Kuhn goes mounted with latest GA twin-rotor rake
Kuhn’s 7.4m close-coupled mounted twin rotor rake © Kuhn A new grass rake built to have the capacity of a twin-rotor trailed machine and the handy manoeuvrability of a mounted unit has joined the Kuhn range for gathering spread grass into a single swath.
The 7.4m GA 7631 P has hydraulic working width adjustment as standard, enabling users to set up swaths from 1.3m to 2.2m wide to suit the forage harvester, wagon or baler working in its wake.

And when moving from yard to field (or field to field) by road, all tine arms can remain in place with the rotors brought up to a vertical position.
Sam Alford, Kuhn’s grassland product specialist, reckons the new model would suit smaller- to medium-sized farms where a single-rotor rake has reached its output limit or where tight field access prohibits a trailed version.
Components well-established on other Kuhn rakes are used, including the Masterdrive GII maintenance-free gearbox, and the tine arm bearings have lengthy greasing intervals of 200 hours.
To minimise soil contamination in the swath, the rake’s rotors have 3D articulation in all directions to follow ground contours accurately and collect all the crop cleanly.
Working height adjustment can be hydraulic or manual, and all other movements – such as individual rotor lift, folding and unfolding – can be carried out from the tractor cab.
Power requirement is modest, but a tractor of decent size – about 140hp – is advisable to support the machine’s 1.5t mass with stability.
