1 INTRODUCTION
The LELY SPLENDIMO TC mowerconditioner is used for mowing grass lands. Mowing on slopes up to approx. 30° up and 30° down is within the machine’s capability.
The machine is built up of a cutter bar and a conditioner unit.
Depending upon the application, the cutter bar is fitted with type A or type B discs (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 is driven from the top. Different cutting units are used for the different directions of rotation called “S” or “N” (fig. A-2). 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 TC mower with “S” model discs can be fitted in a different configuration (depending upon the combination of disc/ knife).
The conditioner unit comprises of a rotor fitted with fingers made of an impact-resistant synthetic material, an aluminium hood with swathboards as well as a crop inlet plate for adjustment of conditioning intensity.
The conditioner unit operates over almost the full cutting width. Crop treatment is such that patches of the waxy layer on the stem are removed and that thick stems are broken. The crop is slightly turned and laid down behind the machine in an airy, narrow swath. There is a minimum contact between the crop and the moist field and there is no need to drive on mown crops.
The SPLENDIMO TC 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 double linkage pins (category II) giving two linkage possibilities (fig. 3) and allowing adjust­ment of the offset position of the machine behind the tractor.
- Choose position for the SPLENDIMO 240 TC mower and position for the SPLENDIMO 280 TC mower. In this way, the centre of the swath is positioned underneath the centre of the tractor in the next pass. Always use position when mowing down a descending slope so that you can operate as far from the side as possible.
- 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. 60 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 machine 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.

3 TRANSPORT
The SPLENDIMO TC mower can be transported on the tractor’s 3-point hitch.
- 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.
• 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.
The machine is now ready for transport.
4 MACHINE ADJUSTMENTS
- Pull up the locking hook of the hydraulic ram and lower the machine 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 60 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.
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. 6).

Page 13
4.2 Intensity of conditioning
The intensity of conditioning can be adjusted by means of the conditioner’s crop inlet plate and through the rotor speed.
- Adjust the crop inlet plate. Position (A, fig. 7) ensures the highest intensity of conditioning, whereas it is lowest when the crop inlet plate is adjusted to the (B) position. There is one intermediate position. Lock the crop inlet plate on both sides of the conditioner hood.
- Place the machine on a level floor and lift the headstock up to at least working height in order to prevent oil from flowing out of the gearbox after removal of the cover. Fit the correct gear combination (fig. 8) to obtain the required rotor speed.
The highest intensity of conditioning is obtained by adjusting the crop inlet plate in the (A, fig. 7) position, combined with the highest rotor speed.
If the lowest rotor speed is combined with the (B) position of the crop inlet plate, the crop is hardly conditioned.
4.3
Swath width
Swath width of the SPLENDIMO 240 TC mower is adjustable from 0,8 up to 1,6 m - for the 280 TC model it can be varied between 1,0 and 1,8 m.
- Use the adjusting device (fig. 9) to obtain the required opening of the swath-board. Then lock the adjusting device.

5 OPERATING THE MACHINE
• Always operate with the safety cover folded down. Secure it firmly in the clamp block (fig. 10).
• 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 machine you only need to retract the hydraulic ram.
The machine will first be raised approx. 10° (fig. 10), after which it is lifted from the ground. The machine then folds up further until the locking hook hits the cam on the piston rod (fig. 12). This allows quick turning on headlands.
For total folding of the machine, the locking hook needs to be pulled up.
Mind the following directions when working with the SPLENDIMO TC mower.
- Lower the machine by means of the hydraulic ram until it is just above crop level.
Engage the PTO shaft at the lowest possible engine speed.
- Then rev up PTO speed up to 540 r.p.m. which is the maximum speed allowed during work.
- Lower the machine 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. 8 km/h. A lower speed may affect crop flow­through across the cutter bar. Speeds higher than 8 km/h may decrease the conditioning action.
- Make sure that the PTO speed of 540 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 around the discs.
- First, lift the machine from the crop and then reduce your PTO speed immediately.

Should the machine hit an obstacle during mowing, it can move backward thanks to the extension of the breakback device (fig. 13).
- After extension of the breakback device: drive backwards a few meters until the breakback device has locked back into position.
The conditioner’s rotor is protected against overload by a shearbolt facility.
- Replace a broken shearbolt by a bolt M8x35-8.8 (fig. 14).

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 (fig.
25).
• Sense of rotation “S” combined with a drive disc type
“BLX”: use 100 mm mower knives.
• Sense of rotation “N” combined with a drive disc type “N”: use 120 mm mower knives.
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.
- Use new nuts and tighten them with a torque of 50-60 Nm (5 - 6 kgm).
7.5
Change 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. 26) with 1.7 l transmission oil (GX85W-140).
- Fill the gearbox B (fig. 27) with 0.85 l transmission oil (GX85W-140).
- Keep the cutter bar in a vertical position and fill the drive element C (fig. 27) with a carefully measured quantiry of
0.45 l transmission oil (GX85W-140).
An incorrect oil level may lead to overheating and unrepairable damage of the drive 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.
