      abstract = {When tillage operation is carry out using tilling plough the soil is disturbed. The level of disturbed soil is determined by profilelometer. An automated instrument was developed to determine the profile level of the rigid form by the operation. The soil tilling tillage profile meter consists of aluminum frame, two ultrasonic range finder to determine both horizontal and vertical distance, a dc motor and bidirectional motor control, microcontroller unit, storing medium and liquid crystal display unit. The frame is 130 cm x 30 cm x 60 cm and carrier and motor with two pulleys were attached to frame. The pulleys were 100 cm apart. The carrier conveying the two ultrasonic sensors: one pointing vertically and the second place horizontally with obstruction on side 100 cm apart. As the motor is toward the obstruction distance increases and is backward it reduces to zero. The values of measured two distances were store on the memory card. The time the operation can be vary from 20 s up to 60 s. The accuracy of the finder used for measurement is ? 1 cm. The resolution is 1 cm. The Soil Tilling Tillage Operation Profile meter has maximum depth value of 150 cm and with 90 cm wide.},
