Tractor commodity knowledge and purchase considerations

First, commodity knowledge Agricultural tractors have three types of walking tractors, wheeled tractors and crawler tractors; press power can be divided into large, medium and small tractors. Among them, the walking tractor is a small tractor with a power below 11 kW (15 hp). It is mainly suitable for farmland operations and short-distance transportation operations in small fields, and is commonly used in rural areas in the south. Wheeled tractors are divided into two types: belt drive and power output shaft drive. The belt drive is generally a small four-wheel tractor with a power of 8.8kW to 14.7kW (12 horsepower to 20 horsepower); the power output shaft is driven by a large one. Medium-sized tractors, with a power of 14.7 kW (20 hp) or more, are becoming more and more powerful as their production needs; wheeled tractors are mainly used for farmland operations or transportation operations in rural areas in northern China, and large-scale wheeled tractors are suitable The use of large areas of farmland production can greatly increase production efficiency. Since tracked tractors can be equipped with bulldozers, they are generally used in farmland infrastructure construction and water conservancy projects. Its power uses diesel engines. Second, the choice and identification The following mainly describes how to choose and identify the most used small tractor farmers. 1, the form of the choice of the overall belt drive is usually called a small tractor small four-wheel tractor, in recent years, the market has a small four-wheel tractor 11.0kW (15 hp) and 13.2kW (18 hp) two. The 14.7kW (20 hp) and 8.8 kW (12 hp) small four-wheel tractors are less on the market. There are two types of diesel engines installed on small four-wheel tractors. One is an evaporative water-cooled diesel engine, and the other is a circulating water-cooled diesel engine. Because these two types of diesel engines have different structures and parts cannot be interchanged, you should select the type of diesel engine that is commonly used in your area when you purchase a tractor. This is very important for future repairs and maintenance. 2. Choose brand-name products Because the brand-name products are recognized by the public in long-term use, or approved by authoritative departments (such as the agricultural machinery promotion license product of the Ministry of Agriculture), its product quality is reliable, performance is advanced, product coverage is large, and after-sales service it is good. 3, check the appearance of a shell paint should be bright, to be uniform, there can not be peeling, shedding phenomenon exists, feel smooth and smooth. 2 The surface of the casting should be smooth, there should be no cracks and trachoma that can be seen by the naked eye, the appearance of the sheet metal part should be smooth, and the surface of the electroplated part should be bright and free of rust. 3 The surface of the tire should be smooth, regular pattern, no bubbling, cracks. 4, check the safety protection device, safety warning signs are complete 1 check the starting shaft of the engine, the end of the shaft can not highlight the plane of the engine body. In case the person is close to the engine during operation, danger may occur. 2 Pulleys and belts must have protective covers. In case the person is close to the engine during operation, danger may occur. 3 The exhaust pipe should have a protective cover. In case of accidental contact with the operator, it will burn. 4 Steps and pedals on the car should have non-slip textures and raised edges or ribs. In order to prevent the driver from getting on and off when the car slips, causing a fall injury. 5 PTO shaft head must have a shroud. In case the person is close to the engine during operation, danger may occur. 6 In the operating device where the direction of operation is not obvious, there shall be a sign indicating the direction. To prevent misuse. 5, check the operating mechanism 1 throttle and tie rod connection is reliable, try step on no touch. 2 Push and pull the main and auxiliary shift levers (shift levers) according to the operating rules to confirm their reliability. 3 When the steering wheel is not moving at the front wheel, the free rotation angle should not be too large, and should be less than 30 degrees. 6. Test Run 1 Check engine oil level, add diesel and cooling water. 2 When the ambient temperature is higher than 5°C, it shall be started three times in a row. Two of them shall start smoothly within 30 seconds. 3 Operate for 10 minutes under moderate throttle. Observe that the smoke and engine sound should be continuous and steady. 4 After 10 minutes, reduce the throttle as much as possible, operate at low speed (idle speed), and the sound of the engine should be steady. 5 Gradually increase the throttle, the sound of the engine should also be smooth, and the exhaust pipe should not emit black smoke when the throttle is at its maximum. 7. Stop for leaks, leaks, and inspections. Observe that the joint surface of each rotating part should be free of drips and flow marks. Hand and static joint surface should be no moist. 8, check, check the random attachment, certificate and document product certification, agricultural machinery promotion license, "Three Guarantees" certificate (service card), instruction manuals and maintenance manuals and accessories. 9, after the purchase of goods, take the initiative to ask the seller for invoices formally printed by the financial and taxation departments.
