Simplicity 2690003 Prestige Parts Manual

To change the oil, first run the engine for a few minutes to warm it up. Turn off the engine and place a pan under the drain plug. Remove the plug and let the oil drain completely. Replace the plug and refill with the manufacturer-recommended oil. Be sure to check the oil level with the dipstick and adjust as necessary.
If your tractor won't start, check the battery connections to ensure they are tight and free of corrosion. Ensure the fuel tank has gas and that the fuel shut-off valve is open. Check the spark plug for wear or damage and replace if necessary. If the issue persists, a professional inspection may be needed.
Blade sharpening frequency depends on usage and terrain. Generally, you should inspect and sharpen your blades every 25 hours of mowing. Dull blades tear grass instead of cutting it, leading to a less attractive lawn and increased strain on the engine.
To clean the air filter, remove the cover and take out the filter. If it's a foam filter, wash it with warm soapy water, rinse, and allow it to dry completely. For paper filters, tap out dirt and replace if excessively dirty. Reinstall the filter and secure the cover.
To adjust the cutting height, locate the height adjustment lever or knob, usually near the seat or on the fender. Move the lever or turn the knob to the desired cutting height setting. Ensure the tractor is on a flat surface for accurate adjustment.
To winterize your tractor, clean the exterior and underside thoroughly. Change the oil and oil filter, fill the fuel tank and add a fuel stabilizer, and disconnect the battery or use a battery maintainer. Store the tractor in a dry place.
Uneven cutting can be caused by several factors. Check that the tire pressure is equal on all sides. Inspect the blades for sharpness and damage. Ensure the deck is level side-to-side and front-to-back. Adjust the deck as needed using the leveling instructions in the manual.
Use unleaded gasoline with an octane rating of 87 or higher. Avoid gasoline with more than 10% ethanol content. Fresh fuel should be used, and a fuel stabilizer is recommended if the tractor will be stored for an extended period.
To replace the drive belt, first ensure the tractor is on a flat surface and turn off the engine. Remove the mower deck if necessary, and locate the belt. Release the tensioner and remove the old belt. Install the new belt following the path of the old one, and reapply tension. Reattach the mower deck if removed.
Routine maintenance includes checking and changing the oil and filter, inspecting the air filter, checking tire pressure, cleaning the tractor after use, sharpening blades, and lubricating moving parts. Regularly inspect belts and replace them if worn.
