Toro Wheel Horse 52-inch 78252 Operator's Manual

Ensure that the mower is on a level surface. Insert the key into the ignition and turn it to the 'ON' position. Engage the choke if the engine is cold, then turn the key to the 'START' position while holding the brake pedal down. Release the key once the engine starts, and gradually disengage the choke.
Perform regular maintenance every 25 hours of operation or at the start of each mowing season. This includes checking the engine oil level, sharpening the blades, inspecting the air filter, and checking tire pressure. Replace the spark plug and change the oil every 100 hours.
Check the fuel level and ensure the fuel valve is open. Inspect the spark plug for wear or damage and replace if necessary. Make sure the battery is charged and the terminals are clean. Verify that the blades are disengaged and the brake pedal is fully depressed when starting.
First, check if the blades are sharp and balanced. Inspect for any debris or damage to the cutting deck. Ensure the tire pressure is consistent on all sides. Lastly, adjust the deck leveling as per the user manual instructions to achieve an even cut.
Clean the mower thoroughly to remove grass clippings and debris. Drain the fuel tank or add a fuel stabilizer. Change the oil and replace the oil filter. Remove the battery and store it in a cool, dry place. Cover the mower to protect it from dust and moisture.
Excessive vibration can be caused by unbalanced or damaged blades. Check for debris lodged in the deck and remove it. Ensure that all bolts and screws are tightened. If the issue persists, inspect the spindle bearings for wear and replace if necessary.
To improve fuel efficiency, ensure the engine is well-maintained with regular oil changes and clean air filters. Keep the blades sharp for efficient cutting, and mow at the recommended speed. Avoid mowing wet grass, which can increase engine load.
Use SAE 10W-30 motor oil for general use. For temperatures below freezing, use SAE 5W-30. Always refer to the owner's manual for specific recommendations based on your operating conditions.
Locate the cutting height adjustment lever on the side of the mower. Move the lever to the desired position to raise or lower the deck. Refer to the scale on the lever for height increments and ensure the deck is level on both sides.
Always wear appropriate safety gear, including goggles and ear protection. Check the area for debris before mowing. Do not mow on wet grass or slopes greater than 15 degrees. Keep hands and feet away from moving parts and never allow children to operate the mower.
