Toro Wheel Horse 14-38XLE 71220 Operator's 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 oil drain plug. Remove the plug and allow the oil to drain completely. Replace the plug, then refill with the recommended oil type, checking the level with the dipstick.
The recommended spark plug for the Toro Wheel Horse 14-38XLE 71220 is a Champion RJ19LM or an equivalent. Ensure the gap is set to 0.030 inches (0.76 mm).
If your tractor won't start, check the battery connections for corrosion and ensure they are tight. Verify the fuel level and fuel filter condition. Examine the spark plug for fouling or wear, and replace if necessary.
To adjust the cutting height, locate the height adjustment lever on the side of the tractor. Move the lever to the desired cutting height position, ensuring both sides are set equally for an even cut.
If the blades are not engaging, check the PTO (Power Take-Off) switch and ensure it is in the 'on' position. Inspect the drive belts for damage or slippage and replace if needed. Also, check for any obstructions in the mower deck.
Regular maintenance should be performed at the start of each mowing season. This includes oil change, air filter replacement, spark plug inspection, and checking belts and blades. Refer to the owner's manual for specific intervals.
Before storing, clean the tractor thoroughly to remove grass and debris. Change the oil, add fuel stabilizer to the gas tank, and run the engine for a few minutes. Disconnect the battery and store it in a cool, dry place. Cover the tractor to protect it from dust.
To replace the drive belt, first disconnect the battery. Remove the mower deck and locate the drive belt. Release the tension on the belt by adjusting the tensioner pulley. Remove the old belt and install the new one, ensuring it is routed correctly around the pulleys. Reinstall the mower deck.
Overheating may be caused by a clogged air filter, low coolant levels, or debris blocking the cooling fins. Check and clean the air filter, ensure sufficient coolant, and remove any debris from the cooling fins.
To improve fuel efficiency, regularly maintain your tractor by changing the oil, replacing the air filter, and ensuring the spark plug is in good condition. Keep the blades sharp and properly inflated tires. Avoid mowing in wet conditions to reduce engine strain.
