Toro Z Master 60-inch 72915 Operator's Manual

To change the oil, first run the engine for a few minutes to warm it up. Then, turn off the engine and remove the ignition key. Place an oil pan under the drain plug, remove the plug, and let the oil drain completely. Replace the drain plug, remove the oil filter, and install a new one. Finally, refill with the recommended oil type and capacity.
Check the fuel level and ensure the fuel valve is open. Inspect the battery connections for corrosion and ensure they are tight. Verify that the spark plug is clean and properly connected. If the problem persists, consult the user manual or contact a professional technician.
It is recommended to sharpen the mower blades every 25 hours of use or at least once per mowing season to ensure a clean cut and promote healthy grass growth.
Excessive vibration may be caused by unbalanced blades, damaged spindles, or a loose deck. Inspect the blades for damage or imbalance and check that all deck components are securely fastened. Replace any damaged parts as necessary.
After ensuring the engine is off and the ignition key is removed, use a garden hose to spray the underside of the deck, removing grass clippings and debris. For thorough cleaning, use a plastic scraper to remove stubborn buildup. Regular cleaning prevents rust and maintains optimal performance.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol, as it can cause damage to the engine components.
To adjust the cutting height, locate the cutting height adjustment lever on each wheel. Move the lever to the desired position, ensuring all wheels are set to the same height for an even cut.
Ensure that the tire pressure is equal on all four tires and adjust if necessary. Check that the blades are sharp and properly balanced. Also, verify that the deck is level from front to back and side to side.
First, disconnect the spark plug and remove the mower deck. Release the tension on the belt by adjusting the tensioner, then remove the old belt. Install the new belt following the belt routing diagram in the manual. Reassemble and test the mower.
Maintain regular servicing, including air filter and spark plug replacement. Keep the blades sharp for efficient cutting, and avoid mowing wet grass. Regularly check and inflate tires to the recommended pressure to reduce rolling resistance.
