To maintain your Toro Wheel Horse 42-inch 78350 Mower, regularly check and change the oil, clean or replace the air filter, sharpen the blades, and inspect the belts for wear. Additionally, keep the mower deck clean and check the tire pressure.
If the mower doesn't start, check the fuel level, ensure the spark plug is clean and properly connected, inspect the air filter for blockages, and make sure the battery is charged. Also, verify the safety switches are engaged.
To adjust the cutting height, locate the cutting height adjustment levers on each wheel. Move the levers to the desired cutting height position, ensuring all wheels are set to the same height for an even cut.
If the blades are not engaging, check the PTO (Power Take-Off) switch for proper operation, inspect the mower deck belt for damage or misalignment, and ensure the battery is adequately charged.
Blades should be sharpened at least once per mowing season or after every 20-25 hours of use, depending on the terrain and frequency of use. Dull blades can tear grass, leading to uneven cuts.
To change the oil, run the engine for a few minutes to warm it up, then turn it off. Remove the oil drain plug and allow the old oil to drain completely. Replace the plug, add new oil, and check the level with the dipstick.
Ensure the air filter is clean, use fresh fuel, maintain proper tire pressure, and regularly service the engine. Additionally, avoid overloading the mower and mow at optimal speed for better efficiency.
Check the blades for sharpness and damage, ensure the mower deck is level, and verify the cutting height is consistent on all wheels. Adjust the mowing speed and overlap each pass slightly.
To winterize the mower, clean the deck and undercarriage, change the oil, add fuel stabilizer, disconnect the battery, and store the mower in a dry, sheltered area. Cover it to protect from dust and moisture.
During regular maintenance, inspect the spark plug, air filter, blades, belts, and tires. Also, check the battery connections, fuel system, and ensure all safety features are functioning correctly.
