Important Instructions about the Engine
Important instruction about the ( Massey Ferguson) tractor
engine :
12
Optimum performance of the engine depends on its proper use and good maintenance.
Proper selection of engine speed and gears is essential for proper use.
Proper selection of engine speed and gear can reduce the diesel expense up to 15%.
Since the engine continues to consume diesel when running without being used,
do not keep the engine running idly for longer periods of time. It is better to shut off the
engine and restart when needed again.
It has been commonly observed that 75% of the tractors malfunction or breakdown
prematurely due to carelessness in maintenance.

Changing the Engine Oil
13
Changing the Engine Oil Of Massey Ferguson Tractors :
The most important task in maintenance of the tractor is changing the engine oil on time.
Change the oil according to the prescribed schedule in the maintenance booklet.
Check the engine oil level daily before starting work.
There are two marks on the dipstick; MIN is written on one and MAX at the other.
The engine oil level should never be less than MIN or higher than MAX.
The tractor must be parked on a level plane when checking the oil level.
When changing the oil follow the instructions given in the booklet for changing the oil;
change the oil filter as well.

Engine Temperature
15
Engine Temperature of Massey Ferguson Tractors :
The designated temperature of diesel engine is 80 to 85oC. To maintain this temperature,
there is a valve called ‘thermostat’ in the engine. Never detach it from the tractor under
any circumstance.
Engine parts have been manufactured to operate at a specific temperature,
and the engine may be harmed if the temperature falls under or rises above this
temperature. Commonly the inexperienced or ill trained mechanics remove this valve
from the engine, which cause the engine to operate at cold temperature.
Engine operation at low temperature causes faster wear out of the piston rings and
liners, and soon the engine becomes useless.
Experiments have demonstrated that operating the engine at 40o C instead of 80oC
wears out the piston rings twice as fast. Meaning, the service repairs commonly need
after four years becomes necessary after just two years.
Moreover, the cold engine operation increases the diesel consumption by 5%.

Running-in and Driving the Tractor
17
Method of Running-in the Tractor :
– Do not drive the tractor to farm or home immediately after taking delivery. Have it carried
on a truck instead.
– Operate tractor at 75% load from the beginning. Prior to this, drive the tractor in 3rd gear
and at full depth in an already ploughed field
– If a trolley is to be pulled then 75%, then the trolley could be filled with weight up to 75%
of its capacity. After using the tractor for the first 30 hours, have the nearest dealer or
authorized workshop service the tractor for the first time.
– Very Important :
Under no circumstance operate the tractor empty (without load), nor keep the engine
running idle for long periods of time.
How to Operate the Tractor ?
1- Press the clutch pedal completely with your foot, shift the tractor in first gear, and
select the smaller levers (Low or High) as needed.
2- Release hand brake.
3- Now increase the engine revolution slowly with the help of foot throttle and
simultaneous release the clutch slowly until fully released and your foot is off it.

Maintenance of Radiator and Oil Cooler
19
Maintenance of Radiator and Oil Cooler in Massey Ferguson
Tractors :
Just like the radiator, to cool the oil with air, there is an oil cooler installed in the MF260.
In the MF375S/385/385 4WD, oil is cooled with an oil cooler that uses water instead of air.
Oil Cooler MF-260 Oil Cooler MF-385/385 4WD
The radiator and oil cooler grills in the MF260 should be checked frequently. If foreign
object / debris is found stuck on them; clean with compressed air or water with less than
100 Psi pressure.
When cleaning the grills, make sure the side panels are removed so the dust and debris
stuck on them could find a way out. Always use the air / water pressure from behind the
grills, so the garbage could be pushed out from the front. Never use diesel to clean the
grills. Simple soapy water is enough for cleansing.

Checking the Radiator Water Level
21
Checking Water Level of the Radiator in Tractor :
– Before checking the water level in the radiator, it is very important to have the tractor
engine turned off; because removing the radiator pressure cap quickly when the engine
is hot, the gushing boiling water may harm you.
– Remove the radiator cap with the bonnet flap raised up. If the water level is low, then fill
up with normal drinking water.
– If water change is needed, remove the drain plug located at the bottom right side of the
radiator.
Importance of the Radiator Cap :
The radiator is a very important part of the temperature maintenance system. There are
two valve-springs in the cap. One of the valves lets out the steam from the heated water
and the other allows external air in, so vacuum is not created during the cooling process
after engine is turned off. Commonly due to lack of knowledge about importance of the
radiator cap, when the tractor’s original one is lost or broken, the owners replace it with
any common cap that fits. This is harmful for the engine.
Very Important (Instructions for the Cold Climates)
If you use the tractor in a cold climate, then is very
important to use the anti-freeze is used according
to the instructions, or drain the water from the
radiator at night and refill with fresh water in the morning before operating the
tractor.

Checking the Fan-belt Tension
23
Checking the Fan-Belt Tension of MF Tractor :
Fan-belt being loose or overly tightened may become a reason to overheat the engine
and damage the alternator. Therefore, it is necessary to have the fan-belt tightened to
proper tension. To check the tension, pressing the longer portion of the belt (between
the alternator and crankshaft pulley as shown in the picture) with a force of approximately
10 pounds should loosen the belt 10mm or ⅜ of an inch.
In case of improper tension in the belt, loosen the alternator and adjusting link nuts, and
by pressing the alternator with the help of a lever, tighten the bolts after adjusting the
belt’s tension. Check the tension again after tightening the bolts.
Very Important :
Always use belts of correct size.
Do not use any kind of oil or grease to mount the belt.

Importance of Air-cleaner and Maintenance
25
Importance of Air Cleaner and its Maintenance :
Air cleaner that appears unimportant plays an important role in reducing or increasing the
engine life. If it is not cleaned in timely, dust particles enter the engine and mix with oil and
grease to work as sandpaper to wear out the engine components. A clogged air filter
becomes a barrier for air, which reduces the engine strength and increases the diesel
expense by 10%. In order to conserve diesel and optimum performance of the engine, it
is very important that the air cleaner is cleaned on a regular basis. There are two parts of
the air cleaner :
1. Pre-Air Cleaner
The air cleaner is covered by a bowl, which is called the Pre-Air Cleaner. It catches the
dust, dry grass, hay, etc and collects in the clear plastic bowl. The pre-air cleaner must
be removed and cleaned everyday.
Very Important
Never pour oil in the pre-air cleaner bowl under any circumstances.

a. Air-Cleaner body (which contains a permanent filter)
b. Filter Element
c. Oil Bath
Oil is filled in the oil bath up to
the specified mark. Filter element
is placed over it, and then oil bath
is fitted with the air-cleaner.
When the air coming through the
pre-air cleaner makes contact with
the oil in the oil bath, the oil passes through the filter element up to the permanent filter
in the air-cleaner body, due to which the filter becomes covered with oil. The dust
particles in the air flowing through stick to the oily filter, and the cleansed air enters the
engine cylinder. Gradually, the oil becomes dirty due to this process.
Daily before use, remove the oil bath to check the oil level and its condition.
If the oil is below the required level, then fill the bath with more oil. If the oil is thick with
dust, then empty the oil, remove oil bath, air cleaner body, and filter element to clean
thoroughly with kerosene. After cleaning refill the oil bath up to the mark and attach to
the air-cleaner.

How to Change the Diesel Filter
28
How to Change the Diesel Filter in Tractor ?
Diesel filters are placed on the left side of the tractors. The glass cup filter is called the
‘primary filter’ and the other one is called the ‘secondary filter’. Check the primary filter
daily, if you find water or dust in the diesel then manually open the drain tap under the
glass cup to drain the dirty diesel. Stop cock of the diesel tap must be open during while
draining the diesel. Daily cleaning of the diesel this way protects important and expensive
parts like fuel injection pump and atomizers.
Before installing the diesel filter, first and foremost it is important to close the diesel tank’s
stop-cock.
Remove the small bolt on top of the filter body with the key provided, and separate the
filter. Replace the small rubber ring with a new ring. Similarly after replacing the two bigger
rings place the new diesel filter and tighten the bolt.
Open the diesel tank’s stop cock, manual restore the diesel supply in the fuel line by
pumping the priming lever of the fuel lift pump.
Very Important
Change the diesel filters regularly on timely basis and use only genuine filters. Never use
polluted oil.

Air-lock and How to Remove it
31
Air Lock and how to Remove it from the fuel system of tractor ?
If air somehow enters fuel system of the tractor, it stops the fuel-supply and in turn stops
the engine. This is called ‘engine is air-locked’. It is important to remove this air from the
fuel system before restarting the tractor.
1. Reason for Air-Lock
– Empty diesel tank.
– Closed diesel stop-cock.
– Choked / closed fuel filters.
– Loose fuel pipes, nuts and bolts.
2. How to Remove the Air-Lock
– Tighten all pipes and nuts of the fuel system.
– First open the upper Vent Plug of the primary fuel filter and pump the fuel lift pump of
the priming lever, so that airless diesel starts to flow. Close the Vent Plug.
– Now loosen the two screws on the fuel injection pump and keep moving the priming
lever until diesel without air bubble begins to flow out. First tighten the lower screw and
then the upper one.
– First loosen high pressure pump of the cylinder’s the automizer.
– Start the tractor with the key and tighten the high pressure pipe as the engine sound
becomes clearer/ stable.

How to Fill the Diesel Tank
33
How to Fill the Diesel Tank of Massey Ferguson Tractor ?
Always use uncontaminated diesel; i.e. that does not contain sand, water, kerosene, and
other unnecessary elements, because these ruin the costly and delicate parts of the fuel
injection pump and automizer which deteriorate engine performance.
To protect the parts described and described above, it is important that you refill the diesel
tank after completion of work. Refilling the tank will decrease air in it. The less air in the
tank will create fewer water vapors, and the parts will be safe from harm. Never mix oil in
the diesel.

How to Store Diesel
34
Storing the Diesel :
If diesel is to be stored in drums, then tilt the diesel filled drums as shown in the picture
below. Front end of the drum must be 3 to 4 inches higher than its rear end, so that all
unwanted deposits like sand, rust, dust settle at the back end, and clean diesel comes out
from the front.

Checking/Changing Transmission and Hydraulic Oil
35
Checking and Changing the Transmission and Hydraulic Oil for
tractor :
– To chech the transmission oil, it is important to park the tractor is parked on a level
surface and turn off the engine.
– Remove and clean the small gauge (dipstick) under the driver seat with a cloth.
– Reinsert and remove the gauge and hold it tilted to check the oil level. In case of low
level, replenish the oil.
– If you plan to use the tractor only to plough or pull trolleys, then maintain the oil level
anywhere in the zone marked on the gauge as XX, as shown in the picture labeled ‘B’.
if you wish to use the oil in the gearbox to operate any external instruments, for example
front blade and tipping trolley etc, then in that case the oil mark should be at the ‘Max’
level ‘C’; as shown in the figure.
Very Important
– You must have the transmission oil changed after hours from a reputable workshop.
– Not changing the oil allows the iron dust, mixed with the oil, to ruin the gearbox and the
hydraulic system parts.
– After the first 600 hours, have the transmission oil changed by a recognized workshop.
– Changing the hydraulic oil after completing every 600 hours, and clean the hydraulic
pump filter with diesel.
– MF240/350 has a capacity of 33 liters for the transmission/hydraulic oil, whereas
MF260/375/385 can hold 36 liters, and MF385 4WD reservoir can hold 42 liters.
– For external hydraulic components in the MF240/350, the oil capacity is 36 liters,
whereas 39 liters in MF260/375/385, and 45 liters in MF385 4WD.

Hydrostatic Power Steering System
37
Hydro-Static Power Steering System :
This system is installed in the MF385/385 4WD tractors, which allows the driver/operator
to control the steering system with ease. Hydro-static power steering system is a complete
power steering system in which there is no mechanical connection between the steering
wheel and the front wheels, which allows the steering wheel to be turned with only one or
two fingers. This tractor is especially suitable for working with front-end loaders.
In this oil system is supplied to the steering control unit through steering pump, due to
which controlled quantity of oil reaches the right and left sides by the steering cylinder
when the steering wheel is turned; and when the steering wheel is straight, the steering
unit bypasses the oil supply.
NOTE:
Always use the reputable and reliable oil in MF350/260/375/385/385 4WD Tractors
7
Chapter 19
Hydrostatic Power Steering System
38
A. Neutral Oil Flow When Tractor is Moving Straight :
This is the neutral position of the steering unit. In this position the oil flows from the
hydraulic pump to the steering unit, and because of the oil spool and sleeve hole being in
straight position the oil returns to the steering pump. In this system two shock valves and
two suction valves are fitted on the right and left sides of the steering unit. Shock valves
are used between the steering rim cylinder and steering ring control unit to protect this
system, whereas the suction valves are used to compensate any shortage of oil in the
system.
7
Chapter 19
Hydrostatic Power Steering System
39
B. Turning of the Steering when the Engine is Running :
On first movement of the steering wheel the right and left turning holes become straight
with each other, so that oil can be supplied to the oil hand pump. Subsequently, the
second movement turns the steering and the hand pump. Simultaneously, the hand pump
measures the quantity of oil and pushes it back towards the spool and sleeve. The oil
coming back enters the spool valve through the grooves, which connect the holes together
straightly so that the oil could go to the direction in which the steering wheel was turned.
With the spool valve and sleeve holes being face to face with each other, the oil coming
back from the steering cylinder returns to the circuit. The relief valve between the inlet and
the spool inside the steering unit, which protects against the high-pressure created inside
the pump, for example, due to an obstruction while the front wheels are turning. From the
steering pump to the steering unit, there is a check valve installed on the way. This is a
one-way valve that prevents high-pressure while the steering is being turned.
C. Turning the Steering when the Engine is OFF :
The pump stops working when the engine is turned off, due to which the oil starts to pass
through a bypass valve installed inside the steering unit between the supply and return
holes. As the pump starts to function, the oil pressure shuts off the valve by pushing it onto
its seat.
When the pump cylinder is low, the oil returning from the steering cylinder towards the
valve inlet side is bypassed. With the help of this function, the oil can move from one side
to the other inside the steering cylinder to maintain uninterrupted steering control.

Battery Maintenance
42
Battery Care of Massey Ferguson Tractor :
Maximum benefit can be obtained from the battery by following the instructions
described below.
– The tractor battery should never be used without the ‘bracket’; otherwise the battery could
be damaged. Secure the battery clips tightly.
– If there is white or blue substance on the battery terminals, wash the terminals with warm
water and dry; and apply some petroleum jelly.
– Remove all Vent Plugs of the battery and then look in each cell to see whether the plates
are submerged in the battery solution or not. If not, then fill with distilled water up to the
‘Max’ point.
– Before replacing the caps, check to make sure the Vent Holes on them are not closed;
because the battery could be harmed if the holes are closed.
– Never use hammer or heavy object to push wire clamps on the terminals. Otherwise, the
battery will be ruined very soon.
– The battery wires should never be loose. Otherwise, starting the tractor will be difficult.
– Replace the faulty wire and/or clamps
Often farmers leave the engine running during meal breaks when the battery is weak,
which wastes a lot of diesel. The tractor battery should always be well charged, because
high power is required to start the engine. If the battery does not have the required power,
the engine starts with difficulty, which also wastes diesel.

Air Pressure in the Tyres and its Importance
44
Proper Air Pressure in the Tyres and its Importance :
In order to get proper performance out of the tractor, proper air pressure in the tires is very
important because engine power is wasted when the air pressure is low or high and
required productivity is not obtained, either. It is important for every tractor owner to have
an air gauge and a manual air pump handy.
Improper air pressure can cause the following harm:
– Tire life is reduced and these crack at the sides.
– It causes unnecessary load on the engine which overheats the engine.
– The tractor emit smoke and does not pull well.
– Diesel consumption is increased and time is wasted as well.
– Parts of field remain un-ploughed.
– Rear tires slip during operation, which causes more wear out.
Use the instructions below to maintain proper air pressure in Massey Ferguson tractors :
7
Chapter 22
Air Pressure in the Tyres and its Importance
45
VERY IMPORTANT :
If there is additional load on front part of the tractor, like front-end loader or front blade is
used, inflate the front tires to 40 psi. Using oil or grease to clean the tires reduces their life.
Water is sufficient to clean these.

Method and Benefit of Filling Water in Tyres
46
Benefits of Filling Water in the Tyres and its Method :
The probability of tires to slip increases when the tractor is light and is operating on hard
ground. It reduces the performance, which cause increases diesel consumption.
Experiments show that proper tire grip on the surface, tractor performance increases by
10 to 25 percent.
To increase the surface grip in the rear tires, filling water in the tires is recommended.
Below is the method to fill water in the tires with a simple instrument.
Water Can Be Filled In the Tyre Using the Instrument :
1- Raise the rear tires with the help of the jack, and raise the inflation valve to its highest
