A Quick Overview
Changing your Troy-Bilt lawn mower blades is a relatively simple DIY task that can significantly improve the quality of your lawn mowing experience. The process involves safely disconnecting the mower, removing the old blades, installing the new ones, and finally, sharpening them to ensure optimal performance. This article will provide detailed instructions on each step, along with essential safety tips and troubleshooting advice.
1. Assessing Your Troy-Bilt Lawn Mower Blades
Before you even think about changing your lawn mower blades, it’s crucial to assess their current condition. Here’s how to determine if you need new blades:
1. Visual Inspection:
- Bent or Damaged Blades: Look for any visible bends, cracks, or chips in the blade. These imperfections can lead to uneven cuts and damage your lawn.
- Dullness: Dull blades will leave behind a ragged, uneven cut and may even tear the grass. Inspect for signs of wear and tear, such as a shiny, smooth edge rather than a sharp, rough one.
2. The “Paper Test”:
- Cut a Piece of Paper: This simple test can quickly assess the sharpness of your blades. If the blade slices through the paper cleanly without any resistance, it’s sharp enough. If it tears or wrinkles the paper, it’s time for a replacement.
3. Frequency of Use:
- High-Frequency Use: If you mow frequently, your blades will wear down faster. It’s a good idea to replace them every season or every 25 hours of operation, depending on the manufacturer’s recommendation.
2. Gathering the Necessary Tools and Supplies
Before you begin, make sure you have the following tools and supplies:
- New Mower Blades: Ensure you choose the correct size and type of blades for your Troy-Bilt model. You can find these at most hardware stores or online retailers.
- Wrench: A 7/16″ or 9/16″ wrench will be needed to remove and install the blades, depending on your mower model.
- Gloves: Protective gloves are always a good idea to prevent cuts and scratches.
- Safety Glasses: Protect your eyes from flying debris.
- Cleaning Supplies: A brush or cloth for cleaning the mower deck after blade replacement.
- Optional: Blade Sharpening Equipment: If you prefer to sharpen your old blades rather than replace them, you’ll need a blade sharpening kit or access to a sharpening service.
3. Preparing Your Troy-Bilt Lawn Mower for Blade Change
Safety is paramount when working with machinery, so take these steps to ensure a safe working environment:
1. Disconnect the Spark Plug:
- Remove the Spark Plug Wire: To prevent accidental engine ignition, disconnect the spark plug wire from the spark plug. This ensures the engine won’t start while you’re working on the mower deck.
- Locate the Spark Plug Wire: The spark plug wire is usually located on the engine cylinder.
2. Secure the Mower:
- Chock the Wheels: Place a solid object behind the wheels to prevent the mower from rolling while you’re working.
- Level the Mower: If you have access to a jack or blocks, lift the mower deck slightly to make the blade replacement easier.
3. Clean the Mower Deck:
- Remove Debris: Use a brush or cloth to remove any grass clippings, dirt, or other debris from the underside of the mower deck. This will give you a clear view of the blades and ensure you don’t accidentally leave any foreign objects in the deck.
4. Removing the Old Blades
Now, let’s get those old blades out:
1. Locate the Blade Bolts:
- Look for the Bolts: There will be two or three bolts holding the blades in place, located on the bottom of the mower deck.
2. Loosen the Blade Bolts:
- Use the Correct Wrench: Depending on your Troy-Bilt model, you’ll need a 7/16″ or 9/16″ wrench to loosen the bolts.
- Counter-Clockwise Rotation: Turn the bolts counter-clockwise to loosen them.
- Safety Tip: It’s a good idea to hold the blade in place with your hand while you loosen the bolts to prevent it from spinning freely.
3. Remove the Blades:
- Lift the Blade: Once the bolts are loosened, carefully lift the blade away from the mower deck. It may be slightly attached by a spring, so pay attention to how it comes off.
- Discard or Store: Once the blades are removed, dispose of them properly or store them for future sharpening.
5. Installing the New Blades
With the old blades out of the way, it’s time to install the new ones:
1. Align the New Blades:
- Proper Orientation: Ensure the blades are properly aligned with the mower deck. Most blades have a “top” or “bottom” side.
- Sharp Edge Placement: The sharp edge of the blade should face downwards towards the ground.
2. Secure the Blades:
- Align the Holes: Carefully align the bolt holes on the blades with the holes on the mower deck.
- Tighten the Bolts: Securely tighten the bolts clockwise. Use a socket wrench for better torque control and avoid over-tightening.
- Tighten Evenly: Tighten each bolt evenly to ensure that the blade is securely attached.
3. Check for Stability:
- Spin the Blades: Once the bolts are tightened, gently spin the blades to make sure they rotate freely and without any wobble.
6. Sharpening Your New Blades
While new blades come sharp, they’ll eventually dull with use. Here’s how to keep them in top condition:
1. Sharpening Method:
- Sharpening Stone or File: A sharpening stone or file is a common and effective method for sharpening lawnmower blades.
- Professional Sharpening Service: If you don’t feel comfortable sharpening the blades yourself, you can always take them to a professional sharpening service.
2. Sharpening Technique:
- Angle: Maintain a consistent angle while sharpening. The ideal angle is typically between 25-30 degrees.
- Even Sharpening: Ensure you sharpen the entire length of the blade to maintain a consistent cutting edge.
- Safety First: Always wear protective gear and ensure the blade is properly secured while sharpening.
7. Reassembling Your Troy-Bilt Lawn Mower
With the new blades installed and sharpened, it’s time to put your Troy-Bilt lawnmower back together:
1. Connect the Spark Plug Wire:
- Secure Connection: Connect the spark plug wire back to the spark plug. Ensure it’s properly attached and secure.
2. Remove the Chocks:
- Clear the Path: Remove any chocks or blocks that were holding the mower in place.
3. Test Run:
- Start the Mower: Once everything is back in place, start the mower and let it run for a few minutes to ensure everything is working properly.
- Inspect for Issues: Listen for any unusual noises or vibrations. If you encounter any issues, stop the mower and troubleshoot the problem.
8. Maintenance Tips for Optimal Performance
Here are some helpful tips for keeping your Troy-Bilt lawnmower in optimal working condition:
- Regular Inspections: Regularly inspect the blades for wear and tear.
- Mow Regularly: Avoid letting grass grow too long before mowing.
- Clean After Each Use: Clean the mower deck and blades after each use to prevent grass build-up and rust.
- Proper Fuel Storage: Store the mower in a cool, dry place, and ensure the fuel tank is empty if you’re not using the mower for an extended period.
