Abstract

The present disclosure relates to a ground sawing machine (30) comprising a control unit (210) and a frame (32) supported by rear wheels (34a, 34b) and front wheels (36a, 36b) arranged for enabling moving the ground sawing machine over a surface (38). A saw blade (2) is mounted to the frame and a first motor arrangement (40) is arranged to propel the saw blade (2) to cut against the surface (38). The rear wheels (34a, 34b) are adapted to be propelled by a second motor arrangement (6a, 6b) that comprises a first motor (6a) drivably connected to a first rear wheel (34a) and a second motor (6b) drivably connected to a second rear wheel (34b), where the rear wheels are attached to a rear wheel axle (46), and where a rear wheel turning angle (cp) is adjustable by means of an actuator (56) that is adapted to pivot the rear wheel axle (46). The control unit (210) is adapted to control the first motor (6a) and the second motor (6b) to propel the corresponding first rear wheel (34a) and second rear wheel (34b) independently and with either the same rotational velocity or with different rotational velocities.
