Study on the process of unloading grain harvesters at the end of the field
Abstract. The paper analyses the cases of unloading harvester hoppers at the end of the field. A passive experiment was carried out in two agricultural farms
while harvesting wheat and rice, and the times that affect the unloading of the grain hopper have been measured when the harvester moves to the end of the
field to unload its hopper. In chronometering the operations it has been established that 63% of the time for unloading grain hoppers at the end of the field is
used for auxiliary operations and only 37% of the time is related to proper unloading of the grain hopper. It has been found that the time for moving the harvester
to the vehicle at the end of the field has longer duration (t = 127.72 s) than the time when the harvester goes back to the strip of land to continue harvesting (t = 1 7
80.36 s)
