The culprit could be a worn-out drive control cable, the lifeline connecting your mower’s engine to its wheels. Replacing it might seem daunting, but with the right tools and clear instructions, you can tackle this repair and bring your mower back to life. This comprehensive guide will walk you through the process, from identifying the problem to installing a new drive control cable, ensuring you have all the information needed to confidently take on this DIY project.
A Quick Overview
Replacing a Craftsman lawn mower’s drive control cable is a relatively straightforward repair that can be accomplished with basic tools and a bit of patience. The process involves disconnecting the old cable, routing a new one, and securing it to the engine and drive system. This article will provide detailed instructions, troubleshooting tips, and safety precautions to ensure a smooth and successful repair.
Identifying a Faulty Drive Control Cable
Before diving into the replacement process, it’s crucial to confirm that your lawn mower’s drive control cable is indeed the issue. Here are some common signs that point towards a faulty cable:
1. Engine Runs But Mower Doesn’t Move: If your engine starts and runs smoothly, but the mower remains stationary when the drive lever is engaged, the drive control cable might be the culprit.
2. Sluggish or Jerky Movement: If your mower moves, but it struggles to maintain a consistent speed or moves in fits and starts, a worn-out drive control cable could be hindering smooth power transmission.
3. Drive Lever Feels Loose or Unresponsive: A worn-out drive cable can become loose and slack, causing the drive lever to feel floppy or unresponsive. This indicates that the cable is no longer transmitting the necessary force to engage the drive system.
4. Visible Damage to the Cable: Inspect the cable for any signs of fraying, breakage, or kinks. These visible damages can significantly impede the cable’s functionality and warrant a replacement.
5. Check for Proper Tension: The drive control cable should have a slight amount of tension when the drive lever is in the “engaged” position. If the cable feels loose or slack, it might need to be adjusted or replaced.
6. Eliminate Other Potential Issues: Before concluding that the drive control cable is the problem, rule out other potential issues such as a clogged air filter, fuel issues, or a faulty spark plug.
Gather Your Tools and Materials
Before you begin, gather the necessary tools and materials:
Tools:
- Phillips Head Screwdriver: This will be used to remove and tighten screws.

- Wire Cutters: These will be used to cut the old drive control cable.
- Pliers: These will be used to grip and tighten clamps.
- Socket Wrench Set: This will be used to loosen and tighten bolts that secure the drive system components.
- Adjustable Wrench: This will be used to tighten nuts and bolts.
Materials:

Step-by-Step Guide to Replacing the Drive Control Cable
Now that you have your tools and materials ready, follow these steps to replace your Craftsman lawn mower’s drive control cable:
Step 1: Disassemble the Drive System
1.1 Disconnect the Spark Plug Wire: Before beginning any work on the drive system, disconnect the spark plug wire to prevent accidental starting.
1.2 Remove the Mower Deck: Depending on your Craftsman model, the mower deck may need to be removed to access the drive system. Consult your mower’s manual for specific instructions.
1.3 Locate the Drive Control Cable: The drive control cable will run from the engine’s governor to the drive system.
1.4 Disconnect the Cable from the Engine: Locate the cable’s connection point on the engine. This is usually a small lever or arm. Use a flat-head screwdriver or pliers to loosen the clamp securing the cable to the engine.
1.5 Disconnect the Cable from the Drive System: Follow the cable to where it connects to the drive system, typically near the drive wheel. Disconnect the cable by loosening the clamp or releasing the lever.
Step 2: Remove the Old Drive Control Cable
2.1 Trace the Cable’s Route: Follow the path of the old cable to understand how it is routed through the mower frame.
2.2 Cut the Cable: Use wire cutters to cut the old cable at a point where it is easily accessible.
Step 3: Install the New Drive Control Cable
3.1 Route the New Cable: Carefully feed the new drive control cable through the same path as the old one.
3.2 Connect to the Drive System: Connect the new cable to the drive system by securing it to the lever or clamp.
3.3 Connect to the Engine: Attach the new cable to the engine’s governor, securing it with the clamp. Ensure the cable is properly seated and snug.
Step 4: Reassemble the Drive System
4.1 Reinstall the Mower Deck: If you removed the mower deck, carefully reinstall it, ensuring all bolts and screws are securely tightened.
4.2 Connect the Spark Plug Wire: Reconnect the spark plug wire.
4.3 Test the Drive System: Start the engine and engage the drive lever. Verify that the mower moves smoothly and without any jerking or stalling.
Step 5: Lubricate and Secure the Cable
5.1 Lubrication: Apply a generous amount of waterproof grease to the cable’s ends, especially at the connection points. This will help prevent corrosion and ensure smooth movement.
5.2 Secure the Cable: Use wire ties or zip ties to secure the cable to the mower’s frame at intervals. This will prevent the cable from rubbing against moving parts.
Step 6: Final Adjustments and Testing
6.1 Drive Control Adjustment: If the drive system doesn’t function correctly, adjust the drive control cable’s tension.
6.2 Test and Enjoy: Test the drive system again, and if everything works as intended, you’re ready to mow!
Troubleshooting Common Issues
1. Cable Binding: If the cable binds or snags during installation, ensure it is routed correctly and free of obstructions.
2. Incorrect Cable Length: If the new cable is too short or too long, it will prevent proper operation. Ensure you purchased the correct cable for your Craftsman lawn mower model.
3. Tightening Clamps: Make sure all clamps securing the cable to the engine and drive system are properly tightened to prevent slippage.
4. Drive System Adjustments: If the drive system still doesn’t function correctly after replacing the cable, consult your Craftsman mower’s manual for information on adjusting the drive system components.
5. Professional Assistance: If you encounter persistent issues or feel uncomfortable completing the repair yourself, consult a qualified lawn mower repair technician.
Safety Precautions
1. Disconnect the Spark Plug Wire: Always disconnect the spark plug wire before working on the drive system to prevent accidental starting.
2. Wear Protective Gear: Use safety glasses to protect your eyes from debris, and work gloves to prevent cuts and scrapes.
3. Work in a Well-Ventilated Area: Avoid working on your mower in enclosed spaces, as exhaust fumes can be harmful.
4. Lift Safely: When lifting or moving heavy components, use proper lifting techniques to prevent injury.
5. Use Caution with Sharp Tools: Handle tools like screwdrivers and wire cutters with care.
