Toro Wheel Horse 38-inch 78225 Operator's Manual

To start the Toro Wheel Horse 38-inch 78225 mower, ensure the transmission is in neutral, engage the parking brake, and turn the ignition key to the 'start' position while ensuring the throttle is set to 'choke' if the engine is cold.
The recommended maintenance schedule includes checking the oil level before each use, changing the oil every 25 hours of operation, cleaning the air filter every 25 hours, and sharpening the blades at least once a season.
If the mower won't start, check the battery for charge, ensure the fuel tank is filled, inspect the spark plug for any damage, and make sure the safety switches are engaged properly.
Use SAE 30 oil for temperatures above 32°F (0°C) and SAE 5W-30 for temperatures below 32°F (0°C) to ensure optimal engine performance.
To adjust the cutting height, locate the height adjustment lever on the side of the mower deck and move it to the desired position. Ensure both sides are adjusted equally to maintain an even cut.
Excessive vibration can be caused by unbalanced blades, loose parts, or debris lodged in the mower deck. Check and tighten any loose bolts and inspect the blades for balance and damage.
After use, remove grass clippings and debris from the mower deck using a garden hose or compressed air. Avoid using high pressure that might damage the deck components.
To winterize the mower, clean the deck, change the oil, add a fuel stabilizer to the gas tank, 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 spark plug, first disconnect the spark plug wire, use a spark plug wrench to remove the old plug, and install the new plug by hand before tightening it with the wrench. Reconnect the spark plug wire once done.
Uneven cuts can be caused by dull blades, improper deck leveling, or uneven tire pressure. Ensure the blades are sharp, the deck is level, and all tires are inflated to the recommended pressure.
