor and engine thoroughly before raising the mower deck. Avoid lifting the mower by the carburetor or engine side. To prevent spills, drain the oil or gas from the carburetor before tilting the machine.
If you can’t remove the oil or gas, ensure the tank is secure. Prevent any leaks.
Employ a hedge as a support. Gently raise the mower’s side. This provides easy access to the blades underneath.
If you’re still unsure, we strongly advise consulting your mower’s manual. It contains essential information.
Remove The Blade Mounting Bolt
Wear durable work gloves. Use the correct size socket wrench to loosen the mounting bolts. Hold the blade firmly to prevent it from rotating while you unbolt it.
Important: Keep all hardware like washers and bolts safe when removing the mounting bolt. You’ll need them again.
Carefully observe the blade’s position as you remove it. This ensures the new blade is installed with the correct orientation for optimal cutting. Typically, the blade’s sharp edge rotates counter-clockwise with the assembly. However, this might vary across different mower models. Therefore, closely examine the existing blade’s placement before removal and replicate it when installing the new one.
But why, though?
Ensure the new blades are installed facing the same direction. This guarantees optimal cutting performance.
Installing New Blade
Purchase Replacement Blade
Buying a new blade from where you got your mower is smart. Online or in-store, a push mower blade replacement kit is cheap. It includes new, sharpened blades and nuts.
Older lawnmowers often feature a bottom cap design. This includes two smaller, distinct blades attached beneath.
Modern mowers now use a single, extended blade resembling a ruler for cutting grass.
Carefully tilt your mower back to examine the blades. Alternatively, consult a hardware store expert for blade recommendations specific to your mower. You can also find this information in your mower’s manual.
Important: Consider sharpening your existing baler blades if they’re in good shape. This can be a cost-effective alternative to replacement.
Replace chipped or damaged blades immediately. New blades ensure optimal performance and safety.
Mounting The New Blades
Install the new blade, ensuring it faces the correct direction. Use the original or new washer and nuts, matching the correct size. Align the replacement blade precisely. Refer to your mower’s manual or the manufacturer’s website for torque specifications to properly tighten the nuts. Avoid over-tightening, as this can lead to excessive mower vibration.
Precautions
Check The Blade For Play
Confirm the mower blade is correctly positioned. Before starting, check for wobbling during height adjustments. Ensure it’s securely fastened to the engine drive shaft.
Refill The Gas Tank And Do A Pre-check Before Mowing.
Ensure your mower is ready! Top off the gas or oil. Then, give it 30-60 minutes for proper fuel circulation before you begin mowing.
Inspect your mower’s air filter. Ensure it’s free from dust and clogs. If it’s dirty, consult our detailed guide for cleaning or replacement.
Before replacing the spark plug, double-check the spark plug wire. Ensure it’s in good working order. Once finished, inspect everything to confirm optimal condition. Then, start your mower.
