Toro Wheel Horse 71196 Operator's Manual

Ensure the tractor is in neutral, press the brake pedal, engage the parking brake, and turn the ignition key to start the engine.
Check the battery connections, ensure there is fuel in the tank, inspect the spark plug for wear, and verify the safety switches are engaged.
Change the oil every 50 hours of operation or at the start of each mowing season, whichever comes first.
Use SAE 30 oil for temperatures above 32°F (0°C) and 10W-30 for temperatures below 32°F (0°C).
Check if the mower deck is level, inspect the blades for damage or wear, and ensure that the tires are inflated to the correct pressure.
Stop the tractor immediately, allow it to cool down, check for debris blocking the air intake, and ensure the coolant level is adequate.
Use the height adjustment lever located on the side of the tractor to set the desired cutting height.
Regularly clean the deck to prevent grass build-up, check the blades for sharpness, and ensure that all nuts and bolts are tightened securely.
Disconnect the spark plug wire, use a spark plug wrench to remove the old plug, check the gap on the new plug, and install it by hand before tightening it with the wrench.
Inspect the blades for balance and damage, ensure the engine mounts are secure, and check for any loose bolts or components on the tractor.
