Problems to Be Paid Attention to in the Use of Small Four-wheel Tractors

1. Less equipped transmission belt The small four-wheel tractor is equipped with three triangular drive belts, and some of the operators can only use one or two and top three. When the tractor is working, the load increases, which causes the drive belt to slip seriously. Not only the transmission efficiency is reduced, but also the output power is decreased, and the belt is heated and delaminated, deformed and worn faster. Therefore, the drive belt should not be rooted.
2. The long-term non-cleaning cooling system keeps the tractor's water tank open upwards. When it is used and parked, it will fall into the dust, sometimes it will be filled with dirty hard water, and the impurities in the water will precipitate. As time goes by, the dust and impurities will build up more and more, and it will form scales to clog the water channel. Affects the engine's heat dissipation, causes the locomotive's temperature to rise, the engine oil thins, and the lubricating performance deteriorates, which accelerates the wear of various moving parts, and also causes the parts to expand, affecting their technical performance, reducing the power, and causing burning of tiles when serious. Axis and viscous cylinder accidents.
3. Freely modify some drivers to modify parts at will, destroying the original car's mechanical properties. For example, in order to increase the driving speed, some drivers increase the diameter of the active pulley, which will cause the following hazards:
1 After the pulley is enlarged, the transmission ratio is changed, and the clutch speed is increased. During the operation, when the engine speed changes, the impact load increases, and the torsional vibration increases, which shortens the service life of the clutch components.
2 The contact area between the belt and the wheel increases, easily causing the belt to break and accelerate the belt damage.
3 As the driving speed increases, the traction force is reduced, and dangers are easily caused during transportation and climbing. At the same time, the load of the locomotive increases, the temperature increases, the lubricating oil becomes thin, and the oil film is difficult to form, accelerating the wear of the crank connecting rod mechanism and various moving parts of the engine.
4 The maneuverability and stability of the tractor are damaged, and it is easy to cause early wear of parts of the braking system due to the failure of braking.
4. Some drivers who are heavily overloaded are randomly overloaded during transport operations. This overloads the locomotive for a long time. The hazards are:
1 After the locomotive is overloaded, parts of the engine, transmission system and the running part are subjected to increased force, the locomotive temperature increases, the lubricating oil becomes thinner, and the lubricating performance is reduced.
2 When an emergency situation is encountered, parking cannot be achieved within an effective distance, so that the braking distance can be lengthened, which can easily cause accidents.
3 The fuel consumption increases, the exhaust pipe emits black smoke, and the combustion chamber is prone to carbon deposition, which accelerates the wear of pistons and cylinders.
5. Traction starting some tractor tractors start, due to the viscosity of the gearbox and the oil sump inside the oil, the locomotive's movement resistance also increases, when the clutch is fast, the transmission gear is affected by the impact of the load, Frequent use of this method will cause the gear to break due to fatigue, and it is strictly forbidden to use this method to start the locomotive in cold weather.
