The Tulip Disc Harrow Multidisc comes with discs of Ø 510 mm and is designed for working depths ranging from 4 to 10 cm. The Multidisc XL versions feature Ø 560 mm discs which are suitable to work deeper. The XL has more clearance between the 2 disc rows and is thus better suited for fields with lots of crop remains like maize and sunflower. The XXL has discs Ø 610 mm and larger gang spacing for better flow. The XXL legs are set lenghtwise to make them sturdy and resistant to very harsh conditions.

The Tulip Disc Harrow roller has many settings and a floating system. This system controls the working depth of the machine.

The Tulip Disc Harrow Multidisc are available in mounted rigid, mounted folding H, and semi-trailed folding HT models ranging from 1,8 up to 12 meters wide. Folding Multidiscs can be stocked in folded position. Simple and compact!

The unique property of the 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.
1. 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!

2. 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. Hence 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.

The Centronic II GPS electronic control system adjusts the outputfrom the Centerliner to any change of the tractor forward speed. This way the amount of fertiliser spread per hectare stays constant, independent from tractor speed. From the tractor cabin, the rate can be altered quickly during driving. The screen displays among others: forward speed, desired kg/ha, shutter position, spinner disc rpm, distance driven and worked area.

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 fertilizer 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 inclines. The drop point is in the centre so the fertilizer gently accelerates along the vanes instead of getting smashed by it.

The quadruple spreading pattern leads to a very low variation coefficient. In practise 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.
