To solve the problems of congestion and increased power consumption wheat combine harvesters (WCHs) caused by excessive feed rate, this paper proposes a method to reduce rate decreasing length stalk designs double-cutterbar header (DCH). Using threshing test bench taking stalk, speed tangential rotor as influencing factors conveying time index, influence different parameters on performance was ...

Cereal straw is a biomaterial with great potential: about 144 million tons of biomass are grown annually in Europe. For any use (fertilizer, biofuel, etc.), efficient chopping technology, i.e., the reliable and operation mobile or stationary choppers, key factor for further success. Since most chopped at harvest time, subject study wear combine’s knives. Six blades different materials designs w...

grain loss monitors are installed on combine harvester and make it possible to measure grain loss on different parts of the combine. the instrument permits the operator to adjust a proper ground speed to keep grain loss within an acceptable range. in this study a loss monitoring system was implemented to measure grain losses continuously on straw walker and sieves. two grain loss monitors (kee ...

farm machinery managers often need to make complex economic decisions on machinery replacement. repair and maintenance costs can have significant impacts on this economic decision. the farm manager must be able to predict farm machinery repair and maintenance costs. this study aimed to identify a regression model that can adequately represent the repair and maintenance costs in terms of machine...

Combine harvesters have a very important task in grain crop harvesting. Combine harvesters must fulfil lot of technological requirements regarding the field conditions, crop type, as well as the quality performance and optimal costs. The problem is that it is the main harvesting technology of cereals in the world and it has seasonal character of work, which has to be done in a relatively short ...

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...
