Keeping your Husqvarna riding mower in top shape means more than just regular oil changes and fuel top-offs. The blades are the heart of your mowing system, and dull or damaged blades can leave you with uneven cuts, scalped lawns, and even potential damage to your mower. This comprehensive guide will walk you through the process of changing your Husqvarna riding mower blades, ensuring your lawn stays pristine and your mower performs at its peak.
A Quick Overview of the Blade Change Process
Changing your riding mower blades might seem daunting, but it’s a fairly simple process that can be accomplished with basic tools and a little patience. First, you’ll need to disconnect the mower’s spark plug to prevent accidental starting. Then, you’ll use a wrench to remove the blade bolts and detach the blades. Once you’ve installed the new blades, you’ll reverse the process to reassemble your mower.
Preparing for the Blade Change
1. Gathering Your Supplies
Before you begin, ensure you have the following tools on hand:
- A socket wrench: This is crucial for removing the blade bolts. The size required will depend on your mower model, so refer to your owner’s manual for specifics.
- A torque wrench: This specialized wrench allows you to tighten bolts to a specific pressure, ensuring proper blade installation and preventing damage.
- Gloves: Protect your hands from sharp blades and potential dirt and debris.
- Safety glasses: Always wear safety glasses to protect your eyes from flying debris.
- New mower blades: Ensure you purchase the correct blades for your Husqvarna riding mower model.
2. Safety First: Disconnecting the Spark Plug
Preventing accidental starts is paramount. To ensure your safety, always disconnect the spark plug before working on the mower blades:
- Locate the spark plug: Refer to your owner’s manual for the exact location of the spark plug on your mower model.
- Remove the spark plug wire: Carefully pull the spark plug wire off the spark plug terminal. It’s usually held in place by a clip or a small lever.
- Check for secure disconnection: Ensure the wire is completely disconnected and out of the way.
3. Positioning the Mower for Blade Access
For easier access to the blades, you’ll need to elevate the mower deck. Here’s how:
- Engage the parking brake: This prevents the mower from rolling while you’re working on it.
- Locate the jack points: Your Husqvarna mower will have designated jack points on the frame. Consult your owner’s manual for the exact location.
- Lift the deck: Use a jack or jack stands to safely lift the mower deck to a height that allows you to comfortably work on the blades.
Removing the Old Blades
1. Removing the Blade Bolts
With the deck raised and the spark plug disconnected, you’re ready to remove the blades:
- Identify the blade bolts: The blade bolts are usually located on the underside of the mower deck, near the center of the blade.
- Use the socket wrench: Place the appropriate socket wrench over the blade bolt and turn it counter-clockwise to loosen the bolt.
- Remove the bolt: Once the bolt is loosened, completely remove it from the blade.
2. Removing the Blades
With the bolts removed, you can now detach the blades:
- Carefully lift the blade: Grab the blade with a firm grip, ensuring you are lifting straight up. Don’t pull or twist the blade.
- Remove the blade: Once the blade is clear of the deck, carefully set it aside in a safe location.
Installing the New Blades
1. Inspecting the New Blades
Before installing the new blades, it’s crucial to ensure they’re in good condition:
- Check for damage: Inspect the new blades for any bends, cracks, or other damage that could affect their performance.
- Confirm correct blade type: Double-check that the new blades are specifically designed for your Husqvarna riding mower model.
- Identify the blade’s sharp edge: Make sure the sharp edge of the blade is facing the proper direction (usually towards the center of the mower deck).
2. Installing the New Blades
Now, you can install the new blades:
- Align the blade: Place the new blade onto the spindle shaft, ensuring it’s correctly aligned with the deck.
- Tighten the blade bolts: Use the socket wrench to tighten the blade bolts securely, but avoid overtightening. Refer to your owner’s manual for the specified torque settings.
Reassembling and Finishing Touches
1. Lowering the Deck
Once the new blades are installed, you can lower the mower deck back to its normal position:
- Lower the deck carefully: Use the jack or jack stands to slowly lower the mower deck back down, ensuring the blades clear the ground before fully lowering the deck.
2. Reconnect the Spark Plug Wire
Before starting the mower, reconnect the spark plug wire:
- Reattach the spark plug wire: Carefully align the spark plug wire terminal with the spark plug and press it firmly onto the terminal.
- Check for secure connection: Ensure the wire is securely connected to prevent any potential issues.
3. Test Run and Final Adjustments
After reassembling, test your mower to ensure proper operation:
- Start the mower: Start the mower according to the manufacturer’s instructions.
- Inspect for issues: Listen for any unusual noises or vibrations that could indicate a problem with the blades or the installation.
- Adjust blade height: If necessary, adjust the blade height using the mower’s height adjustment lever to achieve the desired cut length.
Maintaining Your Mower Blades
1. Regular Blade Sharpening
Dull blades are the main culprit for uneven cuts and can even damage your lawn. It’s essential to sharpen your mower blades regularly:
- Sharpen every 10-15 hours of use: This frequency may vary depending on the type of grass and the intensity of use.
- Use a file or a sharpening tool: Follow the manufacturer’s instructions for sharpening the blades.
2. Storing Blades Properly
Proper storage ensures the longevity of your blades:
- Clean the blades: Before storing, clean the blades with a wire brush to remove any dirt or debris.
- Store blades securely: Store the blades in a dry, clean place to prevent rust and damage.
When to Replace Mower Blades
Even with regular sharpening, mower blades will eventually need to be replaced. Here are some signs that it’s time for new blades:
- Severe nicks or bends: Significant damage to the blade can affect the cut quality and even lead to mower damage.
- Excessive wear: If the blades are excessively worn down or have lost their original sharpness, it’s time for new ones.
- Irregular cutting pattern: Noticeable inconsistencies in the cut height or a ragged, uneven cut are indicative of dull or damaged blades.
