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.

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.
