Claas combine harvester

Types of CLAAS combine harvesters

The CLAAS combine harvester is a modern agricultural machine that harvests grain from all types of cereal crops. It can also be used to harvest cash crops such as soybean, pea, sunflower, and maize. The main steps CLAAS combines perform during harvesting include cutting down the crops, threshing the grains, winnowing to separate the grains from other debris, and finally, loading the grains onto a truck or container.

The CLAAS combine harvester can be divided into the following types based on functionality:

• Classical Combine:

  The classical CLAAS combine harvester features traditional three-step threshing. It consists of a cylinder and concave that separate the grains from the straw. The classical combines are suitable for various crops and field conditions but may be less efficient in straw processing than rotary models.

• Rotary Combine:

  Rotary combines are based on the principle of rotary threshers. They feature cylindrical rotors with threshing sections rotating inside a concave. The rotary combines provide substantial space for separating grains from straw by easily passing through the concave. This method enhances the extraction of grains from the straw while simultaneously improving straw decomposition in the field. Such CLAAS combine harvesters are particularly well-suited for handling crops with high straw content, like rice and wheat.

• Hybrid Combine:

  Hybrid combines incorporate features of classical and rotary threshing systems. They provide flexibility in harvesting various crops and optimizing straw management according to specific field requirements.

• Mega Combine:

  The mega combine harvester is a larger and more high-capacity model within the CLAAS combine range. It is suitable for large-scale farming operations and features high performance, advanced technologies, and efficient grain processing capabilities. The mega combines also include self-propelled models, which are large, autonomous machines that can harvest their own crops.

Specifications

The CLAAS combine harvester features many essential specifications, including engine power, cutting width, tank size, overall dimensions, and harvesting technology.

• Tank Size: The tank size ranges from 35 to 140 m3 (from 35 to 140 tons). A larger tank size reduces the frequency of refilling during harvesting, thus improving overall harvesting efficiency.
• Overall Dimensions: The length and width are about 12.52×5.49 m. The appropriate size makes the combine harvester adapt well to different field operations and road transportation.
• Harvesting Technology: The combine harvesters are equipped with different harvesting technologies, such as a reel cutter, chain auger, and accelerated separation system. They can ensure the highest quality and efficient harvesting and separation processes.

Maintenance

Combine harvesters need regular maintenance to make sure they work well and keep them in good condition as best as they can for a long time. The following are some typical maintenance tips.

• Cleaning: The first step is to thoroughly clean the machine, including the outside and interior. This helps remove food residue, dust, and other pollutants and prevent potential blockages and fires.
• Lubrication: Nourishment is indispensable; applying lubricant to pivotal parts and transmission components of the combine harvester can help lower friction and wear so that the parts will move smoothly.
• Replacement of filters: The air and oil filters should be checked and replaced regularly by the CLAAS filter replacement schedule. This ensures that the engine receives clean air and oil, reducing the risk of pollution and damage.
• Tire maintenance: Keep the tires of the combine harvester at the proper pressure and remove the foreign body from the tires to avoid any damage, such as abrasion and puncture.
• Maintenance of electrical systems: The electrical system must be maintained, comprising batteries, circuits, and electronic components. Ensure the connection is firm, clean, and free of corrosion, and check the functioning of the lighting and signaling systems.
• Regular system checks: Check various systems of the combine harvester, such as the transmission system, separation system, threshing system, etc. Follow the operating instructions to inspect and adjust the relevant parts to ensure their proper functioning and harvesting efficiency.
• Maintenance of clas combine harverster parts: CLAAS combine parts require the most attention. Examine the state of wear and tear on the cutting devices, separating devices, threshing cylinders, and other components. Clean the residue, lubricate it, and repair or replace the damaged parts timely.

Applications of Claas Combine Harvesters

The utilization of agricultural machine harvesters like the Claas combine harvester can be divided into four main categories based on grain type, terrain, and harvest requirements.

• Grain Type: Different combine models are suited for specific grains. For instance, corn combines like the Claas Corn combine harvester are designed for harvesting corn efficiently. Similarly, rice specializes in utilizing a rice-specific combine, such as the Claas rice combine harvester. By employing the appropriate combine for each grain type, farmers can optimize their harvest and maintain the quality of the crops.
• Terrain: The selection of combine harvesters can also depend on the terrain where the crops are grown. For flat or gently sloping fields, conventional combines are commonly used. On the other hand, regions with hilly or mountainous terrain may require specially designed combines equipped with traction systems and headers that can navigate challenging landscapes effectively.
• Harvest Requirements: In addition to considering the grain type and terrain, the harvest requirements also play a significant role in determining the suitable combine harvester. Some combines are equipped with features that allow for the separation of valuable herbs from grains, such as those used in herbal farming. These specialized combines offer enhanced separation capabilities, ensuring minimal contamination and preserving the integrity of the herbs. By choosing combines that align with specific harvest requirements, farmers can achieve higher productivity and better-quality yields.

How to choose CLAAS combine harvesters

Choosing the right combine harvester requires a detailed study and understanding of some aspects.

• Farm requirement analysis

  Assess the type of crops harvested, total farmland, and harvest volume on the farm. Determine the needed harvesting width, productivity, and configuration of the machine. Also, consider if there is a special requirement for harvesting quality, such as maturity, cleanliness, and grading. Finally, evaluate the existing infrastructure, such as access roads and storage facilities, to ensure the harvested crop can be handled immediately.

• CLAAS combine harvesters series

  A predominant model of the field is the focus. For instance, the *Evolution Combine CLAAS Ackord 470* is mainly suitable for small-sized towns and crops such as wheat, corn, rice, soybeans, and sunflowers. The DAWN 4500 CLAAS Combine Harvester parts model is particularly suitable for small towns with tram lines and works effectively in wheat and paddy crops. In contrast, the hybrid model, such as Revolution Combine CLAAS 15 HP, is suitable for large fruit cultivation areas and can harvest various types of crops.

• Other crucial features

  The harvester should have a powerful engine and efficient fuel system for high productivity. Advanced separation and threshing systems enhance crop recovery and reduce grain damage. Grain processing systems, such as cleaning, grading, and binning, directly impact the quality and storage of harvested crops. A well-designed and ergonomic operator's cabin can improve operator comfort and productivity.

• Maintenance and support

  Consider the machine's maintenance and spare parts accessibility. Choose machines with easily replaceable parts and established maintenance networks. Evaluate the resale value and potential depreciation of the harvesters.

ClaS Combine Harvester Q & A

Q: How does a combine harvester work?

A: A combine harvester performs three major tasks - cutting, threshing and winnowing. It cuts the crops from the field using a cutter bar. The reaper then moves the cut crops to the machine's drum for the next process. The drum threshed the crops to separate the grains from the straw. Finally, the fan of the combine machine blows the lighter straw back into the field while the heavier grains fall into the storage bin.

Q: What are the types of combine harvesters?

A: There are two main types of combine harvesters - the front-reaper type and the rear-reaper type combines. The front-reaper type is more suitable for harvesting wheat, rice, and soybeans, while the rear-reaper type is suitable for crops of significant height like corn and sorghum.

Q: What are some advantages of using a combine harvester?

A: Using a combine harvester increases the efficiency of crop harvesting by 10-20 times as it combines three processes into one. It also improves the quality of harvested crops by reducing manual handling and the risk of damage to the grains. Lastly, combine harvesters save labor costs and reduce the need for manual workforce during harvest seasons.
