Section 10: Introduction

4.1304.8503.0

Splendimo 550 P mowers are designed solely for use in mowing agricultural crops. These machines are not
equipped with any means of crop conditioning. Swath width is adjustable with the use of a swath board or
swath wheel.

DANGER: Rotating blades can throw objects up to 30 m or more,
which can strike motorists or pedestrians.

Do not mow on road right-of-ways including roadside ditches, banks, or
shoulders along traveled highways.

Always use the machine in accordance with the instructions contained in this Operator’s Manual, safety
signs on the machine, and other material provided by Lely.

Proper maintenance and repair is essential for safety, and for efficient operation of the machine. Do not use
the machine if it is not in suitable operating condition.

swivel gearbox pivots from side to side independently of top half. This allows tight turns in any
direction with no concern of damage to PTO shaft (1).

• Splendimo 550 P mowers are configured for 1000 rpm PTO operation only. There is no provision for
field conversion to 540 rpm PTO operation.

• Two independently mounted cutter bars (3) hydraulically fold forward for transport, allowing transport
width of 2.6 m. Cutting width is 5.5 m.

• During operation, mower can be offset to either side of tractor by means of hydraulic cylinder (6).

• The cutter bars are attached to main frame by means of a 3-point linkage with ball joints. As a result,
cutter bars can follow ground contours independently of the main frame.

• Hydraulic cylinder (5) lifts the cutter bars out of the crop. A hydraulic accumulator (7) maintains an
adjustable level of pressure in cylinder (5) while mowing, which provides desired amount of cutter bar

flotation. Refer to page 15-7.

• An adjustable stop on hydraulic cylinder (4) controls pitch of cutter bars and resulting crop stubble

height while mowing. Refer to page 15-5.

10-2 Introduction Splendimo 550 P

Innovators in Agriculture

• Cutter bars are fitted with mower discs, complete with the Lely

4.1304.8503.0

SPLENDIMO CLIP quick-change system (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 (2).

• 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. This configuration helps to reduce power consumption.

• Cutter elements rotate either clockwise or counterclockwise as viewed from

top. Refer to page 50-42.

Mower requires two tractor hydraulic remote valves for proper operation.

Hoses (1) with lock valves supply oil to control valve (5). Depending on position
of controller switch (7), solenoids in control valve (5) direct oil from hoses (1) to
either tongue swing cylinder (4) or cutter bar fold cylinders (not shown).

Hoses (2) without transport lock valves supply oil directly to cutter bar pitch
control cylinder (3) and cutter bar lift cylinder (6).

Cutter Bars - Raise/Lower

Move tractor hydraulic control for remote valve & hoses (2) in one direction to
raise cutter bars, move in the opposite direction to lower. If control movement is
undesirable, switch hoses (2) at remote valve couplers.

When raising cutter bars, pitch control cylinder (3) will retract first, then lift
cylinder (6) will retract.

When lowering cutter bars, pitch control cylinder (3) will extend first, then lift
cylinder (6) will extend.

Some tractors have detents which will not allow the hydraulic control to return
to NEUTRAL on its own. Control must be returned to NEUTRAL manually to
prevent overheating of the hydraulic system. Layout of controls varies with
tractor model. Consult your tractor operator’s manual for further details.

A slight delay in cutter bar raise/lower is normal. Pressure inside lift
circuit accumulator must change accordingly before cutter bars will
raise or lower.

CUTTER BAR FLOTATION

1

45–57 kg

4.1304.8503.0

Correct flotation requires approximately (45–57 kg) ground
force at outer corners of cutter bars as shown.

• Cutter bars should be as light as possible without
missing too much crop due to bouncing.

• Measure ground force by lifting with a spring scale at
outer edge of curtain support frames (1). Cutter bars
should lift off the ground when scale reads 45–57 kg. To
check this, mower must be in operating position and
cutter bars must be fully lowered to the ground.

Check and adjust flotation if one of the following has
taken place:

• Weight has been added to or removed from cutter bars,
including crop debris.

• Mower is operated with a different tractor.

Different tire sizes and PTO shaft heights from one
tractor to another may affect flotation.

• Field terrain conditions have changed.

• Any flotation system components have been changed.

Step 1: Ensure cutter bars are folded out to operating position. Refer to page 15-4.
Step 2: Turn valve handle (2) in front of tongue fully counterclockwise to the open position.
Step 3: Use tractor hydraulic control to fully raise cutter bars. Keep tractor hydraulics

engaged for a few seconds until pressure reading on gauge (1) stops increasing,
then return tractor hydraulic control to the NEUTRAL position.

Pressure reading on gauge (1) should hold steady at maximum tractor pressure.

Step 4: Turn valve handle (2) fully clockwise to the closed position.
Step 5: Move tractor hydraulic control for cutter bar raise/lower circuit to FLOAT position.
Step 6: Slowly turn valve handle (2) counterclockwise until gauge (1) pressure reading

begins to decrease.

Cutter bars will lower as gauge pressure decreases.

Step 7: Turn valve handle (2) fully clockwise to the closed position when gauge reading is

approximately 59 bar (850 psi).

Gauge reading may raise slightly at this point, then should hold steady. Repeat
Steps 6–7 as needed.

Step 8: Move tractor hydraulic control back to NEUTRAL position and check cutter bar

flotation as described on previous page.

Step 9: Gauge reading is only an indication of system pressure. If further adjustment is

necessary to achieve desired flotation as described on previous page, repeat Steps
1–8 as needed.

A higher pressure reading in Step 7 equates to a lighter flotation setting, lower
pressure equates to a heavier flotation setting.

Cutter Bar Balance Assembly - Adjust

Step 1: Swing cutter bar assemblies out to operating position and

leave in the raised position.

Step 2: Adjust spring (3) until the cutter bar is heavier on the inside

of the cutter bar assembly than the outside.

To make heavier:

• Loosen lock nut (1) and tighten lock nut (2).

• Tighten lock nut (1) when after setting is reached.

To make lighter:

• Loosen lock nut (2) and tighten lock nut (1).

• Tighten lock nut (2) when after setting is reached.

result in serious injury or death.

• Stay away from rotating blades.

• Do not lift or reach under cutter bar
deflector curtain.

• Keep all folding shields down.

• Do not operate with cutter bar raised;
blades will be exposed.

• Never allow anyone to ride or stand on
mower. You could fall into blade area.

Follow Shutdown Procedure , page 20-1, before servicing, repairing, and

making any machine adjustments or setting changes.

DANGER: Rotating blades or tines can throw objects 30 m or more.

TRANSPOR T L OCKS - DISENGAGE

Refer to “Transport Locks,” page 15-1.

OPERATING THE MOWER

Step 1: Start tractor engine.
Step 2: Lower cutter bars halfway, then unfold cutter bars to operating position.
Step 3: While driving forward, use tongue swing function to offset mower to left or right side of tractor.

NOTICE: Do not start mower in long crop with cutter bars on the ground. If
mower is started and stopped with cutter bars on the ground in long crop, crop
may wind around discs and plug machine.

Step 4: Engage PTO and increase PTO speed to 1000 rpm before entering standing crop.

WAR NING: Never exceed rated 1000 rpm PTO speed. Excessive speed may cause
blade failure. Excessive speed will cause blades to throw material at a higher
velocity which may penetrate the cutter bar deflector curtains. Serious injury or
death could occur if you are struck by thrown blade or debris.

Step 5: Fully lower cutter bars. Allow adequate time for cutter bars to rest completely on the ground, then

return tractor hydraulic control to NEUTRAL.

Step 6: Slowly move tractor forward.
Step 7: Adjust your ground speed to a safe speed consistent with efficient operation. It may be possible to

travel faster depending on cutting conditions. In other conditions it may be necessary to travel
slower to maintain a safe travel speed.

OPENING THE FIELD

Step 1: In a new field, cut the first round with the mower offset to either side of the tractor.
Step 2: For the second round, travel in the opposite direction to mow the crop laid down by the tractor

wheels in the opening round.

Step 3: Steer mower around obstacles using tongue swing function to minimize tractor steering as

described below.

STEERING THE MOWER

!

1

A

B

C

4.1304.8503.0

NOTICE: While turning sharp corners, extreme care must be taken to ensure
inside rear tractor tire does not contact the tongue. Damage could result to the
tractor tire and the mower. Ground speed may need to be reduced to maintain
stability when making tight turns on sloped ground.

Steering Around Obstacles

Use the tractor hydraulic control to
swing mower left or right around
obstacles.

If swing speed of the tongue is too
fast, adjust flow rate on tractor
hydraulics.

Mower will normally move to the
left slightly slower than to the right
due to the difference in oil volume
needed to move base end vs. rod end of tongue swing cylinder.

Turning Square Corners

Cutter bars should remain lowered throughout the following
steps.

Step 1: As the tractor approaches a corner, adjust the

ground speed to account for terrain and field
conditions.

Step 2: Continue straight past the corner until the rear

wheel of the tractor passes the cut/uncut line (1) of
the crop.

Step 3: Turn sharply toward the uncut material.
Step 4: Straighten out the tractor just enough so that the

inside front tire misses the uncut crop.

Step 5: Position tractor so mower will cut a full-width swath.

180° Turns

To make 180° turns, four or five rounds must
be cut from the perimeter of the field.

Step 1: Continue going straight until the

mower completely cuts the current
swath (A).

Step 2: Immediately raise cutter bars and

turn slightly away from the uncut
crop.

A slight delay in cutter bar raise/
lower is normal. Pressure inside lift
circuit accumulator must change
accordingly before cutter bars will
raise or lower.

Step 3: Turn sharply toward the uncut

crop.

Step 4: At the halfway point of the turn,

reposition mower from left towards
right side of tractor (B).

Splendimo 550 P Operating the Machine 45-5

Innovators in Agriculture

Step 5: As the tractor straightens out alongside uncut crop, swing the mower to cut a full width of uncut

1

4.1304.8503.0

crop (C).

Step 6: Fully lower cutter bars, minimizing disturbance of previously cut crop.

FLOTATION PRESSURE - CHECK

While operating mower, occasionally check flotation pressure reading on gauge
(1).

• With cutter bars lowered, gauge (1) reading should be equal to setting

obtained as result of the last flotation adjustment. Refer to page 15-8.

Pressure may decrease slightly and gradually over time due to normal
amounts of hydraulic system leakage and temperature, but should
generally remain consistent.

When cutter bars are raised, gauge (1) reading will increase. This is
normal.

4.1304.8503.0

Check that PTO shaft shields are in place and rotate freely within the limits of
shield chains (1). Both ends of primary, secondary, and cross PTO shafts (shown)
are equipped with shield chains (1).

PTO shaft shields should be in place to prevent debris from contaminating PTO
shafts and rubbing off anti-friction coating.

Gearboxes

Check all gearbox seals for leakage.

Check gearbox vent plugs to ensure vent caps have not been damaged. If vent
caps are damaged, plugs will need to be replaced.

CURTAIN - CHECK

The cutter bar deflector curtain (A) assembly is an essential part of the safety
equipment provided with the mower. Comprised of separate left and right
curtains, curtain assembly is designed to help prevent materials from being
thrown out from the cutter bar area.

The curtain is designed with a specific shape and material composition to
accomplish this purpose effectively. For your safety, it is essential that the
machine is equipped with a curtain that is in good condition. Damaged
curtains must be replaced.

Use your good judgment and the guidelines in “Curtain - Replace,” page 50-37,

to determine whether a curtain needs to be replaced.

HYDRAULIC SYSTEM - CHECK

WAR NING: Pressurized fluid can penetrate body tissue and result in serious injury
or death. Leaks can be invisible. Keep away from any suspected leak. Relieve
pressure in the hydraulic system before searching for leaks, disconnecting hoses, or
performing any other work on the system. If you must pressurize the system to find
a suspected leak, use an object such as a piece of wood or cardboard rather than
your hands. When loosening a fitting where some residual pressure may exist,
slowly loosen the fitting until oil begins to leak. Wait for leaking to stop before
disconnecting the fitting. Fluid injected under the skin must be removed
immediately by a surgeon familiar with this type of injury.

Ensure all connections are tight and hoses are in good condition before applying pressure to the system.

Check hydraulic lines and fittings for leaks or damage. Check for rubbing or pinching of lines which might
damage the line. Repair or replace as necessary. When a hose with a protective sleeve is replaced, always
install a protective sleeve over the new hose.

CURTAINS - CHECK/REPLACE

4.1304.8503.0

Cutter bar deflector curtains are an essential part of the safety equipment
provided with the mower.

Curtains are designed to help prevent materials from being thrown out from
cutter bar area. They are designed with a specific shape and material
composition to accomplish this purpose effectively.

For your safety, it is essential that the machine is equipped with curtains that
are in good condition. Damaged curtains must be replaced.

Use your good judgment and the following guidelines to determine whether a
curtain needs to be replaced.

Curtain - Replace

A curtain must be replaced when it:

• has a hole, tear or other opening which would allow an object to pass through in a hazardous
manner.

• is worn at the bottom so it is too short.

• has other damage which will reduce its ability to contain flying materials.

When replacing a curtain, use only Lely replacement curtains, which are only available from Lely
dealers. Never use a curtain that is not supplied by Lely. Curtains of a different shape or material may
not provide as much protection from punctures, tearing, or other damage.

SLIP CLUTCH - CHECK

DANGER: Entanglement in rotating PTO shaft can result in death or
serious injury.

Stay away from rotating PTO shaft. Stop engine and ensure PTO shaft is
stopped before working on PTO shaft.

Keep PTO shaft shields in place at all times. Ensure shields turn and
telescope freely.

Wear close-fitting clothing and confine long hair.

The friction discs are spring-loaded, factory-set units which do not require adjustment over the life of the
friction discs. However, after each long period of inactivity, clutch must be slipped to release seized friction
discs before mowing.

Hydraulic Operation - Cutter Bars (Raise)

When operator moves hydraulic control to raise cutter bars, oil flows as follows:

• From tractor to rod end of pitch control cylinder

• From tractor to rod end of take-up cylinder, mounted inside front of tongue
behind valve (1)

Take-up cylinder does not perform any machine control functions. It simply
isolates flotation circuit oil from tractor oil supply.

During normal operation, valve (1) is closed. This will not allow oil to flow
between base end of take-up cylinder and tractor.

Step 1: Because the pitch control cylinder offers oil flow the path of least

Step 2: When pitch control cylinder is fully retracted, oil is forced into the rod end of take-up cylinder.
Step 3: Oil trapped in the base end of the take-up cylinder is forced towards the accumulator, cutter bar

When operator moves hydraulic control to lower cutter bars, oil flows as follows:

• From rod end of pitch control cylinder to tractor

• From rod end of take-up cylinder to tractor

• From tractor to base end of pitch control cylinder

During normal operation, valve (1) is closed. This will not allow oil to flow
between base end of take-up cylinder and tractor.

Step 1: Oil flows from rod end of pitch control cylinder to tractor, and pitch

control cylinder extends. Oil also flows from tractor to base end of pitch
control cylinder.

Step 2: When pitch control cylinder is fully extended, oil flows from rod end of

take-up cylinder to tractor.

Step 3: Oil flows from accumulator and cutter bar lift cylinder into base end of take-up cylinder.
Step 4: When cutter bars reach the ground, there is still oil in the accumulator and rod end of the cutter

bar lift cylinder.

Step 5: Operator moves tractor hydraulic control to NEUTRAL position, cutting off flow of oil to tractor.
Step 6: Compressed nitrogen gas inside the accumulator maintains pressure in the base end of take-up

cylinder and rod end of cutter bar lift cylinder.

Step 7: Pressure in rod end of cutter bar lift cylinder will help support weight of cutter bars, providing

flotation.

Cutter bar flotation is controlled by the amount of oil present in the accumulator
when cutter bars are on the ground. More oil in the accumulator further
compresses the nitrogen gas, which in turn will provide greater pressure in the
rod end of cutter bar lift cylinder and pressure gauge line. Higher pressure
results in cutter bars exerting less ground force and vice versa.

Refer to “Cutter Bar Flotation - Adjust,” page 15-8. Operator fully opens valve

(1), then moves hydraulic control to raise cutter bars. Oil flows as follows:

• From tractor to rod end of pitch control cylinder

• From tractor to rod end of take-up cylinder

• From tractor to base end of take-up cylinder

Step 1: Take-up cylinder extends due to greater force exerted on base end of

piston.

Step 2: Pitch control cylinder retracts.
Step 3: Oil flows to accumulator, cutter bar lift cylinder, and pressure gauge.
Step 4: When pressure of the nitrogen gas and oil inside the accumulator exceeds pressure required to

raise cutter bars, cutter bar lift cylinder will retract and cutter bars will raise.

Step 5: When cutter bars are fully raised, oil flows into accumulator until pressure of nitrogen gas equals

tractor relief pressure setting. Maximum amount of oil is now in the circuit.

Step 6: Operator moves tractor hydraulic control to NEUTRAL, closes valve (1), and moves hydraulic

control to FLOAT position.

Step 7: Operator gradually opens valve (1). This returns excess oil to tractor and reduces accumulator

pressure until desired flotation setting is achieved, at which point valve (1) is closed to resume
normal operation.

WAR NING: Pressurized fluid can penetrate body tissue and result in serious injury
or death. Leaks can be invisible. Keep away from any suspected leak. Relieve
pressure in the hydraulic system before searching for leaks, disconnecting hoses, or
performing any other work on the system. If you must pressurize the system to find
a suspected leak, use an object such as a piece of wood or cardboard rather than
your hands. When loosening a fitting where some residual pressure may exist,
slowly loosen the fitting until oil begins to leak. Wait for leaking to stop before
disconnecting the fitting. Fluid injected under the skin must be removed
immediately by a surgeon familiar with this type of injury.

Before working on hydraulic system, ensure all circuit pressure is relieved as
follows:

Step 1: Fully lower cutter bars.
Step 2: Move tractor hydraulic control to FLOAT position.
Step 3: Open valve (1) and ensure gauge (2) pressure reading drops to zero.

In the event flotation pressure indicated by gauge (2) is lost during operation,
proceed as follows:

Step 1: Check for oil leaks from front of tongue. An oil leak in this area

indicates a loose or leaking fitting, hose, or take-up cylinder.

Step 2: Check for oil leak at cylinder breather (3). A leak here indicates failed

cutter bar lift cylinder piston seal.

Step 3: Check for any other external oil leaks and repair as needed.

If there are no external leaks and adequate flotation pressure still cannot be
achieved, continue below.

Step 4: If cutter bars raise slowly or will not raise, relieve system pressure,

Step 5: Follow steps 1–5 of flotation adjustment procedure on page 15-8. At

disconnect hoses from pitch control cylinder, and cap or plug all
exposed fittings.

• If cutter bars raise normally with pitch control cylinder
disconnected, pitch control cylinder internal seal is leaking.

this point pressure gauge reading should remain constant at
maximum tractor pressure.

• If pressure reading decreases at this point, either valve (4) or
take-up cylinder internal seal is leaking.

• Relieve system pressure, replace valve (4), and repeat Step 5. If
pressure reading still decreases, take-up cylinder internal seal is
leaking.

None of the valve block solenoids are energized when control switch (4)
