Klaas combines - review of the Jaguar model line

The use of combine harvesters in agriculture is a vital necessity. This is a multifunctional machine that can simultaneously perform a large number of operations. If necessary, combine harvesters are equipped with additional equipment that expands the functional potential of specialized equipment. There is a wide range of these products on the market.

Harvesters Klaas Jaguar

The Klaas company has a long history. This is a family business that was founded in 1913. Today, the company has a wide presence throughout the world and is positioned as one of the best manufacturers of agricultural machinery.

The Klaas Jaguar series of combine harvesters was first presented to the world public back in 1973. The need to use multifunctional equipment arose due to the rapid growth of areas with corn plantations.

The Claas company has managed to create a self-propelled harvester capable of performing a large number of options simultaneously. As a result, farmers could optimize the entire work process and increase production volume.

Subsequently, the Jaguar line was updated eight times. The latest metamorphoses were implemented in 2007. Regular restyling allowed us to present consumers with a product of the highest quality that meets all necessary requirements and has high performance.

Peculiarities

A characteristic feature of the combines presented in this model range is a unique drive circuit. Despite the extreme design simplicity, the implementation of this method contributed to an increase in the rated power of the power plant component. The designers managed to increase the power potential from 310 hp. up to 481 hp

The essence of the original drive concept is that the combine's chopping mechanisms are driven directly through the crankshaft of the power plant component. As a result, the overall throughput tends to increase.

The presence of an electronic engine control unit, which makes the operation of the power plant more stable and predictable, deserves special attention. Also noteworthy is the installation of a continuous moisture measurement system and the use of new grinding drums.

Advantages and disadvantages

All combines presented in this model line are distinguished by simple and convenient operation. This can be achieved thanks to the presence of a multifunctional handle, which is responsible for adjusting the operation of the machine.

Installing a special information system allows you to monitor the progress of all additional options. With a moderate level of fuel consumption, the component unit produces record power, which indicates the high performance of the machine.

The advantages of Claas Jaguar combines also include:

• unique drive system;
• special shape of knives;
• high maintainability;
• the presence of a target management system;
• use of a continuous humidity measurement system;
• option to adjust the throwing power of the output accelerator.

In addition, such machines are equipped with a large-sized crusher of increased power, the diameter of the rolls is 250 mm. The main disadvantage of this variation of agricultural machinery is the high level of price indicators.

Review of popular models

Production of Jaguar 800 series combines started in 1993. The 900 models were delivered to the assembly line in 1999. The potential power of the power plant of Claas Jaguar 800 series combines varies between 310-481 hp. More modern 900 models are equipped with a 605-horsepower engine.

Jaguar 840

The Jaguar 840 combine harvester is equipped with a dynamic cooling system. The fan rotation speed is adjusted depending on the temperature of the incoming air flows and the oil pressure. In this context, we can talk about the efficiency of engine power, which will subsequently be used for the header. The centralized lubrication system facilitates machine maintenance. An optimal supply of cooling air is ensured by the location of the direct drives behind the steering axle.

Jaguar 850

This model has a spacious two-seater cabin, which accommodates not only the combine operator, but also his shift worker. The internal filling is made taking into account all ergonomic requirements. The cabin offers a good overview, which allows you to control the progress of the work process. The chopping drum has a total length equivalent to 750 mm. There are knives located on it in one plane, which ensure cutting of crops. The combine operator can carry out the knife sharpening procedure directly from the cab.

Jaguar 830

Transportation of the cut plant mass is carried out straight through the entire machine. This is made possible thanks to the Jaguar Green Eye system.

Maximum efficiency in responding to changing harvesting conditions is ensured thanks to the system of stepless cutting length control. This combine can reach speeds of up to 40 km/h. Optimal traction force is ensured by high gearing.

Jaguar 860

A characteristic feature of the Jaguar 860 combine is its rich equipment. The model is equipped with a special electric sharpening device, an on-board computer, a grain processor, an air conditioning system and a special hectare counter. The basic package includes a six-row header and a pick-up. Drives and safety couplings are designed to withstand long-term operation in harsh conditions. Model characteristics:

Jaguar 870

The Klaas Jaguar 870 can reach speeds of up to 40 km/h. The combine is characterized by high productivity, reliability and ease of use. The machine is used to solve problems related to silo harvesting. The presence of the Rock Stop system provides reliable protection of the structure from stones when harvesting on rocky soils.

To measure the lifting speed, special sensors are installed on the front feed roller. When a large stone hits the roller, it automatically rises and the system is blocked. This provides protection against various mechanical damage.

Jaguar 900

The Klaas Jaguar 900 is equipped with a 605-horsepower unit, as a result of which we can talk about a high level of performance of the unit. The model is equipped with an all-wheel drive system with the ability to connect traction force. The simplified maintenance work of such a combine contributes to the fact that its popularity among farmers tends to grow.

Specifications:

Jaguar 950

The Jaguar 950 combine has a wide range of applications. It is used for harvesting corn, grain and willow crops. The model has a spacious, comfortable cabin with all-round visibility. Minimizing the weight of the chassis has a positive effect on increasing the speed characteristics of the machine. As a result, the productivity of the combine is significantly increased.

To effectively use silage preservatives, a special additive system Actisiler 20 is used.

Technical and economic indicators

Purpose. The self-propelled forage harvester Jaguar 870 is designed for mowing green grass and picking up dried grass, mowing corn with simultaneous chopping and loading the crushed mass into vehicles.

Construction . Consists of a self-propelled shredder and a PU 300HD pick-up. The shredder includes: a frame, a motor-power unit, a cabin, axles of driving and steered wheels, a hydrostatic drive of running wheels, a chopping apparatus with a V-shaped arrangement of knives with offset, a feeding apparatus with 4 rollers, a metal detector and a stone detector, an accelerator mass, silo pipeline, installation for adding preservatives, drive of working parts, control mechanisms and electrical and hydraulic equipment. The drive of the pick-up and feed rollers is equipped with electro-hydraulic reverse. The combine is controlled using a control panel, a multifunction lever and a monitor from the operator’s workplace.

Agrotechnical assessment. Tests were carried out on the selection of double windrows of dried plant mass with simultaneous loading into vehicles. The cutting length of particles up to 30 mm in size was 62.2% with a set length of 34.0 mm, loss 0.1%.

Reliability. The combine's operating time was 264 hours. 2 refusals were noted. MTBF is 132 hours, availability factor is 0.992. Without taking into account the rejection of natural stones, the availability factor is 1.0.
