workplace factors such as sound must have the minimum impact on the operators of combine harvester, so that they can guide and control many functions of the combine. in this study, some factors affecting the noise generated by two combine harvesters john deere 1055 and sampo 3065 were evaluated. research factors were engine speed, gear ratios, type of operation and microphone distance. the resu...

ABSTRACT- Noise is considered as one of the most debilitating conditions in farming operations. In this study, a number of factors affecting the noise generated by Sampo 3065 combine harvesters were evaluated. Factors were engine speed and gear ratio for combines with and without original cabins. A factorial experiment arranged as a completely randomized design with four replicates was used. Re...

one of the best applications of automated navigation systems is the use of automatic steering systems in agricultural vehicles. in this research, a machine vision algorithm was designed, based on image acquisition from a camera mounted on front of acombine harvester cab fordetection of its forward path. after filtration and optimization of the image, hough transform was utilized for extracting ...

Researchers around the world have focused on autonomous agriculture with systems encompassing greenhouse, orchard, field, and other applications. Research has shown the potential and ability of the technology to allow a vehicle or selection of vehicles to follow a specified task. In this study, one aspect of the problem, that of operating a tractor−cart combination in conjunction with a small−g...

Grain loss sensor is an important monitoring module to realize the intelligent automatic control in combine harvester. Polyvinylidene fluoride piezoelectricity film has been one of the most widely used macromolecule materials at present. Based on its piezoelectric effect, in this paper, a grain loss monitoring system for combine harvester by using the PVDF sensor was designed. The system is com...
