is available, put out the flames at the source of the flame. If a fire extinguisher is not available, use sand
or other non-flammable substance to fight the fire.
4.
After any safety incident, immediately dial any necessary emergency services (hospital, fire department)
according to the situation and administer first-aid as necessary.
WARNING:
1. Always operate the tractor in a safe and responsible manner to avoid injury and possible death.
2. Pay special attention to any obstacles that may impede progress or cause an accident before
starting the tractor. Also check for obstacles and impediments that may be covered by the tractor,
an implement or a trailer.
3. Never leave the driver’s seat to start and operate the tractor. Prior to the startup, make sure that various
shift levers are in the neutral position, the throttle lever and the front drive control handle are
disengaged, and the lifter operating handle is in neutral to prevent the sudden start up
of accessories.
4. Do not start the engine by bridging-over the starter solenoid. If you do this, the tractor could lose
control and cause a dangerous situation, which could lead to injury or death.
5. Make sure that the pedals are free from obstacles and able to move unhindered to their home
position. Never keep anything on the floor or around the pedals that could hinder pedal travel. An extra
foot blanket or non-standard floor mats should not be used as they can hinder pedal movement and
cause serious injury or damage.
6. Never get on or off the tractor while it is in motion.
7. Never climb under the tractor while the engine is running.
8. Always remove the keys, set all shift levels to neutral and lock the auxiliary brake handle before
exiting the cab to avoid accidental start up and to keep the tractor from moving unattended.
9. Keep your speed under control at all times. Brake prior to turning in order to maintain your load
3
Safety Precautions
and avoid tipping.
10. When crossing or going under a bridge or going through a tunnel, pay full attention to the
load height.
11. Use the lowest gear with the clutch enabled on a down slope. Never put the tractor in neutral and
coast downhill as this can cause instability. Never change gears on a down slope as this can cause
instability and a possible rollover.
12. Avoid sudden turns at high speed or using unilateral braking to turn as this can result in instability.
13. When driving on roads, obey all local traffic indicators and laws.
14. Keep a safe distance between the tractor and any other vehicles that may be on the road.
15. Roadbeds along the ditch line tend to be more fragile. Pay specific attention to the weight of your
vehicle when riding on the road shoulder.
16. Never overload the tractor. Running the tractor over the specified limits can cause damage to the
tractor and can result in injury.
17. When driving at night, make sure that you have proper lighting to avoid any collisions.
18. When working in tall grass or hay, a spark-extinguishing device must be affixed to the exhaust pipe to
avoid accidental fires.
19. Always slow down when working in wet or rainy conditions to avoid slippage and instability.
20. Always operate the tractor at a safe speed.
21. When attaching implements, make sure all 3-Point hitch pins are securely fastened. When disconnecting
implements assure all 3-Point hitch pins are disconnected.
22. When lifting, reduce engine speed to avoid damage to tractor and personal injury.
23. Upon charging the battery, insure proper ventilation.
24. Beware of overhead high voltage transmission lines!
Caution:
1.
Check nuts, bolts, and other loose components regularly and tighten as required. This could prevent
a potentially dangerous situation.
2.
When the tractor runs the power take-off (PTO), make sure that there is a safety shield installed.
4
Safety Precautions
Never approach the PTO shaft when it is running. Never take sudden turns when the PTO shaft is
under load, as this can damage the universal joint or the PTO shaft. When the PTO shaft is not
in use, the PTO lever should be returned to the neutral position.
3.
After parking and before shutting down the tractor, the driver should remove the key from the ignition,
set all gearshift levers to the neutral position, and lock the brake handle. This will prevent the
tractor from accidental startup and unattended movement .
4.
When parking the tractor on an incline, the auxiliary brake should be engaged and the engine shut down.
Put the tractor in gear, apply the auxiliary brake and use the triangle chocks to block the rear wheels.
5.
Tire installation and adjustment should be done by trained personnel only, using special tools.
Faulty tire installation may cause a serious accident or damage.
6.
When cleaning the radiator, shut down the tractor and allow the tank to cool for 30 minutes.
7.
Pay attention to all safety precautions when replacing or installing new parts on your tractor.
IMPORTANT ISSUES:
1. Always operate the tractor according to the specified breaik-in requirements. This will prolong the life
of your tractor.
2. Prior to starting the tractor, the oil system, cooling system and electric circuits must be examined.
After startup, strict attention should be paid to the various instruments.
3. Before activating the power take-off (PTO) shaft, make sure that the equipment is properly inspected.
When using PTO driven implements, the angle between the PTO shaft and the universal joint drive shaft
should be no more than a 15° angle; and the hydraulic operating control should be in neutral. After the
farm tool has been lifted, the included angle between the PTO shaft and the universal joint drive shaft
should be at no more than a 20° angle. Never use the implement without checking for a proper connection
with the PTO. This can cause damage to the implement and severe damage to the tractor clutch and power
train. To increase work efficiency, the power supply should never be shut off during a turn, and the lifting

Safety Precautions
height must be maintained at 200 mm. (7.88 in.) above the ground.
4. Hanging farm implements can shift tractor weight. They should be low to the ground before exiting
the tractor.
5. Antifreeze should always be used in the engine cooling system.
6. The front driving axle of tractor should only be engaged in agricultural instances and when roads
are muddy. Overuse of the front drive axle may result in premature wear of the tires and
transmission problems.
7. Only use parts recommended by the manufacturer to replace worn or broken components.
8. Never rest your foot on the brake or clutch pedal when the tractor is in motion as this can cause premature wear
of the brakes and clutch system.
9. When detaching the tractor from any implements, the upper lever of the suspension unit should be adjusted
to the shortest travel and the limit lever adjusted to prevent the implements from swinging out of control.
The locking nuts on the upper and limit levers must be tightened in order to guarantee travel safety and to
avoid damage to the tractor and the machinery.
1.2 Safety Warning Symbols
Caution:
1.
All safety identifiers should be visible and easy to read. When dirty, wash with soapy water and wipe them with
a soft rag.
2.
When the safety identifiers are lost or damaged, contact the dealer or the manufacturer for replacement stickers.
3.
When replacing parts with attached safety warning symbols, the safety identifiers that correspond to that specific
part need to be updated as well.
4.
To prevent injury, accidents and damage, always comply with safety warning identifiers.

Safety Precautions
Preventing Farm Machine Hazards
The following article describes important general safety precautions for machinery such as the NT-204C/NT-254 tractor.
It is reprinted here with permission from Professor Thomas L. Bean, Safety Leader and Professor, Department of Food,
Agricultural, and Biological Engineering, The Ohio State University Extension, The Ohio State University.
AEX-593-91
Thomas L. Bean
Each year, 2,600 farm residents are killed and 230,000 disabled in farm-related injuries, many due to farm machinery.
Farm machinery uses mechanical power to do work. This creates a number of possible hazards for both operators
and bystanders. Even though manufacturers take many steps to make machinery safe, all hazards cannot be removed.
Some machine parts cannot be completely shielded and still do their job. For instance, a totally enclosed cutting blade
could not cut.
Many machinery-related accidents result from human error. The operator either forgot something, took a shortcut or
a risk, ignored a warning, wasn’t paying close attention, or failed to follow safety rules. In addition, guards removed
for maintenance often aren’t replaced.
There are many different kinds of farm machinery: mowers, tractors, shredders, harvesters, grinders, blowers, augers,
balers, etc. They all have similar characteristics and hazards. You can be cut, crushed, pulled in or struck by an object
thrown by these machines. They have cutting edges, gears, chains, revolving shafts, rotating blades, pinch points and
other hazards. You can also be injured if you fall while working on or near any of these machines.
Accidents with farm machinery are often serious, even fatal. It is important to recognize and be alert for machine
hazards and to take precautions to avoid injury.
Shear and Cutting Points
Shear points (Fig. 1 below) are created when the edges of two objects are moved together closely enough to cut a soft
material, as with a pair of shears or an auger. Cutting points are created when a single object moves forcefully or
rapidly enough to cut, as with a rotary mower blade.
Figure 1
10
Safety Precautions
Both shear and cutting points are created on machinery designed to cut, such as harvesters, and on those that are not
designed to cut, such as augers. They are hazardous because of their cutting force and they often move so rapidly that
they may not be visible, so it is easy to forget they are operating or to underestimate the hazard.
Because some shear and cutting points cannot be guarded, it is important to be aware of their hazard and stay alert
when they are operating. It is also important to warn others and to look out for their safety. This is especially true if
there is a danger of thrown objects while using cutting-type equipment.
Pinch Points
Pinch points are another hazard of farm machinery (Fig. 2 below). Pinch points (which should be more appropriately
named mangled or maimed points) are formed when two rotating objects move together and at least one of them
moves in a circle. For example, the point at which a belt runs into a pulley is a pinch point. Belt drives, chain drives,
and gear drives are other sources of pinch points in power transmission devices. Feed rolls, gathering chains and
similar equipment designed to draw crops into the machine also create pinch points.
Figure 2
Fingers, hands and feet can be caught directly in pinch points, or they may be drawn into the pinch points by the
inertia of the moving part or loose clothing that becomes entangled. Contact may be made by falling or brushing
against unshielded parts. You can become entangled in pinch points if you take chances and reach or work near
rotating parts. Machines move too fast to get out of a pinch point once you become caught.
To avoid injury from pinch points, be aware where pinch points occur and avoid them. Wear clothing that fits well and
is not loose or floppy. Never reach over or work near rotating parts. Turn off machinery to work on it. Always replace
shields removed for maintenance.
Wrap Points
Rotating shafts are the most common source of wrap-point accidents, although any exposed machine part that
rotates can be a wrap point. A cuff, sleeve, pant leg, long hair or just a thread can catch a rotating part and result
in serious injury. Entanglement with a wrap point can pull you into the machine, or clothing may become so tightly
wrapped that you are crushed or suffocated. In other cases, you could be thrown off balance and fall into other
machinery parts.
Even a perfectly round shaft can be hazardous if there is enough pressure to hold clothing against the shaft.
11
Safety Precautions
Hazards increase with shafts that are not round. Clothing is more likely to catch if there is dried mud or manure
on the shaft, or if the shaft is nicked. Ends of shafts that protrude beyond bearings are also dangerous. Universal joints,
keys and fastening devices can also snag clothing.
Check all equipment for potential wrap points and, if possible, shield those that can be shielded. Replace any damaged
manufacturer-installed warning labels and place warnings on equipment parts not previously labeled. In addition,
consider painting them a bright color, perhaps with wide stripes. Be aware of wrap points and be alert to their danger.
Crush Points
Crush points are created when two objects move toward each other or one object moves toward a stationary object.
For example, hitching tractors to implements (Fig. 3 below) creates a potential crush point.
Figure 3
Hitch accidents most commonly occur to fingers placed at the hitching point. Wait until the tractor has stopped before
stepping into the hitching position. If possible, arrange the hitch point so that the tractor can be backed into position
without anyone between. Always know what the other person is doing.
Failure to safely block up equipment can result in a fatal crushing injury. A jack may slip, a hose or overhead support
may break, or the equipment may roll. Take extra precautions when working with machinery that is raised for any
reason. The operator’s head or chest can be crushed between the equipment and a low beam or other part of a
farm building. These accidents usually occur when the machine is being operated in reverse. Tree limbs are also
potential hazards when working with tractors and other machinery.
To prevent being crushed or pinned, recognize and avoid potentially dangerous situations. Block all machinery
securely if you must work under it. If an implement can roll freely, block its wheels so it cannot roll.
Free-Wheeling Parts
Many machine parts continue to spin after the power is shut off, including cutter heads of forage harvesters,
hammer mills of feed grinders, rotary mower blades, fans and flywheels. Never touch these parts until they
have stopped moving. This could take 2 – 2 1/2 minutes.
12
Safety Precautions
Springs
Compressed springs (Fig. 4 below) will expand with great force when released, and springs that are stretched will
contract rapidly when released. Know what direction a spring will move and how it might affect another machine
part when released, and stay out of its path.
Figure 4
Burn Points
Be aware of burn points: mufflers, manifolds and even gear cases under adverse climatic conditions. They may
not be severe enough to seriously maim, but they can startle the operator enough to cause him or her to “jump”
into more deadly danger.
Hydraulic Systems
Hydraulic systems contain fluid under extreme pressure. Before loosening, tightening, removing or otherwise working
with any fittings or parts, relieve this pressure. Jet streams from even pinhole leaks can penetrate flesh. In addition,
the liquid is often hot.
Before attempting any service on hydraulic systems, shut off the engine that powers the hydraulic pump. Lower the
implement to the ground and relieve the pressure. Follow instructions in the operator’s manual because the specific
procedures for servicing the systems are very important to your safety.

2.4 Starting the Engine
IMPORTANT ISSUES:
1.
Before starting the tractor, inspect it for damage or loose parts that could cause an accident.
2.
Check the radiator regularly and make sure that you have a clean water/antifreeze mix to avoid
overheating of the engine.
2.4.1 Engine Starting Preparation
1.
Before starting the engine, check to make sure that there are no
loose parts, that each operating mechanism is functioning normally,
that each hose or tube connection is tight and that there is no oil, fuel,
or water leakage.
2. Check the engine oil pan, transmission, rear axle and the hydraulic
system to make sure that their lube oil levels are sufficient.
Figure 2-25. Hand Throttle Position
The radiator should be full of cooling water and antifreeze and
the fuel tank should have fuel.
3.
Check the transmission shifters and the power takeoff (PTO) shaft control handle. Make sure that the
main shift lever, the high/low gear shift lever, and the front drive axle control handle are set in the
neutral position. The 3-point lift lever should be set in the lowering position.
4.
Place the hand throttle half-open, as shown in Figure 2-25.
21
Operation Instruction
5. For a new tractor, or one that hasn’t been used for a long time, an overhauled should be performed
before starting. Before starting, bleed the air from the fuel line to ensure that diesel engine
starts smoothly. The procedure is as follows: first loosen the bleed screw on the diesel filter and discharge
the air in the hose from the fuel tank to the diesel filter with a hand pump until there are no bubbles in the
discharged fuel. Then tighten this screw and loosen the bleed screw on the fuel pump to discharge the air
until there are no air bubbles in the fuel flowing out of the fuel pump. Then tighten this bleed screw.
IMPORTANT NOTES:
1. Clean debris off the radiator regularly to avoid engine overheating.
2. If the tractor is equipped with a combine, heat buildup during operation will become a problem. To make
sure that the engine performs properly, an auxiliary radiator needs to be installed on the tractor.
2.4.2
Engine Start
WARNING: Before starting the engine, make sure that the main gear shift lever, the high/low
shift lever, the shuttle gear shift lever, and the front drive control lever are in the neutral position, and the
3-point lift control lever is in the lowering position. This will prevent the tractor from accidentally starting and
causing an accident or injury.
IMPORTANT ISSUES:
1. Never turn the key for more than 5 seconds. If the engine does not start within 5 seconds, let the starter rest
for 15 seconds and try again. You can do this three times. If the engine still doesn’t start, you need to
trouble shoot the problem to prevent damage to engine components.
2. Once the engine is started, ease up on the throttle immediately. Check the engine oil pressure at this time
to ensure that the oil level is no lower than 9kPa (1.31 psi). The oil pressure indicator light should turn off
at this time.
3. Do not attempt to run at full-load immediately. It is necessary to run the engine at medium speed to warm
it up. When coolant temperature is above 60°C (140F), you can then increase the speed and operate the
tractor with a full load.
4. The engine rpm and load should be varied between low and high speed, especially for a new engine.
Do not attempt to run the tractor at high speed using the fuel throttle lever or the accelerator foot pedal.
22
Operation Instruction
5. When running the engine, the oil pressure and coolant temperature should be checked regularly. During the
normal operations of the engine, the cooling temperature should be around 85°C (185F) and the engine oil
pressure should be 310 to 345 kPa. (45-50 psi).
Starting the Engine in Ambient Temperatures (above 40F):
When the temperature is above freezing, insert the key and turn it clockwise.
Turn to ignition to the ON position to switch on the tractor electrical system.
Step on the clutch pedal and then turn the key clockwise to ST to start the
engine. After the engine is started, release the key immediately. It will
automatically return to the ON position
NOTE: Amp meter should drop to -30.
Figure 2-26 Ignition Switch
Starting the Engine in Low Temperatures (below 40F ):
When starting the tractor in low temperatures (below 23F), use the engine preheater. Put the fuel throttle lever
in the one-quarter throttle position, turn the key clockwise to H position and leave it on H for 15–20 seconds.
Turn the key to the ST position to engage the starter. Release it immediately after starting and the key will
automatically return to the ON position.
When working in a cold climate, consider having an
engine coolant heater permanently installed in the engine
to make cold weather starting easier.
Plug in the engine heater when the tractor is not in use.
NOTE: Amp meter should drop to -30.
23
Operation Instruction
2.5
Running the Engine
1. After the engine is started, ease up on the throttle immediately to allow the engine run at idle. Check the
engine oil pressure to ensure that the indicator on the oil pressure gauge is in the green zone.
2. After the engine is started, do not run a full-load immediately. The engine should be run at idle to medium
speed to heat the engine. When the coolant temperature rises above 140F, you can then increase to high
speed and operate at full load capacity.
3. The engine rpm and load should be slowly increased or decreased, especially for a recently started engine.
Never use the hand throttle to run at high speed.
4. When the tractor is running the engine oil pressure and coolant temperature should be checked regularly.
During normal operations of the engine, the indicator on the oil pressure gauge and water thermometer
should be in the green zone.
5. When running the engine, the oil pressure and coolant temperature should be checked regularly. During the
normal operations of the engine, the cooling temperature should be around 85°C (185F) and the engine oil
pressure should be 310 to 345kPa. (45-50 psi).
IMPORTANT ISSUES:
In order to avoid damage to the engine, never let the oil pressure fall below 9kPa (1.31psi). If the oil pressure is
dangerously low, shut down the engine and troubleshoot the problem immediately.
2.6 Putting the Tractor in Motion
1. Set the shuttle gear shift to Forward or Reverse.
2. Set the range gear shift into the Low range.
3. With the engine running at low speed, step on the
clutch pedal. Then, put the gear shift level in the
desired speed. To prevent gear tooth breakage in the
transmission or early clutch damage, do not start the
engine in the High gear range.
Figure 2-26 Tractor Start
4. Release the parking brake.
5. Gradually increase the engine speed and slowly release the clutch pedal until the clutch engages, then fully
release the clutch to get the tractor running properly. Gradually accelerate to the required operating speed.
24
Operation Instruction
6. Always step on the clutch when changing gears to prevent damage to the transmission.
7. When driving the tractor on the road, make sure you use the turn signals to signal your direction and the
horn to warn others. Lower your speed before making a turn and make the turn slow and early. If the turn is
extremely sharp, slow your speed and take a wider angle.
8. When turning the tractor on a tight angle or on soft soil, steering becomes more difficult due to front wheel
side slip. To make the turn easier, step on brake pedal on corresponding side while making the turn.
WARNING:
1. When running the tractor at high speed, never use just one-side brake for sharp turns. Use both
brake pedals. If you hear an abnormal noise when steering, stop operation and adjust so that
you do not cause damage to the hydraulic steering system due to an overload.
2. When operating in the field, prior to turning or backing up, the parts and components of a towed
implement need to be lifted clear of the soil to prevent equipment damage or injury.
2.7 Steering the Tractor
When driving the tractor on the road, press the turn signal switch on the control console to light the
turn indicator, and then make the turn. If your speed is too high, slow down before making the turn and start
the turn early. If you have to make a large turn, make the turn at a slow speed.
When turning the tractor tightly or on spongy-soft ground, you may experience some sideslip on the front
wheel. When this happens, step on the corresponding brake pedal and rotate the wheel to make the turn.
WARNING:
1.
2.
Never make sharp turns when the tractor is moving at a high speed, as this may cause the tractor to
become unstable.
Before making turns or backing up during field work, lift any implements from the soil to avoid damage.
25
Operation Instruction
2.8 Shifting Gears
16+8 Shuttle-Type Gear Shift
There are three gear shifts. The main and shuttle gear shifts are controlled by two shift levers on the driver’s
right. A T-handle on the right side floor controls the high and low range. The main gear shift lever A accounts
for 4 shifts (1 through 4), and the shuttle gear shift lever B has 2 forward speeds (FH for Forward High and FL
for Forward Low) and one reverse (R). The floor T-handle controls the High and Low range selection (H and L).
It works with all four gear selections, in forward and reverse.
Main Gear Shift Lever A
Shuttle Gear Shift Lever B
Figure 2-28 Tractor Gear Shift
Press the main clutch pedal to the floor and move the shuttle gear shift lever B to the left from NEUTRAL,
then push it forward to forward high gear FH. If you pull it backward, it will be in reverse gear R. Push it
to the right from NEUTRAL, then push it forward and it will be forward low gear FL.
Press the main clutch pedal to the floor and move the main gear shift lever A to the left from NEUTRAL,
then pull it backward to Gear 1. Push it forward to Gear 2. Move the main gear shift lever A to the right
from NEUTRAL then pull it backward to Gear 3 and push it forward for Gear 4.
With the 16+8 shuttle-type gear shift, there is a high/low speed T-handle on the center-right of the floor.
The central position is NEUTRAL. Pulling it up engages the Low range and pushing it down engages the
High range. Combined with the above main/auxiliary gear shift lever, you have 16 forward gears
and 8 reverse gears.
You should select the operating speed of the tractor based on getting optimum productivity and economy
and prolonging the service life of the tractor. When working, try not to overload the tractor. You should
always have a power reserve. When working in the field, the selected speed of the tractor should make the
engine load 80%. When the tractor does light-duty operations at a low speed, high shift 1 can be used to save
fuel oil by throttling down.
26
Operation Instruction
IMPORTANT ISSUES:
1. When running the engine, step on the main clutch pedal prior to shifting and wait for several seconds
before shifting to prevent improper clutch engagement and damage to the transmission.
2. Always step on the clutch pedal when shifting any of the three gear shifts.
3. Reverse cannot be engaged until the tractor is fully stopped as doing so can damage the gears.
4. When the tractor is running, never place your hand on the shift lever. The pressure of your hand can be
transmitted to gear shift fork in the transmission, causing the fork to wear.
2.9 Differential Lock Operation
If the tractor should become stuck or should one rear drive wheel
slip, you can lock the differential and connect the right and left rear
drive axles.
1. Step on main clutch pedal, and shift the high/low shift lever into
the forward low (FL) range.
2. Shift the range shift lever into low (L).
3. Move the throttle control lever to the high speed position.
Figure 2-29 Differential Lock Pedal
4. Step on the differential pedal to engage it.
5. Release the clutch pedal smoothly for stable operation.
6. After getting unstuck or stopping the skid, the differential lock will automatically release.
IMPORTANT ISSUES: When the tractor is running on normal surfaces, never use the differential lock.
This will help you avoid damage to components and reduce tire wear.
2.10 How to Use the Front Axle Drive
The NorTrac 82XTC 4-wheel drive tractor can be used for normal operations in the field and on wet and soft
soil. If only the rear wheels drive the tractor, the vehicle traction may not be enough for heavy-duty operation.
The front axle drive can be used to increase the traction and decrease slipping, improving the tractor’s
performance. In order to engage and release the front drive axle, use the following operational sequence.
Connecting the Front Axle Drive
Step on the main clutch pedal, engage the tractor in gear, and then release the clutch pedal slowly. After the
tractor moves a little, immediately pull the front drive axle control handle backward to change the two-wheel
drive into four-wheel drive.
27
Operation Instruction
Disconnecting the Front Axle Drive
To disengage the front drive axle, push downwards on the front drive axle handle.
IMPORTANT NOTES:
1.
Never use the front axle drive on a hard road surface. Doing so will result in early front wheel wear and an
increase in oil consumption. Only in rainy or snowy conditions, when the road is slippery or on a steep
slope, should the front drive axle be connected. Once clear of the dangerous road surface, the front drive
axle should be disengaged.
2.
When using the tractor for transportation, the front wheel tires tend to wear rapidly and left/right sides of
tire tread patterns wear unevenly. Because of this, you should exchange the left and right tires to maximize
their tread life.
2.11 Tractor Braking
2.11.1 Tractor Braking
Start by reducing the throttle, then step on the clutch pedal and then
gradually step on the brake pedal to stop the tractor. In an emergency,
step on the clutch and brake pedal simultaneously. Never step on the
brake pedal without disengaging the clutch, as this will cause sharp wear
to the brake pads and kill the engine. When connecting to a trailer brake,
adjust the length of the rod of the brake valve so that the trail brakes
Figure 2-30 Tractor Braking
before the tractor.
Interlocking the Left/Right Brake Pedals
When running on a road, lock the left/right brake pedals together with a lock plate.
2.11.2 Left/Right Brake Pedal Interlock
WARNING:
1. Prior to operating the tractor, check the oil level in the brake oil cylinder and the brake pipe for leakage,
and troubleshoot if necessary. This will help prevent a potential brake failure.
2. When driving the tractor on the road, the left and right brake pedals must be interlocked to prevent tractor
from pulling to one side when braking, and prevent a possible rollover accident.
3.
When the tractor is used on the road, lock both the left and right brake pedals together with the lock plate.
28
Operation Instruction
2.12 Stopping the Tractor and Engine Shutdown Procedures
1. Throttle down to decrease the tractor’s running speed.
2. Step on the clutch pedal and then the brake pedal. When the tractor stops, set the shift lever in to the
neutral position. The auxiliary shift lever (high/low gear range selector) and the shuttle shift lever
(forward and reverse) can be left where they are.
3. Release the clutch and brake pedal, and reduce the throttle so that the engine runs at idle.
4. Pull the fuel shut-off cable knob, which stops the fuel pump from supplying fuel to the engine.
The engine will stop.
5. Turn the starting switch key to the OFF position and shut down all power to the tractor.
NOTES:
1.
Never leave the tractor unattended with the engine running as this can result in a dangerous situation.
2.
When parking on a slope, the shift lever should be engaged (Shift Forward on uphill and Shift Backward
on downhill) to prevent the tractor from accidentally moving.
2.13 Tire Assembly and Disassembly
2.13 Tire Use

The tires are important parts of the tractor. Attention should be paid to their use and maintenance in order to
prolong tire service life.

All of the tires have specified load values. An overload will deform the tire. The sidewall will bend
excessively, and possibly rupture. The fabric of the tire body, as well as the cushion layer, also deforms
easily. The fabric layer will become loose until the tire ruptures. This is especially true when the road
surface is uneven or impacted by obstacles.

The inflation pressure of the tires must conform to the specifications. Service life is affected when the tire
pressure is too high or too low. If the pressure is too low, the tire will have excessive wear, and service life
will be limited. Both inner and outer tires will wear more rapidly when pressure is low. When pressure
is low, steering will be adversely affected. If the air pressure on the front tires is too low, steering will
be difficult. If tire pressure is too high, the tire body fabric will be stretched excessively and more apt
to rupture. The wear on the tire surface will be accelerated. The tractor vibration will be increased.
During field operations, the air pressure of the tire should be appropriately lower than when running on
29
Operation Instruction
the road. Tire pressure is best checked under normal temperatures. Checking a tire when it is hot can result
in an incorrect measurement. When driving the tractor, avoid jumping over obstacles at high speed, sudden
braking or quick turning. When driving on gravel, spinning the tires should be avoided, when possible.

During use, the tires should be kept clean of any oil, acid, alkaline chemicals or corrosives. Keep the tires
out of bright sunshine and excessive heat as much as possible to prevent the rubber from degrading.

The front wheel alignment and toe-in should be checked regularly. Failure to do so can result in excessive
tire wear. When tire wear is nonuniform, the left and right tires can be switched.
IMPORTANT ISSUES:
The inflation pressure for the front and rear tires on a 4-wheel drive tractor should be the same in order to
prevent the tires from being worn.
2.13.2 Tire Removal and Refit
Tire Removal
Special tools are needed to assemble and disassemble a tire. Contact a qualified tire service center to
replace tires.
WARNING:
1. When inflating the tire, never remove the lug nuts from the hub. This could cause the tire to fall off and may
result in damage to the tractor and serious personal injury.
2. Never disassemble the bolts connecting the tire, the hub and rim in the inflated state. The bolts may become
dislodged and cause an accident.
30
Operation Instruction
2.14 Counterweights
2.14.1 Rear Counterweights
When the tractor is performing field operations, different
counterweights can be used to raise the performance level,
according to the conditions. The rear counterweights are made of
cast iron, with each piece weighing 40 kg. (88 lb.), and you can
apply up to 6 pieces on a single side for 240 kg. (528 lb.) on
each side.

When plowing with a heavy load, you can mount 6 pieces of
cast iron for each side (optional).

For rotary tilling, you can mount 2 pieces of cast iron per side
Figure 2-31 Rear Counterweights
or go without counterweight (optional).

For common plowing operations, you could mount 4 pieces of cast iron per side.
WARNING: Before removing the rear wheel from the tractor, first remove the counterweight from
the tire to avoid an accident.
2.14.2 Front Counterweights
In order to adjust the front and rear axle loads of the tractor,
it is necessary to mount counterweights on the front of the tractor.
For plowing operations with heavy loads or towing large sowing
implements, you must mount enough front counter weight in order
to ensure the tractor can run safely without raising the front end.
The weight of the standard front counterweight frame is 57 kg.
(126 lb.).
You can select a maximum of 11 cast-iron front counterweight pieces,
each one weighing 22 kg. (48.5 lb.), for a maximum front
Figure 2-32 Front Counterweights
counterweight load of 242 kg. (534 lb.).
WARNING: For your safety, you must mount enough counterweight to avoid rolling over when
attaching large implements to the tractor.

Figure 2-34 Driver’s Seat Firmness Adjustment
NOTES:
1.
For safety, the seat should not be adjusted unless tractor is stopped and in park, to avoid an accident.
2.
Making the seat too soft can make running the tractor on uneven surfaces particularly challenging and
can cause a loss of sight lines.
2.16 Hydraulic Suspension, PTO, and Electrical System Operation
The Series 82XTC tractor uses a semi-separate hydraulic lifting system (3-point hitch) with two types of
adjustment modes: position adjustment and height adjustment. The control handle of the control distributor valve
is used to raise and lower farm implements. Push the handle forward to lower an implement; and pull it back to
raise an implement. See ―Hydraulic Lifting System Adjustment‖ for the adjustments to reach the maximum
raising position and the minimum lowering position.
A power output device (PTO) is used to deliver power to farm machinery. A swing traction device is used with a
harrow or a lawn mower.
32
Operation Instruction
2.16.1 Implement Position/Height Adjustment
When the tractor is pulling a cultivator or a plow, a 3-point lift is used to adjust the tilling depth. The tilling
depth is determined by the position of the lowering stop in the reset push rod, which adjusts the height from the
ground level to the plow bottom. When adjusting the stop on the 3-point lift, set the stop to the lower limit, and
put the 3-point lift control handle in the low position. When the farm implement is lowered to the required
depth (the adjustment method is shown in the Adjustment on the Hydraulic Lift System section), it will
operate at the tilling depth.
NOTE: Adjust tilling depth (draft) control according to implement specifications.
2.16.2 Farm Implement Lowering Speed Adjustment
Select a suitable lowering speed for the farm implement to keep it from being damaged by heavy impact when
it contacts the ground. Before delivery of the tractor, the descending speed regulating valve was adjusted.
The owner/operator can readjust the valve according to the weight of farm implement and ground hardness.

To decrease the lowering speed of the farm implement, turn the adjustment valve (A) clockwise.

To increase the lowering speed of the farm implement turn the adjustment valve (A) counterclockwise.

Operation Instruction
2.16.6 Adjustment of the Hydraulic Lift System
When plowing, in order to keep the tilling depth of all the
plowshares (blades) consistent from beginning to end, the
longitudinal and horizontal level adjustments need to be used.

Longitudinal level adjustment: Adjust the length of the
upper tie rod (A) to keep the plow frame level in the
longitudinal direction, so as to make the tilling depth of all
the plowshares the same. When the front plowshare is deep
and the rear plowshare is shallow or the heel leaves the
Figure 2-39 Suspension Mechanism
trench bottom, the upper tie rod should be lengthened. When the front plowshare is shallow and the rear
plowshare is deep or the heel compacts the trench bottom, the upper tie rod should be shortened.

Horizontal level adjustment: Adjust the length of the left and right lifting rods to keep the plow stock level in the
horizontal direction. If the right lifting rod (B) is lengthened, the tilling depth of the first plowshare will be deeper.
If the right lifting rod is shortened, the tilling depth of the first plowshare will be shallower. In general, the left
lifting rod (C) should not be adjusted. The left lifting rod is adjusted only when the adjustment of the right lifting
rod is not enough, so as to make the tilling depth of all plowshares the same.

Plowing Width Adjustment: Tilling width is adjusted mainly through the tilling width regulator. Front and rear
relative position for the left and right suspension points can be changed by lowering the plow width regulator.
The working width will then be increased when the right suspension point moves forward; otherwise the
tilling width will be decreased. You can adjust the device for the furrow width to ensure the plow frame is
aligned, which will help to avoid repeating or missed furrowing.
IMPORTANT ISSUES:
1. When plowing, never adjust the traction of the farm machinery by adjusting the limit rod. Instead, reduce the
number of plowshares (blades) to match the tractor’s pulling capacity. This will help you avoid damaging the
suspension mechanism.
2. In order to avoid damage to the implement suspension mechanism when plowing, the tractor should never be
turned without lifting the farm implement it is towing.
36
Operation Instruction
2.16.7 Sway Bar Adjustment
The sway bars are mainly used to prevent impact on the rear wheels of the tractor caused by an overlarge swing of
the lower tie rod when the tractor turns around at the end of a field with a lifted farm implement in tow. When the
farm implements are in the plowing position, the sway bars are in a loose state. Therefore, a certain amount of swing
between the tractor and the farm implement is allowed.
NOTE:
1. When moving the tractor and an attached implement over long distances, the height of the implement should
be adjusted to its lowest level by using the adjustable 3-point arm. The adjustable limit rod should also be
used to keep the machinery from swinging to the right or left during transpo rt.
2. The nuts for the adjustable 3-point arm and the limit rod should also be tightened to prevent wide swings of
the implement during transport.
IMPORTANT ISSUES:
1. When a fast change coupler is not used, the seat hole should be protected with the spare dust cover.
2. The lifter and the hydraulic output valve cannot be operated at the same time.
3. After setting up the auxiliary hydraulic output connection, the operating handle should be set in the neutral
position; otherwise, the hydraulic system could overheat.
4. The draft position control lever can control the 3-point hitch.
5. During the course of operation, only one lift handle should be used, and the other one set in the
lifting position.
WARNING:
Do not overload the tractor during traction operation or with a trailer. This can result in a loss of performance
and may shorten the service life of the tractor.
When braking, the trailer brake will apply slightly earlier than the tractor brake to prevent the load
from overturning.
37
Operation Instruction
2.16.8 Power Take Off (PTO) Shaft Use
To connect and disconnect power to the power take off (PTO) shaft the double-acting clutch, the PTO gear shift
handle, and the PTO disconnect control handle are used. When the clutch pedal is pushed down part way it
disconnects the engine clutch, and when it is pushed down all the way down it disconnects the PTO clutch. When the
PTO gear shift handle is pushed forwards, it will be in high gear. When the PTO handle is pulled backwards, it will be
in low gear. Use the following method:

Remove the rear hitch (only when using the 3-point configuration) and the protective cover on the power take off
(PTO) shaft and connect the farm implement drive to the PTO shaft on the tractor.

Depress the clutch pedal to the floor to disconnect the PTO clutch and put the PTO gear shift handle in the
required position (high or low).

Depress the clutch pedal to the floor again and turn the PTO disconnect control handle to the
―connected‖ position.

Release the clutch pedal slowly. First operate with the throttle at low speed to check whether the PTO is
working properly.

When repeated work in the same place within a short time frame is required, step on the clutch pedal gently to
disconnect the main clutch. This cuts off the power to the tractor transmission, and the tractor stays in one place
while the farm implement behind it can still
work normally.

To disconnect the PTO depress the clutch pedal
Figure 2-40 Power Output Device Operation
to the floor and turn the PTO disconnect control
1. High Gear
handle to the ―disconnected‖ position. The PTO
2. Neutral gear
3. Low Gear
gear shift handle does not need to be moved. The PTO shaft will stop turning.

After disconnecting the farm implement from the PTO shaft, reinstall the protective cover over the PTO shaft.
Replace the rear hitch if it had been removed.
WARNING:
Do not attach or detach anything from the PTO shaft while it is turning. Attempting to do so can result in equipment
damage and serious injury. When using farm machinery with a PTO, take care not to lift the farm machinery too high.
Too great of an angle between the PTO shaft and the farm machinery drive shaft can cause damage to the machinery.
38
Operation Instruction
2.16.9 Electrical Equipment Use
The electrical system of the 82XTC Series Tractor uses a 12V double wire system with a negative ground.
2.16.9.1 Battery
The battery is used to store the electrical energy produced by the alternator. The battery can then supply electrical
power to the electrical equipment on the tractor when the alternator is not turning or is running at low speed. It can
also help with the power supply when the alternator is overloaded for a brief period.

Frequently remove the dust and mud on the battery shell to avoid electric leakage. Check whether there are any
cracks in the battery case and/or leakage of electrolytes. Ensure good contact between the terminals and the
battery cables. The air vent on the plastic cover should not be blocked in order to avoid an explosion.

Frequently check the battery voltage. Charge it when the voltage is low.

The starter cranking time should not exceed 5 seconds each time to avoid excessive discharging.

If the tractor is not used for a long time, the battery should be removed for charging and maintenance.
2.16.9.2 Alternator

The alternator must be used with a matching regulator.

The silicon rectification alternator is minus ―—‖ grounded. The connection of the positive and negative poles of
the alternator, the regulator and the battery must be correct to avoid burnout of the alternator and the regulator.

Do not strike sparks to determine whether the alternator is generating electricity.

Remove the key from the ignition switch when the tractor is stopped to cut off the connection between the motor
and the battery and prevent the battery from discharging over an extended period of time.
2.16.9.3 Starter

The starter should not run for an extended period. The starting time should not exceed 5 seconds each time to
avoid damage to the starter.

If a grinding sound (teeth colliding) between the small gear on the starter and the flywheel ring gear is heard
when starting, turn the key back to its original position immediately and try again.

If the starter continues running after the key is back to its original position, shut down the engine immediately and
start again after the fault is remedied.
39
Operation Instruction
2.16.9.4 Auxiliary Electrical Equipment

The fuse box: has 15 fuses, total, 7 for normal use, and the others for spares. Fuses are used to protect
electrical equipment. Replace burned out fuses immediately. Each fuse’s rating should coincide with the
requirements on the electrical schematic. When a fuse burns out, it is necessary to troubleshoot the cause
immediately. Do not substitute a fuse with a higher or lower rating, as this can result in damage to the
electrical system.

The ignition switch is used to turn on the electrical system and preheat and start the diesel engine. Put the
key into the ignition switch, turn the key clockwise to the ON position and switch on the electrical system.
Turn the key further clockwise to H and switch on the engine preheater. Turn the key still further clockwise
to ST engage the starter. After the diesel engine is started, release the key and it will return to the ON
position automatically. During normal operations the key is always in the ON position. When the tractor
will not be used for a long time the key should be removed from the ignition switch.

Rear Trailer Socket: For powering the trailer taillights when the tractor is equipped with a trailer, the tractor
is equipped with a rear trailer electrical socket. For the socket wiring layout, please see Figure 2-42.

and raise and lower the mechanism 50 times or more.
2.19.5 Break-in—No Load
After break-in with the power output shaft and the hydraulic suspension, the entire tractor should be broke-in.
During idle break-in, make turns at low speed using the single-side brake and also test the emergency brake at
high speed. The break-in sequence and time required should be done in accordance with the specifications
defined in table 2-4.
While performing break-in operations, the rotary speed of the engine should be 1500 rpm. During break-in,
pay attention to the following:

Check to see if the electrical equipment and the readings for various instruments is normal.

Make sure that the engine is running normal.

Check to see that the clutch engages smoothly, and disengages completely.

Make sure that the shifting is easy and flexible and that it stays in gear.

Check the brakes for proper function.


3.1 Accessories
Tractor accessories include the heater, interior decoration, floor mats, AC, swing traction rod, etc.
3.1.1 Heater
The tractor cab heater is in the top front of the cab. There is a heater
switch on the heater that turns the heater fan on and off, in order to
ensure a comfortable working temperature in the cab. The engine
coolant supply valve must be turned on to use the heater.
When ventilation is needed in the cab, especially in the summer,
unheated air can be supplied by turning off the engine coolant
supply valve and turning on the fan.
Figure 3-1
Heater
The heater and the air conditioner both use four circular vents just inside the front window of the cab, and two
vents above the driver’s head. All the vents are located in the cab headliner.
3.1.2 Floor Mats
The floor mats consists of four pieces made of 10 mm. soft rubber. The mats are fixed on the floor with
plastic buckles. When removing, the floor mat can be taken up only after the button/snaps are pried up slightly
with a screwdriver. To put them back, place them in the original position and reapply the buckles.
3.1.3 Fender Gaskets
With applied PVC foam surface adsorption material and molding, the whole fender gaskets are fixed on to the
right and left fender by plastic buckles.
3.1.4 Swing Traction Rod
The swing traction rod is used for traction type farm implements.
The traction rod is connected to the farm implement with a traction pin.
The traction rod can swing both ways, which makes mounting farm
implements more convenient. However, when the tractor is towing a
farm implement backward, the positioning pin (1) must be inserted into
the hole of the traction plate, in order to stabilize the traction rod
(2) The traction point can be adjusted to the right height by turning
the traction rod, in order to connect the farm implement.

The air conditioner is located between the headliner of the cab roof cab roof panel. Air conditioner
controls are located on the left side of the headliner, above the driver. Air supply vents for the AC
unit are also in the headliner. The AC unit runs on tractor electrical power. The engine coolant
supply valve must be turned off before starting the air conditioner.
3.1.6 Cab Interior Light and Sun Shade
The cab includes an interior light above the front window. It is controlled by a switch on the light
and by the headlights switch. The sun shade is inside the front window, at the top.
IMPORTANT NOTE:
When the tractor is equipped with a heater or air conditioner, the engine cooling system must have antifreeze
at all times, in order to prevent the engine and cooling system from freezing or overheating. Use a 50/50
water/antifreeze blend.

4.3 Clutch Adjustment and Maintenance
4.3.1 Clutch and Operation System Adjustment
During clutch operation, owing to the wear of clutch friction discs and clutch plates, the clearance between the
clutch plate and the clutch fingers will gradually decrease. (Normal clearance is 2–2.5 mm.). Sometimes the
clutch fingers may contact the throwout bearing, eliminating clutch pedal free play, and the clutch will slip and
the throwout bearing will stick. In this situation the clutch should be checked and adjusted.
4.3.1.1 Clutch Pedal Free Play Adjustment
Unfasten the lock nut (1) counterclockwise and rotate
the clutch. The clutch pedal free travel is adjusted by
the vertical rod assembly (2) and should be 35–40 mm.
Make the clearance between the clutch fingers and
the throwout bearing 2–2.5 mm., then lock the nut (1) tight.
Figure 4-1 Adjustment on clutch pedal free path
1. Lock nut 2. Steering rod assembly
74
Maintenance Instructions
4.3.1.2 Clutch Fingers Adjustment
When the previous adjusement does not meet the requirements of
35–40 mm. of clutch pedal free travel, it means that the throwout bearing
has moved backward and is sitting tight on the carrier. The following
adjustment inside the clutch should be carried out:
1. Remove the inspection plate for the clutch on the transmission.
Figure 4-2 Inspection Plate Removal
2. Loosen the nut and adjust the screw for the clutch fingers with a wrench.
3. Make the clearance between the three clutch fingers on top of the clutch cover and the throwout bearing
2–2.5 mm. The three clutch fingers of the clutch cover should be on the same plane .
Their position tolerance should be less than 0.2 mm.
4. Tighten the lock nut after adjustment.
5. Check the clultch pedal free play to ensure that the stroke is within
the range of 35–40 mm.
6. Reinstall the inspection plate on the transmission.
Figure 4-3. Release Rod Adjustment
4.3.1.3 Main Clutch Release Travel Adjustment
1. There should be suitable pedal travel from the main clutch release to the auxiliary clutch release, to avoid
the auxiliary clutch releasing too early.
2. To obtain a suitable path, the clearance between the three adjusting
screws (2) on the main pressure plate of the clutch and the three
fingers (1) of the auxiliary friction discs pressure plate should be
1.7mm. Turn the adjusting screw and insert a feeler gauge to adjust the
clearance between the bolt head and the finger of the auxiliary friction
pressure plate so that it is 1.7 mm.

Maintenance Instructions
4.3.1.4 Tractor Overhaul Clutch Adjustment and Assembly

There is a group of crescent shaped spacers between
the clutch plate and clutch cover, as well as between
the engine flywheel and auxiliary (PTO) clutch.
During tractor overhaul, if the main/auxiliary friction discs
are seriously worn, you can take out some of the
adjustment gaskets to provide the disc spring
enough pressure.

When assembling the clutch, it can be sub-assembled on
the mandrel, then inserted into the flywheel bearing hole,
Figure 4-5 Tractor Overhaul Clutch
Adjustment and Assembly
to make main/auxiliary clutch friction discs concentric to the
spline hole, when mounting the transmission to the engine.
4.3.2 Clutch Maintenance
Check the clutch regularly to make sure that there is no oil leak in the split pin on the bottom of
the transmission. If any leaks are found, check the rear oil seal of the engine crankshaft, the seal on
the first shaft of the transmission, or the seal on the main power output shaft.
IMPORTANT ISSUES:
1. When using the clutch the clutch release should be rapid and complete, and the engagment should be soft
and smooth, in order to avoid damage to the clutch.
2. To avoid clutch damage when the tractor is running, never rest your foot on the clutch pedal, or ride the
clutch to reduce the tractor’s running speed. Never engage the clutch suddenly to accelerate over a barrier
or up a slope.
3. Make sure there is no oil on the surface of clutch friction discs. If oil is found, remove it with solvent and
allow the discs to air dry, in order to avoid damage to the clutch.
4.4 Transmission Adjustment and Maintenance
The transmission usually needs no adjustment during operation. The following information should be noted
during
the operation and maintenance of the tractor.
76
Maintenance Instructions
4.4.1 Checking Transmission and Rear Axle Differential Oil Level
The transmission and the rear axle differntial share the same oil sump.
The sump uses a transhydraulic oil. The position of the oil filling port
on the lifter case is shown in Figure 4-6.
When checking the oil level, the tractor should be parked on a
level surface.
After shutting down the engine, remove the oil level dispstick on
Figure 4-6 Transmission Oil Level
the rear end of the rear axle, wipe it clean, then reinsert the dipstick.
If the oil level is lower than the low oil level line, lube oil should be added until the oil level is between the high
and low level marks. Check the oil level 5 minutes after the engine has been shut down.
4.4.2 Changing Oil in the Transmission and Rear Axle Differential
When changing the lube oil in the transmission and rear axle differential
the drain plug (1) in the transmission should be removed to completely
drain the used oil. Replace the oil drain plug, and fill with fresh lube oil.

the power output (PTO) shaft and the operation mechanism.
77
Maintenance Instructions
4.5.1 Rear Axle Maintenance
The main drive/driven spiral bevel gear pair for the center drive should be replaced as a matched set.
When applying the differential lock, the tractor should be driven in a straight line and steering wheel cannot
be operated, otherwise, it will cause mechanical damage.
NOTE:
When operating the tractor in reverse, the operation handle for the power output shaft (PTO) should be put into
neutral to avoid damage to the farm implement.
4.6 Brake Adjustment and Maintenance
There are two disc brake assemblies, which are symmetrically mounted on the right and left shafts of the rear axle,
and connected with the brake operation mechanism.
4.6.1 Brake Pedal Free Play Adjustment
When the brake pad assembly and the brake drum are working correctly,
the clearance betweeen them is 1–1.4 mm., and the corresponding brake
pedal free play is 90–120 mm.
When the brake pads are worn, the brake pedal free play will increase,
resulting in poor braking.
When this is the case, the brake pedal free play must be adjusted.
Figure 4-9 Brake Pedal Adjustment
1. Lock Nut 2. Adjustment Rod
Adjustment Method:
Loosen the lock nut (1) on the adjustment rod (2) and turn the rod.
The brake pedal free path will be decreased or increased depending on the direction you turn the rod.
The right and left pedal free path should be adjusted to be the same. The lock nut (1) should be tightened
after adjustment.
4.6.2 Right/Left Braking Force Adjustment
The braking force of the right and left brakes should be consistent. Usually when emergency braking
on a paved surface, the tire trace of the right and left drive wheels should be the same.
Adjustment Method: Loosen the two lock nuts on the brake rod, adjust, and retighten the two nuts.
78
Maintenance Instructions
4.6.3 Brake Use and Maintenance
If there is oil or dirt on the surface of the brake pads, it should be cleaned with solvent and re-assembled after
it has dried. Regularly check the wear of the oil seals on the brake casing and cap. Change them, if necessary.
WARNING:
The right and left brake pedal free play should be adjusted to be equal. Otherwise, when emergency braking,
the tractor could sway and cause a rollover or accident.
To be safe, test the brakes after any brake mechanism adjustment. The procedures is as follows:
1. Interlock the right and left brake pedals.
2. Drive the tractor on a dry, flat road.
3. Run the tractor in a straight line and use the emergency brake after releasing the main clutch.
4. Check the tire skid marks on the road surface.
5. If the skid marks of the right and left drive wheels on the road are consistent (in a straight line and parallel)
then the brake adjustment is good..
6. Otherwise, readjust if necessary. If it is still not good even after repeated adjustment, the brakes should be
thoroughly checked.
4.7 Steering Mechanism Adjustment and Maintenance
The tractor uses a separate hydraulic steering system consisting of a
cycloid rotary valve, a full hydraulic steering gear, a steering oil
cylinder, an oil tank, a track rod, a constant and overflow pump, and
oil lines. Never adjust the steering during use. During maintenance, it
should be noted that the constant and overflow pump, oil tank, steering
oil cylinder and oil inlet/outlet of the steering gear, as well as
Figure 4-10 Steering Mechanism
the oil line joints should be checked and tightened, in order to avoid oil leaks.
If you encounter an oil leak, check the gaskets and make sure that none of the seal rings are damaged.
Replace if necessary.
79
Maintenance Instructions
IMPORTANT ISSUES: The safety overflow pressure for the overflow valve on the constant current
overflow pump has been set before delivery. It should not be removed and adjusted without Nortrac approval.
After repair, loosen the two fittings on the oil cylinder and run the oil pump at a low speed to bleed any air from
the oil, then tighten the fittings.
4.8 Four-Wheel Drive Front Axle Adjustment and Maintenance
The tractor front axle can be divided into three chambers: the central oil chamber, the left end drive oil chamber
and the right end drive oil chamber.
4.8.1 Four-Wheel Drive Front Axle Central Oil Chamber Drain and Fill
The central oil chamber is in the middle of the front end of the tractor.
The oil level should be checked regularly from the sight glass. When the
oil level is low, oil should be added until the oil reaches the top line on the
sight glass. When changing the engine oil , unscrew the oil drain plug from
under the front axle and completely drain the used oil. Then, replace and
tighten the oil drain plug. Put fresh lube oil into the oil filling port Figure 4-11 Front Axle Central Oil Chamber

to align the plug and the front wheel horizontal center line. Fill with fresh oil and
reinstall the fill plug.
4.9 Transfer Case Adjustment and Maintenance
The oil drain plug for the transfer case is on the side of transfer case. The used oil from the transfer case can be
completely drained through this plug.
80
Maintenance Instructions
4.10 Tire Adjustment and Maintenance
Tires are one of the main consumables of the tractor, and should be carefully used and maintained in order
to extend their working life as long as possible.
Improper operation will cause the tires to wear out too soon or be damaged during normal operations.
During operation, avoid going over obstacles at high speeds and emergency stopping or turning. When driving
on a rough road, avoid tire slippage if at all possible.
During use, the tires should be kept clean of oil, acid, alkaline, chemical corrosives and out of direct sunlight as
much as possible, in order to keep the rubber from aging and degrading. The front wheel alignment and front
track also need regular checking, in order to avoid uneven tire wear. You can switch the right and left tires when
wear is uneven.
4.10.1 Tire Inflation
Tire air pressure should be kept according to the regulations.
Four-Wheel Drive Type: Both the front and rear tires are inflated to 0.11–0.14MPa (16-20 psi).
When the drive wheel slips you need to shut down the tractor and troubleshoot immediately.
Do not run at high speed on uneven or rough roads. Operate the emergency brake as little as possible.
You can switch the right and left tires when the tire threads are unevenly worn.
The tires should be kept clean of fuel, lube oil or other dirt. When dirty, wash or brush them with water.
When the tractor is not going to be run for a long period, it should be jacked up to take pressure
off of the front tires.
NOTE:
Excessively low or high tire pressure will shorten the service life of the tires. It will affect steering and control
of the tractor, and could lead to hazardous situations.
81
Maintenance Instructions
4.11 Electrical System Adjustment and Maintenance
The tractor electrical system uses a 12V, single-wire, negative ground system. The system consists of the engine
starting equipment, lights, instruments, and signal devices.
The engine starting equipment includes the starter, alternator, battery, voltage regulator, and ignition switch.
For the operation and maintenance of this equipment, refer to the diesel engine instruction manual.
The lighting and signal devices include the headlights, rear lights (with top rear lamp for cab), turn signals, and
taillight set (turn signals, position and brake lights), combined instruments, speakers and fuses, etc.
The fans and controls for the cab HVAC system and the air conditioner compressor are also electrical.
4.11.1 Battery
The battery is in the front of the tractor, as shown in Figure 4-13.
Figure 4-13 Battery Position
4.11.2 Battery Maintenance
Normally the maintenance-free battery does not require any special maintenance. Water does not have to be
added to maintain the level of electrolyte since the battery is sealed. You can observe the power levels from the
view hole in the battery: Green = full power; Grey = lack of power; Dark = no power.
As part of the tractor’s electrical system the battery requires some system level maintenance.
1. Check the status of the battery. Make sure the case is not cracked or leaking, and the battery is secured
in place.
2. The battery should be charged under the following conditions:

The engine is slow to start and/or the lights are faint.

The inspection hole becomes grey. It should be replaced when the inspection hole becomes dark.

The battery is under voltage. Measure the terminal voltage when discharging. There is a problem with
a 12V battery if the output voltage is lower than 10.5V.
3. When being stored, the battery should be charged monthly. The charging method is as follows: charge the
battery by 0.1C20A (C20 is power capacity for 20hrs.). When the terminal voltage for the 12V battery
reaches 14.4±0.05V, you can continue charging for another 5hrs.
82
Maintenance Instructions
4. When removed from the tractor for any reason, the battery should be stored in a clean, dry and
well-ventilated area with a temperature that is 32–104F. The battery should be handled with care and
stored right side up.
5. The power supply should be tightly connected to the battery terminals, in order to prevent the terminal from
melting when the tractor is started. In order to avoid terminal oxidation or corrosive, the exterior of
terminal should be coated with petroleum jelly or corrosion preventative spray.
6. Keep the exterior terminals of the battery clean.
7. Check the voltage regularly to make sure that the regulator is working properly. The voltage for the
regulator is 14.2.1±0.2V.
Check the generator output voltage regularly. The voltage should be 14.2±0.25V.
NOTE:
1. When charging the battery, keep it in a ventilated area and far from open flames. When charging is over,
shut off the power in order to avoid a fire or explosion.

4.12 Hydraulic Suspension System Maintenance
The tractor’s lifter has been properly adjusted at the factory and there is no need for the user to do it again.
But during use, the adjusted state can change, which will impact the normal operation of the tractor because
of wear and loosening of the bar driver pair.
When the force-adjusted spring assembly is mounted, the regulating washer may be used for adjustment,
which doesn’t allow clearance on the spring after mounting.
4.12.1 Control Handle and Feedback Lever Adjustment

Install the lifter on the tractor, connect the hoses and fill the
hydraulic oil reservoir.

Mount the suspension bar and hang a load of approximately
200-300 kg. at the lower suspension point. Place the control
handle in the lowest position.

Start the engine and set the throttle in the neutral position.
.
Fig.4-20
Hydraulic Suspension System

Slowly move the control handle up and the lift arm
and load will rise. When the handle reaches its peak, the
angle should be 53° between the lift arm; the level is normal.
If the angle between the lift arm and the level is less than
53°, it should be adjusted.

When the angle between the lift arm and the level is
less than 53°, the bolt (1) on the feedback lever can be used
toincrease the length of the feedback lever until it conforms
to the requirements.

Tighten the nut (2) after adjustment.

Maintenance Instructions
4.12.2 Hydraulic System Use (only for a double acting oil cylinder type system)
When the control handle is pushed from the N position to the front
position, the suspension system will start to rise. When reaching the
deadline position, the control handle will move back automatically
(i.e. back to the N position).
When the control handle is pushed from the N position to the reverse
direction (at such time, the control lever is not in the rear position,
the suspension system will descend. Once you release the control handle,
it will go back to the N position, the descent will stop.
When the control handle is pushed from the N position to the lowest
position, the suspension system stays in the “floating” state after
dropping down to the final position.

4.12.3 Lifter Height Limiter Procedure (for a double-acting oil cylinder system)
4.12.3.1 Lifter Height Limiter Function and Structure Diagram
You can control the lift height of farm implements by adjusting the position of the limitor (see adjustment
procedure). Refer to the Figure 4-23 and make any adjustments as per the procedures described, to
prevent breakage of the PTO shaft caused by the farm implement being lifted too high.

86
Maintenance Instructions
4.12.3.2 Height Limiter Adjustment Method and Requirements

Shown above, you can control the height adjustment by adjusting the limit push board on the right side of
lift shaft. Remove the nuts (1 and 2). The more the limit push board is adjusted counter-clockwise the
higher the adjustment. Adjusting clockwise will lower it.

Farm implements must be raised up when turning while doing field operations. It is required that the farm
implement has a ground clearance of 150–250 mm. after lifting. This can be achieve through setting the
length of the limit push board.

When making adjustments for long distance operations or road transportation:adjusts the position of the
limit push board; the farm implement’s lift height must have over 250 mm of ground clearance.

Tighten the fixture parts after adjustment.
IMPORTANT ISSUES: When adjusting the distance between the position clamp ring block and the
position valve, the adjustment of both the oil cylinders should be maintained in conformity with a tolerance of
0–0.5 mm. This will prevent damage on the farm implement parts.
4.12.3.3 Hydraulic Suspension System Oil Use and Maintenance

The lifter cover is on the oil tank of the hydraulic suspension
system. International standard hydraulic oil should be used
according to the environment.

Check every 50 hours to see if the oil level in the lifter cover is
within the oil level stick range.

Clean up the breather regularly. To do this, open it, take out
the filter, clean it with solvent and blow it clean with compressed
air. Replace it with a new filter elements when it

Maintenance Instructions
4.12.3.5 Oil Filter Maintenance
After every 100 hrs. of tractor operation, check the hydraulic
suspension system filter (1) and clean the filter element.
The maintenance method is to turn the cover at the back end of
the oil filter, take out the filter element, clean it with solvent
and blow it dry with compressed air.
Replace it with a new filter element when it is difficult to clean
or it is broken.
Fig.4-25
Hydraulic Oil Filter
1. Oil Filter
4.13 Air Filter Use and Maintenance
The interval for air filter maintenance should be based on
the dust conditions in which the tractor operates. When the
dust is heavy, service is recommended every 8 hrs.
When the air filter is blocked, a visual alarm on the filter
housing turns red, and the air filter must be serviced.
Every day, or when refueling, check the air filter to ensure
Fig. 4-26
Air Filter
that all of the joints between the air filter and engine are well
sealed, including all of the hose joints and the air filter housing.
When replacing the filter element, remove the wing nut and washer and carefully remove the element from
the housing. Take care to prevent dust from falling into the filter housing. Use a clean, moist cloth to wipe the
inside of the filter housing and the used safety filter element surface prior to reinstalling the filter element.
Do not use compressed air to clean up the filter housing.
Repair any holes immediately and log the repair into the machine service and maintenance record.
Dispose of any damaged filters and replace with a new filter. Use the cover, washer and wing nut to tighten
it
down. Ensure that the filter rubber washer is mounted between the wing nut and filter element, and that the
intake resistor is installed. Ensure that the end cover position and seat are aligned prior to putting on the end
cover and fastening the clamp ring or wing nut.
IMPORANT ISSUES:
1. The proper use and mantenance of the air filter is vital to the service life of the engine. It must be
kept clean.
2. Never rinse the filter element with water or solvent as this can damage the filter element.
88
Storage
5. Storage
When the tractor is going to be out of use for an extended period of time (more than one month) it should be kept in
a proper storage building. The storage facility should provide protection from the elements so as to keep the tractor
clean and prevent rust and corrosion.
Before storing the tractor it must undergo a thorough cleaning and adjustment and tightening of various parts,
subject to the technical maintenance requirements based on the duty hours, so that the tractor remains in good
technical condition.
IMPORTANT ISSUES: During long periods of non-use it is very important to preserve and maintain the
tractor. If special steps are not taken, the life of the tractor could be shortened and parts could deteriorate.
5.1 Tractor Storage - Causes of Damage

Rust: During the storage period, dust and moisture in the air get into the tractor. This can cause
contamination and rusting of the components. When pistons, valves, bearings and gears stay in one
place for an extended period of time, they lose lubricant film protection, which produces rust and
causes parts to stick and seize up.

Aging: Some components are made of with rubber and plastic parts, which will age and deteriorate,
getting brittle and rotting, under the ultraviolet rays in sunlight.

Deformation: Components such as drive belts and tires may become distorted in shape if left in the
same place for too long.

Others: Electrical parts are affected by damp conditions, and the battery can discharge over time.
5.2 Tractor Storage

Prior to storage inspect the tractor and its surroundings to ensure that the tractor can be stored safely.
The external surface of the tractor should be cleaned.

Remove the battery, coat the terminals posts with petroleum jelly, and keep it in dark, well -ventilated
room with a consistent moderate temperature.

Drain the engine oil while it is hot and fill with new engine oil. Run the engine for 10 minutes at idle
to allow the new engine oil to adhere to the surfaces of all the moving parts evenly.

Add lubricant to all the various lubrication points.

Coat the electrical contacts, connectors and all unpainted metal part surfaces with anti -corrosion spray.
89
Storage

Loosen the fan belt on the engine and remove it if necessary. Wrap the belt(s) securely and spray the
pulley groove with a rust-proof agent. If possible, paint over all chips in the paint and cover
non-painted metal parts with a rust inhibitor.

Drain diesel fuel from the fuel tank or add diesel fuel conditioner to the fuel tank.

Seal any engine opening such as intakes/outlets with protective material to prevent foreign matter,
dust, and moisture from getting in.

Place all control handles in the neutral position (including electrical system switches and the
parking brake).

If possible, prop the tractor on blocks so that the tires are free of weight. Check the tire pressure on a
regular basis.

The tractor should be parked in a dry, well ventilated area. If such an area is unavailable, cover the
tractor with a waterproof covering. Never store the tractor around flammables or corrosive materials.

Any parts removed from the tractor should be cleaned, packed and stored in a dry place.
5.3 Tractor Storage Maintenance

Check on the tractor and its parts at least once a month to see whether there is any rust, corrosion,
aging, or distortion happening. Immediately make any necessary repairs.

Start the tractor twice a month and allow the engine to run. This will prevent interior rust.

If possible, drive the tractor once every three months at low speed for 20-30 minutes. This is a great
way to see how the tractor is doing in storage.

Clean the dust off the top of the battery with a dry cloth, and check the charge level. The battery can
go dead even when not in use. Recharge the battery once a month.

When transporting the tractor long distances by train, truck, or trailer the gears should not be engaged.
Transporting the tractor with the gears engaged, will move parts such as the gears, bearings, crankshaft
and pistons, which can rub without lubricant and cause damage.
IMPORTANT ISSUES: If you cannot carry out the anti-rust treatment and the tractor needs to be out of use
for several months or longer, at a minimum, replace the machine oil and oil filter. Start the tractor once every
month and run the tractor at low speed for 20–23 min. at a minimum. Check to make sure everything is operating
properly and keep the tractor clean to limit the amount of corrosion that could result from dust and wet conditions.
90
Storage
5.4 Removing Tractor from Storage

Remove any grease used for anti-rusting.

Reopen the various sealed up nozzles and clean the tractor.

Check coolant, machine oil, and diesel fuel and lubricate all of the lubrication points according to
the provisions.

Remove any anti-rust agent in the belt grooves and reinstalls and/or adjust th e belts.
(See: Engine Instruction for Use and Maintenance)

Reinstall the battery and check the terminals.

Check that all of the circuits, hoses and lines are properly connected.

Check air pressure in tires.
NOTE: Please refer to the ―Engine Instruction for Use and Maintenance‖ for details on engine storage and
removing tractor from storage.
91
Transportation
6. Transportation
If the tractor is to be driven by the owner, local traffic regulations should be strictly observed with at
least 180 feet of distance maintained between vehicles. If the tractor is being transported, the following
procedures should be followed:
1.
A smooth, level spot should be selected for loading and unloading the tractor. A special unloading
platform should be used if one is available.
2.
Have one helper available for guiding and make sure the area is clear of everyone else.
3.
After loading, the lift should be placed at the lowest position, the hand brake set, the reverse gear
engaged, the ignition switch turned off, and the key taken out.
4.
The front and rear tires should be fixed in place with straps in a figure 8 pattern. Both front and rear
tires should be blocked and the rear axle secured with straps.
5.
The tractor should be pulled inside an enclosed trailer or moved to the center of a flatbed trailer as far
as possible and the rear view mirror may be taken down when necessary.
6.
When tunnels and bridges are encountered, full attention must be paid to the load height, and
speed should be adjusted for road safety.
7.
While unloading, the hand brake should be released first. The drive gear should then be engaged an
the tractor should be unloaded slowly and carefully at the lowest tractor speed.

IMPORTANT ISSUES:
1. Before choosing the farm implements, you should refer to this detailed list and base your decision on the
working conditions (requirements of soil resistance, agronomy and so on) of the area. Choose the categories
of supporting implements and then consult the distributors.
2. According to the purchased model of the tractor (power capacity) in combination with the working conditions
(requirements of soil resistance, agronomy and so on) of the working area, you should refer to the results of
the consultations to determine the models of farm implements you need for suitable support. If the supporting
equipment is not suitable, it will have an adverse impact.
3. Different working conditions (requirements of soil resistance, agronomy and so on) with the same working
efficiency of the implement can give different results. Please calculate the working speed, working width etc.
according to local working conditions.
