A four wheel steering tractor comprising a grass cutting system vertically movably mounted in a lower space of the tractor between front and rear wheels. The grass cutting system carries gauge wheels disposed at opposite lateral sides in rear regions thereof. An interlocking structure between a steering wheel and the front and rear wheels includes a front drag link extending from a pitman arm toward the left (or right) front wheel, and a rear drag link extending from the pitman arm toward the right (or left) rear wheel. This interlocking structure places the center of tractor turning approximately on a straight line extending through the gauge wheels and adjacent one of the gauge wheels.
