Safety Precautions & Operating Instructions
Prioritize safety by carefully reviewing all precautions before operating your Craftsman 247.37. Understand proper starting, stopping, and mowing techniques for safe usage.
Pre-Operation Checklist
Before each use, a thorough pre-operation checklist is crucial for safe and efficient mowing with your Craftsman 247.37. First, always ensure the mower deck is clear of any objects – stones, sticks, or debris – that could become projectiles. Next, carefully inspect the blade for damage, cracks, or excessive wear; a damaged blade poses a significant safety hazard.
Confirm the oil level is within the recommended range, adding oil if necessary, and check the fuel level, ensuring it’s appropriate for the mowing area. Verify that all safety shields and guards are securely in place and functioning correctly. Inspect the air filter for cleanliness; a clogged filter reduces engine performance. Finally, always wear appropriate safety gear, including eye protection and sturdy footwear. A quick visual inspection of the entire machine can prevent unexpected issues and ensure a safe mowing experience.
Starting and Stopping the Engine
To start the Craftsman 247.37, ensure the blade is disengaged and the parking brake is set. Prime the engine by pressing the primer bulb several times (typically 3-5 times), then move the choke lever to the ‘choke’ position. Firmly grasp the handle and pull the starter rope with a smooth, controlled motion. Once the engine sputters, gradually move the choke to the ‘run’ position.
To stop the engine, release the handle, which will automatically engage the blade brake and stop the engine. Never attempt to stop the engine by simply disconnecting the spark plug wire. After stopping, allow the engine to cool completely before performing any maintenance. Always disengage the blade and ensure the mower is on a level surface before starting or stopping the engine for safe operation.
Safe Mowing Practices
Prioritize safety when operating your Craftsman 247.37. Always inspect the mowing area for stones, toys, or other objects that could become projectiles. Wear appropriate safety glasses and sturdy footwear. Never allow children or pets near the mowing area while the engine is running.
Mow across slopes, not up and down, to prevent loss of control. Reduce speed when turning or near obstacles. Never raise or lower the deck height while the engine is running. If the mower becomes clogged, stop the engine, disconnect the spark plug, and then clear the debris. Regularly inspect the blade for damage and sharpness, and replace as needed. Always disengage the blade before transporting or storing the mower.

Maintenance & Repair
Regular upkeep ensures your Craftsman 247.37 operates efficiently. This section details procedures for air filter changes, spark plug replacement, and blade maintenance for longevity.
Routine Maintenance Schedule
Maintaining your Craftsman 247.37 lawn mower requires a consistent schedule to ensure peak performance and extend its lifespan. After each use, inspect the mower deck for debris and clean thoroughly. Every 25 hours of operation, or at least once per season, check and tighten all bolts and fasteners. Inspect the drive belt for wear and tear, replacing if necessary.
Crucially, the air filter should be checked every 25 hours and cleaned or replaced as needed – a dirty filter restricts airflow and reduces engine efficiency. Oil levels must be checked before each use, and the oil changed every 50 hours or annually, whichever comes first. Sharpen the blade every 25 hours to maintain a clean cut. Finally, inspect the spark plug annually and replace it if it shows signs of fouling or wear, ensuring reliable ignition.
Air Filter Replacement

Replacing the air filter on your Craftsman 247.37 is a straightforward process vital for engine health. First, locate the air filter housing, typically near the engine. Remove the cover, often secured with clips or screws. Carefully remove the old air filter, noting its orientation for correct installation of the new one.
Before installing the new filter, inspect the air filter housing for any debris and clean it thoroughly. Ensure the new filter is the correct replacement for your model (247.37700.1 or 247.37237). Install the new filter, ensuring a proper seal. Reattach the air filter housing cover, securing it firmly. A clean air filter ensures optimal airflow, preventing engine damage and maintaining performance. Regular replacement, as per the maintenance schedule, is key.
Spark Plug Replacement
Replacing the spark plug on your Craftsman 247.37 lawn mower is crucial for reliable starting and efficient engine operation. Begin by disconnecting the spark plug wire, ensuring the engine is cool. Locate the spark plug, typically positioned on the engine block. Use a spark plug socket to carefully remove the old spark plug.
Before installing the new spark plug, check the gap using a feeler gauge and adjust if necessary to the manufacturer’s specification. Apply a small amount of anti-seize compound to the threads of the new spark plug. Thread the new spark plug in by hand to avoid cross-threading, then tighten it with the spark plug socket to the recommended torque. Reconnect the spark plug wire securely. A new spark plug restores ignition efficiency, improving performance and fuel economy.
Blade Sharpening and Balancing
Maintaining a sharp and balanced blade is essential for a clean cut and the longevity of your Craftsman 247.37 lawn mower. First, disconnect the spark plug wire for safety. Remove the blade, noting its orientation for correct reinstallation. Sharpen the blade using a metal file or a blade grinder, maintaining the original angle. Ensure both cutting edges are equally sharpened.
After sharpening, balance the blade using a blade balancer. If the blade is unbalanced, file metal from the heavier side until it balances evenly. An unbalanced blade causes excessive vibration, damaging the mower. Reinstall the blade, ensuring it’s facing the correct direction, and tighten the bolt to the manufacturer’s specified torque. Regular sharpening and balancing improve cutting performance and reduce strain on the engine.
Oil Change Procedure
Regular oil changes are crucial for maintaining the engine’s health in your Craftsman 247.37 lawn mower. Begin by warming the engine slightly, then disconnect the spark plug wire. Locate the oil drain plug, typically underneath the mower deck. Place an oil drain pan beneath the plug and remove it, allowing the old oil to drain completely.
Once drained, reinstall the plug securely. Remove the oil fill cap and add the recommended oil type and quantity, as specified in your owner’s manual – typically a 30W oil. Avoid overfilling. Check the oil level using the dipstick, adding more if needed. Properly dispose of the used oil at a recycling center. Consistent oil changes ensure smooth engine operation and extend its lifespan.

Troubleshooting Common Issues
Addressing problems like engine failure, blade malfunctions, or drive system issues is simplified with diagnostic steps and repair guidance for the Craftsman 247.37.
Engine Won’t Start
If your Craftsman 247;37 engine fails to start, begin with the basics. Ensure fresh fuel is in the tank and the fuel shut-off valve is open. A common culprit is a dirty or clogged air filter – inspect and replace it if necessary. Next, check the spark plug; a fouled or damaged spark plug won’t ignite the fuel. Remove it, inspect for wear, and replace if needed, ensuring the correct gap is maintained.
Low oil levels can also prevent starting, as a safety mechanism shuts down the engine. Verify the oil level and add oil if it’s low. Examine the safety bail; it must be fully engaged for the engine to operate. Finally, consider the starter rope – if it’s broken or jammed, the engine won’t crank. If these steps don’t resolve the issue, further diagnostics may be required, potentially involving the carburetor or ignition system.

Mower Blade Issues
Experiencing problems with the mower blade? Uneven cuts or excessive vibration often indicate blade issues. First, always disconnect the spark plug wire before inspecting or working on the blade. A dull blade tears grass instead of cutting it cleanly, leading to an unhealthy lawn. Sharpen the blade regularly, ensuring it’s balanced afterward to prevent vibration and potential damage to the mower.
Check for damage – nicks, bends, or cracks in the blade require immediate replacement. A bent blade throws the mower off balance and can be dangerous. Ensure the blade is securely fastened to the mower deck with the correct bolt and torque specification. Loose blades can fly off during operation. Regularly inspect the blade adapter for wear or damage, as this component is crucial for safe blade operation and a quality cut.

Drive System Problems
If your Craftsman 247.37 isn’t self-propelled, or the drive system is malfunctioning, several issues could be the cause. Begin by checking the drive belt for wear, cracks, or breakage. A worn belt will slip, resulting in a loss of power to the wheels. Inspect the belt tensioner; it should provide adequate pressure to maintain belt engagement.
Also, examine the drive cables for proper adjustment and connection. Loose or disconnected cables prevent the self-propel mechanism from functioning correctly. Check the drive wheel gears for damage or worn teeth. Finally, ensure the transmission fluid (if applicable to your model) is at the correct level and in good condition. Addressing these components systematically will help diagnose and resolve most drive system problems, restoring your mower’s self-propelling capability.
