A simple electronic device, using ultrasonic and Arduino technique, is designed and created as traditional method for measuring and evaluation a process for no-till opener under down force system. The design connected with prototype of helical spring-loaded for un-parallel linkage was verified in laboratory and field conditions. To evaluate the prototype performance, field experiments carried out in sandy loam soil with two different moisture contents of 18% and 28% w.b. at Tractor and Farm Machinery Test and Research Station in Alexandria, Governorate. The results of helical springs were evaluated and calibrated in laboratory. The developed device was experimentally investigated as a function of change in two tractor speeds of 3.0 and 4.0 km/h and three different helical wires diameter of 3.5; 4.5 and 5.5mm. The results indicated that the used electronic device is suitable for estimating the down force related to operating time.
