1 INTRODUCTION
The LOTUS 1325 is a 3 point linkage tedder with an effective
working width of 13,25 m. A capacity up to approx. 18 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 1325 tedder comprises of 3 groups of 4 rotors
(fig. 1). Six tine arms with double springsteel tines are fitted
to each rotor. The special tine shape ensures that the crop is
taken up and spread with a minimum amount of material loss.
The rotors pivot in respect of one another allowing the
LOTUS tedder to easily follow field undulations.
Following irregular ground contours is also facilitated by the
fact that the wheels are positioned close to the tines.
The machine is adjusted to the transport position quickly and
simply by means of a hydraulic control. Transport on the
tractor’s hydraulic lift is easy because the machine’s
transport width is only 3,00 m.
2 MOUNTING BEHIND THE TRACTOR
- Mount the drawbar to the machine in such a position that
the horizontal distance of its point of rotation in respect of
the drive shaft is approximately equal to the distance of the
catch hooks of the tractor in respect of the tractor PTO (fig.
2).
- Adjust the tractor’s three point hitch lower arms at equal
height.
- Fit the lower arms to the linkage pins of the bar.
- Lift the drawbar slightly so that the parking jack is just
clear of the ground. Maintain this height adjustment of the
tractor lift during operations and transport.
- Place the parking jack in the raised position.
- Secure the tractor’s lower arms by means of stabilisation
chains or rods eliminating any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Mount the PTO shaft to the tractor PTO.
At first assembly, or use of another tractor: check the
minimum and maximum overlap of the shaft halves
(Consult the instruction supplied with the PTO shaft.)

- Fit the safety chain of the protection tube to a rigid part of
the tractor.
- Fold down the PTO shaft support.
- Connect the hydraulic hose (A, fig. 3) to a single acting
hydraulic tractor valve with floating position.
Max. allowed oil pressure: 17,5 MPa (175 bar).
- Connect the hydraulic hoses (B+C, fig. 3) to a double
acting hydraulic valve.
B=pressureline,C=returnline
Max. allowed oil pressure: 17,5 MPa (175 bar).
- Adjust the support (fig. 4) in such a way that the levers can
be controlled from the tractor cab.
- Put the plug of the lighting cable into the 7-pole tractor
socket.
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.
- Adjust the machine to the transport position as follows.
• Pressurize the pressure line of the control block. Switch
the valves or exchange the valve connectors of the hoses
if the hydraulic system does not function during any of
the following procedures.
• Lift the rotors clear from the ground by means of lever
(fig. 5). The intermediate chassis will then adjust to
the vertical position.
• Apply lever to fold up the outer rotors and the four
rear rotors.
• Turn the arms and the side fields forwards by means of
lever .
• Apply lever to lower the arms into the locking
system.

• Remove the pressure from the pressure line of the control
block. The oil pump of certain tractor models may incur
damage as a result of sustained load.
- Makesureallrotorsaredulylocked(A,B,C-fig.5).
The machine is now ready for transport.
Never allow the PTO shaft to rotate while the machine is in
the transport position.
4 MACHINE ADJUSTMENTS
4.1Conversion to the working position
Make sure that nobody is near the machine when it is
converted from the transport- to the working position.
- Proceed as follows to obtain the working position of the
machine.
• Pressurize the pressure line of the control block. Switch
the valves or exchange the valve connectors of the hoses
if the hydraulic system does not function during any of
the following procedures.
• Apply lever to lift the arms from the locking system
(fig. 5).
• Move the arms and side rotors sideways by means of
lever .
• Apply lever to unfold the outer rotors and the four
rear rotors.
• Lower all rotors onto the ground by means of lever .In
the process, the intermediate chassis will tilt forwards.
• Remove the pressure from the pressure line of the control
block.

4.2Adjustment of wheel supports
- Lift the rotors clear from the ground by means of the single
acting hydraulic tractor valve.
- Adjust the land wheels in the position which ensures the
largest clearance between the rotors and ground level (fig.
7).
When having to deal with light crops, or in windy
conditions, a more level machine adjustment may be
required.
For raking along plot sides:
adjust the rotor on the plot side 1 or 2 positions lower than
the remaining rotors.
- Lower the rotors.
4.3Tine adjustment
- Adjust the tines in the outer position (A, fig. 8).
For raking along plot sides:
adjust the tines of the rotor on the plot side to the inner
position (B, fig. 8).
4.4Adjustment 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 abutment
bush fitted on the central hydraulic ram (fig. 9).
- Pressurize the double acting valve.
- Lift the rotors clear from the ground by means of lever .
The intermediate chassis will then adjust to the vertical
position.

- Turn the abutment bush towards the yoke if a steeper
adjustment is needed. If a more level adjustment is
required, the abutment bush should be turned away from
the yoke.
- Lower all rotors onto the ground by means of lever .In
the process, the intermediate chassis will tilt forwards.
- Check the angle of the rotors and, if necessary, repeat the
above mentioned proceedings.
5 OPERATING THE LOTUS®
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 § 7.3
(Intermittent Maintenance) before starting the operation.
5.1General directions
- Engage the PTO at the lowest possible r.p.m. rate; then
drive away.
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 r.p.m. rate is better than
intensive spreading at a high rotor speed.
When bends are taken in the field, machine operation need
not be interrupted.
- When turning on headlands, lift the rotors by means of the
single hydraulic valve.
Keep the machine running at a reduced r.p.m. until the
fields are lowered again.
32
!

During operations, the single acting hydraulic valve has to be
in the floating position.
Forward tilting of the machine does not change if the single
acting valve is actuated.
If the crop is not picked up effectively: check if forward
tilting of the machine is checked by the stop block on the
central hydraulic ram (lever ). If necessary, re-adjust the
angle of the rotors; see § 4.4.
5.2Forward speed and PTO speed
Both pick-up and spreading of the crop are dependent on the
forward speed and rotor r.p.m. speed.
- Select the highest possible forward speed (up to 15 km/h as
a maximum).
- Operate at the lowest possible PTO output (400 -
450 r.p.m.) always ensuring that the crop is picked up
effectively.
- Reduce your PTO output when “windrows” are formed
during the tedding operation.
5.3Recommended procedure
- Work the central part of the field by driving up and down.
Leave a strip equal to 1 working width free on all sides of
the field (, fig. 10). 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.
- Switch off the tractor engine.
- Set the parking jack in the bottom position.
- Lower the hydraulic lift until the parking jack rests on the
ground.
- Disconnect the PTO shaft from the tractor PTO.
- Place the PTO shaft on the support (fig. 11).
- Depressurize the hydraulic system and disconnect the
hydraulic hoses. Place the hose connectors in their
supports (fig. 12).
- Remove the plug for lighting from the socket in the tractor.
- Uncouple the lower arms from the machine.
7 MAINTENANCE
Correct machine servicing is necessary with a view to
reliable and safe working.
7.1Maintenance 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.
- Grease the piston rods with an anti-corrosion agent if a
longer period of inactivity is anticipated. Remove the agent
when putting the machine back into operation. If not,
sealing of the ram may be affected after hardening of the
anti-corrosion agent.
