Recommendations
Lubricants and
Anti-Corrosive Agents:
Use the lubricants specified for engine
and gearbox (see “Specifications”).
We recommend using Bio-lubricating
oil or Bio-lubricating grease for “open”
lubrication points or nipples (as specified in the operating instructions).
We recommend using Bio-slushing oil
to preserve machines and attachments
(do not apply on painted covers). You
can brush or spray the oil.
Anti-corrosive agents are environmentally friendly and degrade fast.
Using ecologically safe Bio-lubricants
and Bio-anti-corrosives, you contribute
to environmental protection and to the
wellbeing of humans, animals and
plants.
Fuel
This engine runs smoothly on commercial unleaded regular and supergrade
petrol (including E10).
6
Do not add oil to petrol.
If, for environmental reasons, you use
unleaded petrol, make sure the fuel is
drained completely when shutting down
the engine for more than 30 days. This
is to prevent resin residue from depositing in the carburetor, fuel filter, and
tank. Or add a fuel stabilizer to the fuel.
For further instructions refer to “Engine
Preservation”.
Maintenance and Repair:
The trained mechanics of your agria
workshop expertly carry out any maintenance and repair work.
You should only carry out major maintenance work and repairs on your own,
if you have the proper tools and knowledge of machines and internal combustion engines.
Do not hammer against the flywheel with
a hard object or metal tools as it might
crack and shatter in operation, causing
injuries and damage. Only use suitable
tools to pull off the flywheel.

1. Safety Instructions
Before starting the engine, read the operating instructions and note:
1
Warning
This symbol marks all paragraphs which
affect your safety. Pass all safety instructions to other users and operators.
Due Use
The grassland mower is constructed
solely for the cutting of grass and similar plants as well as thin non-wooded
scrub in land & forest management,
green spaces, and other such areas and
may also be used as a snow-clearing
machine after it has been fitted with a
suitable rake blade (due use).
Any other type of operation is considered undue. The manufacturer is not liable for any damages resulting from
undue use, for which the risk lies with
the user alone.
When the grassland mower is used on
public roads, the local national road traffic rules must be observed, e.g. reflectors, lights.
The grassland mower is not intended for
use with a trailer on public roads or as
as a tractive machine.
General Instructions on
Safety and Accident
Prevention
Basic Rule:
The standard accident prevention regulations must be adhered to, as well as
all other generally accepted rules governing operational safety, occupational
health and road traffic regulations.
For drives on public roads, the national
traffic code applies.
Accordingly, check the grassland mower
for road and operational safety each time
you take up operation.
Only persons familiar with the mower
and instructed on the hazards of operation are allowed to use, maintain and
repair the mower.
Teenagers of 16 years or younger may
not operate the grassland mower!
Only work in good light and visibility.
Operator’s clothes should fit tight. Avoid
wearing loose fitting clothes. Wear solid
shoes.
Note the warning and instruction signs
on the mower for safe operation. Compliance is for your own safety.
Due use includes compliance with
manufacturer’s instructions on operation, maintenance and repair.
When transporting the mower on vehicles or trailers outside the area to be
mowed, ensure that the engine is turned
off.
Any unauthorized changes to the mower
render manufacturer liability null and
void.
Careful with rotating tools – keep at a
safe distance!
8
agria Grassland Mower 5300
1. Safety Instructions
Beware of coasting tools. Before you
start any maintenance or repair on them,
wait until tools have come to a complete
stop.
Foreign powered parts shear and crush!
Riding on the attachment during operation is not permitted.
Implements and their weight affect the
driving, steering, braking, and tip-over
characteristics of the mower. Therefore,
ensure steering and braking functions
are sufficient. Match operating speed to
conditions.
Do not change settings of governor. High
engine speed increases risk of accidents.
Working Area and Danger
Zone
The user is liable to third parties working within the mower’s working range.
Staying in danger zone is not permitted.
Check the immediate surroundings of
the mower before you start it. Watch out
for children and animals.
Before you start work, clear the area
from any foreign object. During operation, always watch out for further objects
and remove them in time.
For operation in enclosed areas, ensure
that a safety distance is kept to enclosures to prevent damage to tools.
Operation and Safety
Devices
1
Before you start the engine
Become familiar with the devices and
operating elements and their functions.
Above all, learn how to turn the engine
off quickly and safely in an emergency.
Ensure that all protective devices are
mounted and positioned to provide protection.
With no implement mounted, make sure
PTO-shaft is covered with the protective cap.
Starting the engine
Do not start engine in closed rooms. The
carbon monoxide contained in the exhaust fume is extremely toxic when inhaled.
Before you start the engine set all operating elements to neutral or idling position.
For starting the engine, do not step in
front of the mower and the implement.

Drive-Wheels
W
Only mount and dismount
drive-wheels with engine
turned off.
The drive-wheels are equipped with a
detent spring (1) and can be mounted
and adjusted without tools.
The detent spring engages into a ring
groove on the wheel-shaft to hold the
drive-wheel.
On both sides of the wheel-shaft there
are 2 ring grooves respectively. With
detent spring engaging into outer ring
groove, the drive-wheel turns in neutral
on wheel-shaft. With detent spring engaging into inner ring groove, the drivewheel engages with a toothed wheel on
the wheel-shaft to be driven by the
same.

4. Commissioning and Operation
Commissioning the Machine
Please note that durability and operational safety of the engine depend to a large
extent on its breaking-in. Always allow a cold engine to warm up for some minutes
and never run it at full throttle at the beginning.
Please note: for the first 20 hours of operation (break-in period) do not use the
engine at full power.
Make sure you check and maintain air filters regularly and use clean fuel.
Only use branded petrol.
Only use fresh, clean fuel (not older than 3 months) and approved fuel cans to be
purchased in special shops. Rusty sheet metal cans or fuel cans not suited for
petrol are not permitted.
For the first commissioning or after longer periods of no operation, fill fuel tank to
maximum to avoid starting problems.
Be careful when dealing with fuel.
Fuel is easily inflammable and explosive in certain conditions!
4
l Do not refill in closed rooms.
l Before each fuel fill, shut off the engine and
wait until it has cooled off.
l Never refill close to open fire, inflammable
sparks or hot engine parts.
l Do not smoke during filling!
l Do not spill any fuel, use a proper filling device.
Do not cause fuel tank to overflow, but leave a 5
mm margin for the fuel to expand.
