1 INTRODUCTION
The LELY LOTUS 1325 is a pull-type tedder that is used for tedding
mown grass and spreading out windrows.
High capacity is attainable thanks to the large working width of
13.25 m and high driving speed (up to 15 km/h) at which the ma-
chine can be operated.
The LOTUS tedder is equipped with 3 groups of 4 rotors (fig. 1). Each
rotor is fitted with tine arms featuring double spring steel tines.
The special tine shape ensures that the crop is picked up and spread
out with a minimum loss of material.
Since the rotors can pivot in relation to one another, the LOTUS tedder can follow field undulations with ease.
Ground contours are followed without any problem because the
wheels are positioned closely behind the tines.
Hydraulic controls ensure that the machine can be adjusted to the
transport position quickly and simply. The machine can be transported behind the tractor with ease since its transport width is only 3.0
m.
2 LINKAGE TO THE TRACTOR
Link the machine to the tractor as follows:
- Fit the drawbar to the machine in such a position that the horizontal distance between the pivot point up until the drive shaft is
more or less the same as the distance from the receiving brackets
of the tractor to the PTO (fig. 2).
- Adjust the tractor’s three-point-hitch arms at an equal height.
- Fit the lower arms to the linkage pins (cat. II) of the drawbar.
- Lift the drawbar slightly so that the parking jack is just clear of the
ground. Maintain this height adjustment of the tractor lift during
operation and transport.
- Place the parking jack in the raised position.
- Secure the tractor’s lower arms with stabilisation chains or rods to
eliminate any sideways movements.
- Place the wheel wedges in the supports fitted on the tilting frame
of the rear tedder.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO.
During first assembly or when using another tractor, check
the minimum and maximum overlap of the PTO shaft halves*.
- Fit the safety chain of the protection tube to a rigid part of
the tractor.
- Fold down the support of the PTO shaft.
*. Consult the instructions supplied with the PTO shaft

- Connect the hydraulic hose (A, fig. 3) to a single-acting hydraulic
tractor valve with a floating position.
Permitted maximum oil pressure: 21.0 MPa (210 bar).
- Connect the hydraulic hoses (B + C, fig. 3) to a double-acting hydraulic tractor valve.
B = pressure line, C = return line.
Permitted maximum oil pressure: 21.0 MPa (210 bar).
- Adjust the support (fig. 4) in such a way that the handles can be
operated from the tractor cabin.
- Insert the plug of the lighting cable into the tractor socket
and check if the lighting is operating correctly.
3 TRANSPORT
After the machine has been adjusted to the transport position, it can
be transported by the tractor. The transport width is approximately
3.0 m.
Put the machine into the transport position as follows:
• Pressurise the pressure line of the control block.
Switch the valve or change the insert nipples of the hydraulic
hoses if the hydraulic system does not function in case of any of
the following operations.
• Lift the rotor segments from the ground using the handle c
(fig. 5). The intermediate frame will hereby assume a vertical
position.
• Using handle e, fold up the outer rotor segments and the four
rear rotor segments.
• Using handle d, turn the arms of the lateral rotors forwards.
• Using handle c, lower the arms into the locking system.
• Depressurise the pressure line of the control block.
The oil pump on certain types of tractors may be damaged if it
is subjected to a maximum load for a prolonged period.

- Check whether all rotor segments have been locked (A, B, C,
fig. 6).
- Use all lighting and warning signals required by law (or
other regulations prescribed by the authorities).
- For transport on public roads, ensure that the front axle
weight is sufficient (fit front weights, if necessary) and
that the permitted maximum rear axle weight is not exceeded.
The machine is now ready for transport.
Never allow the PTO shaft to rotate when the machine is in
the transport position.
4 MACHINE ADJUSTMENTS
Ensure that no-one is near the machine when it is switched
from the transport position to the working position.
Put the machine into the working position as follows:
• Pressurise the pressure line of the control block.
Switch the valve or change the insert nipples of the hydraulic
hoses if the hydraulic system does not function in case of any of
the following operations.
• Using handle c (fig. 5), release the arms from the locking sys-
tem.
• Using handle d, turn the arms of the lateral rotors outwards.
• Using handle e, fold out the outer rotor segments and the four
rear rotor segments.
• Using handle c, lower all rotor segments to the ground. The in-
termediate frame will tilt forwards.
• Depressurise the pressure line of the control block.

4.1 Tine adjustment
- Adjust the tines to the outer position (A, fig. 7).
For headland tedding:
Adjust the tines of the rotor on the plot side to the inner position
(B).
4.2 Rotor angle and working height
The wheels have the following preferred setting:
- LOTUS 1325: highest/second-to-highest position.
A more level machine adjustment may be required when handling
light crops or in windy conditions.
- Lift the rotor segments clear from the ground using the tractor's
single-acting hydraulic valve.
- Switch off the tractor engine and take the necessary precautions
to ensure the machine does not suddenly lower before you start
adjusting the wheel supports.
Adjust the wheels to the desired position (fig. 8).
For headland tedding:
Adjust the rotor on the plot side 1 position lower than the remaining rotors.
- Lower the rotor segments again.
The working angle of the rotors in relation to the ground must be
such that the tines sweep the ground gently ensuring adequate crop
pick-up.
Deep adjustment causes an excessive load, which increases
wear and tear as well as the risk of tine breakage. The crop
will also become contaminated more easily.
The stop bushing on the central hydraulic ram (fig. 9) limits the forward tilting movement of the machine.
- Pressurise the double-acting valve.
- Lift the rotor segments from the ground using the handle c. The
intermediate frame will hereby assume a vertical position.
- Turn the stop bushing towards the yoke for a steeper adjustment,
and away from the yoke for a more level adjustment.
- Using handle c, lower all rotor segments to the ground. The intermediate frame will tilt forwards.
- Check the angle of the rotor segments and repeat the aforementioned steps if required.
The central hydraulic ram can be attached to the intermediate frame
in two positions.
• Use the top hole A (fig. 9) for a maximum tedding angle of up
to roughly 15°. This is usually the appropriate position.
• Use the lower hole B for a maximum tedding angle of up to
roughly 18°. In some situations, this position can produce better
tedding results.
Major adjustments to the tedding angle can influence the support
provided by the support frame. Please consult supplement B to adjust this.

5 OPERATING THE LOTUS
®
• Ensure that no-one is near the machine the moment the
PTO is engaged.
• Do not allow anyone to come within a 25 m radius of the
machine during operation.
• Stop the tractor engine before leaving the tractor cab.
• The safety guards are essential protective components of
the machine. For this reason, only operate the tedder if it
these components are duly fitted.
- When using the machine for the first time, carry out the inspection
and maintenance points specified in § 7.3 “Periodic maintenance”
before commencing work.
5.1 General instructions
- Engage the PTO at the lowest possible engine and drive off.
Never drive through the crop with a machine when the rotors are
not moving. This may damage the tines and tine arms.
During the early stage of the process in particular, fast and airy tedding twice a day at a low r.p.m. rate is better than intensive tedding
at a high rotor speed.
The machine can continue operating when taking bends in the field.
- When turning on headlands, lift the rotor segments using the single-acting hydraulic valve.
Keep the machine running at a reduced r.p.m. until the rotor segments are lowered again.
The single-acting hydraulic valve must be in the floating position
during work.
The oblique position of the machine does not change when the single-acting valve is operated.
If the crop is not picked up effectively, verify whether the machine
has tilted forward up until the stop bushing on the central hydraulic
cylinder (handle c). If necessary, adjust the angle of the rotor segments again; see § 4.4.
5.2 Forward speed and PTO speed
Both crop pick-up and spreading depend on the forward speed and
rotor speed.
- Select the highest possible forward speed (up to a maximum of 15
km/h).
- Operate at the lowest possible PTO output (400-450 r.p.m.) so that
the crop is picked up effectively.
- Reduce your PTO output when windrows develop during the tedding operation.
- Adjust the forward speed and PTO speed to field and crop conditions.
Page 15
innovators in agriculture
EN-13
5.3 Recommended 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 (c,
fig. 10).
In windy conditions, drive up and down into the direction of the
wind.
- Adjust the rotor that 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 (d).
6 DISMOUNTING FROM THE TRACTOR
The machine can be dismounted from the tractor both in the working and in the transport position.
Always place the machine on hard, even ground.
- Place the wedges against the transport wheels in order to prevent
the machine from rolling away accidentally.
- Place the parking jack in the bottom position.
- Lower the tractor hydraulics until the parking jack rests on the
ground.
- Switch off the tractor engine.
- Disengage 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.
- Insert the insert nipples of the hoses into the supports (fig. 12).
- Remove the plug for the lighting from the tractor socket.
- Disconnect the lower arms from the machine.

7 MAINTENANCE
• Correct machine servicing is vital for ensuring reliable
and safe operation.
7.1 Maintenance after operation
- Clean the machine thoroughly.
- Check the tines and tine arms for tightness or any damage.
- Grease the machine with an anti-corrosion agent.
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 the machine
will not be used for a long period.
Remove the agent before using the machine again. If this is not
done, the seals of the rams may be damaged when the anti-corrosion agent hardens.
7.2 Lubrication
All lubrication points of the machine can be greased with a biodegradable grease (Total Biomultis SEP2), unless stated otherwise.
- Apply grease to all nipples on the machine (fig. 13).
When greasing the gearboxes, keep turning the rotors bit by bit
to ensure the grease is distributed effectively all over the gears.

A OPTIONAL EXTRAS
Spare wheel with support
To enable a flat tyre to be mended quickly in the field, the LOTUS
tedder can be fitted with a support for a spare wheel.
B ADJUSTING THE SUPPORT FRAME
If major adjustments are made to the tedding angle, the support
points of the support frames of both lateral rotor segments of the
machine have to be adjusted to ensure optimal support.
- Adjust the receiving plates on both sides of the machine so that
they rest on the pivot pins properly. They lateral rotors will only
be optimally supported if this is done (fig. B-1).
The receiving plates can be adjusted after the 6 bolts have been
loosened slightly. Tighten the bolts again properly after the adjustment.
