GKB Machines

GKB Machines are Dutch built turf renovation and maintenance machinery, distributed in New Zealand by TrenchIt. They cover the full maintenance cycle on natural grass — aeration, scarifying, seeding, sand dressing and fraise mowing — and the cleaning and decompaction work that keeps synthetic pitches playable.

Most models come in several working widths. Tell us your surface, your tractor and the job, and we will point you at the right size.
