company news about Classification of tractors

Tractors can be divided into two categories according to the use of agricultural tractors and industrial tractors. Generally speaking, agricultural tractors with a variety of farm equipment, mostly in the softer and flatter field soil, with a more stable speed and rated load work. Industrial tractor with special work device, mostly in the more complex natural soil, to change the speed and alternating impact large load work, and thus the industrial tractor characteristics have some special requirements: the work process can be increased with the load and reduce the driving speed, in order to play the maximum traction or thrust; have a higher backward speed and its corresponding change in reverse driving fast shift mechanism; have a higher The cross-country through the ability; have more power output points and greater power output capacity, etc.. Similarly, the structural strength and rigidity of industrial tractor parts also have higher requirements than agricultural tractors, some parts also need to increase some necessary protection devices, and thus the structure of industrial tractors than agricultural tractors bulky. Part of the agricultural tractor variant derived from the industrial tractor, the strength and stiffness of the parts are weaker, only for agricultural engineering work or lighter load of general engineering work.

Wheeled tractor
Tractors with more than 4 wheels (see color chart). Including two-wheel drive tractors (referred to as 4 × 2 wheel type) and more than 4 wheel drive multi-wheel drive tractors (the vast majority of 4 wheel drive, referred to as 4 × 4 wheel type). 4 × 2 wheel tractor is the production and use of the most a model. Its outstanding advantages are: good quality of work, adaptability, high degree of comprehensive utilization, light manipulation, good labor conditions. This tractor is suitable for plain and shallow hilly areas. Its weakness is poor adhesion performance, in the slope, clayey soil and wet land, sandy soil area use by certain restrictions. 4 × 4 wheeled tractor in addition to the advantages of 4 × 2 wheeled tractor, there are better traction adhesion performance and cross-country performance. This tractor in the slope, soil clinging and wet, sandy land operations, as well as in the farmland infrastructure operations than 4 × 2 wheeled with better adaptability. 4 × 4 wheeled tractor according to the structure of different can be divided into independent and variant two. The former is specially designed and manufactured, the front and rear wheels as large; the latter is in the 4 × 2 wheeled tractor based on the changes to come, generally is the front wheel small rear wheel large. Independent type than the variant has better traction attachment performance and performance, but the structure is more complex, higher production costs. Variant tractor parts used and its base type parts common degree, so that both easy to organize production, the cost is also lower.

Crawler tractor
Crawler tractor advantages are: good traction adhesion performance, unit width traction force, low ground pressure, off-road performance, good stability. In the wet, sticky land, track tractor has good performance. Small crawler tractor on the mountain, terraced and sloping land has good adaptability. But the track tractor is not suitable for transport operations, the structure is more complex, more supplies, higher manufacturing costs.

Walk-behind tractor
Small shape, flexible, suitable for small plots, terraces, vegetable fields and vegetable gardens, and because of easy to operate, easy maintenance, comprehensive use of good, low price and suitable for general farmers. Its disadvantage is: only suitable for light load operations, low productivity, operating labor intensity (see color chart). The walk-behind tractor can be divided into drive type, traction type and part-time 3 kinds. Drive type to rototilling operations, power mostly 6 to 9 kilowatts; traction type can only traction operations, power is small, generally not more than 3.7 kilowatts; dual-use type can both rototilling and traction work, comprehensive use of good performance, power mostly 3.7 to 9 kilowatts. Walk-behind tractor for the paddy iron wheel or high pattern tires can also be under the paddy work, towing trailer can also be used for transport operations. This tractor in the south of China's paddy field areas are widely used, in the northern part of the dry crop areas have also been promoted.
