1 Safety Instructions
Before commissioning, please read the
operating instructions and note:
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 us-
ers.
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 possible
to eliminate either the foreseeable mis-
use or the remaining risk without limiting
the functionality in accordance with the
regulations.
The agria 5300 meadow mower is
a manually guided, self-propelled, single-
axle machine which can be combined
with cutter bars and accessories that are
approved in the Agria sales list. The
meadow mower is designed exclusively
for cutting grass and similar plants and
thin, non-woody undergrowth in agricul-
ture and forestry as well as for the
maintenance of green areas and parks.
After attaching the clearing blade, which
is also included in the Agria sales list, it
may also be used as a snow clearing ma-
chine (intended use).
Any other use is considered to be con-
trary to the intended purpose. The manu-
facturer is not liable for any damages re-
sulting from such use and the risk is en-
tirely the user's own.
Intended use also includes observance of
the operating, servicing and maintenance
conditions stipulated by the manufac-
turer.
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 na-
tional road traffic regulations of the rele-
vant country must be complied with
(marking, lighting, etc.).
ATTENTION: Never use the machine on
public roads with a trailer. The approval
requirements are not fulfilled.
A trailer for operation with the two-wheel
tractor is not included in the Agria sales
program. An expertise to obtain an indi-
vidual homologation (to German §21
StVZO) for the two-wheel tractor is not
available from the manufacturer.
Any unauthorized combination of the two-
wheel tractor with a trailer excludes any
liability of Agria.
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 re-
quired.
Any improper use or execution of activi-
ties of the machine not described in these
instructions constitutes unauthorized
misuse and is not within the statutory lim-
its for liability of the manufacturer.
Improper use of the machine can endan-
ger people and may result in damage to
the machine or other property of the op-
erator. It can also impair the functionality
of the machine.
Reasonable foreseeable misuse
Foreseeable misuse and improper han-
dling include inter alia:
•Removal or manipulation of protec-
tive and safety devices

General safety and accident
prevention regulations
Basic rule:
Please observe the relevant accident pre-
vention regulations as well as the gener-
ally 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, serviced
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 op-
erate the machine!
Only work with good visibility and in good
lighting conditions.
Operator clothing must fit tightly. Wear
sturdy footwear.
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 out-
side 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 operation
is not permitted.
Driving behaviour, steering –and possi-
bly –braking capability and tipping be-
haviour are influenced by attached or
suspended devices and loads. Therefore
ensure adequate steering and braking
capability.
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 31).
Check the work area before starting and
moving. Pay special attention to children
and animals.
Foreign objects are to be removed from
the area to be worked on prior to starting
work. Look out for additional foreign ob-
jects while working and remove these
promptly.
For operation in enclosed areas, ensure
that a safety distance is kept from edges

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 en-
gine off quickly and safely in an emer-
gency!
Ensure that all protective devices are
mounted and properly adjusted!
If no add-on device is attached, the PTO
shaft must be switched off and covered
with the protective cap.
Suitable shoes must be worn depending
on the type of groundsurface (vegetation,
humidity ...), so that the operator does not
slip or fall.
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 operator must
maintain the distance from the device
shown by the bars.
Riding on the implement during operation
or in transport is not permitted.
In the event of any clogging to the work
equipment or add-on device, the engine
must be stopped and the work equipment
or add-on device must be cleaned with
appropriate tools. There may be tension
in the drive train as a result of the block-
age, which is why you should resolve the
blockage carefully.
In the event of any damage to the ma-
chine or the add-on device, shut down the
engine immediately and have the dam-
age repaired.
In the event of any malfunctions to the
steering, stop and park the machine im-
mediately. Have the fault resolved with-
out delay.
If there is a risk of skidding down on slop-
ing terrain, then the machine must be
held by an attendant using a bar or a
rope. The attendant must be located
above the machine at a safe distance
from the work equipment.
Work across the slope along contour
lines if possible. If possible, turn the ma-
chine in uphill direction.
Finishing work
Never leave the machine unsupervised
while the engine is running.
Switch the engine off before leaving the
machine. Then close the fuel tap(s) (if
present).
Take care not to park the hot machine in
the blazing sun.
Protect the machine against unauthor-
ized use. In ignition key models, remove
the ignition key; otherwise, remove the
spark plug connector.
Implements
Attach an implement only when engine
and implement drive are switched off.
Prior to attaching and starting the imple-
ment, read and observe the operating in-
structions of the implement.
Use adequate tools and wear gloves to
replace implements and parts thereof.

3 Devices and Operating Elements
The meadow mower agria 5300 is suita-
ble to be used for the maintenance of
green areas and parks as well as in agri-
culture and forestry for grass and
meadow mowing and winter service.
When using the machine on public roads
–and during transport –the national road
traffic regulations of the relevant coun-
try must be complied with (marking, light-
ing, etc.).
The implements approved in the Agria
sales list are available.
Engine
The four-stoke petrol engine is to be
used with standard petrol (see chapter
Startup, page 28).
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 applies for
no-load operation! Over-revving the
engine (letting it roar) can result in im-
mediate 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 cylinder free of
dirt and aspirated plant debris.
Idling
Always ensure that the engine idle speed
is adjusted correctly. With speed regulat-
ing lever at idling, the engine should con-
tinue 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 con-
tactless electronic ignition system. We
recommend that any necessary inspec-
tions are carried out by a skilled person
only.

3 Devices and Operating Elements
20
Meadow mower agria 5300
Speed regulating lever
Use the speed regulating lever (C/9) on the steer-
ing bar to continuously adjust the engine speed
between min = IDLE and max = FULL THROT-
TLE as required.
Safety circuit
The machine is equipped with a safety circuit.
O Stop position: When the safety lever (C/4) is
released, the drives are switched off and the en-
gine continues running.
I operating position: For operation, press down
the safety lever (C/4). This establishes a non-pos-
itive connection between engine and gearbox.
•The safety circuit must be operated in two
steps:
1) Pull the stop pawl upwards (disengage)
2) Press the safety lever down.
When the wheel drive or the mowing
drive is switched on, the wheels or mowing
tools, respectively, start moving immediately
when the safety lever is pressed down. This
must be borne in mind during operation. If
necessary, switch off drives that are not
needed.
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 sit-
uation. It swings automatically to "STOP" position!
