1 INTRODUCTION
The LELY HIBISCUS 735 Vario (fig. 1) is a pull type, double
cam rake for central delivery. The machine has 2 rotors with
11 tine arms, each equipped with 4 double tines.
The tines give a clean sweep and move the grass to the centre
in an airy windrow.
The HIBISCUS cam rake is mounted to the tractor’s three
point hitch and is driven by the tractor PTO.
The automatically/mechanically steered rear wheel kit en-
sures easy manoeuvring of the machine during operations and
transport with the machine following the tractor line. This
allows for the HIBISCUS rake to continue raking operations
even when turns are made.
Two tandem axles comprising 4 tyres ensure an excellent
raking operation of the HIBISCUS rake also when working in
undulating fields.
2 MOUNTING BEHIND THE TRACTOR
- Mount the drawbar to the machine in such a position that
the horizontal distance of its point of rotation in respect of
the drive shaft is approximately equal to the distance of the
catch hooks of the tractor in respect of the tractor PTO
(fig. 2).
- Adjust the tractor’s three point hitch lower arms at equal
height.
- Fit the lower arms to the linkage pins of the bar.
- Lift the drawbar slightly so that the parking jack is just
clear of the ground. Maintain this height adjustment of the
tractor lift during operations and transport.
- Place the parking jack in the raised position.
- Secure the tractor’s lower arms by means of stabilisation
chains or rods eliminating any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Mount the PTO shaft to the tractor PTO.
At first assembly, or use of another tractor: check the
minimum and maximum overlap of the shaft halves
(Consult the instruction supplied with the PTO shaft.)
- Fit the safety chain of the protection tube to a rigid part of
the tractor.

- Connect the thick hydraulic hose for control of the lift rams
of the rotors to a single acting hydraulic tractor valve with
floating position.
Max. allowed oil pressure: 17,5 MPa (175 bar).
- Connect the hydraulic hoses for control of the slide ram for
width adjustment to a double acting hydraulic valve.
Max. allowed oil pressure: 17,5 MPa (175 bar).
- Put the plug of the lightning cable into the 7-pole tractor
socket and and check the lighting.
3 TRANSPORT
After the machine has been adjusted to the transport position,
it can be transported by the tractor. Transport width amounts
to 2,65 m.
- Use all such lighting and warning signals as are mandatory
by law.
- 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
exceeded.
- To obtain a reduced transport height (3,30 m instead of
3,90 m) 6 tine arms can be dismounted from each rotor and
these can be stored in the support at the rear of the
machine.
After this, the protection bracket can be folded.
- Adjust the machine to the transport position as follows:
• Adjust the machine to the largest working position by
fully extending the slide ram (fig. 3: A).
• Fold the machine up by actuating the lift rams of the
rotors (B).
• Secure the rotors against coming down by fully retrac-
ting the slide ram (C) which activates the machine’s
locking system. At the same time this ensures a low
transport height.
• Make sure that the machine is locked (D).
The machine is now ready for transport.
During transport you should take into account that the rear
wheels are steered. As a result, the machine will behave
slightly different than the usual pull-type machine.
Limit your speed when taking turns. Due to the relatively
high centre of gravity, there is a risk that the machine will tip
over at high speeds.

4 MACHINE ADJUSTMENTS
4.1Conversion to the working position
Make sure that nobody is near the machine when it is
converted from the transport- to the working position.
- Proceed as follows to obtain the working position of the
machine:
• Actuate the lift rams of the rotors thus removing the
pressure from the locking system.
• Unlock the rotors by fully extending the slide ram (fig.
4:A).
• Unfold the rotors by lowering their lift rams (B).
• Adjust the machine to the required working width by
retracting the slide ram (C).
- If necessary: fit the tine arms that were removed for
transport back to the rotors and fold the protection bracket
in the outer position.
4.2Working height adjustment
- Adjust the rotor in a horizontal or slightly inclined
(forward) position by means of the top link.
- Adjust the correct height by means of the spindle. (fig. 5).
The tines should only just touch the ground.
Control of the spindle is easier while the machine is
slightly lifted.
If the required height cannot be obtained with the help of the
spindle adjustment, try this by adjusting the wheels to any of
the 4 possible positions.
- Set the correct working height by placing the wheels in the
correct position (fig. 5:A).
The end part should be secured with at least 6 hexagonal head
screws to ensure a solid connection.

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.
5.1General directions
- Engage the PTO at the lowest possible r.p.m. rate.
- Increase the motor speed.
- Drive forward.
Never drive through a crop when the rotors are not rotating,
since this may cause damage to the tines and tine arms.
Prior to turning on headlands, the rotors can be slightly lifted
so that the tines are clear of the ground.
To achieve this: actuate the lift ram of the rotors.
The machine can be used for making swaths (fig. 6) and for
moving windrows across(fig. 7).

5.2Forward 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
The machine can be dismounted from the tractor both in the
working- and in the transport position.
- Set the parking jack in the bottom position.
- Lower the hydraulic lift until the parking jack rests on the
ground.
- Switch off the tractor engine.
- Disconnect the PTO shaft from the tractor PTO.
- Place the PTO shaft in the hook.
- Depressurize the hydraulic system and disconnect the
hydraulic hoses. Place the insert nipples in the holder (fig.
8).
- Remove the plug for lighting from the socket in the tractor.
- Uncouple the lower arms from the machine.

7 MAINTENANCE
Correct machine servicing is necessary with a view to
reliable and safe working.
7.1Maintenance after operations
- Clean the machine thoroughly.
- Check the tines and tine arms for tightness and damage, 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.
7.2Lubrication
- PTO shaft to be greased every 8 working hours at the grease
nipples on the cross assemblies, protection tubes and
clutch (fig. 9).
- Profiled tubes of the PTO shaft to be greased every 8
working hours.
- Gears in the gearbox over the rotor to be greased every 8
working hours (fig. 10: A). When greasing, keep turning
the rotor bit by bit ensuring effective distribution of grease
all over the gears.
- Grease the pivot points (B) of the wheel assembly every 40
working hours.

7.4Change of oil/grease
- Change the oil of the gearbox (fig. 14) of a new machine (or
after assembly of a new gearbox) after approx. 20 working
hours for the first time. After this, oil has to be changed
after every 400 working hours. For this purpose, you need
to fold the machine down.
(Contents 0,5 litres of transmission-oil; GX 85W140)
The oil of the rotor housing of a new machine (or of a newly
assembled rotor housing) should be changed after approx. 20
working hours. After this replenishment, oil should be
changed every 400 working hours.
Oil has to be changed more often if the machine is operated
under demanding circumstances.
- Fold the machine down.
- Place a receiving container under the rotor housing.
- Unscrew the drain plug from the rotor housing (fig. 15) and
let the oil flow into the container.
- Fill the rotor housing with 6,0 litres of oil which meets the
specification: GX 85W140. For replenish / changing oil,
use only oil which meets this specification.
The correct oil level is just up to the brim of the hole for the
control plug.

7.5Forward / backward inclination of
the rotors
In some cases it is recommended to adjust the rotors in a
slightly inclined forward or backward position, for example,
in case there are differences between the LH and RH rotor.
This can be done as follows:
- Untighten the locking bolts of the adjusting ring (fig. 16,
A).
- Turn the adjusting ring B. Due to the eccentric axle the
rotor will be slightly adjusted.
- Secure the adjusting ring again by fitting the locking bolts
A.
For an even better result, the adjusting ring on the other side
of the support beam could be adjusted as well.
7.6Adjustment of track following
Operation of the machine may lead to deviations in the track
following system of the machine.
These deviations can be adjusted as follows:
- Remove the expansion pin A (fig. 17) from pin B.
- Untighten the securing nut C.
- Slide the ball joint D from pin B.
- Turn the ball jointDafewtimes to correct the deviation.
- Secure the ball joint D by means of the securing nut C.
- Slide the ball joint D onto pin B again.
- Place expansion pin A onto pin B again with the help of a
hammer.
