There are various designs of tools and equipment used for harvesting the crops and threshing it separately. Sickles, hand tools and reapers for grain crops and diggers for tuber crops and rhizomes, operated with different power sources are used. Combine harvesters, both tractor mounted and self-propelled, are being very widely used for different grain crops. Functional requirements and principl...

The combine harvester (CH) is one of the most important machines with powerful engine used in agricultural sector. It consumes significant amounts diesel fuel and harms ambient air by releasing emissions. This study examines telematics data CHs (models axial threshing apparatus) collected between 2017 2020. time spent various operating modes CH, consumption, negative impact on (expressed global...

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...

The use of modern tools or machines can save time and reduce the number workers compared to traditional agricultural systems. history world agriculture has increased from accompanied by technological developments. As for one advanced in rice harvesting process that is currently popular recent years, Combine harvester. harvester a machine cut grain, thresh, clean grain. Indrapuri Sub-district su...

Combine harvesters are the source a large amount of noise in agriculture. Depending on different working conditions, such machines can have significant effect hearing condition drivers. Therefore, it is highly important to study signals caused by these and find solutions for reducing produced noise. The present was carried out order obtain fractal dimension (FD) Sampo John Deere combine operati...

in this research, the effects of combine renovation as a mechanic harvest evaluation index of wheat were studied. results show that this renovation has decreased wheat losses by 1368 thousand tons which worth 2462400 million rials. two scenarios were investigated. first, under real condition with earmark of government subsidies for purchasing machines, was studied at both guaranteed and world p...
