Abstract:
The soil and topography of Bangladesh are distinct from other countries. As a result, not all
imported machine models work effectively here. Bangladesh needs to develop combine
harvesters that are technically, environmentally, and economically viable. Thus, a research
platform for locally acceptable combine harvesters was established by comparing the technoeconomic performance of three imported harvesters in haor districts. The Chinese (4LZ-0.6),
Sifang (4LZ-1.5), and Zoomlion (4LZT-4.0ZD) models with a cutting width of 1000, 1500, and
2000 mm, respectively, were employed in this study. The harvesting capacity, fuel consumption,
harvesting loss, minimum suitable plot area, ground pressure, business viability, transportation,
and operator comfortless were considered to recommend a suitable machine. Based on the result,
Zoomlion model whole feed combine harvester is excellent for harvesting in the haor area in the
bigger sizes plot, while a head width of 1500mm for smaller plots. While a small combine's cost
is incredibly low, farmers have refused to adopt the equipment since their businesses have failed
because of its restricted harvesting capacity and high component failure rate. The machinery
must be transportable in a conventional truck due to the remote road conditions (truck width
2000 mm). As a result, local roadways can accommodate whole feed combine harvesters with an
1800 mm width. In haor regions, 24 kNm-2 ground pressure and 300 mm ground clearance
functioned effectively. The adjustment of the harvester machine is extremely subtle, resulting in
strong vibrations in a single cylinder engine, causing parts to fail prematurely and the driver to
be unable to operate the machine comfortably for extended periods of time. As a result, fourcylinder engines outperform one-cylinder engines in popularity. Access to machine components
is critical, as is the presence of a grain tank for simple supply |
