Main gear shift lever A Sub gear shift lever B


Figure 2-1 Gear shift of tractor

Tread the main clutch pedal; operate the sub gear shift lever B to make it pushed leftwards from the neutral position; and then pushed forwards to get the Medium stage M; if it is pushed backwards, then Reverse stage R will be gotten. If it is pushed rightwards from the neutral position and then pushed forwards, then Low stage L will be gotten; if it is pushed backwards, then high stage H will be gotten

Tread the main clutch pedal; make the main gear shift lever A moved leftwards from the neutral position; and then pushed backwards to get stage 2; and stage 1 will be gotten if it is pushed forwards. If it is moved rightwards from the neutral position and then pushed backwards, stage 4 will be gotten; and stage 3 will be gotten if it is pushed forwards.

The optimal production efficiency and economical efficiency can be obtained if the proper driving speed of tractor is selected, and the service life of the tractor can be prolonged. The tractor shall not often work under overload condition, and the engine shall have certain power reserve. As to selection of driving speed when working in the field, the diesel engine shall work under about

80% load. When the tractor works under light load and the driving speed is not high, High 1 stage small throttle work can be selected to save fuel.

The basic gear stage for field work: Low stage 4, medium stage 1, 2 and 3 for plough; low stage 1, 2 and 3 for rotary tillage. Low stage 4, medium stage 2 and low stage 3 for harrowing.

When the diesel engine is deep-voiced and has speed drop and black smoke during operation, it shall be changed over to low stage 1 and small throttle, so as to prevent tractor overload. When the load is light and the working speed shall not be too high, high stage 1 and small throttle can be selected, so as to save fuel.


1. When engine running, before gear shift, the main clutch pedal shall be treaded to floor, and the gear shift shall be performed after several seconds, so as to prevent poor engagement of sliding sleeve of gear box (which will lead to “collision of teeth”);

2. The tractor only can be at back gear stage when it is still;

3. Do not make the hands placed on the gear shift lever when the tractor is driving, or the hand pressure will be transmitted to the gear shift fork in the gear box, which will lead to premature wear of the shift fork.

2.7 Operation of Differential Lock

During the operation or working process of tractor, if the tractor can not move forward due to sticking or the unilateral driving wheel is slipping, the differential lock can be connected according to the following steps to rigidly connect the left driving wheel and the right driving wheel so as to drive the tractor out of the slipping section at the same speed.

-17-

2.8 Using of Front Drive Axle

This series of four-wheel drive tractor works in farm fields under heavy load or works on humid and soft soil; if only driven by the rear wheel, the traction property of the tractor may present insufficiently; at this time, hanging the front drive axle can increase the traction force of the tractor and reduce the slipping rate, thereby improving the working adaptability of the tractor. In order to be convenient for connecting and separating the front drive axle, the following operation procedures shall be followed:

2.8.1 Hanging of the Front Drive Axle

Step on the main clutch pedal, hang the position of the gear-box well, and then loose the clutch pedal slowly, wait for the slighting moving of the tractor and timely pull the front drive axle operation handle upward, so as to change two-wheel drive to four-wheel drive.

2.8.2 Disconnection of the Front Drive Axle

When it is necessary to disconnect the front drive axle, step on the main clutch pedal and push the front axle operation handle downward, so as to separate the front drive axle


1. When the tractor is conveying on a hard roadway for ordinary transportation, it is forbidden to connect the front drive axle, otherwise it will cause early stage abrasion of the front wheel and increase oil consumption. Only when the roadway is slipping and the back wheel can easily slip after climbing large slope during raining or snowing day, the front drive axle be connected. After the tractor drives out of the difficult section, the front drive axle shall be separated.

2. When the tractor is conveying, the front tyre wears faster and the tyre treads at the left and right side of the tyre wear unevenly; the left tyre and right tyre can be exchanged for use according to the condition.

-18-


2.9 Braking of the Tractor

Generally, firstly decrease the throttle, step on the clutch pedal, and then gradually step on the brake pedal according to the condition to steadily pause the tractor.

For emergency stop, you shall simultaneously step on the clutch and the brake pedal and cannot solely step on the brake pedal, so as to prevent rapid abrasion of the brake friction plate or causing engine stop.

When a trailer is added for braking, you shall adjust the length of the brake valve hang rod to firstly brake the trailer and then brake the main engine.

When the tractor is running on road, you shall lock the left brake pedal and the right brake pedal together by the chain board.

Warning

:

1. Before departure of each time, you shall uniformly check the oil level of the brake oil tank as well as whether there is oil leakage generated at the brake piping or not; if the oil level of the oil tank is too low or there is oil leakage generated at the brake piping, you shall timely find out the reason, repair it, otherwise major incident like brake failure will be raised.

2. When the tractor is running on road, you must interlock the left brake pedal and the right brake pedal together, so as to prevent off tracking and even overturning of the tractor when braking.

2.10 Stopping of Tractor Stop and Flameout of Engine

Flameout of the tractor and stopping of the tractor shall follow the following procedures:

 Decrease the throttle, and reduce the running speed of the tractor.

 Step on the clutch pedal, then step on the brake pedal and place the gear shift lever at the position of neutral gear after the tractor stops

 Loosen the clutch and brake pedal, and then decrease the throttle to lead the engine run under idle speed.

 Pull the flameout pull rod back, the oil pump stops supplying oil and the engine shuts down immediately, and then push it to the position of oil supply

 Turn the power switch to the off position, and shut down all the power sources.

-19-


Notices:

1. After stopping and before flameout of the engine, the driver is forbidden to leave the tractor, so as to prevent the tractor from starting suddenly, which will cause accidental risk.

2. If the tractor must stop at a slope land, you shall engage the gear (engage the forward gear at upslope position, and engage the backward gear at downslope position), and must use parking brake and plug the back wheels by triangle brake shoes, so as to prevent the tractor from suddenly starting and out of control automatically, which will cause accidental risk.


1.When the temperature is lower than zero DEG in winter, turn on the drain valve of the water tank and the drain switch of the engine of the tractor, which does not use antifreeze when the engine is running under idle speed, to discharge cooling water out, and then shut down the engine, so as to prevent freezing of the cooling water which will crack the engine body through frosting;

2. After discharging water in winter, in order to prevent residual water in the outlet pipe of the water tank from cracking the water pipe through frosting, suggest the user to turn on the water discharge switch of the engine after the engine stops, position the flameout handle at the position of flameout and drag the engine to run 2 to 3 times for 15 second with a interval of 2 to 3 minutes, so as to prevent discharging all of the water in the water pipe.

Picture 2-2 Adjusting of front wheel toe-in

2.12Using, Dismounting and Mounting of Type

2.12.1 Using of Tyre

Tyre is the main wearing part of the tractor; and attention must be paid to the using and maintenance of the tyre, so as to possibly prolong the service life.

All the tyres have regulated load values; overburden will deform the tyre excessively, bend the tyre side excessively and crack the tyre easily; moreover, glue will be easily separated from the tyre body fabric and the buffer layer; the fabric layer is loosen until the tyre is broken, especially when the tractor is running on uneven roadway or is impacted by barrier, the tyre will be broken more easily.

The inflation pressure of the tyre must meet the regulations; both lower pressure and higher pressure will affect the service life of the tyre. Lower pressure will deform the tyre excessively, which will accelerate the wearing of the tread, and even quickly grind the tyre casing and cut off the inflating valve as well as increase the running resistance at the same time. If the pressure of the front tyre is too low, it needs more force to operate; higher inflating pressure will crack the tyre body because of excessive stretching, accelerate the wearing of the tread, and increase machine body vibration. The pressure of the tyre shall be properly lower when the tractor is working in farm field; and the pressure shall be properly higher if the tractor is running for road transportation for a long term. The tyre pressure shall be checked by barometer under normal temperature, so as to prevent inaccurate measurement because of heat emitting of the tyre after working. Improper driving operation will also lead the wear or damage of the tyre at an early period. Crossing barrier, at high speed, sudden brake or quick turn shall be prevented when running. Tyre slippage shall be avoided when the tractor is running on macadam.

Don’t adhere chemical corrosive like oil, acid or alkali on the tyre when using and avoid insolation under burning sun as much as possible, so as to prevent ageing and modification of rubber. Regularly check whether the front wheel orientation and toe-in are right or not, so as to prevent eccentric wear of the tyre. When the wear of the tyre figure is uneven, exchange the left tyre and the right tyre for use.

-21-


Note ： Four wheel tractors’ front and rear wheel inflate pressure should be same, as to avoid wearing heavily.

2.12.2 Dismounting and Mounting of the Tyre

Dismounting of the tyre

Special tools shall be used for dismounting the tyre and it is forbidden to use hard tools (like screwdriver) and sledge hammer to beat the tyre, so as to prevent puncturing the tyre or damaging the tyre edge and rim section.

When dismounting the tyre, you shall discharge the air at first, and press the tyre edge at two sides of the tyre casing into the groove of the rim section; then use a crowbar to pry the tyre edge at one side out of the rim section from the position near the inflating valve; and then use two crowbars alternately pry the whole tyre edge out. After taking the inner tyre out, use the same method to pry out the tyre edge at the other side, and take down the tyre casing.

Mounting of the tyre

When mounting the tyre, firstly check whether the rim section and the tyre are matched or not, and there shall be no burrs and serious deformation at the edge of the rim section; then eliminate rust on the rim section, check whether there is breakage on the tyre or not. After wiping up each spare part, coat a thin layer of talcum powder between the inner tyre and the tyre casing during mounting. Lay the rim section flat, mount the tyre casing and step by foot or pry it into the rim section by crowbar.

Put the inner tyre in (slightly underlay the tyre casing) and use galvanized wire to fix the inflating valve in the inflating valve hole of the rim section to prevent slipping. Use a crowbar to pry one side of the tyre casing into the rim section (it will spend most force at the last section and use a hand hammer to slightly knock the crowbar). Finally, check whether the position of the inflating valve is inclined or not and whether the rim edge and the rim section are closely fitted or not. When inflating, recheck whether the inner tyre is broken or not by prying, inflate and at the same time knock the tyre casing by the hand hammer, after inflating to the regulated pressure, then discharge half of the air, so as to make the inner tyre expand normally and eliminate cockle phenomenon.

When mounting the tyre onto the tractor, you shall also pay attention to the direction of the tyre figure; otherwise, the adhering property and abrasion performance will be influenced, and mud will be deposited.

Warning

: it is forbidden to dismount the connecting bolts of the tyre, the drive hub and the hub; otherwise they will fly out and hurt people.

2.13 Using of Balance Weight

2.13.1 Rear balance weight


When the tractor is working in farm field, the quantity of the balance weight can be selected according to different working patterns in order to improve the working performance of the tractor.

Each piece of cast iron balance weight weighs 50kg, and at most 3 pieces can be mounted at one side (150kg).

Notice:

Before dismounting the rear wheel which is provided with the rear balance weight from the tractor, you shall firstly dismount the back balance weight from the tyre, so as to prevent the risk of losing balance.

2.13.2 Front balance weight

In order to adjust the relation between the front balance weight and the back balance weight of the tractor, it is necessary to mount the front balance weight block at the front part of the tractor.

For plough work under heavy load or hanging machines like large scale seeding machinery, in order to guarantee the head o f the tractor does not raise and run safely, the front balance weight with sufficient weight must be mounted.

The front ballast weight 130Kg.

At most 10 pieces of cast iron front balance weights can be selected and mounted on the tractor [each piece weighs 40kg].

Notice: The rear parts of tractor match large agricultural machinery, to assure the safety, we must match enough front balance weight, otherwise the tractor will turn over.

The error is 0-0.5mm.

4.5 Attention for the operation of full hydraulic steering system

This series of tractors adopt full hydraulic steering system. Before delivery of tractors, the steering system has been adjusted correctly. Users shall pay attention to the following items in use.

 Examine screw joint frequently, in case of loosening, it must be tightened in time. There must not be oil leakage at joints of full hydraulic steering system while it is working.

 Examine level in the steering tank. If insufficient, it must be added as required.

 In case of binding or heaviness, or hidden danger of cornering in the turning of steering wheel in everyday use, steering wheel cannot be turned suddenly. Instead, the cause must be analyzed. It cannot be used until fault is removed. Otherwise, it will damage steering components. It is forbidden to conduct coasting with engine off, because the steering oil pump loses power and cannot feed oil. Turning steering wheel at this time will lead to failure of turning

 With respect to installation of full hydraulic steering system, the steering gear must be coaxial with steering shaft and have clearance while turning. After installation, the steering wheel shall be checked whether it is flexible.

-57-


 The oil must be clean. Filter core and oil must be checked frequently by dripping a drop of oil on blotter paper; if there a black center on the oil stain, it indicates that oil should be replaced.

 After replacement of engine oil, the gas in oil cylinder shall be exhausted by loosening bolted joint of steering cylinder to oil pump going on low-speed running for air bleeding until there is no bubble in the outflow oil.


1. Pressure relief valve of constant overflow pump will have well-adjusted safety overfall pressure before delivery. Make sure not to detach and adjust it randomly.

2. Constant overflow pump is a precision part. It is not allowed to be detached randomly under normal circumstances. It must be detached at the place of cleaning, and washed by clean gasoline or kerosene.

5. Storage

If the tractor should be disused for a long time after finishing the field work or due to other reasons, it will be necessary to properly seal and store the tractor.

The tractor should be thoroughly cleaned before being sealed and stored. All connectors must be adjusted and fixed, and the technical service should be done in accordance with working hours, so that the tractor will be kept in good state.


Scientific storage and special maintenance and service are very important during disuse. Otherwise, the deterioration speed of tractor’s technical state will be higher than that in working period.

5.1 Reasons for damage of tractor during storage period

 Corrosion: during the storage period, the dust and vapor in the air will easily enter into the machine through gap and orifice, and the parts will be polluted and corroded. Other parts such as piston, valve, bearing and gear, if they are kept in a position for a long time, they will lose the protection from lubricant film that flows and has pressure, thus the erosion, rust, cement blocking or clamping stagnation will occur, and the tractor will be scraped 。

 Aging: The rubber, plastic and other parts will get aging, degenerated, brittle, corroded, and decayed or lose effect.

 Deformation: plastic deformation occurs in transmission belt, tire and other parts after they sustain force for long time.

 Others: electric parts are affected with damp, the storage battery automatically discharges, and etc.

5.2 Sealing and storing the tractor

 Carefully examine the tractor before sealing and storing it, eliminate the existing failure, keep good technical state, and clean up the appearance of tractor.

 The tractor should be stored in dry warehouse or shed with good ventilation. It can not be stored with corrosive goods and liquid. If the tractor is stored outdoor, select the higher and dry platform, and cover the tractor with tarpaulin.

 Support the tractor off ground with dry wood frame, so that the load can be removed from tire. Regularly examine the air pressure in tire.

 Clean the parts dismounted from tractor and the tools, pack them and store them in dry

-59-

Deposit warehouse.

 Exhaust the antifreeze and antirust in radiator, air cylinder and water pump, the engine oil in lubrication system and the engine oil in hydraulic system.

 Remove the storage battery, and coat the terminal post with lubricant. Store the battery in shady room with fine ventilation and at the temperature of more than 10 ℃ .

 Exhaust the oil in engine and add new engine oil. Operate the engine throttle for several minutes, so that the engine oil will accrete to the surface of moving components.

 Add grease in each lubricating point.

 Coat the electric contacts, connectors and the surface of unpainted metal parts with dehydrate Vaseline (which should be heated at 100 ℃ to 200 ℃） .

 Let out diesel in the tank and clean up it.

 Use the protective material to chock the unclosed tube in the engine.

5.3 Service during the period of sealing and storing tractor

 All the abovementioned requirements for sealing and storing tractor should be satisfied.

 It is necessary to examine whether the corrosion, aging, deformation and other abnormal phenomenon occur in the tractor and components. The problems should be removed in time.

 The crankshaft of engine should be swerved for 10 to 15 circles every two months, in order to prevent rust. For the lubricating parts where grease needs to be added, clear away the old grease and replace new grease.

 Start up tractor one every three months, and drive it with low speed for 20 to 30 minutes to examine whether abnormal phenomenon occurs in each part.

 Regularly wipe the dust on the surface of storage battery with dry cloth, and maintain it regularly by following the Use Manual of Storage Battery.


If the tractor is unused for several months or longer, the engine oil should be replaced at least. Clean the element of engine oil filter. Start up tractor one every three months, and drive it with low speed for 20 to 30 minutes to examine whether abnormal phenomenon occurs in each part. Keep the exterior clean and dry.

5.4 Unsealing tractor

 Clear away the grease.

 Open the closed nozzle, and clean the tractor.

 Add coolant, engine oil, diesel, and add lubricant in each lubricating point.
