Massey Ferguson four-wheel drive tractors are equipped with a two-speed system. To engage 4-wheel drive, the driver needs to press the 4WD button located on the dashboard. After pressing the 4WD button, the driver should then move the mode selector switch to the appropriate setting for 4-wheel drive (generally 4WD Hi). Once the mode selector is in position, the lights on the dashboard should indicate that 4-Wheel Drive is engaged.
