To change the oil, ensure the tractor is on a level surface. Remove the oil fill cap and drain plug. Allow the old oil to completely drain, then replace the drain plug. Fill with new oil up to the recommended level, and replace the fill cap.
Use fresh, unleaded gasoline with a minimum of 87 octane. Avoid using gasoline with more than 10% ethanol content to prevent engine damage.
Check the fuel level and ensure there is enough fresh fuel. Inspect the spark plug for wear or damage and replace if necessary. Verify that the battery is charged and the connections are clean and tight.
Ensure the PTO (Power Take-Off) is engaged. Check the blade drive belt for wear or damage, and replace if necessary. Inspect the PTO switch and related wiring for any issues.
Regular maintenance should be performed every 25 hours of operation or at least once per season. This includes changing the oil, checking the air filter, and inspecting the blades and belts.
Remove the blade from the tractor using a wrench. Sharpen the blade using a file or grinder, maintaining the original angle. Balance the blade before reinstalling it to avoid vibration.
Remove the air filter 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. Reinstall the filter and cover.
Check for debris blocking the air intake or cooling fins. Ensure the oil level is correct and the radiator is filled with coolant. If the problem persists, consult a professional technician.
Disconnect the negative cable first, followed by the positive cable. Remove the battery hold-down and take out the battery. Install the new battery, secure it with the hold-down, and reconnect the cables in reverse order.
Refer to the owner's manual for the exact tire pressure specifications. Generally, front tires are inflated to 14 PSI and rear tires to 10 PSI. Adjust according to specific requirements or conditions.
