Maintenance and

Repair

The trained mechanics of your agria

workshop carry out expert maintenance

and repair.

You should only carry out major mainte-

nance work and repairs on your own, if

you have the proper tools and know-

ledge of machines and internal combu-

stion 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 for pulling the flywheel.

Recommendations

Fuel

Petrol Engine

This petrol engine runs smoothly on

commercial unleaded regular petrol.

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 residues from depo-

siting in the carburetor, fuel filter, and

tank. Or add a fuel stabilizer.

For further instructions refer to „Engine

Preservation“.

agria Flail mower 4500 Hydro 7

Before starting the engine, read the ope-

rating instructions and note:

Warning

This symbol marks all paragraphs in the-

se operating instructions which affect

your safety. Pass all safety instructions

to other users and operators.

Due Use

The flail mower is constructed solely for

the cutting of grass and similar plants

as well as thin non-wooded scrub to

max. ø3 cm in land & forest manage-

ment, green spaces, and other such are-

as (due use).

Any other type of operation is conside-

red undue. The manufacturer is not lia-

ble for any damage resulting from un-

due use, for which the risk lies with the

user alone.

When the flail mower is used on public

roads, the local national road traffic rules

must be observed, e.g. reflectors, lights.

The flail mower is not intended for use

with a trailer on public roads or as as a

tract

ive machine.

Due use includes compliance with

manufacturer’s instructions on operati-

on, maintenance and repair.

Any unauthorized changes to the tool

carrier render manufacturer liability null

and void.

1. Safety Instructions

General Instructions on

Safety and Accident

Prevention

Basic Rule:

The standard accident prevention regu-

lations must be adhered to, as well as

all other generally accepted rules go-

verning operational safety, occupational

health and road traffic regulations.

For drives on public roads, the latest traf-

fic code applies.

Accordingly, check the tool carrier for

road and operational safety each time

you take up operation.

Only persons familiar with the tool car-

rier and instructed on the hazards of

operation are allowed to use, maintain

and repair the tool carrier.

Young persons of 16 years or younger

may not operate the tool carrier!

Only work in good light and visibility.

Operator’s clothes should fit tightly. Avoid

wearing loosely fitting clothes. Wear

solid shoes.

Note the warning and instruction signs

on the tool carrier for safe operation.

Compliance is for your own safety.

When transporting the tool carrier on

vehicles or trailers outside the area to

be cultivated, the engine must be swit-

ched off and you must wait until the

knives have stopped rotating complete-

ly.

Careful with rotating tools – keep at a

safe distance!

1

8 agria Flail mower 4500 Hydro

Due to its centrifugal mass, the cutter

blade can follow up. During that time,

do not stay too close to the mower hou-

sing. Only when the cutter blade is com-

pletely standing still and the spark plug

connector has been withdrawn, works

on the flail mower are permitted.

Foreign powered parts shear and

squeeze!

Riding on the machine during operation

is not permitted.

Match operating speed to conditions.

Do not change settings of governor. High

engine speed increases risk of acci-

dents.

Working Area and Danger

Zone

The user is liable to third parties wor-

king within the flail mower’s working ran-

ge.

Staying in the danger zone is not per-

mitted.

If the operator should notice that a per-

son or animal is staying within this area,

the machine must be shut down without

delay and must not be operated again

before the area is free again.

Check the immediate surroundings of

the machine before you start it. Watch

out for children and animals.

Before you start work, clear the area

from any foreign object. During operati-

on, always watch out for further objects

and remove them in time.

For operation in enclosed areas, ensu-

re that a safety distance is kept to enclo-

sures to prevent damage to tools.

Be careful when mowing; ensure that the

cutter blades does not seize obstacles

such as border stones, enclosures, roots

etc.

Operation and

Safety Devices

Before You Start the Engine

Become familiar with the devices and

operating elements and their functions.

Above all, learn how to shut off the en-

gine quickly and safely in an emergen-

cy situation.

Ensure that all protective devices are

mounted and positioned to provide pro-

tection.

Starting the engine

Do not start engine in closed rooms. The

carbon monoxide contained in the ex-

haust fume is extremely toxic when inha-

led!

Before you start the engine set all opera-

ting elements to neutral or idling position.

Be careful upon starting and during

mowing; do not come directly close

to the cutting section with your hands

or feet.

When starting, it is not permitted to bring

the flail mower into an upright position

or to tilt it.

Do not use assist-starting liquids when

using electrical assist-starting devices

(jumper cable). Danger of explosion.

1. Safety Instructions

1

agria Flail mower 4500 Hydro 9

Operation

Never leave the operator’s position whi-

le the flail mower is at work.

The carrying of additional persons is not

allowed.

If clogging occurs in the cutting section,

shut off the engine, withdraw the spark

plug connector and clean the cutting

section with an appropriate tool.

In case of damage to the flail mower,

immediately shut off the engine and

have it repaired.

Should the machine start to vibrate in

an unusually strong manner, an imme-

diate inspection is necessary.

If steering causes problems, immedia-

tely bring the flail mower to a halt and

shut it off. Have the malfunction elimi-

nated without delay.

Driving speed must always be adjusted

to suit the surrounding conditions. When

driving uphill or downhill and driving

across a slope avoid sudden turns.

When driving in curves switch off the

differential lock.

If possible, always work across the slo-

pe.

Pay careful attention to hills, dips and

other unforeseen dangers.

Stop the cutting tools before crossing

surfaces other than grass.

Never operate machines with damaged

or unfitted safety protection gear.

End of Operation

Never leave the flail mower unattended

with the engine running.

Before you leave the flail mower, shut

off the engine, close the fuel cock, en-

gage the parking brakes and secure

against rolling away.

Before you leave the ride-on flail mower

fully lower the cutting tools.

Secure flail mower against unauthorized

use, remove the ignition key.

Mowing Equipment

In cases of improper operation the sharp

blades of the cutter blades pose a consi-

derable danger of injury. Wear protecti-

ve gloves when working on the cutter

blades.

When changing the cutter blades ensu-

re that the screwing movement leads

away from the blade edges.

Protective glasses and protective gloves

must be worn when sharpening the cut-

ter blades.

Maintenance

Never carry out any maintenance or cle-

aning with the engine running.

After switching off the drive, the flail

mower may continue to coast due to its

centrifugal mass. Do not go too near to

the flail mower during this time. Only

when it has come to a complete stand-

still can it be worked upon.

Before you work on the engine, always

remove spark plug connector.

1. Safety Instructions

1

10 agria Flail mower 4500 Hydro

Check regularly and, if necessary, re-

place all protecting devices and tools

subject to wear and tear.

Replace damaged cutting tools.

Observe maintenance intervals of the

cutter blades.

Always wear safety gloves and use pro-

per tools when exchanging the cutter

sections.

Repair work, such as welding, grinding,

drilling etc., is not allowed to be carried

out on load-bearing, safety-critical parts.

Keep flail mower clean to avoid risk of

fire.

Check nuts and bolts regularly for tight

fit and retighten, if necessary.

Ensure that you re-install all safety and

protective devices and adjust them pro-

perly after maintenance and cleaning.

other commercial spare parts must cor-

respond to quality and technical requi-

rements specified by agria.

Storage

It is not allowed to store the flail mower

in rooms with open heating.

Never park the flail mower in closed

rooms with fuel left in tank. Fuel vapours

are hazardous.

Engine, Fuel, and Oil

Never let the engine run in closed rooms.

Extreme danger of intoxication! For the

same reason, also replace damaged

exhaust pipe immediately.

Be careful when handling fuel. Great

danger of fire! Never refill fuel close to

open fire, inflammable sparks or hot

engine parts. Do not refill fuel in closed

rooms. Do not smoke when refilling!

Refill only with the engine shut off and

cooled down.

Do not spill any fuel, use a proper filling

device (e.g. funnel).

In case of fuel-spillage, pull the flail

mower away from the spillage before you

start the engine.

Make sure fuel is of specified quality.

Store fuel in approved cans only.

Liquids leaking under high pressure, e.g.

fuel, can penetrate the skin and cause

severe injuries. Immediately see a doc-

tor.

Store anti-corrosive agents and stabili-

zing liquids out of reach of children. If

sickness and vomiting occur, see a doc-

tor. If fuel has contacted eyes, rinse

them thoroughly, avoid inhaling of va-

pours.

Read and observe enclosed instruc-

tions.

agria Flail mower 4500 Hydro 11

Before you dispose of opened and see-

mingly empty pressurised tins (e.g. of

assist-starting liquids) make sure they

are completely empty. Empty them in

ventilated places safe from spark forma-

tion or flames. If necessary, dispose of

tins in hazardous waste deposits.

Be careful when draining hot oil, dan-

ger of burns.

Make sure oil used is of specified quali-

ty. Storage is in approved cans only.

Dispose of oil, greases, and filters se-

parately and properly.

Tyres and

Tyre Air Pressure

When working on wheels, make sure

tool carrier is parked properly and se-

cured against rolling off.

Any repairs are to be carried out by trai-

ned mechanics only and with the appro-

priate tools.

Regularly check tyre air pressure. Ex-

cessive pressure may cause bursts.

Retighten attachment bolts of drive-

wheels or check tightness when doing

maintenance work.

18 agria Flail mower 4500 Hydro

Due Use

The flail mower agria 4500 Hydro is sui-

ted for use in farming and forestry for

example for grass maintenance, such as

the mowing of grass, meadows and

scrub up to max. ø3 cm.

Engine



The four-stroke petrol engine runs

on commercial unleaded petrol (refer to

fuel recommendations page 6).

During the first 20 operating hours

(break-in period) do not use engine to

maximum power.

Even after break-in period never use

engine at higher speed than necessary

for the work in hand.

I

High engine speed is harm-

ful to any engine and consid-

erably affects its durability. This app-

lies especially for no load operation.

Any overspeed (have the engine roar)

can result in immediate damage.

Ignition System

The petrol engine is equipped with a

contactless ignition system. We recom-

mend to have necessary checkups done

by an expert only.

Cooling System

The cooling system is fan-cooled. The-

refore keep screen at recoil starter and

cooling fins of cylinder clean and free

from sucked-in plant trash.

Idling-speed

Always ensure that idling-speed is ad-

justed correctly. At low speeds and with

the speed control lever set to idle, the

engine is supposed to run smoothly and

without run-out.

Air Filter

The air filter purifies the air intake. A

clogged filter reduces engine output.
