With the rapid development of society and the continuous improvement of technology, agriculture has been separated from the original way facing the back of the loess, and small tractors have gradually emerged in agriculture and are widely used.Choosing a suitable small tractor will lay the foundation for the smoothness of agricultural production.So, how to buy tractors? What are the precautions for buying agricultural tractors?
What is a tractor
Agricultural tractors have three types: hand -in -handed tractor, wheel tractor, and crawler tractor; according to power, they can be divided into large, medium and small tractors.Among them, the hand -supported tractor is a small tractor with a power below 11kW (15 horsepower). It is mainly suitable for farmland operations and short -distance transportation operations in small fields. It is more common in rural areas in the south.Wheel tractors are divided into two types of belt transmission and power output shaft transmission. The belt transmission is generally a small four -wheel tractor with a power of 8.8kW ～ 14.7kW (12 horsepower ~ 20 horsepower); The medium -sized tractor is above 14.7kW (20 horsepower). With the needs of production, the power of the tractor is getting larger and larger; the wheel tractor is mainly carried out in rural areas in northern my country to conduct farmland operations or transportation operations. The use of large -scale farmland production can greatly improve production efficiency.Because the crawler can be equipped with a shovel, it is generally used in farmland basic construction and construction of water conservancy projects.Agricultural tractor power uses diesel engines.
How to buy a tractor?
1. The selection of the whole machine form
Small tractors that drive belt transmission are usually called small four -wheel tractors. In recent years, the small four -wheel tractor in the market has 11.0kW (15 horsepower) and 13.2kW (18 horsepower).14.7kW (20 horsepower) and 8.8 KW (12 horsepower) small four -wheel tractors are less in the market.There are two categories of diesel engines installed on the small four -wheel tractor. One is evaporating water -cooled diesel engines, and the other is circulating water -cooled diesel engine.Because these two types of diesel engine structures are different and parts cannot be swapped, you should choose the type of diesel engines commonly used in your area when buying tractors, which is very important for future maintenance and maintenance.
2. Choose brand -name products
Because brand -name products are recognized by the public for a long time, or by authoritative departments (such as the Agricultural Machinery Promotional License Products), their products are reliable, advanced performance, large products coverage, and good after -sales service.
3. Check the appearance
① The paint of the shell should be bright and uniform. There must be no peeling or falling, and the feel is smooth and flat.
② The surface of the casting should be flat. There is no crack or sand eye that can be seen by the naked eye. The appearance of the plate gold should be smooth. The surface of the plating part should be bright without rust.
③ The surface of the tire should be smooth, the pattern is regular, without bubbles and cracks.
4. Check the safety protection device, whether the safety warning signs are complete
① Check the starting shaft head of the engine.In order to prevent people dangerous when the engine is approaching during the operation of the engine.
② The belt and belt must have a protective cover.In order to prevent people dangerous when the engine is approaching during the operation of the engine.
③ There should be a protective cover on the exhaust pipe.In order to prevent burns during the fucking author accidentally contacting.
④ The ladder and pedal on the car should have non -slip mesh patterns and raised edges or gears.In order to prevent the driver from slipping under the car, causing injuries and injuries.
⑤ The axis of the power output shaft must have a cover.In order to prevent people dangerous when the engine is approaching during the operation of the engine.
⑥ In the operating device that is not obvious in the manipulation direction, there should be a symbol that indicates the direction.To prevent errors.
5. Check the manipulation agency
① The throttle and the tie rod are reliable, and the trial step has no card.
② Push the main and auxiliary transmission of the main and sub -transmission bars according to the operating regulations to confirm its reliability.
③ When the steering wheel does not move the front wheel, its free rotation angle should not be too large, less than 30 degrees.
6. Test the car
① Check the height of engine oil, add diesel and cooling water.
② When the environmental temperature is above 5 ° C, it will be launched three times in a row, and there should be two times in 30 seconds.
③ Running for 10 minutes under medium throttle, the sound of smoking and engine should be observed continuously.
④ After 10 minutes, reduce the throttle as much as possible, run at low speed (idle), and the sound of the engine should be stable.
⑤ Gradually increase the accelerator, and the sound of the engine should be stable. When the throttle is maximized, the exhaust pipe does not rush to smoke.
7, parking for leakage and oil leakage inspection
Observe the binding surface of each rotation part, there should be no leakage and flow marks.The combination of the hand and static should be wet.
What are the precautions for buying agricultural tractors?
1. Check and check random attachment, documents and documents
Product qualification certificates, agricultural machinery promotion licenses, "three packages" vouchers (service cards), instructions and maintenance manuals and attachments.
2. Come on invoice
After purchasing the goods, they actively ask the seller to ask the fiscal tax department to formally printed invoices.
