Safety
This symbol appears in the instruction manual each time there is a safety warning
concerning your safety, the safety of others or functionality of the machine. All
safety instructions must be observed and made available to all users of the ma-
chine.
General
•Ensure you are familiar with all aspects of the machine before use
•There are safety stickers on the machine containing important instructions for
the safety of yourself and others, and correct use of the machine.
•Do not carry passengers during operation or transport.
•Ensure there are no personnel within the machine's working radius before oper-
ating. Operate machine only from inside the tractor.
•When the machine is in its transport position, check that wheel frame cock is
closed.
•Before leaving the tractor or making adjustments, performing maintenance or
repairs on the machine, fully lower to ground, or maintain in transport position,
apply tractor handbrake, switch engine off and remove ignition key to secure
the machine against accidental operation.
•Remember to secure support leg and lift arm (if relevant) with split rings.
•Never leave driver's seat whilst machine is moving.
•Always adapt speed to conditions.
•Do not use machine unless all safety devices are in place. Defective safety de-
vices must be replaced immediately.

GREENLINE
Side 8
Hydraulics
•Lower machine fully for any repair work on the hydraulic system. Relieve hy-
draulic pressure, switch engine off and remove ignition key.
•Clean hydraulic connections thoroughly before reconnecting. When connecting
hydraulic hoses to tractor hydraulics, ensure they are not under pressure.
•It can be difficult to completely depressurise hydraulic systems with pilot-
controlled non-return valves. Hold a cloth around the fittings/part to be removed
to catch any oil.
•Bleed the hydraulic system thoroughly after any repairs.
•Check hydraulic hoses regularly for defects such as cracks, splits, crimps, wear
or breaks. Defective hoses must be replaced immediately.
•Avoid spilling oil on the ground. If oil is spilt, collect and deliver to a destruction
point.
•Clean hands thoroughly after contact with oil and grease. Change oil-stained
clothing immediately. Hydraulic oil can be harmful to the skin.
•Hydraulic oil released under high pressure can penetrate the skin and cause se-
vere injury. In the event of injury, seek medical help immediately.
Assembly
•Danger of crushing! Ensure no personnel are between implement and tractor,
or between the parts to be connected.
Maintenance and repair
•Ensure machine is adequately supported for all repair and maintenance work.
Ensure tractor and machine are properly braked, engine stopped and ignition
key removed.
•Tighten all screw connections after a few hours use. Check all screw connec-
tions regularly and tighten as required. Check all split pins and bolts to avoid
mechanical failure.
•Dispose of oil, grease and filters in accordance with local environmental protec-
tion rules.

GREENLINE
Side 9
Road transport
•All safety and warning precautions mandatory by law must be fitted and tested
before transporting the machine on public roads. The driver is responsible for
correct lighting and warning signs in accordance with traffic regulations.
•Check with local traffic authorities whether transport on public roads is allowed
given the machine's dimensions.
•When transporting, ensure permitted total weight for tractor is not exceeded
and that loading on tractor front axle is not less than 20% of tractor net weight. If
this is the case, use weights on tractor front.
Correct use
•Correct use of the machine includes observing the manufacturer's operating,
maintenance and repair instructions, and that original spare parts are always
used.
•GREENLINE may only be used, maintained or repaired by personnel familiar with
it and who are aware of the risks that can be involved.
•The manufacturer cannot be held liable for injury or damage arising from modifi-
cations made to the machine performed without prior permission from the
manufacturer. Neither can the manufacturer be held liable for injury or damage
arising from incorrect use. Such liability rests solely with the user.
•Do not add extra weight to the machine.

Uses
GREENLINE is a simple, strong roller, designed particularly for rolling and care of
grassed areas.
Fig. 1
GREENLINE is a single-jointed
roller, to which integrated equip-
ment such as: hydraulic harrow,
levelling bar and grass sowing
system can be added.
GREENLINE 300
GREENLINE can be fitted with accessories such as hydraulic harrow and for the care
or sowing of grass.
The levelling bar's main purpose is to level molehills and the like. The harrow aerates
the soil by removing old grass from the roots. It can also be used for levelling mole-
hills or to prepare soil for sowing grass.

Connecting and disconnecting
Connecting
Fig. 2
Connect roller to the tractor's fixed
towbar, where drawbar (A) must fit
between the towbar forks.
Insert pin and raise leg. Remove and
insert leg in transport socket.(B)

•Remember to secure towbar pin with split pin or the like.
•Remember to raise leg and insert in transport socket.

•If tractor towbar is too short, its lift arms can collide with the roller's support
leg if cornering sharply to the left. Avoid by extending tractor towbar.
Hydraulics
GREENLINE requires a double acting hydraulic coupling as standard. The hydraulic
hoses from the coupling go to the wheel frame.

Setting up
The roller is supplied with factory settings, but fine adjustment will always be re-
quired before use. Numerous adjustment options make the roller more flexible and
ensure maximum use.
Adjusting drawbar height
To achieve uniform rolling, the bar (A, Fig. 3) on the mid-section must be parallel
with the ground and the drawbar (B, Fig. 3) correctly positioned in relation to the
tractor. The optimum position can be achieved by adjustment. (NB: See arrow on fig.
3 approx. 50cm)
Fig. 3
Adjustable drawbar
Incorrect drawbar height will cause uneven operation, as the roller will tilt forward
digging the front row of the harrow into the ground.
Fig. 4
To achieve the correct drawbar
height, the drawbar eye can be ad-
justed relative to tractor towbar
height.
Rest machine on support leg. Slacken
bolts (A) and adjust/reverse drawbar.

Filling water
Fig. 5
Turn roller until plug is at top.
Turn roller until plug is at an angle rela-
tive to the ground to achieve desired
level of water if a full roller is not re-
quired.

Drain water before winter if no antifreeze is added.
Draining water
There are plugs for filling/draining at each end of the roller. Turn roller until plug is at
bottom. Remove plugs using a 17 mm Allen key. (Special key included, Item no.
37716)

Water will drain faster if plug in opposite end is removed.

Operation
Correct operation is vital for optimum use of the roller. This applies to working in the
field and for safety. Always ensure you are fully familiar with all safety aspects of
the machine.
Operating position
Tractor must be parked when preparing operating position.

Before raising wheels, check that *harrow is raised to top position to avid damaging
tines and digging into ground.

(fig. 10 pos. A) If *harrow (accessory) is fitted, ensure it is in top position. Also re-
member to lock handle on harrow cylinder.
Operating speed
An operating speed of 6-10 km/h is recommended, but always operate according to
conditions.
Power
Power requirement will depend on soil type, terrain and speed.

Levelling bar
The advantage of the levelling bar is that it is mounted directly on the harrow sec-
tion, allowing it to follow the ground contours. The CB tines are pretensioned to pre-
vent vibration during operation. When used over black soil, the bar will plane the sur-
face to a perfect flat sowing bed.

Harrow depth is hydraulically adjusta-

adjusted manually on the handle (A).
The angle set will be retained regard-
less of depth, as the tines are mounted
in a parallelogram. The harrow section
is supported by the wheel (B), which
maintains a constant depth.
•The harrow section and main frame should be horizontal.

Harrow section hydraulics must be in flow position when tines are in the soil.
Basic setting.
Harrow angle plays a major role in performance. Correct adjustment means the tines
will work at the same depth.
Operation
Adjust harrow depth as required. Adjust depth using the green hose (see "Hose
markings") and the wheel
Retrofitting
The harrow can be factory-fitted, or supplied at a later date if required. A crane or
other lifting device will be required for retrofitting.
Bleed hydraulic system thoroughly to avoid injury to personnel. Move depth-
adjustment cylinders up and down fully several times to bleed system.
