DESIGNATED USE OF THE MACHINE The GF 6401 T Gyrotedder must only be used for the work for which it has been designed : spreading and turning pre-mowed fodder and straw. When fitted with a reduction gearbox, the GF 6401 T can also be used for forming small night swaths in order to reduce the amount of humidity getting into the crop overnight.
Page 5 GENERAL SAFETY RECOMMENDATIONS Before operating the machine, always ensure that tractor and machine are in accordance with work safety and road traffic regulations. BASIC PRINCIPLES 1. In addition to the recomendations given in this manual, legislation on work safety and accident prevention must also be respected.
Page 6 17. Never leave the tractor seat while the machine is operating. 18. Drive speed must be adapted to ground conditions as well as to roads and paths. Always avoid abrupt changes of direction. 19. Precision steering, tractor adherence, road holding and efficient braking are influenced by the type of implement, weight, ballast of front axle, ground or road conditions.
Page 7 ATTACHMENT 1. When attaching or removing the machine from the tractor, position hydraulic lift control lever in such a way that it cannot be set off accidentally. 2. When attaching the machine to the tractor linkage, ensure that diameter of the link pins corresponds to the diameter of the ball joints.
Page 8 HYDRAULIC SYSTEM 1. Beware ! The hydraulic circuit is under pressure (maximum working pressure : 200 bars/2900 psi). 2. When fitting hydraulic motors or cylinders, ensure that connections have been made correctly, as per manufacturer’s instructions. 3. Before connecting hoses to the tractor hydraulics, ensure that tractor and machine circuits are not under pressure.
Page 9 8. Spare parts used must be in accordance with specifications and standards as defined by the manufacturer. Use only genuine KUHN parts ! 9. Before any electric welding is carried out on tractor or attached machine, disconnect generator and battery terminals.

A - MACHINES SHIPPED IN CRATES To facilitate shipping, the GF 6401 T is packed in a wooden crate with some disassembled parts. Also, on certain machines, the roll pins (L) (photo A) have not been driven in so that the side wings can be folded even further towards the inside, thus reducing the shipping width of these machines.
Page 13 - 11 -...
Page 14 There are two types of tines : a) Tines for rotors which turn to the left (counter clockwise) : the “KUHN” marking is found on the longest finger (see figure 3).
