2. Safety Information
WARNING: Always disconnect the spark plug wire or remove the battery before performing any maintenance or installation on your lawn mower to prevent accidental starting.
CAUTION: Lawn mower blades are sharp. Handle with extreme care. Wear heavy-duty gloves to protect your hands during installation and removal.
- Ensure the mower is on a flat, stable surface before beginning work.

3. Product Overview
The Husqvarna 582760502 is a Hi-Lift blade, designed to create a strong airflow under the mower deck. This airflow lifts grass blades for a cleaner, more even cut, and helps with bagging or collecting clippings. It is constructed from durable alloy steel for longevity and performance.

4. Setup and Installation
Follow these steps to safely replace your lawn mower blade:
- Prepare the Mower: Ensure the engine is off and cool. Disconnect the spark plug wire or remove the battery to prevent accidental starting. If applicable, engage the parking brake.
- Position the Mower: Tilt the mower onto its side with the carburetor facing upwards to prevent fuel leakage. Alternatively, lift the mower securely using a jack or ramps, ensuring it is stable.
- Remove Old Blade: Use a block of wood to wedge between the blade and the mower deck to prevent the blade from turning. Using a wrench, loosen the blade bolt by turning it counter-clockwise. Remove the bolt, washer, and the old blade. Note the orientation of the old blade for correct installation of the new one.
- Inspect Components: Check the blade bolt, washer, and blade adapter for wear or damage. Replace any worn parts.
- Install New Blade: Position the new Husqvarna 582760502 Hi-Lift Blade onto the blade adapter, ensuring the cutting edge faces the correct direction (usually towards the deck). The star-shaped hole on the blade should align with the adapter. Place the washer and blade bolt back on.
- Tighten Blade Bolt: Hand-tighten the blade bolt, then use a torque wrench to tighten it to the manufacturer's specified torque setting (refer to your mower's owner's manual for exact specifications). Use the wood block again to prevent the blade from turning.
- Final Check: Ensure the blade is securely fastened and spins freely without obstruction. Reconnect the spark plug wire or reinstall the battery.
5. Operating Instructions
Once the blade is correctly installed, operate your lawn mower according to its owner's manual. The Hi-Lift design of this blade is optimized for efficient cutting and improved grass collection, especially in conditions where a strong vacuum effect is beneficial. For best results, ensure the blade is sharp and balanced.
6. Maintenance
- Regular Inspection: Before each use, inspect the blade for any signs of damage, cracks, bends, or excessive wear.
- Sharpening: Sharpen the blade regularly to maintain cutting efficiency. A dull blade tears grass, leading to an unhealthy lawn. Ensure the blade remains balanced after sharpening to prevent excessive vibration and damage to the mower.
- Replacement: Replace the blade if it is severely bent, cracked, or worn beyond safe limits. A damaged blade can be dangerous and cause poor cutting performance.
- Cleaning: After each use, clean grass clippings and debris from the blade and underside of the mower deck. This prevents rust and maintains optimal airflow.
7. Troubleshooting
- Poor Cut Quality:
- Check if the blade is dull and requires sharpening.
- Ensure the blade is installed correctly with the cutting edge facing the right direction.
- Verify the blade is not bent or damaged.
- Excessive Vibration:
- A bent or unbalanced blade is a common cause. Replace or rebalance the blade.
- Ensure the blade bolt is tightened to the correct torque specification.
- Poor Grass Collection/Bagging:
- Check if the blade is dull or worn, reducing its lift capabilities.
- Ensure the underside of the mower deck is clean and free of caked-on grass, which can obstruct airflow.
