How do you drain the fuel tank on a Massey Ferguson 135?

To drain the fuel tank on a Massey Ferguson 135, first, ensure the tractor is turned off and parked on a level surface. Locate the fuel shut-off valve and turn it off to prevent fuel from flowing during the process. Then, remove the drain plug, typically located at the bottom of the fuel tank, and allow the fuel to flow into a suitable container. Once drained, replace the plug securely and dispose of the fuel according to local regulations.
