1 INTRODUCTION

The LELY HIBISCUS 725 and 805 (fig. 1) are pull type, double

cam rakes for central delivery. The machines have 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 working and swathwidth of the machine can be adjusted in two

positions.

The wheel assembly comprising 4 tyres ensures an excellent raking

operation of the rake also when working in undulating fields.

The HIBISCUS 725 cam rake can be supplied in 2 basic models:

725 Classic and 725 Master, the HIBISCUS 805 cam rake is Only

available in the Master model.

The HIBISCUS Classic model comes as standard with oilbath-

lubricated rotors, non-detachable tine arms, fixed protection

brackets as well as a fixed wheel assembly (fig. 2). The wheel

assembles fitted on the HIBISCUS Classic model comprise of

double tyres.

SA - Steering Axle - is available as an option for the HIBISCUS 725

Classic cam rake.

The HIBISCUS Master cam rake is fitted with grease- lubricated

and segmented rotors, detachable tine arms and telescoping

protection brackets to ensure a lower transport and storing height

(fig. 3).

As standard, the Master model is equipped with steering wheel axles

and a tandem wheel assembly. The rotors themselves come with a

cam adjustment facility, which allows adaptation of the lifting and

descending movements of the tines to prevailing circumstances.

2 MOUNTING BEHIND THE TRACTOR

Machines with a draw bar eye are linked to the tractor as follows:

- Adjust the draw bar eye (fig. 4) at the correct height for the tractor

by means of the parking jack.

- Couple the machine to the tractor; use a solid pin and secure it

carefully.

- Turn up the parking jack and place it in the highest position.

Linking of a machine to the tractor three point hitch is carried out as

follows:

- Adjust the tractor’s three point hitch lower arms at equal height.

- Fit the lower arms to the linkage pins (cat II) of the headstock

(fig. 5).

- Lift the drawbar slightly so that the parking jacks are just clear of

the ground. Maintain this height adjustment of the tractor lift

during operations and transport.

- Place the parking jacks 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 PTO halves

- Fit the safety chain of the protection tube to a rigid part of the

tractor.

- Connect the hydraulic hoses to a double acting hydraulic tractor

valve that has a floating position.

Max. allowed oil pressure: 21,0 MPa (210 bar).

- Place the end of the control cord for locking the ram in the tractor

cab.

- 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

E-10

3 TRANSPORT

After the machine has been adjusted to the transport position, it can

be transported by the tractor. Transport width amounts to 2,8 m.

Put the machine into the transport position as follows:

- The HIBISCUS 725 Classic model has a transport height of

3,95 m.

To reduce the transport height of the HIBISCUS Master cam rake

to 3,50 m, the 6 outer tine arms of each rotor can be demounted

and stored in the holder fitted to the back of the machine.

After this procedure, the protection bracket can be telescoped

inwards (fig. 6).

- Pull up the locking hooks for the hydraulic rams and retract the

rams completely.

- Check if the rams are secured by the locking hooks (fig. 7).

- 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.

E-11

4 MACHINE ADJUSTMENTS

Put the machine into the working position as follows:

- Pull up the locking hooks of the hydraulic rams and lower the

machine carefully by means of the rams.

• In case of a double acting valve without floating position:

extend the ram to such an extent that the extremities of the ram

are right in the middle of the slotted holes.

• In case of a double acting valve with floating position: place the

valve in the floating position.

- Fit the outer tine arms.

Slide the protection brackets of the Master model in the extreme

position (fig. 8).

4.1 Working width

The machine’s working width is determined by the position of the

mounting plates for the rotors (fig. 9). These plates are factory-fitted

to the smallest working width.

If the working width or associated swath width does not comply

with your requirements, another position can be set.

This procedure is explained in supplement B.

4.2 Working height

- Adjust the rotor in a horizontal or slightly inclined (forward)

position by means of the three point hitch or the top link A

(fig. 10).

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.

- Adjust the working height roughly by positioning the wheels (B).

The end part should be secured with at least 6 hexagonal head

screws to ensure a solid connection.

- Adjust the correct height by means of the spindl C. The tines

should only just touch the ground.

Control of the spindle is easier while the machine is slightly lifted.

The dual wheel axle of the Classic model offers the possibility to set

the rotors in a horizontal position by moving the rings underneath

the pivot bushings up or down the bushings (D).

B, min. 6!

E-12

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. 11) 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.

5.1 General directions

To enable turning on headlands, the rotors can be lifted

(approx. 25°) so that the rams are stopped by the abutments.

To achieve this: actuate the lift rams of the rotors.

- Lift the rotors up to the headland position.

- Engage the PTO at the lowest possible r.p.m. rate.

- Increase the motor speed.

- Drive forward.

Never drive the machine through the crop while the rotors are on

the ground without rotating, since this may cause damage to the

tines and tine arms.

- Lower the machine into the crop.

- Ensure the floating position of the hydraulic valve; the rams have

to telescope smoothly throughout the operation.

If the tractor spool valve does not have a floating position, keep

the valve in the position for lowering while you are driving, just

as long until the extremities of the ram are right in the centre of

the slotted holes.

The machine can be used for making swaths (fig. 12) and for moving

windrows across (fig. 13).

*. Cam track adjustment is only available on the Master

models of the HIBISCUS cam rakes

E-13

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

The machine can be dismounted from the tractor both in the working

and in the transport position.

- Set the parking jack(s) in the bottom position.

- For the draw bar eye model: extend the parking jack so the draw

bar eye is no longer resting on the draw hook.

Lower the tractor hydraulics until the parking jacks rest on the

ground.

- Switch off the tractor engine.

- Disengage the PTO shaft from the tractor PTO.

- Place the PTO shaft in the hook (fig. 14).

- Depressurize the hydraulic system and disconnect the hydraulic

hoses.

- Place the dust caps on the plugs and hook the plugs to the support

on the drawbar (fig. 14).

- Remove the plug for lightning from the tractor socket.

- For the draw bar eye model: remove the pin from the draw bar

clevis.

Disconnect the lower arms from the machine.

7.4 Change of oil in gearboxes

Change the oil of the gearboxes and the rotor (only HIBISCUS

Classic type) of a new rake (or after assembly of a new gearbox)

after approx. 30 working hours for the first time. After that, oil has

to be changed every 250 working hours.

The Classic model of the HIBISCUS cam rake is fitted with oil-

filled rotors.

The rotors of the Master model come with grease lubrication.

- Place a receiving container underneath the gearbox or rotor.

- Unscrew the drain plug from the gear box or rotor in question and

let the oil flow into the receiving container (arrow, fig. 21).

- Fill the gearbox A (fig. 21) with 1,7 l GX85W-140 transmission

oil.

- Fill the rotors B with 6,0 l GX85W-140 transmission oil.

An incorrect oil quantity may lead to overheating and

unrepairable damage of the gearbox and/or the rotor.

Change the oil more often when operating the machine in

extreme working conditions.

A OPTIONAL EXTRAS

Tine loss protection device

The tine arms of the HIBISCUS rake can be simply fitted with tine

loss protection devices. This simple option prevents tines (after

having hit an obstacle) from getting away from their tine arms due

to a broken coil.

Lost tines that stay behind in the field may cause major damage to a

baler, pick-up loader wagon or harvester.

Portal type headstock

For linkage to the tractor, the HIBISCUS Classic cam rake is

supplied with a drawbar eye, combined with a wide angle PTO

shaft. In stead of this linkage facility, a portal type headstock with a

standard PTO shaft can be supplied, if required.

This makes it easier to use the machine when having to use a tractor

that does not have a link-up hook.

Cam track greasing

The cam track of the Master model is greased; the HIBISCUS 805

Master model is fitted as standard with a grease nipple for the cam

track. As an option, such a grease nipple is also available for the

HIBISCUS 725 Master cam rake.

Spare wheel with support

To enable quick mending of a flat tyre in the field, the HIBISCUS

rake can be fitted with a support for a spare wheel.
