How To Change the Petrol on your Cub Cadet Ride- On | Zero-Turn & Lawn Tractor

Effortlessly learn how to drain old petrol from your lawn mower by following steps.

If your riding lawn mower has been stored in the shed throughout the winter, you may encounter stale petrol in the fuel system that requires removal. Stale petrol can lead to engine deposits and hinder combustion, resulting in poor performance. Prior to commencing the process of removing old process from your lawn mower, gather the necessary supplies. You’ll need an oil siphon pump to aid in the extraction, along with a suitable container for collecting and disposing of the unwanted petrol.


Step 1: Place your lawn mower on a level and flat surface before beginning the gas changing process.

Step 2: Safely turn off the mower, ensuring the engine has cooled down. Remove the ignition key and disconnect the spark plug wire to prevent accidental ignition.

Step 3: Unscrew the petrol cap located on the top of the riding lawn mower.

Step 4: Get ready to siphon the petrol into a separate collection container using a siphon pump.

Step 5: Prime the siphon pump by pumping the handle three or four times. Once the liquid starts flowing, it will continue without further pumping.

Step 6: After the old gas has been successfully drained, remove the oil siphon pump and set aside the collected gas for proper disposal.

Step 7: Refill the riding lawn mower with new pertrol. It’s recommended to mix in a fuel stabilizer with the new gas to extend its longevity, especially for end-of-season maintenance.

Step 8: Replace the gas cap securely and reconnect the spark plug ignition wire.

Step 9: Ensure proper disposal of the old etrol by taking it to a local waste disposal facility.

Once you’ve completed the petrol changing process, start the engine in a well-ventilated area and let the new gas cycle through for a few minutes before resuming lawn mowing. Regularly inspect the petrol, and if it appears contaminated or the engine runs unevenly, it’s time to replace the old petrol in your lawn mower.
