1. INTRODUCTION
The Lely Hibiscus 915 CD Vario is a pull type twin rotor rake to rake grass or
hay.
The Hibiscus has:
•
Two rotors,
• Cam track
• Tandem-axle wheel,
• Steering device
• Hydraulic systems.
• Optional extras (page 1‑3).
The two rotors have 13 tine arms, each with four double tines.The tines
provide a clean sweep and move the grass to the center in a fluffy swath.
The adjustable cam track determines the pick and release moment of the
crop.
A tandem-axle wheel makes sure that quality raking is achieved even in
undulating fields.
The steering device makes the Hibiscus operate as a trailer. The Hibiscus
can continue raking when it goes round bends.
The hydraulic system moves the Hibiscus into the following positions:
• from the transport position to the working position and reverse,
• to the headland position,
• to the working width.

1.1 Optional extras
1.1.1 Tine retainers
Tine retainers can be installed on the tine arms. This makes sure the tines
do not fall off the tine arms after breakage. Lost tines can cause damage to
other machinery.

1.1.2 Independent rotor lift
Always use the independent rotor lift in combination with the transport
wheels 15.0/55-17.
The independent rotor lift system replaces a part of the standard hydraulic
system and is used to lift the rotors independent from each other.

2. SAFETY
This chapter contains safety instructions you must obey when you use or do
maintenance on your Lely Hibiscus. It also explains the safety decals on the
Lely Hibiscus.
2.1 Signal words
Note the use of the signal words DANGER, WARNING and CAUTION. The
signal word for each message uses the following guidelines:
Danger: Indicates an imminently hazardous situation that,
if not avoided, will result in death or serious injury.
Warning: Indicates a potentially hazardous situation that, if not
avoided, could result in death, serious injury or product damage, and
includes hazards that are exposed when guards are removed.
Caution: Indicates a potentially hazardous situation that, if not avoided, may
result in minor or moderate injury or damage to the product or property.
Note: This shows extra information that may help the reader.
2.2 Safety instructions
• Use the Hibiscus only for the purpose for which it was designed, namely
raking grass and hay.
•
Follow all safety regulations, including those in this manual and
instructions or warnings on the machine.
• Operate the Hibiscus safely.
• The Hibiscus must only be operated by authorised persons.
• Be alert and observe all safety precautions.
• Make sure all safety guards and protection devices are installed and
function correctly.
• Keep people and objects away from moving parts.
• Stop the tractor engine, the Power Take-Off (PTO) and all moving parts
before you do maintenance on the Hibiscus.
• Make sure no people are in the danger zone when the Hibiscus is in
operation. This is especially important when you work near or on areas
that are accessible to the public.
• Make sure there are no objects in the field that could be thrown up by the
Hibiscus before you operate the Hibiscus.
• Obey local legislation when you drive on a public road.
• Use flashing lights or other safety signs, when necessary.
• Do not stand on the Hibiscus.
• Only use genuine LELY parts.
DANGER
WARNING
CAUTION
Note:
Safety 2-1
R-H015-1210EN
• Depressurise the hydraulic system before you connect or disconnect
hydraulic hoses.
•
Use protective clothing, gloves, safety glasses and ear protectors, if
necessary.
• Clean or replace the safety decals regularly so that they can be read at
all times.
2.3 Explanation of the safety decals
Danger: Turning parts.
Keep away from all turning parts unless they
are locked and cannot move.
Danger: Mowing or rotating parts
Read the operating instructions for the PTO
shaft. Always use the correct safety precautions
and protection when you operate the PTO
shaft.
Warning: Maximum operating speed
Never operate the Hibiscus at a PTO speed of
more than 540 rpm
Warning: Hoisting point
Only use the hoisting points indicated on the
Hibiscus to lift the Hibiscus.
Caution: Read manual
Read the operator's manual carefully before
you operate the Hibiscus

Note: Grease point
This indicates a grease point, read the operator
manual for maintenance instructions.

3. OPERATION
3.1 Hydraulic control panel
Read the tractor manual for the correct procedures to operate the
tractor hydraulics.
The operator switches the handle(s) or moves the joystick to operate the
Hibiscus. The following positions of the switches or joystick enable an action
to the hydraulic system:
• Floating (~)
The floating position opens the supply and return valves. The oil pressure
is not available in the system, but passive hydraulic movements are
possible. This position is used when working and disconnecting the
machine.
• Neutral (N)
The neutral position closes the supply and return valves. The oil pressure
is available in the system, but no hydraulic movements are possible.
• Forwards/Reverse
The forward/reverse operations activates the hydraulic system. The
hydraulic operation of the Hibiscus depends on how the hydraulic hoses
are connected to the tractor:
•
Oil flows to cylinders,
• Oil flow returns to tank.

Note:
Operation 3-1
R-H015-1210EN
The hydraulic systems (forward/reverse) marked on the front of the drawbar
are depending on how the connections are made to the tractor.
• Hydraulic system (I):
The hydraulic system (I) moves the Hibiscus from the working position to
the headland position and vice versa. The 3/8" hydraulic hose of the
system is connected to a single acting valve of the tractor.
• Hydraulic system (II):
The hydraulic system (II) folds the Hibiscus in and out between the
transport position and the headland position, but also the working width.
The two 1/4" hydraulic hoses of the system are connected to a doubleacting valve of the tractor.
• Hydraulic system (III) Optional
The hydraulic system (III) makes it possible to lift the rotor independently
from the working position to the headland position and vice versa. The
3/8" hydraulic hose of the system is connected to a single-acting valve of
the tractor.

3.2 Connect the Hibiscus to the tractor
Procedure
1.
Connect the two lower arms of the 3-point hitch to the linkage pins on
the headstock.
2. Use the tractor hydraulics system to lift the headstock until it is level.
3. Unlock the parking jack, swing up the parking jack to the highest
position and lock it in this position.
4. Remove the wheel wedges and attach them to the support behind the
warning sign at the rear of the Hibiscus.
The first time you connect the Hibiscus to each tractor, refer to the
instructions supplied with the PTO shaft and make sure the minimum and
maximum overlap of the two parts of the PTO shaft is correct.
Always connect the safety chain of the PTO shaft to a rigid part of the
tractor.
5. Make sure the Hibiscus PTO shaft telescopes smoothly.
6. Connect the Hibiscus PTO shaft to the tractor PTO shaft.
The maximum pressure of the tractor hydraulic system must not be
more than 21.0 MPa (210 bar).
7. Remove the dust caps from the two 1/4" BSP hydraulic hoses.
8. Connect the two 1/4" BSP hydraulic hoses to the double-acting
hydraulic valve on the tractor.
9. Remove the dust cap from the 3/8" BSP hydraulic hose.
10. Connect the 3/8" BSP hydraulic hose to the single-acting hydraulic
valve on the tractor.
11. If the independent rotor lift (system III) is available:
a. Remove the dust cap from the 3/8" BSP hydraulic hose.
b. Connect the 3/8" BSP hydraulic hose to the single-acting
hydraulic valve on the tractor.
12. Connect the lighting electrical cable to the correct socket on the
tractor.
