In this work emphasis has been given to compare the effect of vibrations on driver’s seat of tractor while working with implements during tillage and while working without implements. The experiment was conducted in the fields of Punjab (India). During the experiment, first time the tractor was made to move without implements and second time tractor was moving with chisel plough (tillage implement). Both times real time vibration data of driver’s seat was collected with three-axis accelerometer and it was observed that when tractor was moving without implements the vibration amplitude was highest in vertical direction Z as compared to transverse direction Y and horizontal direction X. But when the tractor was moving in the fields with tillage implement (chisel plough) the vibration amplitude was high in transverse direction Y relative to horizontal direction X and vertical direction Z. Key Words - Tractor, vibration, tillage implements, accelerometer. *Author for Correspondence 1. INTRODUCTION Tractors are used worldwide as agriculture tools. As tractors have to work on rough surfaces specifically during tillage so high amplitude vibrations travel to the operators seat. These vibrations are harmful to the operators and drivers feel uncomfortable with unwanted vibrations. Mechanical structures may also fail due to vibrations and reduce performance of equipment and machinery. Therefore, it becomes necessary to reduce the vibrations to compensate the undesirable vibration effects in tractors. Only tires give flexibility and absorb some vibrations. That’s why vibrations in tractors are of high amplitude [1, 2 and 3]. The road surface is the major factor for vibrations in the tractors. Effect of vibrations on human body depends upon magnitude, frequency and direction of vibrations [4]. During soil tillage operations higher vibration levels are YMER || ISSN : 0044-0477 VOLUME 20 : ISSUE 11 (Nov) - 2021 http://ymerdigital.com Page No:403
