1 THE LELY HIBISCUS RAKE

1.1 The Lely Hibiscus 425 S, 455 S and 485 S

Only use the rake for its intended purpose!

The Lely Hibiscus 425 S, 455 S and 485 S are mounted, single-rotor rakes
for side delivery. The rake is equipped with 1 rotor with 11 or 13 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 Hibiscus rake is equipped with a steering device and therefore
behaves like a trailed machine in the field. It can continue raking in
bends without any problem.

The 4–wheel assembly ensures excellent raking when working in
undulating fields.

1.2 Intended Use

The Lely Hibiscus is designed to be used as a rake mounted to and
powered by a tractor.

The rake has been built exclusively for raking grass, hay and straw lying

4.1059.8506.0 A

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 use also implies that the instructions and rules prescribed by the
manufacturer are observed.

1.3 Foreseeable Misuse

The rake must not be operated when stationary or outside an
agricultural field.

The rake must not be used for raking organic waste or hard materials
such as stones.

4 DESCRIPTION

4.1 Lely Hibiscus S

The Lely Hibiscus 425 S, 455 S and 485 S are mounted single-rotor rakes to
rake grass, hay and straw.

The rake has:

• A rotor

• Cam track

• Steering device

• Working height adjustment system

Rotor

The rotor has 11 (425 S, 455 S) or 13 tine arms (485 S), each with four
double tines per arm. The tines provide a clean sweep and move the grass
to the left side of the rake in a fluffy swath. The rotor wheel assembly
supports the rotor and makes sure the rotor follows the ground contour.
For transport the tine arms of the rotor can be removed and stored on
the frame.

Cam track

The adjustable cam track determines the pick and release moment of the
crop.

4.1059.8506.0 A

Steering device

The steering device makes the rake operate as a trailer in the field. The
rake can continue raking when it makes a turn. When the rake is lifted,
the steering device automatically centres the rake behind the tractor. For
road transport, the steering device must be locked.

Working height adjustment system

The rake has a winding handle to adjust the working height of the tines.
The tines should only just touch the ground. The working height can be
adjusted roughly by the position of the rotor wheels.

6-10 Operating Instructions

6.7 Start raking

Make sure no people are near the rake at the moment the PTO is
engaged.

Keep safe distance from people. If a person comes near the rake,
stop the tractor and disengage the PTO.

Switch off the tractor engine and remove the key before leaving
the tractor cabin.

The safety guards and the swath curtain are essential protective
components of the rake. Only operate the rake if these
components have been duly fitted.

Do not drive the rake through the crop when the rotor is on the ground
and is not rotating. This may damage the tines and the tine arm.

Preparation

Make sure the rake is properly adjusted before raking:

If necessary:

4.1059.8506.0 A

• Adjust the swath width (see page 7-1).

• Adjust the working height (see page 7-2).

• Adjust the cam track (see page 7-5).

Procedure

1. Move the three-point hitch upwards to lift the rake from the
ground.

2. 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
rake. Reduce the PTO speed if this occurs.

3. Slowly increase the PTO speed to 450–500 rpm (max. 540 rpm).

4. Drive the tractor at a maximum speed of 12.5 km/h (7.8 mph).

5. Move the three-point hitch downwards to lower the rotor into the
crop.

6. If you want to turn on headlands, move the three-point hitch
upwards to move the rotor to the headland position (see page 6-7).

6.8 Stop raking

1. Stop the tractor.

Operating Instructions 6-11

2. Move the three-point hitch of the tractor upwards to lift the rake
from the ground.

3. Disengage the PTO.

4. Wait for all moving parts to stop.

5. When leaving the field:

1. Put the rake into the transport position (see page 6-3).

6.9 Take the Rake out of Operation

To work safely it is important to take the rake out of operation before
doing maintenance, troubleshooting, making adjustments or before
certain operations. After taking the rake out of operation the tractor and
the rake are standing stable, all parts have stopped and parts will not
move unexpectedly.

To take the rake out of operation:

1. Stop the tractor.

2. Engage the parking brake of the tractor.

3. Disengage the PTO.

4. Wait until all moving parts have stopped.

5. Switch off the tractor engine and remove the key.

6.10 Disconnect the Rake from the Tractor

2. Engage the parking brake of the tractor.

3. Disengage the PTO.

4. Wait until all moving parts have stopped.

5. Switch off the tractor engine and remove the key.

7.1 Adjust the Swath Width

The adjustment depends on the amount of crop and the working width.
Select a position that allows the crop to flow between the rotor and the
swath curtain properly and that prevents the formation of lumps.

1. Take the rake out of operation (see page 6-12).

2. Slide the swath curtain (1) (see figure 24 on page 7-2) to the
required position and secure it with the locking pin (2).

4.1059.8506.0 A

Adjustment 7-1

Figure 24. Adjust the swath width

KEY:

1. Swath curtain - 2. Locking pin

7.2 Adjust 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
curtain and in the direction of travel. The height adjustment system of
the rotor wheels (see figure 25 on page 7-3) is used for rough height
adjustment. The winding handle (see figure 27 on page 7-5) is used for
fine height adjustment.

1. Take the rake out of operation (see page 6-12).

2. Use the top link to tilt the rotor slightly forward in the direction of
travel. The more the top link is shortened, the more the rotor tilts
forward in the direction of travel.

4.1059.8506.0 A

7-2 Adjustment

3. Adjust the rotor height slightly lower at the side of the swath
curtain with the height adjustment system of the rotor wheels (see
figure 26 on page 7-4).

4. Turn the winding handle (1) (see figure 27 on page 7-5) to the
middle of the height adjustment range.

5. Examine the distance of the tines to the ground.

6. If the tines are less than 5 cm (2 in) from the ground:

1. Adjust the height of the tines with the winding handle so

that the tines are only slightly above the ground.

7. If the tines are 5 cm (2 in) or more above the ground:

1. Adjust the height roughly (lower) with the height

adjustment system of the rotor wheels.

2. Adjust the height of the tines with the winding handle so

that the tines are only slightly above the ground.

7.3 Adjust 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. Put the rake into the working position (see page 6-6).

2. Take the rake out of operation (see page 6-12).

3. Remove the lynch pin from the cam track adjustment strip (2) (see
