brakes, place P.T.O. lever in " O F F " position and turn
ignition switch off. Remove the ignition key when the
tractor is not in use, or left unattended. If engine has been
working hard let it idle several minutes before shutting it
off. This will allow engine temperatures to normalize more
rapidly, preventing overheating.
