1 INTRODUCTION
The LELY HIBISCUS 425, 455 and 485 S (fig. 1) are trailed, single-rotor
rakes for side delivery. The rake is equipped with 1 rotor with 11 or
13 tine arms, each equipped with 4 double tines.
The tines provide a clean sweep and move the grass to the left side
in an airy windrows.
The HIBISCUS rake is equipped with a steering device and therefore
behaves like a trailed machine. It can continue raking in bends
without any problem.
The tandem-axle wheel assembly ensures excellent raking when
working in undulating fields as well.
2 LINKAGE TO THE TRACTOR
Link the machine to the tractor as follows:
- Adjust the tractor’s three-point-hitch arms at an equal height.
- Fit the lower arms to the linkage pins (cat. II) of the three-point
hitch.
- Attach the top link of the tractor to the machine with a category
II top link pin.
- Place the parking jack in the highest position (fig. 2).
- Secure the tractor’s lower arms with stabilisation chains or rods to
eliminate any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO.
During first assembly or when using another tractor, check
the minimum and maximum overlap of the PTO shaft halves
in all positions
*
.
- Fit the safety chain of the protection tube to a rigid part of
the tractor.
If the machine is equipped with a lighting kit (accessory):
- Insert the plug of the lighting cable into the tractor socket
and check if the lighting is operating correctly.
*. Consult the instructions supplied with the PTO shaft

3 TRANSPORT
The HIBISCUS rake can be transported by the tractor after it has been
adjusted to the transport position.
Adjust the machine to the transport position as follows:
- Slide the swath curtain inwards and secure it with the locking pin.
- Remove the locking bar and fold the safety guard upwards (fig. 3).
Allow the locking bar to slide back into the locking system and
check whether it is properly locked.
Perform this operation on both sides of the machine.
The folded-up safety guards also ensure that the rotor is blocked.
- Remove the tine arms from the rotor and stow them in the holder
at the front of the machine (fig. 4).
During lifting, the machine automatically swings to the
central position. Ensure that no-one is in the vicinity of the
machine and watch out for any obstacles.
- Lift the machine off the ground.
- Secure the steering device by placing the locking pin in the lowest
position (fig. 5).
- Use all lighting and warning signals required by law (or
other regulations prescribed by the authorities).
- For transport on public roads, ensure that the front axle
weight is sufficient (fit front weights, if necessary) and
that the permitted maximum rear axle weight is not
exceeded.
The machine is now ready for transport.
Never allow the PTO shaft to rotate when the machine is in
the transport position.

4 MACHINE ADJUSTMENTS
Put the machine into the working position as follows:
- Place the tine arms on the rotor (fig. 6).
- Remove the locking bar and fold the safety guards downwards.
Allow the locking bar to slide back into the locking system and
check whether it is properly locked.
Perform this operation on both sides of the machine.
- Unlock the steering device by placing the locking pin in the
highest position (fig. 5).
4.1 Swath width
- Slide the swath curtain outwards and secure it with the locking pin
(fig. 7).
The adjustment depends on the amount of crop and the adjusted
working width.
Select a position that allows the crop to flow through between the
rotor and the swath curtain properly and prevents the formation
of heaps.
4.2 Working height
- Adjust the rotor in a horizontal or slightly oblique forward
position using the top link.
If the required height cannot be obtained with the help of the wind
handle, the tandem wheels can be adjusted to 4 height positions.
- Adjust the working height approximatively by positioning the
wheels (A, fig. 8).
The end piece can also be fitted upside down so that the
adjustment is halved. As a result, the rotors on the left side of the
swath can be adjusted a half-position lower, which allows a
greater crop volume to be handled.
Fit the bolts spaced as widely apart as possible in order to achieve
a reliable connection.
- Adjust the correct height using wind handle B. The tines should
only just touch the ground.
The wind handle is easier to operate when the rotors are lifted
slightly.

4.3 Cam track adjustment
The cam track determines the rise and descent of the tines fitted to
the tine arms. Rise and descent moments can be changed by
adjusting this system.
Correct adjustment depends upon crop/terrain conditions and
forward speed. The cam track can be adjusted by placing the
adjustment strip (fig. 9) in one of the holes.
5 OPERATING THE HIBISCUS
• Ensure no-one is near the machine at the moment the
PTO is engaged.
• Do not allow anyone to come within a 25-m radius of the
machine while it is operational.
• Stop the tractor engine before leaving the tractor cab.
• The safety guard and the swath curtain are essential
protective components of the machine. Consequently,
only operate the rake if these components have been
duly fitted.
5.1 General instructions
When turning on headlands, lift the rotors using the tractor
hydraulics.
- Lift the machine.
- Engage the PTO at the lowest possible engine r.p.m.
- Increase the engine speed.
- Drive forward.
Never drive the machine through the crop while the rotor is on the
ground and not rotating. This may damage the tines and tine
arms.
- Lower the machine into the crop.
The machine can be used for making swaths (fig. 10) and moving
swaths (fig. 11).

innovators in agriculture
EN-12
Smaller night swaths can be created by not using the full working
width (fig. 12).
If fuller swaths are required, double (fig. 13) or multiple swaths
(fig. 14) can be created.
121314
innovators in agriculture
EN-13
If crop remains in the middle behind the machine (fig. 15), the top
link must be shortened until the crop is picked up properly.
If the crop is not picked up properly on the sides (fig. 16), the top link
must be extended and the height adjustment or cam track must be
corrected.
Thanks to the steering device, it is possible to make turns with the
HIBISCUS rake that are nearly as just as sharp as those made with a
trailed machine.
- If the machine is lifted in a bend, it will swing to the central
position automatically.
- Ensure that no-one is near the machine and that no
obstacles can be hit.
5.2 Forward speed and PTO speed
Select a forward speed and PTO output (450-500 r.p.m., max.
540 r.p.m.) that ensures a good clean swath.
If the rotor speed is too high, the tines may release the crop too late.
As a result, lumps of material will be scattered behind the machine.
If this occurs, reduce the PTO speed.
Lower the forward speed when the clutch is engaged due to
overload.

6 DISMOUNTING FROM THE TRACTOR
Always place the machine on hard, even ground.
- Secure the steering device with the locking pin (fig. 17).
- Place the parking jack in the bottom position.
- Lower the tractor hydraulics until the parking jack rests on the
ground.
- Switch off the tractor engine.
- Disengage the PTO shaft from the tractor PTO.
- Place the PTO shaft in the hook (fig. 18).
If the machine is equipped with a lighting kit:
- Remove the lighting plug from the tractor socket.
- Disconnect the top link from the machine.
- Disconnect the lower arms from the machine.

7 MAINTENANCE
• Correct machine servicing is vital for ensuring reliable
and safe operation.
7.1 Maintenance after operation
- Clean the machine thoroughly.
- Check the tines and tine arms for tightness or any damage.
- Grease the machine with an anti-corrosion agent.
Pay special attention to the tines. Smooth tines without any rust
stimulate an unhampered crop flow.
7.2 Lubrication
All lubrication points of the machine can be greased with a
biodegradable grease (Total Biomultis SEP2), unless stated
otherwise.
- PTO shafts must be greased every 8 working hours via the grease
nipples on the cross assemblies, protection tubes and slip clutch
(fig. 19).
- Grease the profiled tubes of the PTO shaft every 8 working hours
(fig. 19).
- Grease the gears in the gearbox over the rotor every 8 working
hours (A, fig. 20). While greasing, keep turning the rotor bit by bit
to ensure the grease is distributed effectively all over the gears.
- Grease the bearing block B of the PTO extension every 8 working
hours.

7.3 Periodic maintenance
Periodic maintenance must be carried out:
• at the start of the raking season;
• before prolonged storage of the machine;
• when the machine is used extensively during the season.
- Grease all points of the machine listed in § 7.2 “Lubrication”.
- Grease the spring-loaded locking pins of the yoke lock of the PTO
shaft.
- Check if the PTO shaft telescopes smoothly.
A damaged PTO shaft may cause excessive wear and tear to the
machine and tractor.
- Grease the cam track in the rotor every 1,000 hectares or once a
year with a high-quality grease (Molykote BR2Plus).
The cam track can be accessed easily by removing one or more tine
arm shafts from the rotor.
- Check whether the small roller is in the cam track when attaching
the tine arm shaft. It is if the rotor can be fully rotated by hand.
- Check the machine for any damage and defects. Repair or replace
damaged parts.
- Check the tyre pressure (fig. 23).
- Check all bolts and nuts for tightness.
Pay particular attention to the bolts that secure the segments in
the rotors (fig. 24).
Tighten loose bolts/nuts to the torques specified below.

A OPTIONAL EXTRAS
Tine retainer
The tine arms of the HIBISCUS rake can be equipped with a tine
retainer. This simply accessory ensures that in the event of a collision
with an obstacle, the tines will not fall off the tine arms due to
broken coils and remain behind on the field.
Lost tines can cause considerable damage to a baler, loader wagon
or harvester.
Cam track lubrication
The cam track in the rotor of the HIBISCUS rake is lubricated with
grease. The machine has a tine arm shaft equipped with a grease
nipple, which simplifies and speeds up the cam track lubrication
procedure. This grease nipple ends up in the cam track, which
ensures that the grease reaches the appropriate area.
Spare wheel support
The HIBISCUS rake can be equipped with a spare wheel support.
Carrying a spare wheel allows any punctures that occur in the field
to be repaired quickly.
Gauge wheel
Equipping the HIBISCUS rake with a gauge wheel improves the
rakesabilitytofollowgroundcontours.Thismayberequiredonhillyterra

'The top link is replaced with a chain, and the gauge wheel assumes
the leveling function of the top link. As a result, the machine
