The use of high horsepower wheel tractor maintenance and selection of common sense

First, the use of tractor attention:

1. New or overhauled tractors must be worn out before they can be used normally. Reduce the life of the tractor.

2, tractor components should be strictly in accordance with the manufacturer recommended oil, solution use.

3. Do not increase the engine speed only by controlling the throttle.

4. Always check bolts, nuts, and other loose parts at each connection.

5, the maintenance of the electrical system must first remove the battery ground wire to avoid the electrical parts burned.

6. Before inspection, adjustment and maintenance of tractors and agricultural implements, they must stop and turn off the engine, put the gear lever and power output lever in the neutral position to lock the parking brake, so that all moving parts are stationary.

7. When towing a trailer, it must use a towing hook and cannot use a three-point suspension.

8. When the tractor is driving with a farm implement, the position control handle should be placed in an ascending position and the agricultural implement suddenly drops to cause an accident. And to lock the farm tool to prevent the lifter handle from being touched. 9. The adjustment and installation of the tire must be performed by experienced personnel using special tools to avoid serious accidents caused by improper installation of the tire. 10. When the engine is in working condition, do not twist the water tank cap. Do not unscrew the tank cap until the engine has stopped and cooled.

Second, tractor operation knowledge

1. Do not start to lift the clutch. Slowly release the clutch pedal while properly increasing the throttle. Otherwise it will cause the impact of the clutch assembly and transmission parts, and even damage.

2. The secondary clutch cannot be pulled up (separated) for a long time, otherwise it will cause early clutch damage. Should pay attention.

3, the tractor is strictly prohibited to hang up the neutral or step down the clutch pedal sliding downhill.

4, the steering of the tractor

When the tractor is turning to reduce the throttle or shift to the low gear, a sharp turn must not be made using a single-sided action.

5. The shifting of the tractor and the selection of the working speed will cause the steering wheel to steer the steering wheel when the clutch assembly speed is reduced. High speed tractor

Choosing the correct working speed of the tractor will not only achieve the best productivity and economy, but also extend the life of the tractor. When the tractor is working, it should not be overloaded frequently and the engine must have a certain power reserve. The speed of tractor field work should be chosen so that the engine is working under about 80% load.

6, the use of tractor differential lock

Differential locks generally remain disengaged while the tractor is working. When the rear wheel of the tractor slips badly. (or when in a pit), the differential lock control pedal should be stepped on and held in this position to allow the differential lock to engage and drive the tractor out of the slip zone. 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.

7, the brake of the tractor

Under normal circumstances, you should first reduce the engine throttle, then depress the main clutch pedal, and then gradually depress the driving brake operating pedal, so that the tractor stopped. In case of emergency braking, the main clutch pedal and the service brake operating pedal should be depressed at the same time. During driving, the driver is not allowed to place his or her foot on the brake or clutch pedal. Special reminder: When the tractor is driving on the road, the left and right brake pedals must be interlocked. When the tractor is parked on the slope, it is necessary to hang up the gear before releasing the brake pedal after the engine is turned off, hang the forward gear when going uphill, and hang up the gear when going downhill.

8, front-wheel drive operation

When the tractor is working in heavy field in the field or working on moist and soft soil, the front drive axle is normally engaged. When the tractor is used for general transportation on hard roads, the front drive axle is not allowed to be engaged, otherwise it will cause the early front wheels to work. Wear.

9, hydraulic output valve and its operation to achieve four-wheel drive operations.

The tractor is equipped with a single-acting or double-acting hydraulic output valve, and the hydraulic output valve operating handle is operated to control the single-acting or double-acting cylinder on the implement. The hydraulic output valve of the pulling machine is adjusted to have a double action before leaving the factory. If a single-acting agricultural implement is required, the user can adjust it to a single-acting hydraulic output.

10. Tractor oil requirements:

1) Select different grades of diesel according to different environments and seasons. It is strictly forbidden to mix different grades of diesel fuel 1

2) The fuel oil and transmission hydraulic oil added to the fuel tank must be filtered or precipitated for at least 48 hours before they can be used.

3) Do not fuel the fuel tank 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.

Third, the maintenance of the tractor:

Before use, the tractor must be worn out before use, otherwise it will shorten the life of the tractor. During the use of the tractor, due to a variety of adverse factors, the ability of parts and components will gradually reduce or disappear, and fuel, lubricant, coolant and other substances will be gradually consumed, and the technical status of the whole machine will deteriorate. Therefore, the tractor must be timely cleaned, fastened, adjusted, replaced, added, etc. to maintain the tractor's normal working condition.

After the break-in is completed, the tractor must immediately perform a full technical maintenance. The technical maintenance content is as follows:

(1) After the engine is shut down, the engine oil in the oil sump and the steering oil tank will be released and the filters in the oil pan, oil filter, diesel filter, oil filter, air filter and steering oil tank will be cleaned. Net, after replacing the diesel filter element and oil filter, inject new lubricant. While hot, the lubricating oil from the drive train, hoist, and front drive axle is released. At the same time, the suction filter of the hoist is removed for cleaning. After reinstalling, the new drive hydraulic oil N100D is added to the drive train as required.

(2) Release cooling water and add new coolant. (If the winter temperature is lower than 0°C, the cooling system of the tractor's engine should be filled with antifreeze. If the tractor is not filled with antifreeze, the water should be drained when it is stopped to prevent the water from freezing and cracking the body.) 3) Check the free travel of clutches and brakes and adjust if necessary. 4) Check tighten all external bolts, nuts and screws. 5) Add grease to each part of the tractor that needs to be greased according to the service instructions.

(6) Check the front and rear tire pressures. Insufficient air is inflated according to the specified value.

(7) Check the tractor for leaks, oil leakage, water leakage, etc.

(8) Carry out maintenance on the diesel engine according to the instruction manual. Fourth, how to choose high-power (horsepower) wheel tractor farm machinery: should be ruled out.

The matching of agricultural implements and tractors should be reasonable. When the efficiency of tractors is greater than that of agricultural implements, the economy of operations is poor and the implements are easily damaged. When the effectiveness of agricultural implements is greater than that of tractors, the power of tractors is poor, and the efficiency of agricultural implements is low, and even operation is impossible. Therefore, when matching agricultural implements, the supporting power on the agricultural implement instruction manual should be consistent with the power of the supporting tractor. The speed of the agricultural implement must be consistent with the tractor's power output rotation speed. Before the agricultural implements are connected with the tractor suspension mechanism, the necessary adjustments shall be made according to the “Agricultural Tool Instructions for Use”.

note:

1. When the tractor's power output shaft is working with tools, the tractor can't turn sharply to prevent damage to the universal joint.

2. Before adjusting the agricultural implements, the PTO clutch must be disengaged first, and the control handle should be returned to neutral and the engine should be off.

3. Before using the power output shaft to drive the agricultural implements, it is necessary to check the rationality of the matching between the tractor and the driven implements. In general tillage, the angle between the power output shaft and the universal joint transmission shaft should be no more than 10 degrees, and after the ground turning to enhance the implement, the power The angle between the output shaft and the input tool of the agricultural implement and the drive shaft shall not be greater than 30 degrees. At this time, the height of the rotary cultivator knife from the ground shall not be less than 250mm. At the same time, it should also check whether the safety clutch on the universal drive shaft of the farm implement is valid or not. The safety clutch should slip in the event of an overload.
