To adjust the cutting height, locate the height adjustment lever on the side of the mower deck. Move the lever to your desired cutting height position, which ranges from 1.5 to 4.5 inches. Ensure the lever is securely set in place.
First, check the PTO (Power Take-Off) switch to ensure it is in the "on" position. If the blades still do not engage, inspect the PTO fuse and replace if necessary. Additionally, examine the belt for wear or damage.
It's recommended to change the oil every 100 hours of operation or at least once per mowing season, whichever comes first. Make sure to use oil that meets Toro specifications.
Uncut strips can be caused by dull blades, so ensure they are sharpened regularly. Also, check that the mower deck is level and not clogged with grass clippings.
Regularly check the battery terminals for corrosion and clean them as needed. During off-season storage, disconnect the battery and keep it on a trickle charger to maintain charge.
Use unleaded gasoline with an octane rating of 87 or higher. Ensure the fuel contains no more than 10% ethanol to prevent engine issues.
Check the spark plug for wear or damage and replace if necessary. Ensure the fuel filter and air filter are clean. Also, verify that fresh fuel is in the tank.
After each use, remove grass clippings and debris from the mower deck using a garden hose or air blower. Allow the deck to dry completely before storing the mower.
Symptoms include a squealing noise, uneven cutting, or a loss of drive power. Inspect the belt for cracks, fraying, or glazing and replace if necessary.
Clean the mower thoroughly, change the oil, and stabilize the fuel. Store the mower in a dry location and disconnect the battery. Cover the mower to protect it from dust and moisture.
