Main table of contents
The Operator’s Manual is divided into 11 main parts, using the numbers 1, 2, 3 ... 11. These are further sub
divided into number sections. There are four levels of titles. E.g. on the marking 4.1.3 the letter 4 tells that
it is the main part 4, Instruments and controls. The first number 1 (see detailed table of contents) tells that
it is the illustration section of the instruments and controls part, etc.
The detailed table of contents provides a lettering, a numbering and page system. The bottom of each
page displays a reference to the main part of the manual it is in.

To the operator
HATTAT A70, A80, A80L, A90, A100, A110
(Models sold may vary in different marketing areas)
This Operator’s Manual is primarily intended for the driver. The manual contains detailed instructions for
driving and maintaining the tractor. Make sure that your new tractor is always handled and maintained in
the correct way which will keep it reliable and provide economical operation for many years. In certain
marketing areas the whole model range are not sold.
This Operator’s Manual is only for agricultural tractors. If the tractor is used as a traffic tractor, it must fulfil
the requirements of local traffic regulations. In this case always contact your HATTAT dealer first.
In this booklet, information which refers to more than one model is given as
(e.g.A70/A70L/A80/A80L/A90/A100/A110).
Alternative equipment in the book means equipment, which can be selected when buying. This equipment
can not easily be fitted at a later time to the tractor. Extra equipment means the equipment, which can be
bought and mounted at a later time to the tractor.
We recommend that you read the manual thoroughly. Follow the maintenance program carefully and add
the daily maintenance to your normal routine.
Maintenance, repairs and adjustments which are not described in this Operator’s Manual require the use of
special tools and exact technical data. For such work you should contact your dealer who has specially
trained personnel to help you.
Only use original genuine spare parts for optimum performance from your tractor. You should order spare
parts according to the spare part dealer.
Due to the continual development of HATTAT Inc. products, the content of this manual may not always
correspond with the new product. Therefore, we retain the right to make alterations without prior
notification.
Please note: when using the tractor you must always follow all valid laws and regulations even, if they have
not specifically been pointed out in this manual.

2. Safety precautions
2.1. Safety rules
This section summarizes the regulations which must
always be followed when working with the tractor.
However, these regulations do not exempt the
driver from following statutory and other national
regulation as regards traffic safety and occupational
health and safety.
Safety regulations applicable for different types of
working sites and existing road traffic laws must
always be followed.
When designing the tractor priority was given to the
safety of the operator. Steps and handles have
been placed with ease of entry into the cab in mind.
The tractor has several safety features egg: guards
for belts and pulleys etc.
1. Tractor construction − The tractor
construction must not be changed (f.ex. max.
driving speed, max. power etc.) The tractor is
type approved to comply with construction and
use regulations. Any changes to the tractor may
reduce the safety and durability and affect the
warranty terms.
2. Brakes − Always check that the brakes are
operating correctly before setting off. The brake
pedals should be locked together when driving
on the road. The brakes should be adjusted as
necessary. Extensive repairs to the braking
system should be undertaken only by HATTAT
approved service personnel. When implements
or ballast weights are front end mounted the
rear axle loading is decreased:
− In these circumstances the driver should
check that the rear brakes are still effective.
− When needed use opposite ballast weights at
rear.
3. Children and tractor − Never allow children in
the cab or near the tractor or attached
implement while the engine is running. Always
lower the implement to the ground when leaving
the tractor.
4. Passengers − No passenger may ride on the
tractor unless it is provided with a special seat.
Other personal transport, for example, on front −
mounted loaders, is not permissible.
CAUTION!
Hold on to the steering wheel
or safety handles in the cab if
the tractor tips over.
Never try to jump out.
5. Caution − Hold on to the steering wheel or
safety handles in the cab if the tractor tips over.
Never try to jump out.
6. Maintenance − The driver is responsible for
following the maintenance instructions in this
Manual and the safety regulations applicable for
the tractor. No maintenance work is to be
carried out on the tractor or implement unless
the engine is stopped and the implement
lowered.
7. Lending − Never lend the tractor to a person
who is not used to driving it. You may be held
responsible for any resulting accidents.
8. Lights − Always make sure that the lights and
reflectors are clean and in working order. Do not
forget that the headlights must be correctly
adjusted.
9. Carbon monoxide − Never start the engine, or
run it indoors while the doors are closed as this
may lead to poisoning by carbon monoxide.
10. Downhill − Never drive downhill with the
gear lever in neutral or the clutch pedal pressed
down. Check the brakes often. The brake pedals
should be locked together when driving on the
road. Always change down to a lower gear
before driving down a steep incline.
When driving downhill do not brake
continuously danger of overheating the brakes!
Do not let the engine go into overdrive, it may
damage.
11. Running speed − Adjust the speed to suit the
driving surface, visibility and load. Avoid any
sudden increase or reduction (braking) in the
running speed as well as tight turns at high
speed. If care is not taken the tractor may tip
over or the load may be displaced.
CAUTION: The maximum speed of the tractor
must not be altered.
Maximum operating forward speed is 40 Km/h,
for safety the maximum operating speed in
reverse is 20 Km/h.
12. Power take − off driven attachments − When
running with power take off driven attachments
or machines it is very important that the
prescribed safety devices are used and that they
are in good condition.
Serious accidents have occurred due to failure
to use prescribed safety devices. Follow the
directions given by the implement or machine
manufacturer.
13. Check links − When transporting implements
on the three − point linkage, the check links
must be locked with the locking pins.

10
14. Emergency exits − The cab is provided with
three emergency exits. These are the doors,
rear window and roof.
15. Trailer load − On tractors with trailers the
load must be properly secured. The load must
not obstruct the driver’s vision or cover lights
and reflectors. Loads wich project more than 1
m (39 inch) behind the vehicle train must be
suitably marked. During day time this is
done with a flag and during darkness with a red
light and reflector arrangement.
16. Trailer − A trailer should only be coupled to
the drawbar. A loaded drawbar must always be
lowered with the three − point linkage. Check
that trailer brakes are operating property and
observe any special instructions issued by the
trailer manufacturer.
CAUTION: When the tractor is towing
a trailer the brake pedals must be
locked together. The brakes are not
to be used individually for steering.
Loads wich project more than 1 m (39 in) behind
the vehicle train must be suitably marked.
CAUTION: When using a trailer make
sure that the hitch latch is locked.
WARNING: When using the trailer
always use the brakes, if the law
requires.
17. Front − end loader − When working with a
frontloader be sure that no one is in the working
area. There is a danger that the tractor may tip
over when the loader is lifted. The driver should
put the front end loader in the down position
before leaving the tractor.
Any special instructions issued by the loader
manufacturer should also be observed.
18. Running − Before driving, always check that
the tractor is in a safe condition for driving on
the road. Rear view mirrors should be adjusted
for the correct viewing angle before setting off.
When towing an implement whose centre of
gravity is located at a signifi cant distance
behind the tractor, the driver should remember
that there may be considerable sway during
cornering.
19. Differential lock − The differential lock must
only be used when driving on loose or slippery
ground. Never turn on a firm surface with the
differential lock engaged. The differential lock
should be disengaged when cornering.

section.
21.. Front axle loading −
When driving on the road
at least 20 % of the gross
weight of the tractor must
be on the front axle. When
lifting an implement the
weight on the front end of
the tractor is reduced, and
the steering ability of the
tractor is impaired or
sometimes lost.
Therefore sufficient ballast weights should be
carried. Ballast weights should be mounted only
at the points intended for this purpose.
22. Attaching implements − Care must be taken
when implements are being attached. There is a
risk of an accident if the tractor or implement
should move. It is only safe to enter the
implement if the parking brake is applied or the
wheels blocked in order to prevent the tractor
from moving.
23. Damage − The driver is responsible for
seeing to the repair of any wear which might
endanger the safety of the tractor.
CAUTION: If damage occurs to the
cab, all parts affected should be
replaced with new ones. No repair
work (welding, drilling, cutting, or
grinding) should be attempted.
24.. Triangle for slow vehicle (SMV − Slow
Moving Vehicle) − When driving on public roads
always use use the rotating light where required
by law .
25. Hydraulic/fuel pressure − Oil/fuel under high
pressure easily penetrates through clothing and
skin and can cause serious injury. Never
attempt to locate a leak in the hydraulic system
or attempt to close a leak using any part of your
body.
26. Implements maintenance − Implements
connected to the linkage or the auxiliary
hydraulic system must be lowered to the ground
during maintenance.
27. Motor noise − When you are operating the
engine or working near it, use hearing
protectors to avoid noise injuries.

smoking and sparks are prohibited near the fuel
system and batteries. (Especially, when
charging batteries, explosive gases present).
29. By a fire − At temperatures in excess of 300°
C, e.g. if the engine is on fire, the viton seals of
the engine (e.g the undermost 0 − ring of the oil
pressure regulating value) produce very highly
corrosive hydrofluoric acid. Do not touch with
your bare hands, viton seals which have been
subjected to abnormally high temperatures.
Always use neoprene rubber or heavy duty
gloves and safety glasses when decontaminat−
ing. Wash seals and the contaminated area with
10 % calcium hydroxide or other alkali solution.
Put all the removed material in sealed plastic
bags and deliver them to the point stated by the
Authorities concerned.
NOTE: Never destroy viton − seals
by burning!
30. Engine stop and restart − If the engine has
stalled eg. due too heavy loading, turn the
ignition switch to the STOP position. Restart the
engine according to the starting instructions.
Keep an eye on the indicator lights on the
instrument panel.
31. Quick couplings for lower links − Clean, if
necessary the quick couplings and ball joints for
the lower links before attaching the implement.
DANGER OF THE IMPLEMENT RELEASING!
32. .Hazardous substances EN 15695-1:2009
DANGER: The cab is classified as
category 1 according to the draft of
EN15695-1:2009. Protection against
dust or hazardous substances
(agricultural chemicals, etc.) is not
provided. Personal protective
equipment must be used according
to the chemical manufacturer’s
recommendations.
33. Falling Object Protection Structure (FOPS)
According to this traktörlerde the OECD code 10
(Falling Object Protective Structure) (FOPS) feel there
is no Protective Structure That Household.
DANGER: Make sure the protection is
adequate for your work conditions.

12
34. Operator Protection Structure (OPS)
These tractors that preserve structures are not in
accordance with EN ISO 8148: 2003.
DANGER: Before operating, make
sure the protection is adequate for
your work conditions.
2.1.1. Roll Over Protective or Cab.
Structures
A Roll Over Protective Structure (ROPS) and seat
belt (extra equipment) is fitted as standard
equipment to the footstep tractor at the time of
factory assembly. If the ROPS was removed by the
original purchaser or has been removed, it is
recommended that you equip your tractor with a
Roll Over Protective Structure and a seat belt.
ROPS are effective in reducing injuries during
overturn accidents. Overturning a tractor without
ROPS can result in serious injury or death.
If a fold down ROPS is installed DO NOT wear seat
belt when the ROPS is in the folded down position.
1. Sun Protection Roof (Optional
acessory)
- Keep rollover protective structure fully extended
- Do not jump if machine tips.
- Use seat belt.
- Whwn structure must be down.
- Do not use seat belt.
- Drive with extra care.
− Before using the tractor ensure that the ROPS
frame is not damaged, that it is securely fastened to
the tractor and if a hinged section is fitted that it is in
the raised position and secured.
− If the ROPS has been removed from the tractor,
or folded down for a specific operation, it must be
refitted or erected immediately afterwards using the
proper hard ware and applying the recommended
torque values.
− DO NOT attach chains, ropes, or cables to the
ROPS for pulling purposes; this will cause the
tractor to tip back wards. Always pull from the
tractor drawbar.
− Always wear your seat belt − adjusted snugly
except when operating with a folded down ROPS.
− Check the seat belt for damage. A damaged seat
belt must be replaced. (Fig)
2. Prevent Machıne Runaway
Avoid possible injury or death from machinery
runaway.Do not start engine by shorting across
starter terminals.
Machine will start in gear if normal circuitry is
bypassed.
NEVER start engine while standing on ground. Start
engine only from operator’s seat, with transmission
in neutral or park.
3. Servıce Tractor Safely
Do not service the tractor while it is in motion or
while the engine is running.
When servicing front-wheel-drive-equipped tractor
with rear wheels supported off ground and rotating
wheels by engine power, always support front
wheels in a similar manner. Engaging front-wheel
drive will pull rear wheels off support if front wheels
are not raised.
Tighten wheel hardware to correct torque as
specified in Wheels, Tires and Tread section.
Torque at intervals shown in Break-In Period and
Lubrication and Maintenance sections, to ensure
that wheel hardware does not loosen.
Reinstall shields removed during service.

13
4. Handle Fuel Safely—Avoıd Fıres
Handle fuel with care: it is highly flammable. Do not
refuel the machine while smoking or when near
open flame or sparks.
Always stop engine before refueling machine. Fill
fuel tank outdoors.
Prevent fires by keeping machine clean of
accumulated trash, grease, and debris. Always
clean up spilled fuel.
5. Freeıng A Mıred Machıne
Attempting to free a mired machine can involve
safety hazards such as the mired tractor tipping
rearward, the towing tractor overturning, and the
tow chain or cable failing and recoiling from its
stretched condition.
Back your tractor out if it gets mired down in mud.
Unhitch any towed implements. Dig mud from
behind the rear wheels. Place boards behind the
wheels to provide a solid base and try to back out
slowly. If necessary, dig mud from the front of all
wheels and drive slowly ahead.
If necessary to tow with another unit, use a long
chain or cable. Inspect the chain or cable for flaws.
Make sure all parts of towing devices are of
adequate size and strong enough to handle the
load.
Always hitch to the drawbar of the towing unit.
Before moving, clear the area of people. Apply
power smoothly to take up the slack: a sudden pull
could snap any towing device causing it to whip or
recoil dangerously.
6. Removıng Materıal From A Pıle Wıth A
Grapple
IMPORTANT: Using the grapple teeth to dig
material out of a pile will damage the grapple or
loader. The grapple is designed only to
clamp material in a bucket. Use the
bucket to break material loose.
1. If possible, remove material from the top of the
pile first.
2. Use loader bucket to break material loose. Equip
the bucket with tines for better loosening action in
packed material.
3. After material is loosened, close grapple.
7. Tow Loads Safely
Stopping distance increases with speed and weight
of towed loads, and on slopes. Towed loads with or
without brakes that are too heavy for the tractor or
are towed too fast can cause loss of control.
Consider the total weight of the equipment and its
load. Observe these recommended maximum road
speeds, or local speed limits which may be lower:
Ensure the load does not exceed the recommended
weight ratio. Add ballast to recommended maximum
for tractor, lighten the load, or get a heavier towing
unit. The tractor must be heavy and powerful
enough with adequate braking power for the towed
load. Use additional caution when towing loads
under adverse surface conditions, when turning,
and on inclines.
8. Boarding And Leaving Tractor

14
From right and left hand side of the tractor there are
2 steps existing. Use these steps for boarding. Use
the same steps incase of leaving the tractor.
9. Use A Safety Chain
A safety chain will help control drawn equipment
should it accidentally separate from the drawbar.
Using the appropriate adapter parts, attach the
chain to the tractor drawbar support or other
specified anchor location. Provide only enough
slack in the chain to permit turning.
10. Safely Transportıng The Tractor
A disabled tractor is best transported on a flatbed
carrier. Use chains to secure the tractor to the
carrier. An operator must steer and brake the tractor
under tow.
When jacking a tractor
•Jack on a flat, hard surface, ideally a
concrete floor.
•Avoid working alone. Ask somebody with
training and experience to assist you.
•Refer to the manufacturer's manual on safe
jacking procedures, or seek the advice of a
competent person.
•Where jacking points are not identifiable,
jack from the lowest possible point on the
frame or axle housing.
•Use jacks that comply with applicable
standards.
•If using jack stands, only use stands that
comply with applicable standards, and are
designed and rated for the load to be
suspended.

3.2 Service
In order to function satisfactorily the tractor must be
properly maintained.
The necessary daily lubrication and routine checks,
can, of course, be carried out by the driver.
Where adjustments and repairs are necessary
which require the attention of a qualified mechanic
and the use of special tools, it is advisable to relay
on a workshop. In this case we advice you to
consult your local dealer as to how your tractor
should be looked after as he is in a position to give
you the best possible service. Through service
bulletins and special training courses he is kept
constantly informed of the factory’s
recommendations regarding care of the tractor.
3.2.1. Cost-free service
Before leaving the factory the tractor was thoroughly
tested and adjusted to ensure it is in first-class
condition when delivered to you.
However, it is important that the tractor is given
further checks during the first period of operation.
Bolts must be checked for tightness, various
settings inspected and other minor adjustment
made. Your dealer therefore gives one cost free
service inspection (excluding oil and filter costs)
after 100 hours running.
3.3. Engine
(Please check the Perkins engine manual )
The tractors have 4 − stroke direct injection diesel
engines
The principle of the turbocharged engine is that
exhaust gases from the engine cylinders drive the
turbo unit which forces air into the cylinders. This
means that a higher power output can be obtained
with economical fuel consumption.
3.4. Power transmission
3.4.1 Clutch
The clutch is of the double type
and is attached to the engine
flywheel. There are separate
discs for the propulsion clutch
and power take − off. Both
clutches are operated
mechanically independently of
each other, the propulsion
clutch being controlled by
means of a pedal and the power take − off clutch
with a lever. The clutch plates are both axel and rad
springed.
3.4.2. Gearbox
HATTAT tractors have two type of
gearbox(16+8,12+12)The main speed gear are has
four synchronized gears which are controlled with a
speed gear lever. In front of the gearbox there is
fitted a shuttle unit or splitter unit that is changed
according to 16+8 or 12+12.
On models with the shuttle unit the gearbox has
three range gears; LL=creeper range, M=Medium
range and H= High range. M and H ranges are
synchronized. All these three range gears are
controlled with one lever. In the gearbox there are
12 forward speeds and 12 reverse speeds.
On models with the splitter unit the gearbox has two
range gears; L=Low range, H=High range and
R=Reverse speed. Two range speed and R are
controlled with one lever. Two range and R speed
are syncronized.
The gearbox has a common housing with the
differential. Helical gears of the gearbox give a low
noise level and vibration less power transmission.
The gearbox also has pressurized lubrication
provided with an oil filter.
3.4.3. Rear axle
The rear axle is fitted directly to the gearbox.
The differential lock is of the coupling type which is
engaged and disengaged electro − hydraulically. An
indicator lamp on the instrument panel lights up
when the differential lock is engaged.
Final drives are of the planetary gear type. From the
planetary gears power is transmitted to the rear
wheels.
3.4.4. Mechanical Shuttle&Splitter
The shuttle unit is synchronized and has a pressure
lubrication system. The forward reverse shuttle is
controlled with the lever nearest to the driver. For
this reason forward/reverse changing can be made
by stopping the quickly and very easily.
