The recommended engine oil type for the Toro Z Master Z587L 74250 is SAE 10W-30 with an API service classification of SJ or higher.
The mower blades should be sharpened after every 25 hours of use or whenever you notice a decline in cutting performance.
To troubleshoot uneven cutting, check the tire pressure, ensure the mower deck is level, and inspect the blades for damage or dullness.
To change the air filter, remove the air filter cover, take out the old filter, and install a new one, making sure it is seated properly before replacing the cover.
Adjust the cutting height by moving the deck lift lever to the desired position. Refer to the operator's manual for specific height settings.
If the mower won't start, check the fuel level, battery charge, and ensure the parking brake is engaged. Also, inspect the spark plug for damage.
General maintenance, including oil changes, air filter replacement, and blade sharpening, should be performed every 25-50 hours of operation or annually, whichever comes first.
Use unleaded gasoline with an octane rating of 87 or higher and no more than 10% ethanol content.
To ensure battery longevity, regularly check and clean terminals, ensure a full charge, and store in a cool, dry place during the off-season.
To winterize the mower, clean the deck and blades, change the oil, add fuel stabilizer, and store it in a dry, sheltered area. Disconnect the battery if storing for an extended period.
