Learning how to turn on Craftsman lawn mower is the first step to a well-kept yard. Starting a Craftsman mower reliably involves a specific sequence of actions before you pull the cord. This guide covers every model, from older manual starts to modern electric key and push-button systems.
We will walk you through pre-start checks, the exact starting procedure, and solutions for when your mower won’t start. Following these steps ensures a safe and quick start every time.
How To Turn On Craftsman Lawn Mower
The core process for starting most Craftsman walk-behind mowers is consistent. Whether you have a classic side-pull model or a contemporary Briggs & Stratton engine, these steps form the foundation.
Always refer to your specific model’s manual for absolute certainty, as features can vary. Let’s begin with the essential safety and preparation steps.
Pre-Start Safety And Preparation Checklist
Before you even touch the starter cord, a few quick checks are crucial. These steps protect you, your property, and the mower’s engine from damage.
Neglecting preparation is a common reason a mower fails to start or runs poorly. Take two minutes to complete this list.
Inspect The Mowing Area
Clear the lawn of any debris like sticks, toys, rocks, or dog bones. These objects can become dangerous projectiles or damage the mower blade.
Ensure children and pets are indoors or at a safe distance from the area where you will be operating the mower.
Check The Engine Oil Level
Most Craftsman mowers have a dipstick for checking oil. Ensure the mower is on a level surface. Wipe the dipstick clean, reinsert it fully, and pull it out again to check the level.
The oil should be between the “Full” and “Add” marks. Using old or insufficient oil can seize the engine. Change the oil as recommended in your manual, typically every season or after 50 hours of use.
Verify The Fuel Level And Type
Use only clean, fresh gasoline that is less than 30 days old. Stale fuel is the number one cause of starting problems. For engines with a fuel valve, ensure it is in the “On” position.
If your mower has been stored for winter, you may need to drain the old gas from the carburetor and tank. Always use the fuel type specified in your manual, often regular unleaded with a minimum octane rating.
The Step-By-Step Starting Procedure
With the pre-checks complete, you are ready to start the engine. Follow these numbered steps in order. The exact controls may look slightly different on your model, but the sequence remains the same.
- Connect the Spark Plug Wire: Locate the rubber boot at the end of the spark plug wire. It should be firmly attached to the top of the spark plug. This is a critical safety interlock; the engine cannot start if it is disconnected.
- Prime the Engine (If Equipped): Find the primer bulb, usually a red or black rubber button on the engine. Press it 3 to 5 times slowly. You should see fuel moving through the clear fuel lines. Do not over-prime, as this can flood the engine.
- Set the Throttle Control: Move the throttle or engine speed lever to the “Fast” or “Start” position. This is often symbolized by a rabbit icon. Some models have this on the handle; others have it directly on the engine.
- Engage the Brake or Clutch: On self-propelled models, you must depress and hold the drive control lever against the handle. For all mowers, you typically must pull and hold a “blade control” lever against the upper handle. This lever is a safety feature that stops the blade when released.
- Pull the Starter Cord: Stand firmly with one foot slightly behind the other. Hold the upper handle with your left hand. With your right hand, pull the starter grip smoothly and rapidly. Do not yank it or let the cord snap back; guide it gently. It may take 2-3 pulls to start.
- Allow the Engine to Warm Up: Once the engine is running, let it idle for about 30 seconds before engaging the blade or beginning to mow. This allows oil to circulate and the engine to reach its optimal operating temperature.
Starting Specific Craftsman Mower Models
Craftsman manufactures several mower types, each with minor variations. Here’s how to adapt the core procedure for different models you might own.
Starting a Craftsman Riding Lawn Mower
Riding mowers have a more automotive-style starting process. Always sit in the seat before attempting to start, as a seat safety switch will prevent ignition.
- Ensure the parking brake is fully engaged.
- Set the gear shift to “Park” or “Neutral.”
- Move the throttle lever to the midway or “Choke” position.
- Turn the ignition key to the “On” position, then further to “Start.” Release the key once the engine cranks.
- If the engine is cold, you may need to use the choke. Adjust the throttle to a fast idle once running.
Starting a Craftsman Mower With an Electric Key
Many newer Craftsman mowers replace the recoil starter with a push-button electric start. This system uses a battery to power the starter motor.
- Insert the charged battery into its compartment on the mower deck or handle.
- Complete all previous safety steps (spark plug, brake, blade control).
- Press and hold the electric start button. The engine should crank and start within a few seconds. If it doesn’t, the battery may need recharging.
What To Do When Your Craftsman Mower Won’t Start
If you follow the correct procedure and the mower still fails to start, a systematic troubleshooting approach is needed. Start with the simplest solutions first.
Check The Obvious Issues First
Often, the problem is something simple that was overlooked in the starting sequence.
- Is the spark plug wire connected securely? Give it a firm push onto the plug.
- Is there fresh fuel in the tank? Old gas goes bad and clogs the carburetor.
- Is the oil level correct? A low-oil safety switch will prevent starting.
- Is the blade control lever held firmly against the handle? The safety interlock must be engaged.
- On riding mowers, are you fully seated? The seat switch must be depressed.
Diagnose Common Mechanical Problems
If the basics check out, these are the next likely culprits. Always disconnect the spark plug wire before inspecting the blade or underside.
- Flooded Engine: Smell gas? You may have over-primed. Wait 15 minutes, then try starting with the throttle set to “Fast” and no priming.
- Dirty Air Filter: A clogged filter starves the engine of air. Remove the filter cover and inspect the paper or foam filter. Tap it clean or replace it if it’s very dirty.
- Fouled Spark Plug: Remove the spark plug using a socket wrench. Check the electrode for heavy carbon buildup or damage. Clean it with a wire brush or replace it with a new plug gapped to your manual’s specification.
- Clogged Carburetor: Stale fuel leaves varnish that clogs the tiny jets in the carburetor. This often requires cleaning with carburetor spray or a professional service.
Essential Maintenance To Ensure Easy Starts
Regular maintenance is the best way to guarantee your Craftsman mower starts on the first pull every season. A little upkeep prevents most common starting issues.
End-Of-Season Storage Procedure
How you store your mower for winter directly impacts how easy it is to start in spring. Never just park it in the shed with a full tank of gas.
- Add a fuel stabilizer to a full tank of gas and run the engine for 5 minutes to circulate it through the carburetor. This prevents fuel from breaking down and gumming up the system.
- Disconnect the spark plug wire. Scrape grass clippings and debris from under the mower deck with a putty knife or brush.
- Change the engine oil and replace the air filter. Check the spark plug and replace if needed.
- Store the mower in a clean, dry place, preferably with the fuel tank full (treated with stabilizer) to prevent internal rust.
Beginning-Of-Season Tune-Up
When you take the mower out of storage, a quick tune-up gets it ready for action.
- Reconnect the spark plug wire if it was disconnected.
- Check the tire pressure and inflate to the PSI marked on the sidewall.
- Install a fresh spark plug if you didn’t do so before storage.
- Sharpen or replace the mower blade. A dull blade tears grass, leading to a brown, unhealthy lawn.
- Check all nuts and bolts, especially those on the wheels and blade adapter, for tightness.
Frequently Asked Questions
Where Is The Primer Bulb On A Craftsman Mower?
The primer bulb is typically a small, round, red or black rubber button located on the side of the engine. It’s often near the air filter cover. Pressing it forces a small amount of fuel directly into the carburetor to aid cold starting.
Why Does My Craftsman Mower Start Then Immediately Die?
This usually indicates a fuel delivery problem. Common causes include a clogged fuel filter, a closed fuel valve, a dirty carburetor jet, or a vent hole blockage in the gas cap. Try loosening the gas cap slightly to see if it runs longer; if so, clean or replace the cap.
What Is The Correct Way To Pull A Recoil Starter?
Use a smooth, rapid pulling motion. Do not yank it violently or pull the cord out at an angle. Let the cord retract gently back into the housing; never release it so it snaps back, as this can damage the starter mechanism.
How Do I Start A Craftsman Mower That Has Been Sitting For A Year?
First, drain all the old gasoline from the tank and carburetor bowl. Add fresh fuel. Check and likely change the oil. Inspect and clean or replace the air filter and spark plug. You may need to spray carburetor cleaner into the air intake to help loosen any varnish inside.
Is It Safe To Jump-Start A Lawn Mower With A Car Battery?
It is not recommended. A car’s electrical system has much higher amperage and can damage the mower’s sensitive wiring or starter motor. Use only a dedicated, small 12-volt charger or a purpose-built jump starter pack designed for small engines if your electric-start mower battery is dead.
