To change the oil, first ensure the mower is on a level surface. Warm up the engine to allow the oil to drain more easily. Turn off the engine and disconnect the spark plug. Remove the oil drain plug and allow the oil to drain completely into a suitable container. Replace the drain plug and refill with the recommended oil type and amount.
Toro recommends using SAE 10W-30 or SAE 30 oil for the Wheel Horse 48-inch 78265 mower, depending on the temperature range you are operating in. SAE 10W-30 is suitable for general use.
If the mower won't start, check the fuel level and ensure there is fresh fuel. Verify the spark plug is connected and in good condition. Inspect the air filter for dirt or debris. Make sure the safety switch is engaged and the battery connections are secure.
Blades should be sharpened at least once a season or after every 25 hours of use. If you notice uneven cutting or torn grass, it may be time to sharpen the blades.
The recommended tire pressure for the Toro Wheel Horse 48-inch 78265 mower is typically 12-15 PSI for the rear tires and 10-12 PSI for the front tires. Always refer to the manual for specific details.
To adjust the cutting height, locate the height adjustment lever on the mower deck. Move the lever to the desired cutting height position, ensuring it clicks into place. Verify the adjustment on both sides for an even cut.
Smoke from the engine can be caused by an overfilled oil reservoir, a clogged air filter, or oil spillage on the engine. Check and correct the oil level, clean or replace the air filter, and wipe away any spilled oil.
Excessive vibration can be caused by unbalanced or damaged blades, loose parts, or debris caught in the mower deck. Check and balance or replace the blades, tighten any loose parts, and clear any debris.
To replace the drive belt, first disconnect the spark plug and remove the mower deck. Locate the drive belt and note its path for reinstallation. Remove the belt from the pulleys and install the new belt following the same path. Reattach the mower deck and reconnect the spark plug.
Regular maintenance includes checking and changing the oil, inspecting and replacing the air filter, sharpening the blades, checking the tire pressure, and cleaning the mower deck. Refer to the user manual for a detailed maintenance schedule.
