The unique property of the Lely Centerliner is that each of the 2 spinner discs – with 4 spoons each – covers the whole spreading width. The spreading patterns overlap each other as a result.
On most twin-disc spreaders, the spinner discs rotate from centre to outside (seen from the rear). Each disc produces a half spreading pattern. These two patterns are then laid against each other in the middle behind the tractor. Only a very accurate dose rate setting, that has to be repeated when switching to another type of fertiliser, can prevent stripes behind the middle of the tractor due to a wrong overlap. The Centerliner does not have this problem, because the 2 spreading patterns overlap each other completely over the entire spreading width. This is in fact a full, double overlap!
With most twin-disc spreaders the spreading pattern slopes steeply towards the sides. The adjoining working bout has to link up with previous bout, which means that even minor driving faults will easily lead to stripes in the crops. The Centerliner spreads up to the previous tramline, which means this problem doesn’t apply. That’s why a driving error of 1 meter or more is a lot less critical and doesn’t disturb the combined spreading pattern. So not only does the Centerliner provide a double overlap per working pass, but it does the same with each consecutive bout. Therefore we can easily state that the TULIP Centerliner provides 2x a double overlap.
Spoons and bowls:
The special shape of the spoons is the result of many tests. The suction power of the spoons together with the forced dose result in a constant and even supply of fertilizer. The spoons of the left spinner disc are positioned at a 45° angle compared to the spoons of the right disc. This results in no collisions between fertiliser coming from different discs. The result is an even and synchronised dose. The bowls are very close to the spinner discs for an accurate spreading pattern even on slopes. The drop point is in the centre so the fertiliser gently accelerates along the vanes instead of getting smashed by it.
The dose rate may vary under the influence of pellet size and humidity. To ensure an accurate dose rate, the calibration bowl can be used to quickly check flow rates prior to spreading.
Quadruple spreading pattern:
The quadruple spreading pattern leads to a very low variation coefficient. In practice stripes are detected very rarely. Every square meter in the field receives 16 small doses of fertiliser. As a result the machine is very forgiving for user errors. This makes setting up the machine easier for you.

- Walterscheid PTO shaft with slip clutch (1 3/8” – 6 splines tractor side), Telespace version for SXe
- 1 Set of change gears 23/12
- 2 Mesh wire sieves
- Safety and lighting set LED
- Large stainless steel tractor protection sheets
- Two spinner discs which rotate to the inside. Exact distribution through quadruple overlapping.
- Adjusting spreading width by means of changing gears: a perfect adaptation to different types of fertiliser, exact adjustment of the working width, easily changeable, working width from 6 up to 36 m.
- Hydraulic tilt ram: when headland spreading is required the Centerliner spreader can be tilted. This reduces the spreading pattern on one border side, one pass creates the headland spreading.
- EASYtronic (for the SXe version): this compact terminal with touch screen and color display is linked via CANbus with the job computer on the machine. In addition to the EASYtronic E specifications, this combination regulates automatically the dosage, tramlines, etc. These values are shown on the screen. Optional is the EASYtronic+ where everything operates via Isobus.
- Telespace PTO shaft (for the SXe version): special telescoping PTO shaft which can be extended by 30 cm before attaching to the tractor. This gives a free access, so other connections can be made.
Further explanation accessories
- Centraside: headland spreading kit to obtain a sharply limited spreading pattern at the right side of the spreader. At the left side of the spreader the spreading pattern fades off to the next working passage. The Centraside is available in a manual and a hydraulic version.
- Disc valve: mechanical or hydraulic device for closing the left spreader bowl when using a Centraside headland spreading set.
- With the hydraulic Centraside and disc valve it is possible to switch over from full field operations to headland spreading (and vice versa) without leaving the tractor.
- Connector cable: uses the pulse signal of the tractor’s forward speed sensor.
- Magnetic sensor: measures the forward speed via magnets mounted on tractor wheel. This set can also be used for other machines which require forward speed measuring.
- GPS speed measuring sensor: a GPS sensor is used for measuring the speed instead of the wheel sensor kit.
- Advantages: a compact kit, easy to mount and to use, no special construction is required.
