When a tractor is working in the field, it often encounters ditching, climbing fields, muddy mud, and trapping, flying, and overturning. In order to ensure the safety of field operations, drivers should be able to correctly handle the handling of these common problems.
Over the ditch. Generally, deep and wide trenches are filled first or paved with a springboard before passing; shallow and narrow ditches can be driven through a low-speed gear, ie, the tractor body and the ditch become a certain angle, so that the tractor's left and right front wheels and the left and right rear wheels are In order to reduce the impact of locomotive vibration, if it must be driven straight through the topography, first let the front wheel slowly ditch, and then add the fuel to make the front wheel ditch and then let the rear wheel slowly ditch, and finally increase the throttle Let the rear wheel ditch, if the tractor traction farm tools, should first adjust the farm tool to the highest transport position; when hanging farm tools, should adjust the limit chain, to prevent swinging farm tools, and depress the cylinder positioning valve, so as not to produce high-pressure shock within the tubing Burst; when the rear wheel is ditched, the clutch pedal must not be lifted to prevent the tractor from tilting. When the tractor is passing the ditch, a springboard is used to pave or fill the ditch; the engine can also be turned off and cranked through.
Climb the fields. The generally lower ridges can drive straight or sloping through. The methods used are similar to those in ditches. If the ridges are tall and steep, or if the tractor moves from lower terraces to higher terraces, the ridges should be filled with rakes. Stones, etc., or guided by a springboard, slowly pass through the low gear to avoid tilting or vertical overturning of the tractor. When Shimoda, or when shifting from a higher field to a lower field, should also be guided on an underlay mat or shop floorboard to suspend agricultural implements, the application should be applied at a low speed.
The more muddy. When the tractor is working in a soft and moist field, if there is accumulated water in the field, it is necessary to go around first, first plough the part without water, and try to reduce the ploughing and cultivation depth of the implement and reduce the traction so as to avoid slipping into the car. When muddy roads are used, they should stabilize their direction, choose dry roads and existing roads as far as possible, reduce the speed, use as little braking as possible, and avoid the use of emergency brakes to prevent the vehicle from sliding sideways; The water is deeper and should be filled before passing.
Trapped cars. When the tractor's driving wheel slips into a car, it should immediately stop, raise the farm tool, and not blindly refuel the front gate and retreat, otherwise it will sink deeper and deeper, then use wood, stone, firewood and other mats under the rear wheel, Drive out in low gear; if the drive wheel of the tractor is slipping, it can also be driven out with the differential lock. Note that you must not stop your car while driving out of the stumbling block, because the chiller requires a large amount of traction at the start and the tractor will start to retract after it restarts. When a tractor is stuck in a tractor, it can be hung low, and the decompression cranks the crankshaft so that the tractor can be driven out of the trap. If the non-slip iron wheel of the tractor is caught in the mud of the field, the long bamboo bar can be used to cross the non-slip wheel spokes, crank the crankshaft, and use the bamboo bar. The supporting role allows the drive wheel (skid wheel) to exit the mud pit.
Speed. When the tractor suddenly jumps in a field operation, it should immediately close the throttle and increase the load on the tractor (if the brake is not lifted or the depth of the implement is increased), the tractor will be turned off. Don't take off the parking, otherwise the engine load will reduce the speed will increase sharply. If the tractor is in the middle of a stop, you should immediately close the engine throttle, loosen the high pressure tubing nut, or block the filter inlet with a towel or rag. Mouth, or pull the decompression handle to turn off the engine. After the flame is turned off, the cause of the malfunction should be carefully searched and eliminated.
Overturned. Because of the poor stability of tractors, the unevenness of field roads and the tilt of cultivated land, tractors (especially walking tractors) are prone to rollover accidents. After the tractor is overturned, the engine should be turned off immediately, the tractor should be upright as soon as possible, and the vehicle should be fully inspected. Check if there is muddy water in the fuel tank, crankcase, cylinder and gearbox, whether the body, cylinder head, cylinder liner, and traction frame are cracked, and whether the crankshaft, camshaft, connecting rod, valve rod, etc. are bent or deformed. If the items are loose, etc., restart without any problems. In order to prevent the occurrence of rollover accidents, in addition to the operation essentials of the above-mentioned ditches and climbing fields, the following points should also be noted: (1) Steering handles must not be squeezed when the tractor is started; (2) Under the tractor In the case of steep slopes, the steering operation is opposite to that of the flat steering operation; (3) Emergency braking is not allowed when passing through muddy roads; (4) High-speed sharp turning is not allowed when the unit is turned around in the field; (5) The driving speed should not be excessive when the tractor crosses the slope; 6) The tractor shall use the reverse gear when suspending the agricultural implement on the steep slope; (7) Before the tractor works in the field, it shall first check whether there are hidden traps in the field; (8) The tractor shall not be too close to the shoulder when driving on the field tractor road.
