The correct purchase and use of tractors can ensure the economic benefits of farmers' friends, ensure the safety of operations, and obtain timely "three guarantees" maintenance services. During the purchase process, pay attention to the following points:
First, look at the manufacturers. In general, manufacturers that have more local tractors and better reputation are selected. Such a manufacturer has already established a thoughtful after-sales service system in the local area, and farmers' friends can use it with confidence. They do not need to timely supply of spare parts or worry about the “Three Guarantees†maintenance personnel not getting in place.
Second, look at the appearance. The working conditions of the tractor are rather harsh and the appearance must be heavy, strong and durable. Therefore, when purchasing tractors, the first thing to do is to check the appearance quality. The whole machine should be free of distortion. There should be no lack of paint and scratches on the sheet metal, and the surface should be smooth and smooth. The paint should be bright and uniform. There should be no leakage, peeling, and shedding. And rust; external parts intact, the smooth surface of the castings, no cracks, welds welded parts to be smooth, solid; for some important parts, to check whether the bolts are complete and reliable, can not have leakage oil phenomenon. The surface of the tire should be smooth, the pattern should be neat, without cracks, and it should have its own elasticity. Belt-driven tractors should check the quality of the V-belt. Generally, the good quality feel is relatively soft, elastic, and uniform in size, without uneven thickness. The safety protection devices, warning signs and lights shall be complete and effective. Each operating part shall have obvious signs and symbols. Each dangerous part shall be equipped with a protective cover.
Third, we must consider the performance and price ratio. When buying a tractor, you can't just consider the price factor. The map is cheap. Some of the cheaper products are actually traded at the expense of the product's performance or quality. When the purchase price is too low, they have to pay a higher price in the future. For example, some farmers’ friends are cheap and buy tractors with the same power as the other chassis, which are nearly 100 kilograms less than the other. As a result, when workers lose their jobs, they lose out. Therefore, when purchasing, be sure to compare with each other to see the overall benefits.
Fourth, to check the operating agency. The operating mechanism should be effective and reliable, flexible and comfortable to operate and free from jams. First of all, to check the clutch, it should be completely separated, combined with smooth, effective in place, safe and reliable, there should be no slip phenomenon. Secondly, check the shift lever. When shifting the gear, there should be a clear feel. There should be no jamming, difficulty in hanging the gear, or the phenomenon of not hanging on the gear. In the stop state, the main gear lever can only be put on a gear from the neutral position. When walking, you can't automatically get out of gear or make a mess. Steering and braking operations must be flexible and reliable.
Fifth, to start the operation check. Start the engine for operation check. Before starting the engine, check the oil level of engine oil, gear oil, and whether there is fuel and cooling water. After everything is normal, you can start and check if the engine start is difficult. After the engine runs smoothly, observe the color of the smoke emitted by the exhaust pipe. The smoke emitted by a diesel engine during normal operation is colorless or light grey. During the operation, it is necessary to observe whether there are abnormal noises in each running component. After about ten minutes of running, there should be no oil leakage, water leakage or air leakage, and there should be no odor.
Six, to check the random items. After selecting the tractor, check the technical documents, random tools, accessories, and spare parts against the packing list and verify that the certificate and the machine number are the same. Also ask the sales unit for a formal sales invoice. This is not only the proof of the user's purchase payment, but also the user's "three guarantees" certificate. It is a necessary procedure for the user to apply for a license and other formalities in the future. Also remember: Do not forget to check and fill out the three-pack service card. The State has expressly stipulated the “Three Guarantees†maintenance for tractors and their supporting farm implements. This is the basis for claiming warranty and claims from production companies when quality problems occur in the products purchased by users. When buying tractors, you should look more and ask more and learn more about the relevant knowledge and working principles of agricultural tractors. If necessary, you can consult the local agricultural machinery management department and the quality and technical supervision department. Only in this way can you purchase the tractors that are satisfactory.
In the process of use, we must also pay attention to the correct method of use, otherwise it will shorten the life of the tractor, and even cause safety accidents.
First, pay attention to the use of new cars. New or overhauled tractors must be worn out before they can be used normally, and bolts, nuts, and other loose parts must be inspected frequently at each joint.
Second, start slowly. When starting, slowly release the clutch pedal and increase the throttle accordingly. Otherwise, it will cause impact on the clutch assembly and transmission parts, and it is forbidden to engage neutral or step down the clutch pedal to slide downhill.
Third, we must turn right. When the tractor is turning, it should reduce the throttle or shift to the low gear position. When the tractor speed decreases, the steering wheel or steering handlebar can be used to steer.
Fourth, we must use differential locks in due course. Differential locks generally remain disengaged while the tractor is working. When the unilateral slip of the rear wheel of the tractor is serious (or when it is in a pit), the differential lock control pedal should be stepped on and kept in this position to combine the differential lock and drive the tractor out of the slippery area. When the differential lock is engaged, the tractor cannot turn and it will cause abnormal wear of the tire, damage to the central drive, and even rollover.
Fifth, to effectively brake. Under normal circumstances, you should first reduce the engine throttle, and then depress the clutch pedal, so that the tractor stopped. During driving, the driver is not allowed to place his or her foot on the brake or clutch pedal. When the tractor is parked on the slope, wait for the engine to turn off and then hang up the gear before releasing the brake pedal and hang the forward gear when going uphill and hang the reverse gear when going downhill.
Six, to use oil properly. All parts of the tractor should be used strictly according to the manufacturer's recommended oils and solutions. Different grades of diesel are selected according to different environments and seasons. It is forbidden to mix different grades of diesel fuel. The fuel tank must not be refueled while the engine is running. If the tractor is working in hot or sunshine, the tank cannot be filled with oil. Otherwise, the fuel will overflow due to swelling, and if it spills, wipe it dry immediately.
