Ensure the parking brake is engaged, the PTO switch is off, and the gear shift lever is in neutral. Insert the key and turn it to the 'Start' position until the engine fires. Release the key to the 'Run' position once the engine starts.
Check the fuel level, ensure the battery is charged, and examine the spark plugs for damage. Also, verify that the safety interlock switches are functioning correctly.
Change the engine oil after the first 5 hours of use and then every 50 hours of operation or annually, whichever comes first.
Use SAE 30 oil for temperatures above 32°F (0°C) and SAE 5W-30 for temperatures below 32°F (0°C).
Check that the mower deck is level, ensure blades are sharp, and inspect for any obstruction under the deck. Adjust tire pressure and replace damaged blades if necessary.
Clean the tractor thoroughly, change the oil, add fuel stabilizer, and remove the battery. Store the battery in a cool, dry place and keep the tractor in a sheltered area.
First, disengage the PTO, lower the deck, and remove the belt guards. Remove the old belt and install the new one, ensuring it is properly seated in all pulleys. Reattach the belt guards and engage the PTO to test.
Check the cooling fins for debris and clean them if needed. Ensure the engine oil level is adequate and that the air filter is not clogged.
Locate the height adjustment lever on the tractor. Adjust the lever to the desired cutting height, ensuring both sides of the deck are set evenly.
Regularly check the oil level, air filter, tire pressure, belts, and blades. Also, inspect the battery connections and clean any debris from the cooling fins and engine compartment.
