Unimark machines are controlled by our 11-programme line/gap computer. The unit gives control to manual, semi- or fully-automatic line laying. The built-in totaliser gives production rates. With 4-position joystick control, line patterns can be altered without stopping the vehicle. Tandem gun operation is also available. Unimark operates on policy of continual research and development, therefore specifications can change without notice. The images are indicative.
