Toro ProLine 60-inch 78478 Operator's Manual

To maintain your Toro ProLine 60-inch 78478 Mower, regularly check and replace the air filter, change the oil, sharpen the blades, and inspect the belts for wear and tear. Additionally, clean the mower deck after each use to prevent grass build-up.
The recommended oil type for the Toro ProLine 60-inch 78478 Mower is SAE 30 for temperatures above freezing and SAE 5W-30 for colder conditions. Always check the manufacturer's guidelines.
If your Toro ProLine 60-inch 78478 Mower won't start, check the fuel level, make sure the spark plug is clean and properly connected, and verify that the air filter is not clogged. Also, ensure that the battery is charged if applicable.
Uneven cutting can be caused by dull blades, uneven tire pressure, or an improperly adjusted deck. Sharpen the blades, check tire pressure, and ensure the deck is level.
To adjust the cutting height, locate the height adjustment levers on each wheel of the Toro ProLine 60-inch 78478 Mower. Move the levers to raise or lower the deck height according to your preference.
To winterize your mower, clean the deck, remove fuel or add a stabilizer, change the oil, remove the battery and store it in a cool, dry place, and cover the mower to protect it from dust and moisture.
To replace the drive belt, first disconnect the spark plug. Remove the deck, then release the belt tension. Remove the old belt and install the new one by following the diagram in the user manual. Reattach the deck and reconnect the spark plug.
Excessive vibration can be caused by unbalanced blades, loose parts, or damaged components. Check and balance the blades, tighten any loose parts, and inspect for damage that may need repair.
Blades should be sharpened after every 20-25 hours of use to maintain optimal cutting performance. Always check the blades for nicks and dullness before each use.
It is not recommended to mow wet grass as it can cause clumping, uneven cuts, and potential damage to the mower. Wait until the grass is dry for the best results.
