- Lasts longer: Preventive maintenance can extend the life of your mower and prevent costly repairs.
- Saves you money: A tuned-up mower operates more efficiently, consuming less fuel and reducing wear and tear.
Gather Your Tools and Supplies
Before you begin, gather the necessary tools and supplies for a smooth and successful tune-up. You’ll need:
- A Phillips screwdriver: For removing and tightening screws.
- A wrench set: For loosening and tightening nuts and bolts.
- A pair of pliers: For handling small parts and wires.
- A cleaning brush: For removing dirt and debris from the engine and other components.
- A spark plug wrench: To remove and install the spark plug.
- A fuel filter wrench (if needed): For removing and replacing the fuel filter.
- New spark plug (if needed): Check the recommended spark plug type in your owner’s manual.
- Engine oil: Choose the correct type and viscosity as specified in your owner’s manual.
- Air filter: Check for a replacement air filter.
- Fuel stabilizer (optional): To prevent fuel from degrading during storage.
- Gloves and eye protection: For safety during maintenance.
Prepare for the Tune-Up
Once you have your tools and supplies ready, follow these steps to prepare your Troy-Bilt lawn mower for a successful tune-up:
1. Safety First: Disconnecting the Spark Plug Wire
Prioritize safety by disconnecting the spark plug wire from the spark plug. This prevents accidental starting while you’re working on the mower.
2. Cleaning the Mower Deck and Undercarriage
Before you start any maintenance, thoroughly clean your Troy-Bilt lawn mower deck and undercarriage. Use a cleaning brush to remove any dirt, grass, or debris. This will make it easier to inspect and work on the mower.
3. Checking the Oil Level
With the engine cold, check the oil level using the dipstick. If the oil level is low, add oil to the correct level as specified in your owner’s manual.
4. Replacing the Air Filter
The air filter prevents dust and debris from entering the engine, keeping it clean and running smoothly. Inspect your air filter and replace it if it’s dirty or clogged.
Tuning Up the Engine
The engine is the heart of your Troy-Bilt lawn mower, and it’s essential to keep it in tip-top shape. Here’s how to tune up your engine:
1. Inspecting and Cleaning the Spark Plug
The spark plug is a crucial component responsible for igniting the fuel-air mixture in the combustion chamber. Regularly inspect and clean or replace your spark plug as needed.
a. Removing the Spark Plug:
Use a spark plug wrench to remove the spark plug. Carefully remove the spark plug wire to avoid damage.
b. Inspecting the Spark Plug:
Inspect the spark plug for signs of wear, such as excessive carbon buildup, cracks, or corrosion.
c. Cleaning the Spark Plug:
If the spark plug is dirty, you can clean it using a wire brush or sandpaper. However, if it’s severely worn or damaged, replace it with a new one.
d. Installing the Spark Plug:
Once you’ve cleaned or replaced the spark plug, thread it back into the cylinder head and tighten it using the spark plug wrench. Avoid overtightening, as it can damage the spark plug threads.
2. Adjusting the Carburetor
The carburetor mixes fuel and air before it enters the combustion chamber. If it’s not properly adjusted, your mower might run too rich or too lean. A properly adjusted carburetor is essential for optimal engine performance.
a. Understanding the Carburetor Adjustment Screws:
Most Troy-Bilt mowers have two adjustable screws on the carburetor:
- High-speed adjustment screw: Controls the fuel-air mixture at high engine speeds.
- Low-speed adjustment screw: Controls the fuel-air mixture at low engine speeds.
b. Adjusting the Carburetor:
Refer to your owner’s manual for specific adjustment procedures. It’s essential to make small adjustments, test the mower, and then make further adjustments as needed.
Maintaining the Cutting Deck
The cutting deck is responsible for mowing the grass. A well-maintained cutting deck will produce a clean and even cut.
1. Sharpening the Blade
A sharp blade is essential for a clean cut and a healthy lawn. If your blade is dull, it will tear the grass, leaving a ragged and uneven look.
a. Removing the Blade:
Use a wrench to loosen the blade bolt and remove the blade.
b. Sharpening the Blade:
Sharpen the blade using a file or a sharpening stone. Make sure to maintain a consistent angle along the entire blade edge.
c. Balancing the Blade:
After sharpening, balance the blade to ensure smooth and even operation.
2. Adjusting the Cutting Height
The cutting height adjustment lever allows you to control the height of the grass blades. Adjust the lever to the desired cutting height based on your preferences and the type of grass you’re mowing.
Maintaining Your Troy-Bilt Lawn Mower
Regular maintenance is key to keeping your Troy-Bilt lawn mower in top shape. Here are some additional tips:
- Store Your Mower Properly: When not in use, store your mower in a dry, clean area.
- Replace Fuel Lines and Filters: Over time, fuel lines and filters can deteriorate. Replace them as needed.
- Clean the Engine Regularly: Regularly remove any dirt and debris from the engine.
- Check Battery Terminals: Ensure the battery terminals are clean and properly connected.
- Consult Your Owner’s Manual: Always refer to your owner’s manual for specific maintenance instructions and recommendations.

Sometimes, even with proper maintenance, your Troy-Bilt lawn mower may experience issues. Here are some common problems and their potential solutions:
- Mower Won’t Start: Check the spark plug, fuel level, air filter, and battery connections.
- Mower Runs Poorly: Check the carburetor adjustment, air filter, and spark plug.
