1 INTRODUCTION
The LELY HIBISCUS 425, 455 and 485 (fig. 1) are hitch carried,
single rotor rakes for side delivery. The machine has 1 rotor with
either 11 or 13 tine arms, each equipped with 4 double tines.
The tines give a clean sweep and move the grass to left hand side in
an airy windrow.
As standard the HIBISCUS rake comes with a pivoting 3 point
linkage headstock giving the machine trailing characteristics. This
allows for the machine to continue raking operations even when
turns are made.
The tandem axle wheel assembly ensures an excellent raking
operation of this rake also when working in undulating fields.
2 LINKAGE TO THE TRACTOR
- Adjust the tractor’s three point hitch lower arms at equal height.
- Fit the lower arms to the linkage pins (cat. II) of the machine’s
headstock.
- Fit the tractor top link to the machine by means of a category II
top link pin.
- Place the parking jack in the raised position (fig. 2).
- Secure the tractor’s lower arms by means of stabilisation chains
or rods eliminating any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO.
At first assembly or use of another tractor: check the minimum
and maximum overlap of the PTO shaft halves*.
- Fit the safety chain of the protection tube to a rigid part of the
tractor.
If the machine is fitted with a lighting kit (option):
- Put the plug of the lighting cable in the tracor socket and
check the lighting for correct operation.
*. Consult the instruction supplied with the PTO shaft

3 TRANSPORT
After the machine has been adjusted to the transport position, it can
be transported by the tractor.
Put the machine into the transport position as follows:
- Slide the swath curtain inwards and lock it by means of the
locking pin.
- Pull out the locking bar and fold up the protection guard (fig. 3).
Then slide the locking bar back into the locked position and check
that it is properly secured.
This check is to be carried out on either side of the machine.
In raised position, the safety guards also ensure that the rotor is
blocked.
- Remove the tine arms from the rotor and place them in the holder
at the front of the machine (fig. 4).
During lifting the machine automatically swivels into the central
position. Make sure that nobody is near the machine and pay
attention to obstacles, if any.
- Lift the machine from the ground.
- Lock the trail device by placing the locking pin in the lowermost
position (fig. 5).
- Use all such lighting and warning signals as are mandatory by
law (or other regulations prescribed by the authorities).
- For transport on public roads: make sure that the front axle
weight is sufficient (fit front weights, if necessary) and that the
rear axle weight allowed as a maximum is not needed.
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:
- Slide the tine arms onto the rotor (fig. 6).
- Pull out the locking bar and fold down the protection guard. Then
slide the bar back into the locked position and check that it is
properly secured.
This check is to be carried out on either side of the machine.
- Unlock the trail device by placing the locking pin (fig. 5) in the
top position.
4.1 Swath width
- Slide the swath curtain outwards and lock it by means of the
locking pin (fig. 7).
Adjustment is dependent upon crop quantity and desired working
width.
Select a position in which there is a smooth flow of crop material
between the rotor and the swath curtain without build-up of
material.
4.2 Working height
- Adjust the rotor in a horizontal or slightly inclined (forward)
position by means of the top link.
If the required height cannot be obtained with the help of the spindle
adjustment, try this by adjusting the tandem wheels to any of the 4
possible positions.
- Adjust the working height roughly by positioning the wheels (A,
fig. 8).
The end piece can also be fitted upside down, which reduces the
adjustment to half. This makes it possible to adjust the rotor at the
swath side (LH) a half-position lower, so that a larger crop
volume can be handled.
Fit the bolts spaced as widely apart as possible to achieve a
reliable connection.
- Adjust the exact height by means of the spindle B. The tines
should only just touch the ground.
Control of the spindle is easier while the machine is slightly lifted.

4.3 Cam track adjustment
Rising and descending of the tines that are fitted on the tine arms is
ensured by the cam track. By adjusting this system, rise and descent
moments can be changed.
Correct adjustment depends upon crop/terrain conditions and
forward speed. The cam track can be changed by placing the
adjustment strip (fig. 9) in one of the holes.
5 OPERATING THE HIBISCUS®
• Make sure that nobody is near the machine at the moment
the PTO is engaged.
• Do not allow anyone to come within a 25 m radius from the
machine during work.
• Stop the tractor engine before leaving the tractor cab.
• The safety guards and the swath curtain are essential
protective components of the machine. So: operate the rake
only with these components duly fitted.
5.1 General directions
For making turns on headlands, the machine can be lifted by means
of the tractor’s hydraulic lift.
- Raise the machine.
- Engage the PTO at the lowest possible engine r.p.m..
- Increase the motor speed.
- Drive forward.
Never drive the machine through the crop while the rotor is on the
ground without rotating. This may cause damage to the tines and
tine arms.
- Lower the machine into the crop.
The machine can be used for making swaths (fig. 10) and for moving
windrows across (fig. 11).

EN-12
By using only part of the full working width, smaller night swaths
can be made (fig. 12).
If fuller windrows are required, double swaths (fig. 13) or multiple
swaths (fig. 14) can be made.

13
14

EN-13
If some crop is left in the middle behind the machine (fig. 15), the
top link should be turned in until the crop material is taken up
effectively.
In case the crop is not effectively taken up on the sides (fig. 16), the
top link has to be turned out whilst -if need be- the height adjustment
or cam track should be corrected.
Because of the trail device, turns made with the HIBISCUS rake are
almost as short as those made by a trailed machine.
- If the machine is lifted in a turn it will automatically swivel
into the central position.
- Make sure that nobody is near the machine and that obstacles
cannot 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.) which ensures a good and clean windrow.
If the rotor speed is too high there is the risk of crop not being
released soon enough by the tines so that lumps of material are
scattered behind the machine. If so, reduce the PTO speed.
Lower the forward speed when the clutch is engaged as a result of
overload.

6 DISMOUNTING FROM THE TRACTOR
Always place the machine on hard, even ground.
- Lock the trail device by means of 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 fitted with a lighting kit:
- Remove the plug for lightning from the tractor socket.
- Disengage the top link from the machine.
- Disconnect the lower arms from the machine.

7 MAINTENANCE
• Correct machine servicing is necessary with a view to
reliable and safe working.
7.1 Maintenance after operations
- Clean the machine thoroughly.
- Check the tines and tine arms for tightness and damages, if any.
- Grease the machine with a rust preventive.
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 to be greased every 8 working hours by the grease
nipples on the cross assemblies, protection tubes and slip clutch
(fig. 19).
- Profiled tubes of the PTO shaft to be greased every 8 working
hours (fig. 19).
- Gears in the gearbox over the rotor to be greased every 8 working
hours (A, fig. 20). When greasing, keep turning the rotor bit by
bit, ensuring effective distribution of grease all over the gears.
