Toro Wheel Horse 12-38XL 71202 Operator's Manual

To change the oil, first ensure the tractor is on a level surface. Warm up the engine slightly to thin the oil, then turn it off. Place an oil pan under the drain plug, remove the plug, and let the old oil drain completely. Replace the drain plug and add new oil through the oil fill cap. Always use the oil type recommended in the owner's manual.
First, check the battery to ensure it is charged and the terminals are clean. Verify that the fuel tank is full and the fuel is fresh. Inspect the spark plug for wear or damage and replace if necessary. Ensure the safety switches are engaged, and the blades are disengaged. If the problem persists, consult the manual or a professional technician.
Adjust the cutting height by using the lever located on the right side of the tractor. Move the lever forward to lower the cutting height and backward to raise it. Make sure the tractor is on a flat surface and the engine is turned off before making adjustments.
During the off-season, clean the tractor thoroughly, removing any grass or debris. Change the oil and oil filter, and check the air filter. Stabilize the fuel or drain it completely. Lubricate moving parts and store the tractor in a dry, protected area. Disconnect the battery and store it in a cool, dry place.
To replace the drive belt, first, ensure that the tractor is turned off and on a flat surface. Remove the mower deck for easier access. Follow the belt routing diagram found in the manual to remove the old belt. Install the new belt, ensuring it is seated properly on all pulleys, and reattach the mower deck.
Common causes of overheating include a clogged air filter, low oil level, or debris blocking the cooling fins. Check and clean the air filter, ensure the oil level is adequate, and remove any debris from around the engine and cooling fins. If the issue persists, it may require professional servicing.
To sharpen the blades, first remove the mower deck and secure the blade with a block of wood. Use a wrench to remove the blade bolt. Sharpen the blade using a file or grinder, maintaining the original angle. Balance the blade before reinstalling to prevent excess vibration.
Check the drive belt for wear or damage and replace if necessary. Ensure that the belt tension is correct. Inspect the transmission fluid level and top it up if needed. If these steps do not resolve the issue, further diagnosis by a professional may be required.
The spark plug should be inspected every season and replaced annually or after 100 hours of use, whichever comes first. Always use the type of spark plug specified in the owner's manual to ensure proper engine performance.
Always read and understand the operator's manual before use. Wear appropriate clothing and safety gear. Keep bystanders, especially children, away from the mowing area. Ensure all safety devices are in place and functioning. Disengage blades and turn off the engine before making adjustments or cleaning.
