A machine may include a powertrain drivingly connected to left and right front and rear wheels through a torque transfer unit to transfer torque to the front wheels as a function of a desired front torque and to the rear wheels as a function of a desired rear torque. At least one sensor of the machine may detect a value of an operating parameter indicative of a weight distribution of the machine across the wheels, and generate a parameter signal corresponding to the operating parameter. A control unit determines the weight distribution across the wheels as a function of the parameter signal, and the desired front and rear torques as a function of the weight distribution. The control unit also considers the weight and position of a load of material borne by an implement of the machine in determining the weight distribution.
