Frequently Asked Questions

Q1: What tools do I need to remove a DeWalt lawnmower blade?

You will need a few basic tools to remove a DeWalt lawnmower blade safely. The most important is a wrench that fits the blade bolt, which is typically a 13mm or 19mm size. You will also need a pair of work gloves to protect your hands, and a block of wood or a small piece of lumber to help hold the blade in place.

Having a pair of safety glasses is also recommended, as small metal chips may fly off when loosening the blade bolt. It’s important to note that some newer DeWalt lawnmowers might require specialized tools for removing the blade. If you’re unsure, consult your owner’s manual.

Q2: Why do I need to remove the DeWalt lawnmower blade?

There are several reasons why you might need to remove the DeWalt lawnmower blade. One common reason is to sharpen the blade. A dull blade will leave your lawn uneven and can even damage the grass. You may also need to remove the blade if you need to replace it, or if you need to access the underside of the deck for cleaning or maintenance.

Removing the blade also gives you the opportunity to inspect it for any signs of damage, such as cracks or chips. Damaged blades can cause uneven cuts and may even throw debris, creating a safety hazard.

Q3: How do I know when to sharpen my DeWalt lawnmower blade?

A dull lawnmower blade will leave your grass with a ragged, uneven cut. You may also notice that the grass is being torn instead of cut cleanly. If you see any signs of damage or rust on the blade, it’s also a good indication that it’s time for sharpening.

A good rule of thumb is to sharpen your blade every 20-30 hours of use, or at least once a year. However, the frequency of sharpening will depend on the type of grass you’re cutting and how often you use your mower.

Q4: How do I safely remove the spark plug wire before working on the blade?

It’s crucial to disconnect the spark plug wire before working on the DeWalt lawnmower blade. This ensures that the engine cannot accidentally start while you’re working on it. To safely disconnect the spark plug wire, locate the wire connected to the spark plug.

Gently pull the wire connector off the spark plug, making sure the wire is not damaged or loose. Ensure the wire is placed away from the spark plug so that it doesn’t accidentally reconnect. It’s also a good practice to tape the wire to a part of the engine to prevent accidental contact.

Q5: What is the best way to hold the blade in place while loosening the bolt?

You should never attempt to hold the blade in place with your hand while loosening the bolt, as this is extremely dangerous. Instead, you should use a block of wood or a small piece of lumber to wedge between the blade and the deck.

This will keep the blade from spinning while you loosen the bolt. Ensure the block of wood is positioned securely and is not obstructing any other parts of the mower. Avoid using anything soft or flimsy as it might slip and cause the blade to move unexpectedly.

Q6: How do I safely install the DeWalt lawnmower blade back on the mower?

Once you’ve sharpened the blade or installed a new one, it’s important to install it back onto the mower correctly. First, ensure that the blade is securely positioned on the spindle. Align the blade with the mounting holes and then thread the bolt back onto the spindle.

Hand-tighten the bolt until it’s snug, then use the wrench to tighten it further. However, be careful not to overtighten the bolt, as this can damage the spindle or the blade. Refer to your DeWalt lawnmower manual for the recommended tightening torque.

Q7: What should I do if I experience difficulties removing the blade?

If you are having trouble removing the blade, do not force it. Forcing the blade could damage the spindle or the blade. Try using a lubricant like penetrating oil on the bolt to loosen it. If the problem persists, it’s best to consult your DeWalt lawnmower manual or a qualified technician for help.

If the blade bolt is seized or rusted, you might need to use a specialized tool like a breaker bar or an impact wrench to loosen it. But it’s best to avoid using these tools if you are not comfortable working with them. Always prioritize safety and seek professional help if needed.
