“…Nowadays, workers migrate to cities or abroad to engage in more remunerative employment, particularly in the garments and construction sectors and high labor wages in peak harvesting season (15). Developed countries like South and Southeast Asia are using automatic combine harvester for harvesting cereal grains, and as a medium grade technology, and many developing countries are using a reaper for harvesting rice to minimizing production cost and are thereby, making agricultural production economical (1). Mechanical harvesting machinery must be introduced to reduce crop losses and raise cropping intensity.…”

“…It simplifies and gets rid of labor-intensive processes, makes up for manpower shortages, and increases productivity (12). Suitable technology, particularly harvesting machinery, is urgently needed to develop and implement for agricultural mechanization in order to improve productivity with less drudgery and more efficiency (1). The labor demand for rice harvesting reaches its highest between 170-200 man-hours per hectare when employing sickles.…”

Mechanized paddy harvesting is currently limited in Bangladesh, but the pace of mechanization is increasing. Harvesting must be done on time to minimize losses and timely harvesting depends on the availability of harvesting machinery. The aim of this study was to find out the state of mechanized paddy harvesting technologies in Sylhet region over the last five years. The study was conducted in all upazilas under the Sylhet region to compare mechanized and manual paddy harvesting technologies. Structured questionnaire was used to collect data. The survey revealed the changes in mechanization status in 2022 compared to the previous four years. In the study area, the average paddy cultivable area was 0.91 million hectares. The pace of mechanized harvesting in Sylhet, Sunamganj, Habiganj, and Moulvibazar district were 31.49%, 24.41%, 19.59%, and 15.95%, respectively. On the basis of the provided data, from 2018 to 2022 the number of harvesting machines increased from 547 to 1852. The manual method, combine harvester, and reaper were used to harvest 76.20%, 21.90%, and 1.90% of the total projected area respectively in 2021-2022. The study revealed that combine harvester covered around 87.47% area than reaper. In 2022, among the 40 upazilas, the most machines were found at Nabiganj upazila in Habiganj district =106, and the fewest machines were found at Barlekha upazila in Moulvibazar district =10. The trend of manual paddy harvesting has declined in Sylhet region due to the increase in the number of harvesting machines. So, harvesting machineries are needed in this region to update paddy harvesting mechanization status.

“…In this case, harvesting is complicated with dead plants and requires specialization of equipment for their preliminary rise and delivery for cutting [5]. Therefore, the development of such a machinery is aimed both at improving the design of devices [6,7,8], and at increasing their efficiency [9,10,11].…”

Justification of the parameters of the floating crop lifter when mowing crops

When harvesting dead plants the reapers and mowers are equipped with crop lifters, which lift and feed dead plants (stems) to the cutter. High-quality work of well-known crop lifters is not always ensured due to poor following the relief of the mowed area. Therefore, the aim of the study was to improve the design of a stem lifter of a mower or header and to justify its parameters experimentally. The floating crop lifter is proposed for the use. It consists of a runner pivotally attached to the base, and the base is attached to the finger bar of the header cutter. A lifting pen is rigidly fixed to the runner at an angle of 35°. Between the base of the runner and the lifting pen, a gas strut with excess pressure is installed. The manufactured laboratory unit made it possible to carry out experimental studies. Implementation of the experimental design and computer processing of the obtained results made it possible to justify the optimal values of a number of indicators of the design of the crop lifter. The smallest material losses (less than 1%) were observed at coded values of the factors: X1 = 0...0.5; X2 = -0.25...0.25; X3 = -0.5...0. This corresponded to the natural values of the studied factors: runner length l = 450-500 mm; the load of the gas strut P = 45-55 N; operating speed of the unit υ = 1.2-1.6 m/s. The obtained exponential dependence on the parabolic function of these factors adequately describes the experimental results.
