Warning
symbol
This symbol has been used throughout
these operating instructions to highlight
all sections relevant to your safety. Also
pass on all safety instructions to other
users.
Intended use
The machine meets the current state of
the art and complies with the applicable
safety regulations at the time of market-
ing within the context of the approved
use. In terms of design it was not possi-
ble to eliminate either the foreseeable
misuse or the remaining risk without
limiting the functionality in accordance
with the regulations.
The brush mower agria 8000 is de-
signed exclusively for cutting thin, non-
woody brushwood, grass and similar
plants in agriculture, forestry, green area
and grounds maintenance. The lower
rotating mower disc must slide on the
ground. However, it is not suitable for

trary to the intended purpose. The man-
ufacturer is not liable for any damages
resulting from such use and the risk is
entirely the user's own.
Intended use also includes observance
of the operating, servicing and mainte-
nance conditions stipulated by the man-
ufacturer.
Unauthorized changes to the machine,
especially to the safety equipment, may
lead to increased levels of danger, which
would rule out any manufacturer liability
for resulting damage.
When using the machine on public roads
– and when being transported – the
national road traffic regulations of the
relevant country must be complied with
(marking, lighting, etc.).
The machine is intended to be used in
commercial and in private applications.
The machine must be operated as di-
rected in the operating instructions.
Other operators must given instruction if
required.
Any improper use or execution of activi-
ties of the machine not described in
these instructions constitutes unauthor-
ized misuse and is not within the statuto-
ry limits for liability of the manufacturer.
Improper use of the machine can en-
danger people and may result in dam-
age to the machine or other property of
the operator. It can also impair the func-
tionality of the machine.
Reasonable foreseeable misuse
Foreseeable misuse and improper han-
dling include inter alia:
•Removal or manipulation of protec-
tive and safety devices
•Working on steep slopes without
securing the operator, the machine
and the working area
•Transport and manoeuvring move-
ments with activated knife drive
•Failure to observe maintenance
intervals
•Omitting measurements and tests
for the early detection of damage
•Failure to replace wearing parts
•Incorrectly executed maintenance or
repair work
•Improper use.

General safety and accident
prevention regulations
Basic rule:
Please observe the relevant accident
prevention regulations as well as the
generally recognized rules pertaining to
safety, occupational health and traffic
laws.
The use of public transportation routes is
subject to the Road Traffic Act in its
latest version.
Please check the traffic and operating
safety of the machine before each com-
missioning!
The machine may only be used, ser-
viced and repaired by persons who are
familiar with it and have been instructed
in the hazards involved.
Persons under the age of 16 must not
operate the machine!
Only work with good visibility and in
good lighting conditions.
Operator clothing must fit tightly. Wear
sturdy footwear.
When operating the machine, wear
protective goggles to protect the eyes
from small flying parts!
The affixed warning and information
signs provide important information for
safe operation; please observe them for
your own safety!
The engine must be switched off for
transport on motor vehicles or trailers
outside the working area.
Be careful with rotating tools - keep a
safe distance!
Be careful with coasting tools. Before
you start working on them, wait until they
have come to a complete stop!
There is a risk of crushing and shearing
on power-operated parts!
Riding on the implement during opera-
tion is not permitted.
Match the operating speed to the condi-
tions.
Do not adjust the setting of the engine
speed governor. A high speed increases
the risk of accidents.
Working area and danger zone
The working area is the entire area to be
worked on. The user is responsible for
third parties in the working area.
Staying in the danger zone of the ma-
chine is not permitted (see page 26).
Check the work area before starting and
moving. Pay special attention to children
and animals.
Before starting work, remove foreign
bodies such as stones, wires, pipes,
thick branches from the surface to be
worked on. Foreign particles can be
ejected or damage the mowing equip-
ment. Look out for additional foreign
objects while working and remove these
promptly.
For operation in enclosed areas, ensure
that a safety distance is kept from edges
to prevent damage to tools.
Operation and protective de-
vices
Before you start work
Familiarize yourself with the equipment
and operating elements and their func-
tions. Above all, learn how to turn the
engine off quickly and safely in an
emergency!
Ensure that all protective devices are
mounted and properly adjusted!
Before each start-up check the function-
ing of all parts and protective devices.
Replace any damaged parts - have this
done by a specialist workshop if neces-
sary. For your own safety, only use
original Agria spare parts.
Suitable shoes must be worn depending
on the type of ground surface (vegeta-
tion, humidity ...), so that the operator
does not slip or fall.

Safety Instructions
Brush mower agria 8000 11
Startup
Do not start the engine in closed rooms,
the exhaust fumes contain carbon mon-
oxide, which is very toxic if inhaled!
Before starting the engine, set all operat-
ing elements to neutral or idle position.
Do not step in front of the machine or
the add-on device to start the engine.
Operation
Never leave the operator's position at
the steering bar while working!
Never adjust operator bars while work is
in progress – risk of accident!
For all work with the device, especially
when turning, the machine opera-
tor must maintain the distance from the
device shown by the bars!
Riding on the implement during opera-
tion or in transport is not permitted.
If any blockages occur on the cutting
unit, stop the engine, take off the ignition
plug or ignition key, and clean the cut-
ting unit with a suitable tool. There may

3 Devices and Operating Elements
The brush mower agria 8000 is de-
signed exclusively for cutting thin, non-
woody brushwood, grass and similar
plants in agriculture, forestry, green area
and grounds maintenance. The lower
rotating mower disc must slide on the
ground. However, it is not suitable for
lawns in parks! (Intended use)
When using the machine on public roads
– and during transport – the national
road traffic regulations of the relevant
country must be complied with (marking,
lighting, etc.).
Engine
The four-stoke petrol engine is to be
used with standard petrol (see chapter
Startup, page 25).
During the first 20 hours of operation
(running-in period) do not use the engine
at full power.
The rule of never using the engine at a
higher speed than necessary for the
work in hand applies even after the
running-in period.
High speeds are detrimental to
all engines and significantly reduce
their service life. This especially ap-
plies for no-load operation! Over-
revving the engine (letting it roar) can
result in immediate damage.
Cooling
The engine is cooled with an air blower.
Keep the fan grille at the cable-pull
starter and the cooling fins of the cylin-
der free of dirt and aspirated plant de-
bris.
Idling
Always ensure that the engine idle
speed is adjusted correctly. With speed
regulating lever at idling, the engine
should continue running smoothly.
- agria-Service -
Air filter
The air filter cleans the aspirated air. A
contaminated filter reduces the engine
output.
Ignition system
The petrol engine is equipped with a
contactless electronic ignition system.
We recommend that any necessary
inspections are carried out by a skilled
person only.

Speed regulating lever
(Engine stop switch)
Use the speed regulating lever (A/3, B/3) at the
steering bar for operating the CHIKE and the
engine stop switch as well as the continuous
speed control. Switch positions see fig.
Safety circuit
The machine is equipped with a safety circuit for
mowing and driving.
O Stop position:
When the safety lever (A/1 or
A/2) is rele
ased, the drives are switched off, and
the engine continues running.
I operating position:
For operation, press down
the safety lever (A/1 or A/2). This establishes a
frictional connection between engine and gear-
box.
Never tamper with the safety circuit.
Never tie up the safety lever.
The safety lever is used as an
emergency
off switch:
Release the lever in a dangerous
situation. It swings automatically to "STOP"
position!
