| The objective of the study was determination the release of seeds, caused by а lateral mechanical impact for feeding sesame stems into harvester in order to define the conditions for reducing losses. An experimental unit for simulating mentioned impact has been created. The percentage of releasing seeds depending on acceleration and the height of application point of the impact on single stem has been determined. It was found that the feeding of sesame stem into harvester can be achieved by a lateral impact with acceleration up to 0.5 m.s-2 and speed up to 1.05 m.s-1, if the application point has height 0.6 m from the soil surface. This impact causes up to 5% release of seeds from hybrid 27 when their moisture is 6.2%. The percentage of the seeds releasing... |

| The machinery stock, fuel consumption and work time are crucial economic factors for the profit potential in the arable farming sector. The influence of five soil tillage systems (two conventional tillage systems and three conservation tillage systems) and two tractor sizes (92 kW-tractor and 59 kW-tractor) on work time, fuel and energy consumption was measured in the semi-arid region in Austria. The tractors were equipped with a high-performance flow meter and a radar sensor to measure the fuel consumption (L h-1) and working speed (km h-1). The conventional tillage with mouldboard plough has the highest working time and fuel consumption rate. The replacement of plough with a cultivator, reduces the work time and fuel consumption for soil tillage as... |

| The objective of the study is giving proof of a technological scheme and the basic parameters of a new device for feeding sesame plants into the harvesting machine at reduced seed scattering. The kinematics of the point of contact between the plant and a finger of the feeder conveyor has been investigated. The laws for the displacement and the velocitty of that point have been synthesized. They have been used to determine the displacement of the contact point on the stem, the kinematic factor of the conveyors, and also to calculate the position of the knife to the point of initial contact of fingers with the plant. The operation of the new device requires adjusting the longitudinal slope of the conveyors from 0° to 10° and their kinematic factor of 1.1 to... |

| The main purpose of this study at the first phase was to rank all rice transplanters used in Guilan Province by relevant experts in the area from technical, social, and economic aspects. After the most appropriate type was identified, the technical skillfulness of operators to use this specific type was assessed in the second phase. To this end, the analytic hierarchy process (AHP) was applied and the opinions of experts for exploring the most appropriate rice transplanter based on ergonomics, economic advantage, reliability, field capacity, ease of use, ease of repairs and access to spare parts, compatibility with plot conditions, planting density range, compatibility with different soil conditions and planting quality perspective was assessed. To... |

| Shortage of labor during the harvest season is one of the problematic situations for farmers in the Malaysian paddy fields. Thus, combine harvester has been utilized massively in Malaysian paddy field for the purpose of assisting the farmers to overcome the problems. Majority use of combine harvesters in the country was provided by the state farmers’ organization that offers custom operators to be hired by the farmers during harvesting seasons. A case study was conducted to identify and rank the factors that affect farmers’ current satisfactions with mechanized harvesting using combine harvesters that offered by custom operators. A group of farmers comprising of 336 respondents at rice granaries in Tanjung Karang district, Selangor, Malaysiawas chosen... |
