Simplicity 1694644 Legacy XL Parts Manual

To change the oil, first run the engine for a few minutes to warm it up. Turn off the engine and disconnect the spark plug wire. Place a pan under the oil drain valve, remove the oil drain cap, and let the oil drain completely. Replace the drain cap, and refill with the recommended oil type and quantity.
The recommended tire pressure for the front tires is 14 PSI and for the rear tires is 10 PSI. Always check the tire pressure when the tires are cold for an accurate reading.
If the tractor won't start, check the battery connections for corrosion, ensure the fuel tank is filled, verify that the fuel valve is open, and check the spark plug for wear or damage. If the issue persists, consult the manual or a professional technician.
Regular maintenance includes checking and changing the oil, inspecting the air filter, checking tire pressure, inspecting belts and blades, lubricating moving parts, and ensuring all nuts and bolts are tight.
To adjust the mowing deck, park the tractor on a flat surface and lower the deck. Measure the height from the ground to the blade tip on both sides. Adjust using the deck lift links until the blade tips are level and at the desired height.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using gasoline with more than 10% ethanol to prevent engine damage.
First, disconnect the spark plug wire. Use a spark plug wrench to remove the old spark plug. Check the gap on the new spark plug and adjust if necessary. Install the new spark plug by hand, then tighten with the wrench. Reconnect the spark plug wire.
Excessive vibration can be caused by unbalanced or damaged blades, loose parts, or worn belts. Inspect the blades for damage and balance, check all nuts and bolts, and inspect the belts for wear or damage.
Remove the air filter cover and take out the air filter. If it's a foam filter, wash it with soap and water, then let it dry. If it's a paper filter, tap it gently to remove debris or replace it if it's too dirty. Reinstall the filter and cover.
Check if the mowing deck is level and adjust if necessary. Inspect the blades for sharpness and damage, and sharpen or replace them if needed. Ensure the tire pressure is correct, as uneven tire pressure can affect the cutting height.
