The positions left, right, rear and front in this manual refer to either:
•The Hibiscus as seen in the driving direction.
•The particular component, as seen when standing in front of it.
The Lely Hibiscus 655 SD is a pull-type, twin-rotor cam rake for side
delivery. The rake is equipped with 2 rotors with 11 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 swath.
The rotors of the Lely Hibiscus 655 SD rake are fitted to the carriage by
means of a 3-D system, allowing them to follow ground contours
independently of the carriage.
The 4-wheel assembly ensures excellent raking when working in
undulating fields as well.
The transport wheels of the machine are fitted with wheel steering as
standard, which ensures that the machine follows the tractor in the same
tracks.
1.2Intended Use

The Lely Hibiscus 655 SD is designed to be used as a rake pulled and
powered by a tractor.
The rake has been built exclusively for raking grass, hay and straw lying
on the ground of an agricultural field (= proper use). Usage going
beyond that does not constitute proper use. The manufacturer is not
liable for damage resulting from improper use; the operator only bears
the risk.
Intended uses also implies that the instructions and rules prescribed by
the manufacturer are observed.
1.3Foreseeable Misuse
The rake must not be operated when stationary or outside an
agricultural field.

6.5Lift the Rotors to turn on Headlands
Never drive the machine through the crop while the rotors are on the
ground and are not rotating. This may damage the tines and tine arms.
When the Hibiscus is operated in the floating position the oil pressure in
the system is disabled. This makes that the Hibiscus follows the contour
line of the land.
The front rotor is lifted first, followed by the rear rotor. The timing and
speed of lifting and lowering the rotors can be adjusted (see page 7-6).
To enable turning on headlands, the rotors can be lifted (approx. 60 cm
(1.96 ft). When the end of the field is reached, do the following to turn
on the headland:
1.Operate the single-acting valve of the tractor to lift the rotors up
to the headland position.
2.Make the turn with the tractor.
3.Put the single-acting valve of the tractor in the floating position to
lower the rotors into the crop. The rams must telescope smoothly
throughout the operation.
6.6Start raking
4.1064.8502.0 -
Make sure no people are near the Hibiscus at the moment the PTO
is engaged.
Keep safe distance from people. If a person comes near the
Hibiscus, stop the tractor and disengage the PTO.
Switch off the tractor engine and remove the key before leaving
the tractor cab.
The safety guards and the swath curtain are essential protective
components of the machine. Consequently, only operate the rake
if these components have been duly fitted.
Make sure that the headstock of the Hibiscus is connected to the
tractor when you connect the hydraulic hoses and/or operate the
hydraulic systems of the Hibiscus.
Do not drive the machine through the crop when the rotor is on the
ground and not rotating. This causes damage to the tines and the tine
arms.
OPERATING INSTRUCTIONS6-9
Page 38
Preparation
Make sure the Hibiscus is properly adjusted before raking.
If necessary:
•Adjust the swath width (see page 7-1).
•Adjust the working height (see page 7-2).
•Adjust the cam track (see page 7-5).
•Adjust the lifting and lowering speed (see page 7-6).
Procedure
1.Operate the single-acting valve of the tractor to move the Hibiscus
to the headland position.
2.Carefully engage the PTO at the lowest possible engine speed.
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. Reduce
the PTO speed if this occurs.
3.Slowly increase the speed of the PTO to 450 – 500 rpm (max. 540
rpm).
4.Drive the tractor at a maximum speed of 12.5 km/h (7.8 mph).
5.Put the single acting valve of the tractor in the floating position to
lower the rotors into the crop.
6.If you want to turn on headlands, operate the single-acting valve
of the tractor to move the rotors to the headland position (see
page 6-9).
6.7Stop raking
1.Stop the tractor.
2.Operate the single-acting valve of the tractor to lift the Hibiscus to
the headland position.
3.Disengage the PTO.
4.Wait for all moving parts to stop.
5.When leaving the field:
1.Put the Hibiscus into the transport position (see page 6-4).
2.Make sure the support frames are secured with the locking
hooks (see figure 10 on page 6-6).
6.8Take the Hibiscus out of Operation

7.2Adjust the Working Height
When raking straw, the wheel height must be adjusted higher.
When the tines take up crop within the raking movement, the tines bend
increasingly rearwards as there is more crop in front of them.
Consequently, the tine tips are moved higher from the ground. This can
be compensated by adjusting the rotor height at the side of the swath
board and in the direction of travel. The height adjustment system (see
figure 16 on page 7-3) of the rotor wheels is used for rough height
adjustment. The winding handle (see figure 18 on page 7-5) is used for
fine height adjustment.
1.Take the Hibiscus out of operation (see page 6-10).
2.Turn the winding handle (1) (see figure 18 on page 7-5) to the
middle of the height adjustment range.
3.Examine the height of the tines at the front side of the rotor:
•If the height of the tines is less than 5 cm (2 in) from the
ground no rough height adjustment of the rotor wheels is
necessary. The adjustment system of the rotor wheels must
only be used to adjust the rotor height at the side of the
swath board and in the direction of travel to make the rotor
tilt slightly.
•If the height of the tines is more than 5 cm (2 in) from the
ground the general height of the rotor wheels must be
adjusted roughly with the adjustment system of the rotor
wheels also.
4.Roughly adjust the height of the front rotor wheels. Install the left
front wheel in a higher wheel position than the right front wheel
and / or put more shims in the upper position at the left front
wheel to make the rotor tilt slightly towards the swath board (see
figure 17 on page 7-4).
5.Put the rear wheels of the rotor in a lower wheel position than the
front wheels to make the rotor tilt slightly in the forward direction.
Install the left rear wheel in a higher wheel position than the right
rear wheel and / or put more shims in the upper position at the left
rear wheel to make the rotor tilt slightly towards the swath board
(see figure 17 on page 7-4).
6.Adjust the height of the tines at the front side of the rotor with the
winding handle so that the tines are only slightly above the
ground.

7.3Adjust the Cam Track
The position of the cam track determines when the tine arms release the
crop. Adjustment of the cam track to earlier or later crop release has an
effect on the shape and width of the swath. Optimal adjustment is
related to the crop, its humidity and its volume.
1.Move the Hibiscus to the working position.
2.Take the Hibiscus out of operation (see page 6-10).

The Lely Hibiscus 655 SD rake has two adjustable throttle valves in the
hydraulic system that allow the lifting and lowering speed of the rotors
to be adapted to prevailing conditions.
Throttle vale A (see figure 21 on page 7-7) controls the lifting and
lowering speed of both rotors out of and into the headland position.

9TROUBLESHOOTING
Symptom
The crop is scattered behind the Hibiscus.
The overload clutch of the PTO shaft engages.
The working width or shape of the swath is not
correct.
Not all crop is raked from the field.
One of the tines is broken by an excessive load.
Too much soil is raked with the crop.
4.1064.8502.0 -
The rear rotor lowers too early / late on the
headland.
Action
•Reduce the PTO speed.
•Reduce the drive speed.
•When raking excessive crop volume: do not
use the full width capacity of the Hibiscus.
•Adjust the PTO speed.
•Adjust the driving speed of the tractor.
•Adjust the cam track (see page 7-5).
•Adjust the swath width (see page 7-1).
•Adjust the working height (see page 7-2).
•Adjust the height of the rotor wheel
assembly (see page 7-2).
•Replace the broken tine (see page 8-18).
•Increase the working height (see page 7-2).
•Adjust the driving speed of the tractor.
•Adjust the lowering speed of the rear rotor
(see page 7-6).
Both rotors lower too quick / slow.
The chassis is lifted by the rotor when driving
over the field.
The rear rotor leaves a strip of crop.
Troubleshooting9-1
•Adjust the lowering speed of the rotors
(see page 7-6).
•Adjust the oil flow of the tractor (refer to
the manual of the tractor).
•Put the Hibiscus in the floating position.
•Adjust the PTO speed.
•Adjust the cam track of the front rotor:
later release of crop (see page 7-5).
•Adjust the rotor slightly forward in the
direction of travel (see page 7-2).
Page 74
Symptom
Action
A part of the tine arms rake higher than the other
tine arms.
The rotors do not lift from the headland position
into the transport position.
•Loosen the tine arm carriage bolts of all
tine arms and retighten them according to
the crosswise pattern (see page 8-14).
•There is not enough pressure in the
headland hydraulic circuit to open the
double check valve. Operate the single
acting valve to recharge the pressure.
•The double acting check valve is broken.
Have the check valve replaced by an
authorized technician.
