Simplicity 990400 Landlord 2012 Parts Manual

To change the oil, first warm up the engine to ensure the oil flows out smoothly. Turn off the engine and place an oil pan under the drain plug. Remove the plug and allow the oil to drain completely. Replace the drain plug and refill with the recommended oil type and amount, which can be found in your owner's manual.
If your engine won't start, first check the battery connections for corrosion or looseness. Ensure the fuel tank has fuel and the fuel valve is open. Check for a blown fuse or a disconnected safety switch. If these are not the issues, inspect the spark plugs for wear or damage.
Routine maintenance should be performed according to the guidelines in your owner's manual, typically after every 50 hours of operation or annually, whichever comes first. This includes checking and replacing the oil, air filter, and inspecting all belts and hoses.
Uneven cutting can be caused by a misleveled deck, dull blades, or improper tire pressure. Check and adjust the deck level as per the manual instructions. Sharpen or replace blades if needed. Ensure all tires are inflated to the recommended pressure.
The recommended fuel for the Simplicity 990400 Landlord 2012 Tractor is unleaded gasoline with a minimum octane rating of 87. Avoid using fuels with more than 10% ethanol, as they can damage the engine.
To improve traction, consider using tire chains or weights. Ensure the tires are in good condition and properly inflated. Adjust your mowing speed and pattern to adapt to the terrain conditions.
If your tractor is overheating, check the coolant level and ensure there are no leaks. Clean any debris from the radiator and cooling fins. Also, inspect the fan belt for proper tension and wear.
To replace the drive belt, first disconnect the battery and remove the mower deck. Release the tension on the belt by adjusting the tensioner, then remove the old belt. Install the new belt, ensuring it is properly aligned on all pulleys, then reattach the mower deck and reconnect the battery.
Symptoms of a failing spark plug include difficulty starting the engine, poor acceleration, decreased fuel efficiency, and rough idling. Inspect the spark plug for signs of wear, such as carbon buildup or a cracked insulator.
For off-season storage, clean the tractor thoroughly and change the oil. Add a fuel stabilizer to the fuel tank and run the engine for a few minutes. Disconnect the battery and store it in a cool, dry place. Cover the tractor with a breathable cover and store it in a dry, sheltered location.
