The first warm days of spring finally arrive, and you’re eager to get your lawn looking its best. You pull your trusty MTD lawn mower out of storage, but then you’re faced with a daunting question: how do you even start it? Don’t worry, you’re not alone! Starting an MTD lawn mower can seem intimidating, but it’s actually quite simple with the right knowledge. This comprehensive guide will walk you through the steps, from pre-start preparation to troubleshooting common issues, so you can be mowing your lawn in no time.
What You Need to Know About Starting an MTD Lawn Mower
MTD lawn mowers are known for their reliability and ease of use. They come in a variety of models, including push mowers, riding mowers, and robotic mowers, each with its own unique starting procedure. This guide will primarily focus on starting gas-powered push mowers and riding mowers, the most common types. We’ll cover the essential steps, safety precautions, and troubleshooting tips to ensure a smooth and successful start every time.
Pre-Start Preparation: Setting the Stage for Success
Before even touching the starter cord, it’s crucial to prepare your MTD lawn mower for a smooth start. This involves a few simple yet vital steps:
1. Check the Fuel Level
An empty tank will leave you stranded, literally! Start by checking the fuel level in your mower’s tank. If it’s low, use fresh, clean gasoline. Avoid using old or stale fuel, which can cause starting problems and damage your engine.
2. Inspect the Spark Plug
The spark plug plays a critical role in igniting the fuel-air mixture. If it’s dirty or worn out, it can prevent the engine from starting.
How to Inspect the Spark Plug
- Locate the Spark Plug: It’s typically found on the top or side of the engine, near the cylinder head.
- Remove the Spark Plug: Use a spark plug wrench to loosen and remove the plug.
- Inspect the Spark Plug: Check for:
- Gap: The gap between the electrodes should be within the manufacturer’s specifications (usually around 0.030 inches).
- Condition: The electrode should be clean and free of carbon buildup.
- Wear: The electrode should be intact and not excessively worn.
Replacing a Worn or Dirty Spark Plug
- If the spark plug is dirty, clean it with a wire brush.
- If the spark plug is worn, replace it with a new one of the correct type and specifications.
3. Check the Air Filter
A dirty air filter restricts airflow to the engine, hindering combustion and making it difficult to start.
How to Inspect and Clean the Air Filter
- Locate the Air Filter: It’s usually located in a housing near the carburetor.
- Remove the Air Filter: Carefully remove the air filter from its housing.
- Inspect and Clean:
- Paper Filter: If it’s a paper filter, discard it if it’s dirty or damaged and replace it with a new one.
- Foam Filter: If it’s a foam filter, wash it with soap and water and allow it to dry completely before reinstalling it.
4. Make Sure the Blade is Sharp
A sharp blade cuts cleanly and efficiently, preventing damage to your lawn and improving your mower’s performance.
How to Sharpen the Blade
- Safety First: Disconnect the spark plug wire to prevent accidental starting.
- Secure the Blade: Use a wrench to loosen the blade bolt and remove the blade.
- Sharpen the Blade: Use a file or a sharpening stone to sharpen the cutting edge of the blade. Make sure to maintain the blade’s original angle.
- Reinstall the Blade: Tighten the blade bolt securely.
5. Inspect the Fuel Line
A cracked or leaking fuel line can prevent fuel from reaching the carburetor, making it impossible to start the engine.
How to Inspect the Fuel Line
- Visually Inspect: Examine the fuel line for cracks, leaks, or signs of damage.
- Check for Clogs: Make sure the fuel line is clear of any obstructions.
6. Check the Choke
The choke helps to enrich the fuel-air mixture during cold starts.
How to Use the Choke
- Cold Engine: Set the choke to the “choke” or “on” position.
- Warm Engine: Once the engine starts, gradually release the choke to its “off” position.
Starting Your MTD Lawn Mower: A Step-by-Step Guide
With the pre-start preparation completed, you’re ready to start your MTD lawn mower. Here’s a step-by-step guide:
1. Prime the Engine
Most MTD lawn mowers have a primer bulb, which helps to deliver fuel to the carburetor, making starting easier.
How to Prime the Engine
- Locate the Primer Bulb: It’s usually located near the carburetor.
- Prime the Engine: Press the primer bulb several times to fill the carburetor with fuel.
2. Engage the Choke
If the engine is cold, engage the choke to enrich the fuel-air mixture, helping it start more easily.
3. Pull the Starter Cord
- Safety First: Always stand to the side of the mower when pulling the starter cord.
- Grasp the Starter Cord: Hold the starter cord firmly and pull it slowly until you feel resistance. Then, pull it quickly and forcefully.
- Repeat: If the engine doesn’t start on the first pull, repeat the process.
4. Release the Choke Gradually
Once the engine starts, gradually release the choke to its “off” position. This allows the engine to run smoothly.
5. Let the Engine Warm Up
Allow the engine to warm up for a few minutes before engaging the blades. This ensures that the engine is running at its optimal temperature and prevents damage.
6. Engage the Blades
Once the engine is warmed up, you can engage the blades to begin mowing. Most MTD lawn mowers have a lever or button to control the blades.
Troubleshooting Common Starting Problems
Even with the proper preparation and starting procedure, you might encounter issues with your MTD lawn mower. Here are some common starting problems and troubleshooting tips:
1. The Engine Won’t Start
Possible Causes:
- Empty Fuel Tank: Check the fuel level and refill it if needed.
