3. Installation Instructions

Replacing a drive belt requires careful attention to safety and proper procedure. If you are unsure about any step, consult a qualified service technician.

3.1 Safety Precautions

• Always turn off the engine and remove the spark plug wire to prevent accidental starting.
• Engage the parking brake.
• Wear appropriate personal protective equipment, including gloves and eye protection.
• Allow the engine and any hot components to cool down before beginning work.

3.2 Removal of Old Belt

1. Locate the drive belt routing diagram, usually found in your mower's owner's manual or under the hood.
2. Carefully disengage any tensioning pulleys or idlers.
3. Remove the old belt from the engine pulley, transmission pulley, and any guide pulleys. Note its routing for reference.

3.3 Installation of New Belt

1. Route the new MTD OEM-754-0280A drive belt according to the diagram, ensuring it is correctly seated in all pulley grooves.
2. Re-engage any tensioning pulleys or idlers. Ensure the belt has proper tension as specified by your mower's manufacturer.
3. Double-check all connections and ensure the belt is not twisted or pinched.
4. Reconnect the spark plug wire.
5. Test the mower's drive system at a low speed in a clear area before full operation.

Note: It is often recommended to replace both drive belts (if your model has two) at the same time for consistent performance.

4. Maintenance

Regular inspection and maintenance of your drive belt can extend its lifespan and ensure reliable operation of your riding mower or tractor.

• Visual Inspection: Periodically inspect the belt for signs of wear, cracks, fraying, glazing, or stretching.
• Tension Check: Ensure the belt maintains proper tension. A loose belt can slip, while an overly tight belt can cause premature wear on pulleys and bearings.
• Cleanliness: Keep the belt and pulleys free from debris, grass clippings, and oil, which can cause slippage and damage.
• Replacement: Replace the belt if any significant wear or damage is observed, or if it no longer maintains proper tension.
