摘要：
The present invention relates to a ground sawing machine comprising a frame supported by rear wheels (34a, 34b) and front wheels (36a, 36b) arranged for moving the ground sawing machine over a surface (38). At least one motor (40, 6) and a saw blade (2) are mounted to the frame, at least one motor (40) being arranged to propel the saw blade (2) to cut against the surface (38). The pointing direction (80) relative the surface (38) of the rear wheels (34a, 34b) and/or the front wheels (36a, 36b) is adjustable by means of an electrically controlled actuator (56) which is controlled by means of control means (70, 71, 72) arranged to provide at least three different control signals, one for left turn, one for right turn and one for center. The control signal for left turn and right turn are arranged for adjusting the pointing direction (80) of the adjustable wheels (34a, 34b) correspondingly, and the control signal for center is arranged for adjusting the pointing direction (80) of the adjustable wheels (34a, 34b) to a predetermined value.
