The ratio step between fifth and sixth smaller than all the other ratio steps. The three gears range are designed for f - highway use and slow - moving operations (curb pouring, material spreading, heavy load, steep grade). Only start the lowest gear necessary move the vehicle. The extreme gear (1st low) intended for vehicular speed control and not for torque multiplication.
