In order to quantify tractor driver Whole-Body Vibration (WBV) induced by some of the agricultural operations, the ISO 2631 standard was utilized. Detailed methodology of the calculation of the WBV evaluating indices using the time-domain acceleration data analysis was presented. According to the results of the study, typical weighted root mean square (WRMS) value of the Z-axis vibration was mo...

Harvesting rain-fed chickpeas (Cicer arietinum L.) from fallow fields in developing countries is currently a manual process performed by laborers in a tedious manner at a low level of efficiency. A tractor-pulled harvester was built in which a chain conveyor transfer harvested material. A tractor-mounted harvester was then redesigned, which incorporated a modified stripper header to detach pods...

In agriculture, a typical task is to do a coverage operation for a field. Coverage path planning algorithms can be used to create the path for a vehicle. In case of an autonomous agricultural vehicle, the path is provided to the guidance or navigation system that steers the vehicle. In this paper, a four wheel steered tractor is used in autonomous sowing operation. The full size tractor is equi...

Finger millet crop is important minor millet, which can serve as both food and fodder. Manual harvesting of finger involves earhead stalk separately labor intensive. Hence, the study aimed to design develop a harvester for remove drudgery in achieve low cost harvesting. The machine parameters influencing millets were identified most prominent variety CO (Ra) 14 millet. A prototype was developed...
