Product Description

GKB Combinator | CB Series | Working Width 48", 63", 79" & 95" | 35-110 HP | For Tractors

DESCRIPTION

The GKB Combinator is the ultimate tool for removal of unwanted turf and fraise (fraze) mowing. This machine has the capability to remove up to 2″ of unwanted material in a single pass. This allows you to run a clean and efficient operation, totally removing the organic matter and leaving a clean and level surface. This is the only step needed before re-seeding or laying sod. 

In addition to complete turf removal, the GKB Combinator can be adjusted fraise mowing! Fraise (Fraze) mowing is a thatch management practice founded in the Netherlands (home of GKB Machines) in the mid 1990s. The Combinator was designed, built and perfected by the family that created the first ever fraise mower. 

The solid steel rotor on the Combinator is driven by a high speed belt system and the working depth can easily be adjusted without tools. The rollers are connected to a pendle system that allows you to adjust the front and rear rollers simultaneously. The Combinator’s elevator belt folds flat for transportation!
