Comments

Header unit

Reel successfully gathered the standing and leaning crops.

Cutting unit

The cutter bar moves smoothly and successfully cuts the crop. Any uncut plant was not found.

Conveying unit

Cut crop conveyed to the threshing drum by conveyer belt. Overfeeding clogged the conveying unit.

Threshing unit

Grains were separated from the panicle successfully.

Cleaning unit

A cyclone separator cleaned grains. The cleaning was so good.

Gear Changing

The gear-changing mechanism is straightforward.

Power transmission system

The gear mechanism is easy for the operators.

Vibration and noise

The vibration characteristics of various structures are notably pronounced, particularly at the header component of the harvester, where factors such as load and road surface conditions contribute to its robust vibration. This heightened vibration, and accompanying noise from the cutting components adversely affect the operator’s comfort and the overall lifespan of the equipment frames. Additionally, the continuous vibration led to the loosening of nuts and bolts. The machine’s vibrations significantly impacted the operator’s comfort. During the grain delivery, the lifting cylinder exhibited noticeable vibrations while unloading grains. These findings underscore the importance of addressing and mitigating vibration-related issues for enhanced operational efficiency and operator comfort.

Turning

It is easy to turn the harvester, especially right turning.

Harvesting speed

The machine operates at a slightly reduced speed, and attempts to increase this speed result in clogging issues in the conveyor belt’s feeding mechanism. Conversely, running the machine at excessively high speeds leads to pronounced vibration at the front header, which impacts the reel’s movement. This heightened vibration and reel instability ultimately increase paddy loss at the header. Striking the right balance in operational speed is crucial for maintaining smooth and efficient harvesting processes.
