Kuhn Rotary Tedder – other models from Saverne, Alsace: GF tedders from the compact GF 222 to the wide GF 17002, PTO-driven grassland machinery
Kuhn is based in Saverne in Alsace and ranks among the leading makers of grassland machinery. This collective page lists rotary tedders of the GF range outside the independently maintained main ranges, which fluff up mown grass or hay and turn it for faster drying; the number in the type designation grows with the working width and the number of rotors of the respective machine.

The register lists here 47 versions, from the compact GF 222 with few rotors to the wide GF 17002 with correspondingly more rotors, complemented by MH and T variants for different mounting and transport versions.
Rotary tedders such as the GF range are basic equipment in forage harvesting: after mowing they ensure grass or hay is evenly aerated and dries faster before being raked into swaths and harvested; the range of working widths covers both smaller farms and large-scale grassland operations.
Such tedders are driven from the tractor's power take-off, usually at 540 rpm on smaller versions and more often at 1,000 rpm on wider models; they are mounted on the three-point linkage to ISO 730, with the category depending on the tractor's power class and the tedder's weight. A slip clutch or freewheel in the drive-shaft line protects the rotor gearbox from overload when a rotor strikes an obstacle.
On used examples, the condition of the tine arms and the tines themselves for wear or bending, the condition of the rotor gearbox and its oil level, the condition of the PTO shaft and its guard, and, on foldable versions, the function of the transport hydraulics all matter; spare parts run through the Kuhn dealer network.
