Page 4: Safety
DESIGNATED USE OF THE MACHINE The HR 5002 DR / 5002 DR - S / 6002 DR / 6002 DR - S Power Harrows must only be used for the work for which they have been designed : secondary cultivation and seedbed preparation. - 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 recommendations given in this manual, legislation on work safety and accident prevention must also be respected.
- Page 6 17. Drive speed must be adapted to ground conditions as well as roads and paths. Always avoid abrupt changes of direction. 18. 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. It is therefore of utmost importance to be cautious in every given situation.
- Page 7 POWER TAKE-OFF 1. Only use PTO shaft supplied with the machine or recommended by the manufacturer. 2. PTO guards must always be in place and in good condition. 3. Check for correct PTO overlap when at work and in transport. 4.
- Page 8 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.
- Page 9 SPECIAL SAFETY RECOMMENDATIONS Total transport height of the machine measured from the ground must not exceed 4 m (maximum height allowed by the highway code). ROAD TRANSPORT Dimensions Depending upon the machine’s dimensions, the user should check with the relevant authority that it can be transported legally on public roads.

SIGNALLING ELEMENTS Fix the support (1) of the preassembled signalling panels on the frame of the machine with 4 hexagonal screws (2) (M 10 x 100), 4 self-locking nuts (M 10) and 2 flat iron bars (3) (photo 1). Fix the wiring harness on the machine frame with the supplied clamp collars. -
Page 14: Fitting To The Tractor
DR must always rest on the soil with the 2 half-harrows unfolded (photo 3). The HR 5002 DR - 6002 DR can be attached to all tractors equipped with a Cat. 3 three-point linkage. The independently floating lower links (C) facilitate this operation. -
Page 15: Primary Pto Drive Shaft
P.T.O. DRIVE SHAFT Make sure the rotary harrow is resting on the ground and is maintained in a stable position with the rollers. Install the PTO shaft making sure that the clamp yoke is on the machine end. Tighten both M 16 bolts to 22 daNm / 160 ft.lbs. - Page 16 To avoid accidents which could be serious, make sure that the guards are always correctly in place and secured with the safety chains. The safety chain on the machine side must be attached in the hole pro- vided in the metal guard of the cen- tral gearbox (see figure 6).

Page 17: Walterscheid Cut Out Clutch
WALTERSCHEID CAM TYPE SAFETY CLUTCH Each side bevel gearbox is fitted with a Walterscheid cam type safety clutch as standard. These adjustable safety clutches are based on the principle of disengaging cams. They are activated when there is an overload and disengage the drive of the machine. They are factory adjusted to a maximum tractor power of 206 kW (280 DIN hp) and for a PTO speed (rotational frequency) of 1000 rpm (min After a torque cut-out, it is important to disengage the PTO drive and lift the machine out of work. -
Page 18: Rotor Speed (Rotational Frequency)
ROTOR SPEED (ROTATIONAL FREQUENCY) The HR 5002 DR / 6002 DR / 5002 DR - S / 6002 DR - S must only be driven at a PTO speed (rotational frequency) of 1000 rpm (min ). All gearboxes are factory fitted with a rear PTO shaft which rotates at the same speed (rotational frequency) as the tractor PTO shaft. -
Page 19: Rollers
ROLLERS According to the user’s choice, the rotary power harrows can be equipped with : - either 2 maxicrumbler rollers (with welded tubes) (only for HR 6002 DR / 6002 DR - S), - either 2 packer rollers (rows of continuous studs welded on a cylinder), - or 2 maxipacker rollers (rows of discontinuous studs welded on a large diameter cylinder). - Page 20 2) PACKER ROLLER HR 5002 DR / 5002 DR - S : Code 123 6720, quantity 2 HR 6002 DR / 6002 DR - S : Code 123 6730, quantity 2 This roller is particularly intended for use in wet or sticky soils. Efficient packing, proper levelling and good crumbling are achieved.
- Page 21 3) MAXIPACKER ROLLER HR 5002 DR / 5002 DR - S : Code 123 8410, quantity 2 HR 6002 DR / 6002 DR - S : Code 123 8420, quantity 2 This roller is suitable for all soil types and especially humid and sticky soils. It provides an efficient ground packing, a good levelling and crumbling.
- Page 22 b) Adjusting the scraper plates - The hard coated thick scraper plates have been factory pre-set on a reference roller. Therefore, they are nearly in the correct working position after mounting the scraper bar (paragraph a, page 19). When the machine is attached to the tractor, always check that the roller can rotate freely.

Page 23: Side Deflectors
SIDE DEFLECTORS Anti-ridging plate (G) fitted to side deflectors (L) mounted at either side of the machine are adjustable in height and forward position. a) Height adjustment : Three positions exist de- pending on working depths and blade wear. To adjust the side deflectors (L), remove the 6 bolts (F), place the plate (G) to its new position and re- tighten the bolts (F) (torque 10 daNm / 75 ft.lbs) (photo 12). -
Page 24: Soil Loosening Share
FRONT SOIL LOOSENING SHARE A soil loosening share (S) fixed at the front of the machine lifts the non worked strips of land between both harrow halves. It is adjustable in height (connecting pin n° 1) to match the machine’s working depth. The second connecting pin (2), at rest (photo 13), gives the opportunity to raise the soil loosening share to increase the ground clearance during transport. -
