Grassland specialists Kuhn has extended its Gyrorake offering with the addition of the GA 8731+ and GA 9531+ models.
Like the smaller Rubin 10 models offered up to seven metres wide, the new Rubin 10/1000 offers a symmetrical disc arrangement for fuel-efficient operation without side draft.
Up front, hitching to the tractor uses a ball coupling or drawbar eye. Ease of attachment and removal is aided with the addition of a hydraulic support stand.
The two rows of 645mm diameter serrated concave discs allow a thorough incorporation across the full surface width from a soil depth of only seven centimetres. A 14cm spacing between the discs helps ensures blockage-free work, even when operating in stubbles with high volumes of organic matter.
Each disc is equipped with a coil spring overload protection with damped kickback, helping to reduce shock loadings on the main implement frame.
Clever design details across the working sections feature a pendulum type suspension to ensure optimal following of the field contour. On very uneven terrain, or when working on slopes, the optional iQ-Contour pendulum compensation guarantees optimum surface adaptation.
In addition, the hydraulic depth adjustment makes it possible to respond to changing conditions and the working depth can be changed on the move.
For transport between job sites, the machine is folded from the cab. The rear rollers patented folding system ensures a three-metre transport and a height of only four metres.
