Do your natural grass sports pitches not meet your requirements? Are you confronted with weed grasses, a buildup of black layer and organic matter or is the sports pitch not level? Do you want to keep your sports pitches in excellent condition? The Combinator provides you the ultimate solution.

In the late 1990s, the GKB Group and the Council of Rotterdam developed the predecessor of the Combinator. The method of removing the surface layer is still in worldwide practice today.

Today, subjects such as chemical free weed control, the removal of infill and sustainability are actual. Together with the Combinator you can respond appropriately to current needs and requirements.

How it works...

Fraise mowing top layer

There can be various types of placed on the rotor, however for fraise mowing the machine uses “L-shaped” fraise chisels to fraise mow the top layer of the sports field's natural grass. With special hybrid chisels, you can remove the top layer with the natural grass from your hybrid sports field. The artificial grass fiber remains in place.


You can also use the Combinator for scarifying by placing scarifying blades of various widths at the desired distance. The extracted material is placed on the conveyor belt and transported away. If you use the VStrong you can also scarify without a conveyor belt, directly redistributing nutritious soil back onto the turf.

The optional ‘hold down plate’ also allows you to scarify un-stitched hybrid fields. The hold down plate ensures that the artificial grass stays in place, while removing the unwanted organic material.

Heavy-duty and ingenious

The working depth of the Combinator can be easily and precisely adjusted with the unique pendulum system. Due to the solid build quality, the machine can also take a beating. In short, the Combinator is everything you need for fraise mowing and scarifying the top layer of your sports field.
