DESIGN AND MANUFACTURING OF TRANSMISSION SYSTEM FOR SELF-PROPELLED ONION HARVESTER

Agricultural vehicles work under a variety of conditions and maximum work-rate and Minimum fuel consumption is dependent on selecting the correct engine speed, transmission ratio, and implement width and depth. Although the well-known technique of "gear up, throttle down" produces fuel savings, particularly at part load, a tractor with a fully integrated engine-transmission-implement control system would have a dynamic response to varying loads to achieve the maximum work-rate for the minimum fuel consumption under all conditions. This report considers transmissions that could be used on an integrated control tractor and discusses the transmission requirements and how well the various types meet them. INTRODUCTION
