Types of Asia harvesters

As the agricultural sector continues to develop, many farmers are now looking for efficient ways to harvest their crops. This is mostly because of the constant need to improve productivity and lower labor costs. Agricultural Asia harvesters are specially designed for different types of crops and farming practices.

• Combine Harvester: This is a machine that combines different harvesting procedures into a single unit. It uses a reaper, thresher, and stripper to harvest and process grains like rice, wheat, rye, oats, and barley. Some advanced models can also perform other tasks such as weeding, loosening earth around the crops, and field drying.
• Mowers/Swather: They can either be separate machines or parts of a combine harvester. They cut crops close to the ground. While mowers use blades for the cutting process, the swathers rely on cradles and sickles. Typically, swathers cut the crops and lay them in straight rows known as windrows. Some advanced swathers can also dry and thresh crops.
• Specialized Harvesters: These are agricultural machines manufactured to meet specific crop harvesting needs. They are mostly designed for tree fruits, nuts, vegetables, and specialized field crops like sugar cane and cotton.
• Automated Harvesting Systems: Some developed countries in the world have started using machines that are operated by artificial intelligence. These machines have cameras and sensors that help identify and pick ripe crops. They are mostly useful in large scale agriculture. An example of this automated harvesting system is the automated lettuce harvester.
• Semi-Automated Harvesting Systems: Semi-automated harvesters can also be fitted to the harvesting machines made for different crops. They often include assistance for tasks like cutting, feeding, and basic sorting. The semi-automated system will require manual assistance for installation and other functions.
• Robotic Harvesters: These are the machines that have sensors and cameras to identify and collect ripe fruits and vegetables. They excel in precision and can reduce the need for manual labor.

Specification and Maintenance of Asia Harvester

Specifications of grain harvesters from Asia vary according to the models. Here are some basic specs corresponding with the different types of Asia harvesters.

• Capacity: This refers to the amount of grains the Asia harvester can process per hour. For instance, a small-hopper Asia harvester can have a capacity of 500-1000 kg per hour, while an automatic model might have a capacity of about 2000-4000 kg per hour with continuous operation.
• Power Source: Asia harvesters have different power sources. A small or drawn harvester may rely on manual pedaling or an animal's energy, while an advanced automatic Asia harvester may use a diesel-powered engine or tractor attachment.
• Dimensions: An Asia harvester's dimensions, comprising its length, width, and height, determine its size and maneuverability. The measurements will vary according to the type of Asia harvester and its model. A small mechanical harvester may measure about 1.5-2 meters in length and up to about 2 meters in width. Larger harvesters, such as the self-propelled ones, will have larger dimensions. For instance, the length may be as high as 10 meters, and the width could be 4-5 meters.
• Weight: Modern Asia harvesters with automated features are heavy machines. The weight of the Asia harvester varies according to the model and type. A small powered Asia harvester can weigh about 200-500 kg. Larger, more mechanized harvesters can weigh several tons, often between 5000 to 15000 kg.
• Cutting Width: It is the widest area from which grains can be cut in a single pass. The cutting width of the Asia harvester varies with the machine's model and type. A small harvester may have a cutting width of about .8 to 1.5 meters. Larger harvesters, such as the self-propelled ones, have a cutting width of about 4 to 10 meters.

Maintenance

Regular maintenance will ensure the Asia harvester's long life, efficiency, and reliability. It will also minimize breakdowns and downtime during crucial harvest periods. Here are some basic maintenances tips corresponding to the type of harvester.

• Small Mechanical Harvesters: Cleaning the machine parts daily after use will prevent the accumulation of debris and residues. Lubricating moving parts, such as chains, bearings, and rollers will reduce wear and tear and enable smooth operation. Operators should check the working parts, such as belts, blades, and bearings, to see if there is any unusual noise or slippage, and replace them as necessary. The air filters and fuel filters should be cleaned or replaced at regular intervals.
• Motorized Harvesters: Motorized Asia harvesters, both small and large, should have their engine oil changed and filters replaced according to the manufacturer's schedule. The cooling system, including coolant levels and radiators, should be checked frequently. Fuel system components like lines, injectors, and pumps should be inspected for leaks or clogs. Electronic systems, sensors, and wiring should be checked periodically and calibrated as necessary.
• Self-propelled Harvesters: Self-propelled Asia harvesters have complicated mechanisms that may require professional help. Nonetheless, some basic maintenance tips can be done regularly. The entire harvester should be washed and cleaned thoroughly to remove dust and residual grains and prevent contamination. Lubrication of moving parts should be done as per the manufacturer's instructions. Fasteners and bolts should be checked to ensure proper tensioning and fastening. The tracks and tires of the harvester should be inspected for wear and tear, as well as any damage.
