    SAFETY The above symbol is used throughout this manual every time recommendations are made concerning your safety, the safety of others, or the good operation of the machine. These recommendations must be made known to all machine operators. DESIGNATED USE OF THE MACHINE Mower Conditioners must only be used for the work which they have been designed : mowing on the ground of hay fields, grass silage fields and improved pastures for the purpose of harvesting fodder for feeding livestock.
  • Page 5 1. In addition to the recommendations given in this manual, legislation on work safety and accident prevention must also be respected. 2. Advice is indicated on the machine, specifying safety recommendations in order to prevent accidents. 3. Before travelling on public roads, the operator must ensure that the machine conforms to road traffic regulations. 4.
  • Page 6 20. Be particularly cautious when turning corners, paying attention to machine overhang, length, height and weight. 21. Before operating the machine, ensure that all safety guards are firmly in place and in good condition. If worn or damaged, replace immediately. 22.
  • Page 7 5. If a primary PTO shaft is equipped with a slip clutch or a free wheel, these must be fitted on the machine PTO. 6. Ensure that PTO shaft is always correctly fitted and locked into place. 7. Make sure guards are correctly in place and secured with the safety chains provided. 8.
  • Page 8 4. Each time before using the mower conditioner, inspect condition of cutting elements (knives, discs). Replace any missing, worn or damaged cutting elements immediately. Use only genuine KUHN spare parts. 5. To avoid creating dangerous out of balance forces, always replace missing, damaged or worn knives in pairs.
  • Page 9 9. Crushing and shearing zones which could cause serious bodily injury when changing the machine from transport to work position and vice versa may exist. To prevent possible injury, be extra careful when maneuvering and ensure that everyone is at a safe distance away from the machine.

  • Page 28: Transport

    Never operate the PTO shafts at too great an angle (X = 25° maximum) (fig. M). TRANSPORT To transport the machine on public roads or from one field to another, proceed as follows : - Make sure discs and rotor have come to a complete stop. - Lift the machine using the tractor 3-point linkage - Pressurize the hydraulic cylinders to lift the cutting conditioning unit into its vertical position.

  • Page 29: Working Position

    WORKING POSITION AND ADJUSTMENTS 1) Pressurize hydraulic cylinders and pull cord (A) to free lock (I) (photo 21). 2) Lower cutting conditioning unit into the work posi- tion by releasing the hydraulic pressure. As soon as the cutting conditioning unit starts to pivot, release pressure on the cord (A).
  • Page 30 Adjustment of chassis height from the ground : : set lower link height so that roll pin (F) is exactly centered in its aperture (H) (photo 23). This gives height E = 400 mm approximately (photo 22), which corresponds to a cutting height of 30 mm.

  • Page 31: Adjustments

    ADJUSTMENTS Cutting height Maximum cutting height (80 mm / 3") (fig. 26) is achieved when the discs are parallel to the ground. Adjustment of cutting height is achieved by altering the cutterbar tilt angle. This is effected by varying top link length (P) (photo 25) until desired cutting height is achieved.

  • Page 35: Operating The Mower Conditioner

    OPERATING THE MOWER CONDITIONER GENERAL Before engaging the machine into the grass, lower the cutting conditioning unit to the ground and bring the PTO shaft up to its nominal speed Do not allow the PTO to drop to too low a speed as this would reduce cutting quality and cause rotor plugging. If this should occur, immediately disconnect the PTO, stop the tractor engine and remove the ignition key.

When mowing embankments, make sure there is (see photo 41) between cutting conditioning unit (G) and frame (E). ADVERSE FIELD CONDITIONS Extra care and precautions should be taken in rough or debris-ridden fields. The following adjustments should be made to the mower conditioner in these conditions to minimize the possibility of foreign objects being deflected by the cutting knives.

    SAFETY CLUTCH WITH SHEAR BOLT If during work the conditioning rotor stops rotating but the discs are still driven, disengage the P.T.O., stop the tractor engine, remove ignition key and wait for all rotating parts to stop before leaving the tractor. Remove the 2 broken parts of the shear bolt and replace it by a new bolt (V) (part no.
  • Page 38 CHECKING OIL IN THE CUTTERBAR (fig. 43 and 43 A) Cutterbar oil level can be checked by measuring oil level through both filler plugs (21) when the cutterbar is perfectly horizontal lengthways and crosswise (X and Use a spirit level to ascertain that this is the case. Correct oil level is 6 to 7 mm (1/4") at both filler plugs (21) (fig.
  • Page 39 CHANGING GEARBOX OIL Check gearbox oil level daily. Top up with SAE 80 W EP (GL4) oil if necessary by filling up through plug (B) (photo 44). Check oil level through plug (C) (photo 44) when the cutterbar is horizontal to the ground. Oil level is correct when the oil reaches the edge of the hole.
  • Page 40 P.T.O. SHAFTS Lubricate all PTO shafts with SHELL Multi-Purpose grease NLGI grade 2 at the hourly intervals indicated in fig. opposite. To reach the U-joint grease fitting (rotor side) of the secondary PTO shaft, disconnect the PTO shaft on the gearcase side and tilt down the PTO shaft to gain access to the lubricating hole located in the protection cover (photo 46).

  • Page 41: Maintenance

    MAINTENANCE BELT Belt must be properly tensioned at all times to prevent excessive slipping and flopping. A loose belt will cause poor cutting and premature failures. Check powerband tension as follows : - Remove belt guard. - Unlock counter-nut (E) (photo 47) and loosen belt (C) (photo 48).
