1 INTRODUCTION
The LELY SPLENDIMO M mower (fig. 1) can be used for mowing
grass fields. A characteristic feature of the SPLENDIMO M mower
is the central attachment of the mower unit allowing optimum
ground contour following.
A tremendous capacity can be realised thanks to the large working
width and high forward speed (up to 15 km/h).
Mowing on slopes up to approx. 20° up and 20° down is within the
machines capability.
The cutter bar is fitted with mower discs, complete with the LELY
SPLENDIMO CLIP quick change system (fig. 2). 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 is driven from the top. A springsteel shaft,
which is driven from the first cutting unit, drives the other units of
the cutter bar. Due to this configuration, only little power is
required.
The elements rotate in pairs, either to the left or right.
The SPLENDIMO M 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.

EN-9
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.
- Attachment position should be so selected 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.
- Lift the headstock to such an extent that the pivot pin of the main
shaft (fig. 4) are approx. 52 cm above ground level.
Check if the mower headstock remains level width-wise. If
necessary, adjust the adjustment of the tractor lever arms.
This adjustment of the tractor’s 3 point hitch 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 eliminating any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO.
At 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.
- Connect the hydraulic hose to a single acting hydraulic tractor
valve.
Maximum allowed oil pressure: 21.0 MPa (210 bar).
- Place the end of the control cord for locking the ram in the tractor
cab.
*. Consult the instruction supplied with the PTO shaft

3 TRANSPORT
The SPLENDIMO M mower can be transported on the tractor’s 3-
point hitch.
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 such lighting and warning signals as are mandatory by
law (or other regulations prescribed by the authorities).
- 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 needed.
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.
Make sure that the abutment pins on the ram are positioned in the
slotted holes of the locking hook (fig. 6).
- Adjust the tractor hitch in such a way that the hinge pin of the
main shaft has a height of 52 cm over ground level (fig. 6). Take
tractor wheelings into account.
Check if the mower headstock remains level width-wise. If
necessary, adjust the adjustment of the tractor lever arms.
Limit a downward movement with, for example, the help of the
stabilisation chains if it is impossible to maintain the adjusted
height of the tractor hitch.
This adjustment of the tractor’s 3 point hitch is essential to
achieve optimum ground following of the mower.
- Make sure that the mower's break back device is in the correct
position and that the machine is positioned straight next to the
tractor.
Lift the mower up to the headland position to push the break back
device into the starting position.
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 Ground pressure
The ground pressure of the SPLENDIMO M mower is set with the
mechanical ground pressure relief system using a tension spring.
If, during operations, the mower has a tendency to float, which
inhibits proper ground contour following, then the traction force of
the spring (= ground pressure relief) should be adjusted at a lower
level.
- Set the ground pressure using the stop plate (fig. 8). The
uppermost hole indicates the lowest ground pressure, the lower
hole the highest ground pressure.

5 OPERATING THE SPLENDIMO®M
• Make sure that nobody is near the machine at the moment
the PTO is engaged.
• Do not allow anyone to come within a 100 m radius from the
machine during work.
• Stop the tractor engine before leaving the tractor cab.
• The safety covers, canopies and plating are essential
protective components of the machine. So: operate the
mower only with these components duly fitted.
•Always operate with the safety cover folded down. Secure it
firmly in the clamp blocks (fig. 9).
For lifting the mower you only need to retract the hydraulic ram.
Lifting of the machine will stop automatically at an inclined position
of approx. 20° up (fig. 10).
The following directions should be followed for operating the
machine:
- 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 up PTO speed up to 540 or 1,000 r.p.m..
This is also the maximum r.p.m. allowed during work.
- Lower the mower into the crop.
- Ensure the floating postition of the hydraulic valve; the ram has
to telescope smoothly throughout the operation.
- Do not drive too slowly; effective working speeds start at approx.
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 of speed may cause crop entanglement in the
cutter bar and/or winding of long crop material underneath the
discs.
- First, lift the mower from the crop and then reduceyour PTO
speed immediately.

EN-13
If the machine does not follow the ground contours effectively, or if
it tends to dig into the ground, the machines ground pressure should
be adjusted (see § 4.2).
Should the machine hit an obstacle during mowing, it can move
backward thanks to the extension of the breakback device (fig. 11).
- The yoke on the R/H lift arm (A, fig. 11) returns automatically
after a minor obstacle has been passed.
- Lift the mower up to the headland position to ensure that the L/H
yoke (B) is returned to the starting position. The ram, which is
integrated in the break back device, will then push the yoke back
automatically.
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 by a bolt
M8x40 - 8.8 Din 933.
- 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, serious
damage may be incurred by the PTO shaft.
Please also be referred 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. 12).
In doing so, 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. 13).
- Depressurize the hydraulic system and disconnect the hydraulic
hose.
- Place the dust cap on the plugsand hang the plug to the support on
the headstock.
- Remove the control cord for the locking hook from the tractor
cab.
- Disengage the top link from the machine.
- Disconnect the lower arms from the machine.

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 has to point downward,
viewed in the direction of rotation of the disc.
The mower knives have two cutting edges. After 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
as well as adhering to the instructions given below. Please be
aware of the fact that an incorrectly fitted mower knife may
cause substantial damage to both objects and people in the
direct vicinity of the SPLENDIMO mower.
- Remove dirt, if any, to be able to access the clip.
- Take the special tool out of its holder on the SPLENDIMO mower
(fig. 20).
- 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. 21).
- 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 has become stuck (B).
- The mower knife is now disengaged and can be replaced by a new
one (C).
