If you’re looking for a clear guide on how to start a lawn mower Craftsman, you’ve come to the right place. Starting a Craftsman lawn mower generally involves setting the throttle control to the appropriate starting position. This initial step is crucial for both manual and electric start models. The process is straightforward once you understand the basic controls and safety steps.
This article will walk you through every step, from pre-start checks to troubleshooting a stubborn engine. We’ll cover different models, including push mowers and riding tractors. You’ll learn the correct sequence to get your mower running smoothly every time.
How To Start A Lawn Mower Craftsman
Before you pull the starter rope or turn the key, a few preparatory steps are essential. These steps ensure safety and prime the engine for a reliable start. Skipping them is a common reason for starting problems.
First, always perform these checks in a well-ventilated outdoor area. Never attempt to start a mower in a garage or shed due to carbon monoxide risk. Clear the mowing area of debris like sticks, toys, and stones.
Pre-Start Checklist And Safety
A quick pre-operation check takes just a minute but can prevent damage and injury. Make this a habbit every time you prepare to mow.
- Check the Oil Level: Use the dipstick to ensure the oil is at the full mark. Low oil can cause severe engine damage.
- Inspect the Air Filter: A dirty air filter restricts airflow and makes starting difficult. Tap it clean or replace it if it’s very dirty.
- Add Fresh Gasoline: Use clean, unleaded gas with the correct octane rating. Old gas (over 30 days) can cause starting issues. For ethanol-blended fuel, consider a stabilizer.
- Examine the Spark Plug: A fouled or damaged spark plug is a top cause of no-starts. Check the connection and condition.
- Engage the Safety Features: Ensure the blade control lever (deadman’s handle) is released and the parking brake is set on riding models.
Understanding Your Craftsman Mower Controls
Familiarizing yourself with the controls is key. While layouts vary, most Craftsman mowers have similar core components.
- Throttle Control: This lever, often marked with a turtle and rabbit, sets the engine speed. For starting, it should be set to “Fast” or the choke position.
- Choke Lever: Found on many manual start models, it enriches the fuel mixture for a cold start. It’s usually a separate lever or part of the throttle control.
- Blade Control Lever (Deadman’s Handle): This must be held down against the handle to keep the engine running on push mowers. Releasing it cuts the engine.
- Primer Bulb: A small rubber button you press 3-5 times to draw fuel into the carburetor before starting.
- Ignition Key: Used on electric-start push mowers and all riding mowers.
- Brake/Clutch Pedal: On riding mowers, you must often depress the brake to start the engine.
Step-By-Step Starting Procedures
The exact steps differ slightly depending on your mower type. Follow the instructions for your specific model.
Starting A Craftsman Push Mower With Manual Recoil
This is the most common type. The process is simple when done in the correct order.
- Move the mower to a flat, clear patch of grass or pavement.
- Check the oil and gas levels as described in the pre-start checklist.
- Locate the throttle control lever on the engine. Slide it to the “Fast” position or to the choke symbol if the engine is cold.
- If your model has a primer bulb, press it firmly 3 to 5 times. Do not over-prime.
- Grasp the handle firmly with one hand. With your other hand, hold the blade control lever (deadman’s handle) down against the main handle.
- Pull the starter rope smoothly and briskly. Do not yank it to its full length; use a controlled pull. It may take 2-3 pulls to start.
- Once the engine starts, if you used the choke, gradually move the throttle lever to “Fast” as the engine warms up.
Starting A Craftsman Push Mower With Electric Key Start
These models use a battery to power the starter motor. They are very convenient.
- Complete all pre-start checks. Ensure the battery is charged.
- Insert and turn the ignition key to the “On” position. Do not turn to “Start” yet.
- Set the throttle control to “Fast” or the choke position.
- Press the primer bulb if equipped.
- Hold the blade control lever against the handle.
- Turn the ignition key to “Start” and hold it until the engine cranks and starts. Release the key immediately once it starts.
- Adjust the choke as needed after starting.
Starting A Craftsman Riding Lawn Mower Or Tractor
Riding mowers have additional safety interlocks that must be engaged for starting.
- Ensure the mower is on level ground. Set the parking brake fully.
- Make sure the PTO (blade engagement lever) is in the “Off” or disengaged position. The engine will not start with the blades engaged.
- Depress the brake pedal completely. On some models, you must also depress the clutch.
- Place the gear shift lever in “Neutral” or “Park.”
- Set the throttle lever to about the mid-point or the “Choke” position for a cold engine.
- If the engine is cold, pull the choke knob out (if equipped).
- Turn the ignition key to “On,” then to “Start.” Release the key as soon as the engine starts.
- After the engine runs for a moment, push the choke knob in gradually.
Why Won’t My Craftsman Lawn Mower Start? Troubleshooting Guide
Even with proper procedure, your mower might not start. Here are the most common causes and fixes.
Common Issues And Quick Fixes
Work through this list methodically before assuming a major repair is needed.
- Engine Doesn’t Turn Over (No Sound): Check the battery connection on electric start models. Ensure the blade control lever is fully engaged. Check for a blown fuse.
- Engine Cranks But Won’t Start: This often points to a fuel or spark issue. Check for old gas, a clogged fuel line, or a closed fuel valve. Verify the spark plug wire is connected.
- Engine Starts Then Dies Immediately: This can indicate a clogged carburetor jet, a dirty air filter, or a problem with the blade control safety system. Check that you are holding the lever down firmly.
- Backfires or Sputters: Often caused by stale fuel or an incorrect choke setting (choke left on too long). Check your fuel first.
Fuel System Problems
Fuel issues are the leading cause of starting failures, especially after winter storage.
- Stale Gasoline: Gas degrades in as little as 30 days. Drain the old fuel from the tank and carburetor bowl, then refill with fresh gas.
- Clogged Fuel Filter: Locate the in-line fuel filter. If it’s dark or dirty, replace it.
- Clogged Carburetor: Varnish from old gas can clog the tiny jets inside the carburetor. This may require a carburetor cleaning kit or replacement.
- Fuel Valve Closed: Some models have a shut-off valve on the fuel line. Make sure it is in the “On” position.
Ignition And Electrical Problems
If fuel isn’t the issue, the problem may be with spark or safety switches.
- Fouled Spark Plug: Remove the spark plug. If the electrode is blackened or wet, clean it with a wire brush or replace it. Ensure the gap is correct.
- Loose Spark Plug Wire: Ensure the wire is pushed firmly onto the plug terminal.
- Faulty Safety Switch: Riding mowers have switches under the seat, on the brake pedal, and at the PTO lever. If one fails, it prevents starting. Diagnosing these may require a multimeter.
- Dead Battery (Electric Start): Check battery terminals for corrosion. Test the voltage; a reading below 12 volts likely means the battery needs charging or replacement.
Seasonal Starting Tips And Maintenance
Proper storage and maintenance make starting your Craftsman mower much easier next season.
End-Of-Season Storage (Winterization)
Preparing your mower for storage prevents most spring starting headaches.
- Add fuel stabilizer to a full tank of gas and run the engine for 5 minutes to circulate it through the carburetor. This prevents varnish buildup.
- Disconnect the spark plug wire for safety.
- Change the engine oil while it’s warm, as old oil contains contaminants.
- Remove and clean or replace the air filter.
- Clean the underside of the mower deck to prevent rust.
- Store the mower in a dry, covered place.
Spring Tune-Up For Easy Starting
A simple spring service gets your mower ready for the season.
- Change the engine oil if you didn’t in the fall.
- Install a new spark plug. It’s an inexpensive and effective upgrade.
- Replace the air filter.
- Check and sharpen the mower blade.
- Reconnect the spark plug wire, check the tire pressure, and you’re ready to go.
Frequently Asked Questions (FAQ)
Where Is The Primer Bulb On A Craftsman Lawn Mower?
The primer bulb is typically a small, red, rubber button located on the side of the engine, near the air filter cover. Not all Craftsman models have one; some use a choke system instead. If present, pressing it 3 to 5 times before starting draws fuel into the carburetor for a quicker start.
What Position Should The Throttle Be In To Start A Craftsman Mower?
For a cold start, set the throttle lever to the “Choke” position or to “Fast.” The choke position is often indicated by a symbol. For a warm engine that has been recently run, you can usually start it with the throttle set to “Fast” without using the choke. Always consult your owner’s manual for the specific recomendation for your model.
Why Does My Craftsman Mower Only Start With Starting Fluid?
If your mower requires starting fluid to start, it means fuel is not reaching the combustion chamber. This strongly points to a fuel system issue. Common culprits include stale gas, a clogged fuel filter, a blocked fuel line, or a dirty carburetor. Using starting fluid frequently can damage the engine, so it’s best to diagnose and fix the underlying fuel problem.
How Do I Start A Craftsman Lawn Mower After Winter?
Starting after winter storage often involves addressing old fuel. First, drain any old gasoline from the tank and carburetor bowl. Add fresh fuel. Check the oil level and air filter. You may need to replace the spark plug. Follow the standard starting procedure, but be prepared to pull the recoil rope a few extra times as fuel refills the system.
What Safety Precautions Should I Take Before Starting?
Always wear sturdy shoes and eye protection. Start the mower outdoors only, never in an enclosed space. Clear the mowing area of people, pets, and debris. Ensure all safety interlocks are functioning, like the blade control lever on push mowers and the seat switch on riders. Never bypass these safety features.
