1 INTRODUCTION
The LELY SPLENDIMO T is a disc mower which is used for mowing grass lands and road sides. Mowing on slopes up to
approx. 10° up and 10° down is within the machine’s capability.
The machine is fitted with discs of the “S” or “N” model (fig.
1).
The cutter bar is composed of cutting units according to the modular LELY system. These elements as well as the inter-
mediate 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.
Cutting units rotate either to the left or right. Standard configurations are shown in fig. 2.
If required, the cutting units of the SPLENDIMO T mower with “S” model discs can be fitted in a different confi-
guration.
The SPLENDIMO T mower can be controlled with just one hydraulic ram.
A breakback device prevents damage to the machine if an obstacle is hit.

2 MOUNTING BEHIND THE TRACTOR
The headstock is fitted with adjustable linkage pins (category II) for adjustment of the offset position of the machine
behind the tractor (fig. 3). Always use position ‚ when mowing down a descending
slope so that you can operate as far from the side as possible.
- Adjustment of the linkage pins should be so selected that the drive element is entirely offset from the track of the tractor tyre.
- Adjust the tractor 3 point hitch lower arms at equal height.
- Fit the lower arms to the linkage pins of the machine’s headstock.
- Fit the tractor top link to the machine by means of a category II top link pin.
- Lift the headstock to such an extent that the hinge pin of the intermediate chassis (fig. 4) is approx. 74 cm above ground level.
- Place the parking jack in the raised position.
- Secure the tractor lever arms by means of stabilisation chains or rods keeping the mower from making sideward movements.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO shaft.
At first assembly or use of another tractor: check the minimum and maximum overlap of the PTO halves *.
In addition to this, you should check for sufficient overlap when the anti-shock device goes into operation
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 that has a floating position.
- Place the end of the control cord for locking the ram in the tractor cab.
- Check if the lever arms remain at an equal height when the cutter bar is folded up.
* Consult the instruction supplied with the PTO shaft.

3 TRANSPORT
The SPLENDIMO T disc mower can be transported on the tractor’s 3 point hitch.
- The locking hook for the hydraulic ram will automatically engage and lock during retraction.
- Check if the ram is secured by the locking hook (fig. 5).
- Use all such lighting and warning signals as are man- datory 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.
- When transporting the SPLENDIMO 360 T mower, take its transport height of over 4,00 m into account.
The machine is now ready for transport.
4 MACHINE ADJUSTMENTS
- Pull up the locking hook of the hydraulic ram and lower the cutter bar carefully by means of the ram.
- Adjust the tractor hitch in such a way that the hinge pin of the intermediate chassis has a height of 74 cm over ground level (fig. 4). Take tractor wheelings into account. Limit a downward movement with, for example, a stabi­lisation chain (optional extra) if it is impossible to maintain the adjusted height of the tractor hitch.
- Adjust the mowing height by adjusting the forward incli­nation of the cutter bar with the aid of the top link (fig. 6).
- Fold down the safety cover and secure it firmly in the clamp block (fig. 7).
When steep slopes are mown, crop flowthrough may be affected by the swathboard. If so, remove the swathboard and
its support.

5 OPERATING THE MACHINE
• Always operate with the safety cover folded down.
• 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.
For lifting the cutter bar you only need to retract the hydraulic ram.
The cutter bar will first be raised approx. 10° (fig. 8), after which it is lifted from the ground. The cutter bar then folds up further until the locking hook hits the mower frame (fig.
9). This allows quick turning on headlands.
For total folding of the cutter bar, the locking hook needs to be pulled up.
Mind the following directions when working with the mower.
- Lower the cutter bar by means of the hydraulic ram until it is just above crop level.
Engage the PTO shaft at the lowest possible engine RPM.
- Then rev up PTO speed up to 540 RPM which is the maximum RPM allowed during work.
- Lower the cutter bar into the crop.
- Ensure the floating position 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 RPM is maintained during work. A (temporary) drop of speed may cause crop entanglement in the cutter bar and/or winding of long crop material around the discs.
- First, lift the cutter bar from the crop and then reduce your PTO speed immediately.

- If the machine, at the end of operation, needs to be put in the transport position, wait until all moving parts of the
machine have come to a complete standstill.
When folding up a machine that is still running, serious damage may be done to the PTO shaft.
Also see chapter 3 “Transport”.
Should the cutter bar hit an obstacle during mowing, it can move backward thanks to the extension of the breakback
device (fig. 10). After extension of the breakback device: drive backwards a
few meters until the breakback device has locked back into position.
6 DISMOUNTING FROM THE TRACTOR
- Lower the cutter bar.
- Switch off the tractor engine. Disengage the PTO shaft from the tractor PTO.
- Place the PTO shaft in the hook (fig. 11).
- Set the parking jack in the lowest position.
- Lower the three point hitch until the parking jack is supported by the ground.
- Depressurize the hydraulic system and disconnect the hydraulic hose.
- Disengage the top link from the machine.
- 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. After jet-cleaning allow for a few moments rotation of the discs so that the water is swept away.
- Check the mower knives and discs for tightness and damage (see § 7.3).
- Check the safety cover for damage.
- Grease the machine with a rust preventive.
- Grease the piston rod 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.
7.2Lubrication
- PTO shaft to be greased every 8 working hours by the grease nipples on the cross assemblies, protection tubes and free wheel clutch (fig. 12).
- Profiled tubes of the PTO shaft to be greased every 8 working hours.
- Grease the PTO shaft above the drive element every 100 working hours in way of the grease nipples on the cross
assemblies. For this purpose, the cover A (fig. 13) and the sealing plate B have to be dismounted. Remove soil and/or crop material, if any, from the hat.
- Grease the pivots of the intermediate frame every 40 working hours.
- Grease or lubricate all remaining pivot points every 40 working hours.
- Apply a few drops of oil to the cams of the breakback device every 40 working hours (fig. 14).

7.3Intermittent maintenance
Intermittent maintenance has to be carried out:
• at the start of the haymaking season.
• before prolonged storage of the machine.
• when the machine is used extensively during the season.
- Grease the PTO shaft.
- Grease the profiled tubes of the PTO shaft .
- Grease the spring-loaded locking pins of the yoke lock of the PTO shaft.
- Check if the PTO shaft telescopes smoothly. A damaged PTO shaft may cause excessive wear and tear to the machine and tractor.
- Grease the PTO shaft above the drive element in way of the grease nipples on the cross assemblies. For this purpose,
the cover A (fig. 13) has to be removed. Remove soil and/or crop material, if any, from the hat.
- Grease the pivots of the intermediate frame (fig. 15).
- Grease or lubricate all remaining pivot points.
- Apply a few drops of oil to the cams of the breakback device (fig. 14).
- Check correct prestress of 160 mm of the spring of the breakback device (fig. 14) fitted to the SPLENDIMO 240 /
280 T disc mowers. The disc mower SPLENDIMO 320/ 360 T has, in stead of the spring, a rubber bloc which needs
to be compressed up to a length of 95 mm.
- Check the machine for damage and flaws.
- Check the condition of wear plates, mower discs and knives (for knife replacement - see § 7.4).
- Check the knife bolts for tightness. Type “S” (fig. 15): lock bolts with Loctite 243 or use new bolts and locking agent. Torque: 50-60 Nm (5-6 kgm). Type “N” (fig. 18): torque 50-60 Nm (5-6 kgm).
- Check the mower discs for tightness (fig. 15/16). Torque: 150-250 Nm (15-25 kgm). The split pin locking the
castellated nut is not allowed to protrude above the pressure piece.
We recommend that you first tighten the nut to the minimal torque and then keep turning until the split pin can be fitted.

7.4Replacement 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 (fig.
19).
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.
- Replace worn or damaged nuts and knife bolts.
- Type “S”:
- use new knife bolts together with a locking agent, or
apply Loctite 243 to the threaded part of the bolt;
- tighten the knife bolts with a torque of 50-60 Nm
(5-6 kgm).
- Type “N”:
- use new, self-locking nuts and tighten them with a torque
of 50-60 Nm (5-6 kgm).
7.5Change of oil in gearboxes
Change the oil of the gearboxes and the drive element of a new mower (or after assembly of a new gearbox) after approx. 30 working hours for the first time. After that, oil has to be changed every 250 working hours.
- Fill the gearbox A (fig. 20) with 1.7 l transmission oil (GX85W140).
- Fill the gearbox B (fig. 21) with 0.85 l transmission oil (GX85W140).
- Fill the drive element C (fig. 21) with a carefully measured quantiry of 0.45 l transmission oil (GX85W140).
An incorrect oil quantity may lead to overheating and damage of the element.
Remove the wear plate to gain access to the draining/ filling plug. Tilt the cutter bar slightly backwards for oil removal. For filling the drive element, the cutter bar has to be tilted forwards.
Change the oil in the drive element more often when operating the machine in exacting conditions.

7.6Change of grease in mower elements
Replace the grease in the mower elements every 500 working hours or every 1,000 hectares.
Follow the directions listed hereafter.
- Remove the mower disc.
- Dismount the bearing housing A (fig. 22) from the element. Make sure that the shims B remain in place.
If several bearing housings need to be dismounted, care should be taken that they are fitted back on the original mower elements .
- Remove the grease from the element. Do not use a solvent since it may affect the sealing of the bearings and/or rinse
the grease fill out of the bearings.
- Fill the elements with 95 grams of grease (grease classi­fication NLGI 0, type calcium-lithium soap or lithium soap/Shell Alvania WR 0).
Measure the grease quantity carefully. An incorrect quantity may cause overheating and damage of the
element.
- Place the bearing housing on the element. Turn the hub C (fig. 22) so that it is aligned with the hub of the adjacent mower element (fig. 23).
- Apply Loctite 243 to the thread of the M8 fillister head screw and tighten them with the following torques: 36 Nm (3,6 kgm) for mower unit with castellated nut M22.
- Check the presence of the O-ring in the pressure piece.
- Fit the mower disc. Tighten the castellated nut with a torque 150-250 Nm (15-25 kgm) and secure it with a split pin. Make sure that the split pin does not protrude above the pressure piece.

A CUTTER BAR
ASSEMBLY/DISASSEMBLY
The figures placed between brackets correspond with the numerals in figure A-1.
The cutter bar is built up of independent units (1). These mower elements are kept apart by intermediate spacers (2). The units and spacers are kept together by a connecting rod (3).
The cutting units are driven from the drive element (4) by a drive shaft (5).
Thanks to the modular design, mower elements can be replaced quickly, as can the drive shaft. If so required, the sequence of elements with LH and RH rotation can be changed in the SPLENDIMO T disc mower with “S” model mower discs.
Dismount the cutter bar as follows.
- Mount the machine in the tractor’s three point hitch.
- Place the machine on a level floor.
- Remove the securing plate (6).
- Untighten the nut M30 (7) by a few turns.

- A RH rotation SPLENDIMO T disc mower element can
be identified as follows. When the hub is turned to the right (R: fig. A-4) the drive
gear on the RH side will turn anti-clockwise (viewed from the rear).
- A LH rotation SPLENDIMO T disc mower element can
be identified as follows. When the hub is turned to the left (L: fig. A-4), the drive
gear on the RH side will also turn anti-clockwise .
Make sure that the mower discs are turned 90° in respect of one another. If a unit can not be slid onto the drive shaft
in one go, its disc needs to be turned a semi-turn one or several times until the unit can be placed.
- After disassembly of a disc:
• check the presence of the O-ring in the pressure piece
(11, fig. A-1).
• Tighten the castellated nut (12) with a torque of 150-250
Nm (15-25 kgm) and secure it with a split pin. Make sure that the split pin does not protrude above the pressure piece.
- The securing disc (13) and supporting ring have to be fitted in the outer mowing element. If this element is replaced,
these parts need to be moved over to the new unit.
- Apply grease (Molykote BR 2 Plus) to the ring (8) as well as to the threaded part of the connecting rod (3) and nut (7).
Fit the nut on the rod.
- Tighten the nut (7). Torque: 950Nm (95 kgm). This torque is realised by extending your wrench with a 150 cm long pipe (fig. A-4) and by then applying a force of 635 N (63,5 kg). When fitting the securing plate the nut should be tightened and is not allowed to be unscrewed.
Only for SPLENDIMO 360 T mower:
- Fit the additional coupling bar (diagram A-2) as follows:
• Mount the coupling bar complete with support arm (C)
and spacer (D).
• Fit the bolts (B) and spring washers (half-fastened).

B OPTIONAL EXTRAS
Skids
Skids fitted underneath the cutter bar ensure that the SPLENDIMO mower follows the ground contours more easily. Due to the streamlined shape of the skids, the mower does not dig into the ground in case of unevenness while at the same time soil is prevented from building up underneath the discs. In addition to this, the skids make sure that the ground pressure is distributed more evenly across the width of the cutter bar.
Wear plates
To avoid excessive wear and tear of the skids as a result of abrasion, the SPLENDIMO mower can be equipped with wear plates that are fitted underneath the skids. These wear plates can be replaced easily and at low cost. They come in a thickness of 4 or 8 mm.
Topping skids
By fitting so-called ‘topping skids’ underneath the skids, the cutter bar of the SPLENDIMO mower is enabled to mow
somewhat higher above field level in rough conditions. In that case, the mowing height also increases by approx. 7 cm so that the knives do not dig into the ground. This may be
important when mowing fallow lands or in nature landscapes. The turf is spared because the knives do not dig into the ground. The cutter bar, too, is spared since it is not hit by stones, branches etc..
Swath board kit
To reduce swath width, a special kit can be fitted to the SPLENDIMO mower so that no grass is run on by the tractor
wheels.
Stabilisation chain
Correct height of the hydraulic linkage is essential to the machine’s freedom of movement, so it should be maintained after initial adjustment. For tractors that do not have a consistent linkage height, a stabilisation chain can be supplied to steady the lower linkage position.
