1 INTRODUCTION
The LELY SPLENDIMO 240 MC is a mower conditioner suitable
for mowing grass. A characteristic feature of the SPLENDIMO MC
mower is the central attachment of the mower unit, which allows
optimum ground contour following.
The machine can mow on slopes up to approximately 20° up and 20°
down.
The machine is built up of a cutter bar and a conditioner unit.
The cutter bar is fitted with mower discs, complete with the LELY
SPLENDIMO CLIP quick-change system (fig. 1). The cutter bar is
composed of cutting units according to the modular LELY system.
These elements as well as the intermediate spacers are torqued
together by a connecting rod.
The first cutting unit (drive element) is driven from the top. A
spring-steel shaft, which is driven from the first cutting unit, drives
the other units of the cutter bar. Only minimal power is required
thanks to this configuration.
The elements rotate in pairs, either to the left or right.
The IMPELLER conditioner unit (fig. 2) comprises a rotor fitted
with fingers made of an impact-resistant synthetic material, a metal
hood with swathboards as well as a crop inlet plate for adjusting the
conditioning intensity.
The conditioner unit operates over almost the entire cutting width.
Crop treatment is such that patches of the waxy layer on the stem are
removed and thick stems are broken. The crop is turned slightly and
laid down behind the machine in an airy, narrow swath. There is
therefore minimum contact between the crop and the moist field,
and there is no need to drive on mown crops.
The SPLENDIMO 240 MC mower can be controlled with just one
hydraulic ram. Ground pressure can be adjusted in 3 positions by
repositioning the stop plate of the spring assembly.
A breakback device prevents damage to the machine if an obstacle
is hit.

2 LINKAGE TO THE TRACTOR
The headstock is fitted with double linkage pins (category II). This
allows the mower to be attached to the tractor with more or less
offset (fig.3).
In most conditions, position cis recommended for coupling.
Always use position dwhen mowing down a descending slope so
that you can operate as far from the side as possible.
- Choose an attachment position so that the first mowing disc is
entirely offset from the track of the tractor tyre.
- Fit the lower arms to the linkage pins of the machine’s headstock.
- Fit the tractor top link to the machine.
- Connect the hydraulic hose for lifting the machine to a single-
acting hydraulic spool valve with floating position.
Permitted maximum oil pressure: 21.0 MPa (210 bar).
- Lift the headstock to such an extent that the hinge pin of the main
shaft (fig.4) is approximately 54 cm above the ground.
Check if the mower headstock remains level width-wise. If
necessary, adjust the tractor lever arms.
This adjustment of the tractor hydraulics is essential to
achieve optimum ground following of the mower.
- Place the parking jack in the raised position.
- Secure the tractor’s lower arms by means of stabilisation chains
or rods to eliminate any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO.
During first assembly or use of 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.
- Place the end of the control cord for locking the ram in the tractor
cab.
*. Consult the instructions supplied with the PTO shaft

3 TRANSPORT
The SPLENDIMO MC mower can be transported on the tractor
hydraulics.
Put the machine into the transport position as follows:
- Pull up the locking hook for the hydraulic ram and retract the ram
completely.
- Check if the ram is secured by the locking hook (fig.5).
- 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.

EN-11
4 MACHINE ADJUSTMENTS
Put the machine into the working position as follows:
- Pull up the locking hook of the hydraulic ram for a moment and
lower the cutterbar carefully by means of the ram.
Ensure that the abutment pins on the ram are positioned in the
slotted holes of the locking hook (fig. 6).
- Adjust the tractor hydraulics in such a way that the hinge pin of
the main shaft is located 54 cm above the ground (fig. 6). Take
tractor wheelings into account.
Check if the mower headstock remains level width-wise. If
necessary, adjust the tractor lever arms.
Limit a downward movement with stabilisation chains, for
example, if it is impossible to maintain the adjusted height of the
tractor hydraulics.
This adjustment of the tractor hydraulics is essential if the
mower is to follow the ground contour as effectively as
possible.
4.1 Mowing height
- Adjust the mowing height by adjusting the forward inclination of
the cutter bar with the aid of the top link (fig. 7).
4.2 Intensity of conditioning
The intensity of conditioning can be adjusted by means of the
conditioner's crop inlet plate (fig. 8) and the rotor speed.
- Adjust the crop inlet plate.
Position A ensures the highest intensity of conditioning, whereas
it is lowest when the crop inlet plate is adjusted to position B.
There are five intermediate positions.
If the adjustment possibilities of the conditioner crop inlet plate do
not allow sufficient crop flow-through, the position of the crop inlet
plate and the rotor speed may be adjusted. Please refer to
supplement B for more details.

4.3 Ground pressure
The ground pressure of the SPLENDIMO MC mower is set with the
mechanical ground pressure relief system using a tension spring.
If the mower tends to float during operation, which inhibits proper
ground contour following, the traction force of the spring (= ground
pressure relief) should be adjusted to a lower level.
- Set the ground pressure using the stop plate (fig. 9). The upper
hole indicates the lowest ground pressure while the lower hole
indicates the highest ground pressure.
4.4 Swath width
The swath width of the SPLENDIMO 240 MC mower can be
adjusted from 0.7 up to 2.4 m.
- Use the adjusting device (fig. 10) to obtain the required opening
of the swath-board. Then lock the adjusting device.

5 OPERATING THE SPLENDIMO®MC
• Ensure that nobody is near the machine the moment the
PTO is engaged.
• Do not allow anyone to come within a 100 m radius of the
machine during operation.
• Stop the tractor engine before leaving the tractor cab.
• The safety covers, canopies and plating are essential
protective components of the machine. That is why the
mower must only be operated when these components are
duly fitted and in a good condition.
•Always operate the mower with the safety cover folded
down. Secure it firmly in the clamp blocks (fig. 11).
To lift the mower, you only need to retract the hydraulic ram.
The machine will stop lifting automatically at an inclined position
of approximately 20° (fig. 12).
Always lift the mower up to the stop to ensure sufficient ground
clearance.
The mower must be operated as follows:
- Lower the machine by means of the hydraulic ram until it is just
above crop level.
- Engage the PTO at the lowest possible engine r.p.m..
- Then rev the PTO speed up to 540 or 1,000 r.p.m.
This is also the maximum r.p.m. permitted during work.
- Lower the mower into the crop.
- Place the hydraulic valve in the floating position; smooth
telescoping of the ram must be ensured at all times.
- Do not drive too slowly; effective working speeds start at
approximately 10 km/h. A lower speed may affect crop flow-
through across the cutter bar.
- Make sure that the PTO speed of 540 or 1,000 r.p.m. is maintained
during work.
A (temporary) drop in speed may cause crop to become entangled
in the cutter bar and/or long crop material to wrap around the
discs.
- Lift the mower from the crop first and then reduce your PTO
speed immediately.
If the machine does not follow the ground contours effectively, or if
it tends to dig into the ground, the machine's ground pressure should
be adjusted (see § 4.2).

EN-14
If the machine hits an obstacle during mowing, it can move
backwards thanks to the extension of the breakback device (fig. 13).
- After extension of the breakback device, reverse a few meters
until the breakback device has locked back into position.
The machine is protected against overload by either a slip clutch or
a shear bolt clutch.
- Replace a broken shear bolt of the shear blot clutch with an
M8x40 - 8.8 Din 933 bolt.
- If the machine needs to be placed in the transport position at the
end of its operation, wait until all moving parts have come to a
standstill.
When folding up a machine with rotating parts, the PTO shaft
can be seriously damaged.
Please also refer to chapter 3 “Transport”.
6 DISMOUNTING FROM THE TRACTOR
Always place the machine on hard, even ground.
- Lower the mower.
- Lower the tractor hydraulics until the abutment pins of the ram are
positioned in the hooks of the locking device (fig.14).
Pull the control cord of the locking hook to position the hooks in
line with the abutment pins.
- Place the parking jack in the bottom position.
- Lower the tractor hydraulics further 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 in the parking chain (fig. 15).
- Depressurize the hydraulic system and disconnect the hydraulic
hose.
- Place the dust cap on the plug and hang the plug on the headstock
support.
- Remove the control cord for the locking hook from the tractor
cab.

7 MAINTENANCE
• Correct machine servicing is vital for ensuring reliable and
safe operation.
• Install supports underneath the cutter bar if it is lifted from
the ground and you intend to carry out work underneath it.
The cutter bar can be accessed more easily for maintenance work by
opening the front safety shield. Proceed as follows:
- Fold up the front safety cover and secure it with the hook
underneath.
7.1 Maintenance after operation
- Clean the machine thoroughly. After jet-cleaning, allow the discs
to rotate briefly so that the water is flung away.
- Check the mower knives and discs for tightness and damage
(torques: see § 7.3).
- Check the safety cover for damage.
- Grease the machine with an anti-corrosion agent.
- Grease the piston rod with an anti-corrosion agent if a longer
period of inactivity is anticipated.
Remove the agent before using the machine again. If not, the seals
of the rams may be affected if 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.
- PTO shafts must be greased every 8 working hours via the grease
nipples on the cross assemblies, protection tubes and free wheel
clutch (fig. 16).
- Grease profiled tubes of the PTO shaft every 8 working hours
(fig. 16).
- Grease the pivoting points of the main shaft every 40 working
hours (A, fig. 17).
- Grease the pivot point of the spring arm (B, fig. 17) every 40
working hours.
- Apply a few drops of oil to the cams of the breakback device
every 40 working hours (fig. 18).

7.3 Intermittent maintenance
Intermittent maintenance has to be carried out:
• at the start of the mowing season;
• before prolonged storage of the machine;
• when the machine is used extensively during the season.
- Grease all points of the machine listed in § 7.2 “Lubrication”.
- Grease the spring-loaded locking pins of the yoke lock of the PTO
shaft.
- Check if the PTO shafts telescope smoothly.
A damaged PTO shaft may cause excessive wear and tear to the
machine and tractor.
- Check whether the spring of the breakback device is correctly
pretensioned at a length of 160 mm (fig. 18).
- Check the V-belts for correct tension.
To do so, open the V-belt housing. The tension should be such
that each V-belt can be pushed in (fig. 19) between the pulleys by
approximately 10 mm when applying a force of 70 N (7 kg).
It is recommended to depressurize the V-belts if the machine will
not be used for a long period of time.
- Check the condition of the wear plates, mower discs and knives
(replacement of knives: see § 7.4).
- Check the knife pins for tightness (fig. 20).
The clip must be properly locked by the cam of the mowing disc.
- Check the mower discs for tightness (fig. 20). The castellated nut
torque is 150-250 Nm (15-25 kgm). The split pin locking the
castellated nut may not protrude above the pressure piece.
Attention: the nut may not be turned back; keep turning it until the
split pin can be fitted.
- Check the machine for any damage and flaws.
- Check the gearboxes for any oil leaks.

7.4 Replacement of knives
The mower knives come in 2 different versions for discs with LH or
RH rotation. The front of the cutting edge must point downward,
viewed in the direction of rotation of the disc.
The mower knives have two cutting edges. When one edge is worn,
the knife can be reversed so that the second edge can be used.
Knives should always be replaced in pairs in order to keep the disc
balanced.
Mower knives should be changed with great care and attention
in accordance with the instructions provided below. Please be
aware that an incorrectly fitted mower knife can cause
substantial damage to both objects and people in the direct
vicinity of the SPLENDIMO mower.
- Remove any dirt to obtain proper access to the clip.
- Remove the special tool from its holder on the SPLENDIMO
mower (fig. 23).
- Turn the mowing disc in such a way that the pin of the knife to be
changed is positioned over the hole in the skid.
- Place the fork of the tool behind the clip (A, fig. 24).
- Move the tool downwards so that the clip is released from the
locking cam and comes off the knife pin.
- Remove the clip.
- Remove the knife pin. If necessary, use the pointed hammer of the
tool to disengage the pin if it is stuck (B).
- The mower knife is now disengaged and can be replaced with a
new one (C).
- Examine the knife pin for wear and tear. If wear and tear is
clearly visible, the knife pin should no longer be used.
- Always ensure the knife pin is locked with a new clip.
- Mount the parts in the reverse order.
- Position the mower knife with the pin underneath the mowing
disc.
- Install the clip so that it matches the groove in the knife pin (D).
- Use the tool (E) to hammer the clip into the groove of the knife
pin completely so that it is firmly locked by the locking cam of the
