Toro LX426 13AL60RG544 Operator's Manual

The Toro LX426 tractor should have its oil changed every 50 hours of operation or annually, whichever comes first. Air filters should be checked and cleaned every 25 hours and replaced if dirty. The blades and belts should be inspected every 10 hours, and the battery connections should be checked regularly.
First, ensure that the battery is fully charged and the connections are clean and tight. Check the fuel level and ensure the fuel valve is open. Inspect the spark plug for wear or damage and replace if necessary. Also, verify that the parking brake is engaged and the blades are disengaged.
For the Toro LX426, use SAE 10W-30 oil for general operating temperatures. If operating in colder conditions, SAE 5W-30 may be used. Always refer to the engine manufacturer's specifications for the most accurate recommendations.
To replace the drive belt on the Toro LX426, first disconnect the spark plug to ensure safety. Remove the deck by detaching the mower deck belt and lowering the deck to the ground. Then, remove the old drive belt and install the new one, ensuring it is routed correctly around the pulleys. Reattach the deck and reconnect the spark plug.
The recommended tire pressure for the Toro LX426 is 14 PSI for the front tires and 10 PSI for the rear tires. Always check the tire pressure when the tires are cold for the most accurate reading.
To sharpen the blades on a Toro LX426, first disconnect the spark plug. Remove the mower deck and then the blades. Secure the blade in a vice and use a file or grinder to sharpen the cutting edge, maintaining the original angle. Balance the blade before reinstalling it to ensure smooth operation.
Ensure the blades are sharp and balanced, and that the deck is level. Keep the underside of the deck clean from grass clippings and debris. Adjust the mowing height to avoid scalping and ensure even mowing. Regular maintenance and proper operating speed can also enhance cutting performance.
Excessive vibration in the Toro LX426 can be caused by unbalanced or damaged blades, loose engine mounting bolts, or debris lodged in the pulleys. Check the blades for damage and ensure they are properly balanced. Tighten any loose bolts and remove any debris from the mower deck.
Check if the blades are dull or damaged and sharpen or replace them as necessary. Ensure the deck is level and not tilted to one side. Verify that the blade spindles are not worn and replace them if needed. Also, adjust the mowing speed for optimal cutting.
To winterize the Toro LX426, clean the mower thoroughly to remove grass and debris. Change the oil and replace the oil filter. Add fuel stabilizer to the fuel system and run the engine for a few minutes. Remove the battery and store it in a cool, dry place. Finally, cover the tractor to protect it from dust and moisture.
