Safety Information
WARNING: Always prioritize safety when working with machinery. Failure to follow these safety instructions may result in serious injury or damage to equipment.
- Ensure the lawn tractor's engine is turned off and the spark plug wire is disconnected before beginning any work. This prevents accidental starting.
- Engage the parking brake to prevent the tractor from moving.
- Wear appropriate personal protective equipment (PPE), including safety glasses and work gloves.
- Allow the engine and any hot components to cool down completely before touching them.
- If the tractor needs to be lifted, use a stable and appropriate lifting device and secure it properly with jack stands. Never rely solely on a jack.
- Keep children and pets away from the work area.
- If you are unsure about any step, consult a qualified service technician.

Installation Instructions
Before proceeding, ensure you have read and understood all safety information. Refer to your Husqvarna CTH 126 owner's manual for specific diagrams and additional instructions related to your tractor model.
1. Drive Belt Installation (Part Number: 532125907)
- Prepare the Tractor: Park the tractor on a flat, level surface. Turn off the engine, remove the ignition key, and disconnect the spark plug wire. Engage the parking brake.
- Access the Drive System: Depending on your specific CTH 126 model, you may need to remove the mower deck or other covers to gain access to the drive belt system. Consult your tractor's manual for detailed steps on accessing these components.
- Remove the Old Drive Belt: Carefully observe the routing of the old drive belt around the engine pulley, transmission pulley, and any idler pulleys. Use a camera to take pictures if necessary for reference. Release tension on the idler pulleys (if applicable) and remove the old belt.
- Install the New Drive Belt: Route the new Aliris of ISE drive belt (532125907) exactly as the old one was installed. Ensure it sits correctly in all pulley grooves.
- Tension and Verify: Re-tension any idler pulleys. Manually rotate the pulleys to ensure the belt is properly seated and moves freely without binding.
- Reassemble: Reinstall any covers or the mower deck that were removed.
2. Deck Belt Installation (Part Number: 532419271)
- Prepare the Tractor: As with the drive belt, ensure the tractor is off, key removed, spark plug wire disconnected, and parking brake engaged.
- Remove the Mower Deck: For most CTH 126 models, the mower deck must be removed from the tractor to access the deck belt. Follow the instructions in your tractor's owner's manual for safe deck removal.
- Observe Belt Routing: Before removing the old deck belt, carefully note or photograph its routing around the spindle pulleys and any idler pulleys on the mower deck.
- Remove the Old Deck Belt: Release tension on the idler pulleys (if applicable) and remove the worn deck belt.
- Install the New Deck Belt: Route the new Aliris of ISE deck belt (532419271) precisely according to the observed routing. Ensure it is seated correctly in all pulley grooves.
- Tension and Verify: Re-tension any idler pulleys. Manually rotate the blades to ensure the belt is properly seated and moves freely.
- Reattach Mower Deck: Reinstall the mower deck onto the tractor, following your owner's manual.
- Final Checks: Reconnect the spark plug wire. Test the mower deck engagement at a low engine speed in a safe, open area before full operation.
Maintenance
Regular inspection and maintenance of your belts will extend their lifespan and ensure optimal performance of your Husqvarna CTH 126.
- Visual Inspection: Periodically inspect both the drive and deck belts for signs of wear, such as cracks, fraying, glazing, or stretching. Replace belts showing significant wear.
- Cleanliness: Keep belts and pulleys free from grass clippings, dirt, and debris. Accumulations can cause premature wear and slippage.
- Tension: Ensure belts maintain proper tension. Refer to your tractor's owner's manual for correct tensioning procedures. Over-tensioning can damage belts and pulleys, while under-tensioning can lead to slippage and inefficient operation.
- Storage: If storing the tractor for an extended period, ensure belts are clean and free from tension if recommended by the tractor manufacturer.
Troubleshooting

|---|---|---|
| Tractor not moving or moving slowly (Drive Belt) | Worn, stretched, or broken drive belt; incorrect belt tension; seized transmission pulley. | Inspect and replace drive belt (532125907) if worn or broken. Adjust belt tension. Check transmission pulley for free movement. |
| Mower blades not engaging or cutting poorly (Deck Belt) | Worn, stretched, or broken deck belt; incorrect belt tension; seized spindle pulley. | Inspect and replace deck belt (532419271) if worn or broken. Adjust belt tension. Check spindle pulleys for free movement. |
| Squealing noise from belts | Loose belt tension; glazed belt; misaligned pulleys; debris on pulleys. | Check and adjust belt tension. Clean pulleys and belts. Inspect for proper pulley alignment. Replace glazed belts. |
| Belts frequently coming off pulleys | Incorrect belt routing; worn or damaged pulleys; bent belt guides; incorrect belt size. | Verify correct belt routing. Inspect pulleys and belt guides for damage. Ensure correct belt part numbers are used. |
