1 INTRODUCTION
The LOTUS 1020, 1020 SA and 1020 OFFSET are 3-point
linkage tedders with an effective working width of 10,20 m.
A capacity up to approx. 14 ha/h can be achieved thanks to
the massive working width and high forward speed at which
the machine can be operated (up to 15 km/h).
The LOTUS 1020 SA features steered axle wheels to
facilitate manoeuvering in the field or on the farm yard.
The LOTUS 1020 OFFSET model allows an offset position of
the machine behind the tractor.
The LOTUS rotary tedder is fitted with an array of 8 rotors,
each of which has 7 tine arms (fig. 1). The tine arms are
equipped with double springsteel tines. The special tine
shape ensures that the crop is taken up and spread with a
minimum amount of material loss.
The LOTUS tedder follows field undulations easily because
the tedder itself is suspended in a parallelogram construction
and because the rotors can pivot in respect of one another
eliminating the effects that obstacles and field unevenness
might have on the transport wheels.
The machine is adjusted to the transport position quickly and
simply by means of a hydraulic control. Transport in the
tractor’s hydraulic lift is easy because the machine’s trans-
port width is only 3,0 m.

2 MOUNTING BEHIND THE TRACTOR
• Fit the draw bar to the machine in such a position that the
horizontal distance from the pivot point to the drive shaft
approximately equals the distance between the tractor
catch hooks and PTO (fig. 2). This results in an optimum
distribution of the PTO shaft angle ensuring a steady run of
the machine in bends.
• Adjust the tractor lift arms at an equal height.
• Fit the lift arms to the linkage pins of the draw bar.
• Lift the draw bar slightly so that the parking jack is just
clear of the ground. Maintain this height for the tractor
hydraulics throughout operations and transport.
• Pull up the parking jack.
• Fix the tractor lift arms by means of stabilisation chains or
rods to eliminate any sideward movements.
• Check if the PTO shaft telescopes smoothly.
• Mount the PTO shaft to the tractor PTO.
•Fit the safety chain of the protection tube to rigid parts
of the tractor and machine.
• At first assembly, or used of another tractor: check the
minimum and maximum overlap of the shaft halves *).
- Connect the hydraulic hoses with blue marks to a double
acting hydraulic tractor valve, preferably with floating
position. Maximum allowed oil pressure = 17,5 MPa (175
bar).
- Connect the hydraulic hoses with white marks to a double
acting hydraulic valve (preferably with floating position).
Maximum allowed oil pressure: 17,5 MPa (175 bar).
- Put the plug of the lighting cable into the 7-pole tractor
socket.
*) Consult the instruction supplied with the PTO shaft.

2.1 Folding the machine out (working position)
LOTUS 1020:
- By means of the lever for the double acting valve (white
connections) the elements are released from their lock
upon actuating of the lift ram (fig. 3).
- Unfold the elements (fig. 4 and 5) by means of the lever for
the double acting valve (blue connections).
- Operate the lever of the double acting valve (white
connections) to ensure the correct tedding angle of the
rotors (fig. 5) and to lower the outer elements.
- Place the tractor control levers in the floating position (if
available) to ensure optimum ground contour following.
LOTUS 1020 OFFSET:
- Open the ball valve lever (turn to the left) of the ram on the
draw bar (fig. 6) to engage the OFFSET position of the
machine. When unfolding the machine, it will automa-
tically assume the OFFSET position.
- Close the ball valve lever (turn to the right) to disengage
the OFFSET position.

3 TRANSPORT
After the machine has been adjusted to the transport position,
it can be transported by the tractor. Transport width amounts
to 3,00 m.
• Use all such lighting and warning signals as are
mandatory by law.
• 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 exceeded.
3.1 Folding the machine up (transport position)
LOTUS 1020:
- Fold up the elements by means of the lever for the double
acting valve (blue connections).
- Lower the elements in their supports by means of the lever
for the double acting valve (white connections).
LOTUS 1020 OFFSET:
- The transport position is engaged fully automatically. The
machine is released from the OFFSET position and
assumes a central position behind the tractor.
- Lower the elements into their supports.
- Close the ball valve lever (OFFSET cylinder) by way of
additional safety.
•Never allow the PTO shaft to rotate while the machine is
in the transport position.
•Convince yourself of solid transport locking (plates
firmly caught in the hooks, after the elements have been
folded up (fig. 7).
The machine is now ready for transport.

4 MACHINE ADJUSTMENTS
4.1 From transport to working position
Make sure that nobody is near the machine when it is
converted from the transport- to the working position.
- Apply the lever of the single acting valve (blue
connections) to lift the elements from their supports.
- The rotors can be folded down by means of the lever of the
double acting valve (white connections).
- Apply the lever of the double acting valve (white
connections) to lower the outermost rotors.
- Put the levers of the tractor in the floating position (where
fitted).
4.2 Land wheel adjustment
- Adjust the land wheels in the position which ensures the
largest clearance between the rotors and ground level (fig.
8). When having to deal with light crops, or in windy
conditions, a more level machine adjustment may be
required.
- Lift the rotors clear from the ground by means of the
double acting hydraulic valve (white connections).
- Switch off the tractor motor and take precautions to avoid
unexpected lowering of the machine before you are going
to adjust the wheel supports. Now you can proceed to
adjusting the land wheels in the required position.
For raking along plot sides:
Adjust the rotor on the plot side 1 or 2 positions lower than
the other rotors.
- Lower the rotors and ensure the correct tedding angle. For
further information, please refer to chapter 2.1 “Folding
the machine out”.
4.3 Tine adjustment
Adjust the tines in the outer position (A, fig. 9).
For raking along plot sides:
adjust the tines of the rotor on the plot side to the inner
position (B).

4.4 Adjustment of rotor angle
The angle of the rotors in respect of the ground should be
such that the tines stroke the ground with a light pressure and
that they take up the crop adequately.
Deep adjustment causes undue strain which increases
wear and tear as well as the risk of tine breakage. In
addition to this, the crop is bound to get contaminated
more easily.
Forward tilting of the machine is limited by the stop bush
fitted on the central hydraulic ram (fig. 10).
- Lift the elements from the ground by means of the double
acting hydraulic valve (blue connections). The inter-
mediate frame then assumes a vertical position. Now the
stop bush can be adjusted in the required position.
- Apply pressure to the double acting valve (white connec-
tions) to ensure the machine’s tedding angle.

5 OPERATING THE MACHINE
• 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.
If the machine is newly commissioned: first carry out the
check and maintenance duties which are specified in chapter
7.3 “Intermediate maintenance” before starting the operation.
5.1 General directions
• Engage the PTO at the lowest possible RPM; then drive
off.
• Never drive through a crop when the rotors are not
rotating, since this may cause damage to the tines and
tine arms.
Especially in the early stage of the process, fast and airy
tedding twice a day at a low RPM rate is better than intensive
spreading at a high rotor speed.
When bends are taken in the field, machine operation need
not be interrupted.
Lifting the machine on headlands:
- Lift the elements by means of the double acting hydraulic
valve (blue connections) when turning on headlands.
- Keep the machine running at a reduced RPM until the
elements are lowered.
- Apply the lever for the double acting valve (white connec-
tions) to ensure the correct tedding angle. The outer rotors
are lowered at the same time.
39

5.2 Forward speed and PTO-speed
Both pick-up and spreading of the crop are dependent on the
forward speed and rotor RPM.
• Select the highest possible forward speed (up to 15 km/h
as a maximum).
• Operate at the lowest possible PTO output (400 -
450 RPM) always ensuring that the crop is picked up
effectively.
• Reduce your PTO output when “windrows” are formed
during the tedding operation.
5.3 Recommended procedure
- Work the central part of the field by driving up and down.
Leave a strip equal to one working width free on all sides
of the field (, fig. 11). In windy conditions, drive up and
down across the direction of the wind.
- Adjust the rotor which hugs the plot side 1 or 2 positions
lower and adjust the tines of this rotor inwards.
- Finish the plot by driving round and round ().

6 DISMOUNTING FROM THE TRACTOR
The machine can be dismounted from the tractor both in the
working and in the transport position. Proceed as follows:
- Switch off the tractor engine.
- Set the parking jack in the bottom position.
- Lower the tractor hydraulics until the parking jack rests on
the ground.
- Disconnect the PTO shaft from the tractor PTO.
- Place the PTO shaft in the hook.
- Depressurise the hydraulic system and disconnect the
hydraulic hoses. Apply the plastic dust caps to the hose
connectors and place them in the hose support (fig. 13).
- Remove the plug for lighting from the socket in the tractor.
- Uncouple the lift arms from the machine.

7 MAINTENANCE
•Correct machine servicing is essential with a view to
reliable and safe working.
•Machine servicing is necessary with a view to reliable
and safe working.
7.1 Maintenance after operations
• Clean the machine thoroughly.
• Check the tines and tine arms for tightness and damage, if
any.
• Grease the machine with a rust preventive.
Pay special attention to the tines. Smooth tines without any
rust stimulate an unhampered crop flow.
42

7.2 Lubrication
- Apply grease to all nipples on the machine.
When greasing the gearboxes, keep turning the rotors bit
by bit ensuring effective distribution of grease all over the
gears.
- Grease or lubricate all remaining pivot points every 40
working hours. It is strongly recommended to use biolo-
gical grease (FINA BIOMULTIS SEP2).
