Construction machines have, in some instances been provided with an undercarriage that may be varied in width. The method by which these undercarriages are moved require support personnel, auxiliary equipment and an extensive amount of time to achieve the desired width. The present invention provides an undercarriage of variable gage wherein movement of the undercarriage components, between extreme positions may be obtained in a very timely and efficient manner from within the operator station of the machine.
