Ever started your Husqvarna lawnmower, ready to tackle your yard, only to find the blades aren’t spinning? A broken or worn drive cable could be the culprit. This critical component connects the engine to the mower deck, allowing you to propel the machine and cut grass. While it might seem daunting, replacing a drive cable is a manageable DIY task. This comprehensive guide will walk you through the process, step-by-step, equipping you with the knowledge and confidence to fix your Husqvarna lawnmower and get back to mowing.
Overview
Replacing a drive cable on a Husqvarna lawnmower is a relatively straightforward process involving removing the old cable, attaching a new one, and making adjustments to ensure proper tension. It requires basic hand tools, a replacement drive cable specific to your mower model, and some patience.
Assessing the Problem: Is It Really the Drive Cable?
Before jumping into the replacement process, it’s crucial to ensure the problem lies with the drive cable. Here’s a quick checklist:
1. Engine Problems: A non-functional engine will, naturally, prevent the blades from spinning. Ensure your mower starts and runs properly.
2. Belt Condition: Inspect the belt connecting the engine to the mower deck. A worn, broken, or loose belt can also cause a lack of blade engagement.
3. Clutch Engagement: Most Husqvarna lawnmowers have a clutch system that disengages the blades when the drive lever is released. Check if the clutch is engaging properly. If the clutch isn’t engaging, the blades won’t spin even with a working drive cable.
4. Drive Cable Condition: Visually inspect the drive cable for any signs of damage, fraying, or excessive wear. If you notice any of these, a replacement is likely necessary.
5. Drive Lever Issues: Ensure the drive lever moves freely and engages the drive cable properly.
6. Mower Deck Problems: A jammed or obstructed mower deck can prevent the blades from turning. Clean the deck and remove any debris that might be hindering movement.
Once you’ve eliminated other potential causes, and you’re confident the drive cable is the culprit, you can proceed with the replacement.
Gathering Your Tools and Supplies
Before you begin, gather the following tools and supplies:
- New Drive Cable: Order the correct drive cable for your specific Husqvarna model. You can find this information in your owner’s manual or by contacting a Husqvarna dealer.

Replacing the Drive Cable: A Step-by-Step Guide
Now, let’s dive into the replacement process:
1. Disengage the Blades: Always start by disconnecting the spark plug wire to prevent accidental starting.
2. Remove the Mower Deck: Consult your owner’s manual for specific instructions on removing the deck from your model. It typically involves removing bolts or clips that secure the deck to the mower frame.
3. Identify the Drive Cable: Locate the drive cable, which runs from the drive lever mechanism to the mower deck.
4. Disconnect the Old Cable: Using your adjustable wrench, loosen the nut securing the drive cable to the drive lever mechanism. You may need to use a flat head screwdriver to pry the cable free if it’s stuck.
5. Disconnect the Cable from the Deck: Locate the cable connection point on the mower deck. This point may vary depending on your model. Release the cable from the deck using a wrench or pliers.
6. Remove the Old Cable: Carefully pull the old drive cable out of the mower. If it’s tangled, slowly and gently disentangle it to avoid damaging other components.
7. Install the New Cable: Thread the new drive cable through the same path as the old cable. Be sure to route the cable correctly; the ends should be correctly aligned.
8. Connect the New Cable to the Deck: Secure the new cable to the deck using the same method you used to remove the old cable. Ensure the cable is properly tensioned.
9. Connect the Cable to the Drive Lever: Secure the new cable to the drive lever mechanism using the same nut and tightening method you used for the old cable.
10. Reattach the Mower Deck: Reattach the mower deck to the mower frame, ensuring all bolts or clips are securely tightened.
11. Adjust Drive Cable Tension: With the deck attached, adjust the drive cable tension to ensure the blades engage smoothly when the drive lever is activated.
12. Test the Drive System: Reconnect the spark plug wire and start the engine. Engage the drive lever and check if the blades rotate smoothly. If the blades spin too fast or too slow, you’ll need to readjust the drive cable tension.
13. Clean Up: Discard the old drive cable and clean up any debris from your work area.
