Krone KW 7.92 / 8 Rotary Tedder

KW 7.92 • KW 8.82 • KW 10.02 • KW 11.22

Eight/ten-rotor machines with three-point linkage attachment

• 7.90 m to 11.00 m work widths
• Small and mid-sized rotor diameters for identically spaced rotors in any situation
• Damper braces with Eladur spring elements for convenient transport without shockloading
• Fold-in end rotors reduce the transport height

KW 7.92, KW 8.82, KW 10.02 and KW 11.22 are mounted to the tractor’s three-point linkage. Dispensing with the transport running gear, the machine is marketed at a very competitive price and still offers a high level of base specification including central border spreading control. One single-acting spool is all that’s needed to operate the KW 7.92. With all rotors spaced at identical distances, the machine produces a uniform spread pattern.

Nobody can afford to waste their crop. KRONE eight-rotor rotary tedders feature a manual border spreading system as standard. A hydraulic border spreading system is standard specification on the KW 10.02 and KW 11.22. The system keeps your crop exactly where it should be - on your field.

The rotors are folded hydraulically. The outer rotors swing in to reduce the machine’s transport height.

The driveline

Permanently lubricated rotor gearboxes: The enclosed liquid-grease lubricated gearboxes that drive the rotors are absolutely maintenance-free. Permanent lubrication gives peace of mind and increases the machine’s longevity. The chunky box section chassis absorbs all shock loads on the frame.

The dependable system

When it comes to preparing wilted silage and hay, KRONE is the manufacturer that offers a large and extensive range of high-quality and dependable rotary tedders. These machines not only deliver high-quality work and feature a high level of standard specification but also boast a host of innovative features including maintenance-free OctoLink finger clutches and liquid-grease lubricated gearboxes to drive the rotors. OctoLink is our extremely hardwearing clutch, which forms a frictional connection at all times and yet requires no attention at all. Some of its eight fingers are always in mesh, even when the rotors are folded through 180 degrees.

The rotors

The small rotors produce quality forage KW 7.92 (7.90 m, 8 rotors), KW 8.82 (8.80 m, 8 rotors), KW 10.02 (10,00 m, 10 rotors) and KW 11.22 (10.95 m, 10 rotors) are forage specialists which stand out for their robust build that has perfectly proven itself in heavy crops. Small diameter rotors with four or six tine arms each deliver an effective job.

Uniform distribution of the material

The tine arms mesh as they rotate, spreading the material uniformly across the working width to ensure the best possible wilt for quality forage. The smaller the rotor diameter, the larger the orbital overlap.

Clean forage, uniform spread

Quality requires us to start with the basics. This is how we achieve high standards. The rotors on the KRONE rotary tedders are the ideal equipment to produce quality forage for on-farm use. These rotors spin for you – in hay and silage. The two 9.5 mm (0.4") legs that form one pair of tines vary in length to provide the special KRONE combing effect for optimum treatment and cleanest forage. Five coils on each Super C steel spring tine give flexibility and strength. Special stops on the ends of the tube-section tine holders ensure no tines are lost.

Adjusting to needs

The hex-head bolt on a separate eccentric plate instantly locks the double tine in one of three positions to provide more or less vigorous action and achieve optimum results in all conditions.

High performer in arduous conditions

Heavy-duty tine arms (38 mm x 4 mm (1.5" x 0.2") tube steel) and a special ring attachment system combine to provide dependable performance in tough and permanent operation. KRONE technology gives you true peace of mind in the most difficult conditions.

Warranting top quality forage

• Central border spreading control spreads the crop away from the boundary for easier harvesting.
• The angle of throw is adjusted without tools.
• The castering wheels on the rotors run in close vicinity of the tines to provide accurate control

Tedding at a steep angle, turning at a shallow angle

You can adjust the spreading angle between 13° and 19° by refitting a pin in a hole pattern on the wheel arms. No tool required. The steep spreading angle is perfect for tedding, producing intensively conditioned forage. With its gentler conditioning action, the shallow angle is better when making the headland turn.

The headstock

The headstock rests on a separate stand, which folds down to support the machine. The driveshaft is stored in a separate holder on the headstock. The stand locks in place automatically when not in use.

Dampers for an enhanced ride quality

The internal compression spring (1) prevents underrunning when working downhill and the adjustable brake (2) prevents bouncing. The large machines of a 7.80 m (25'7") plus work width have additional Eladur spring elements (3), which enhance rides on public roads and bumpy dirt roads.

Hydraulic and convenient: Most three-point hitch models require only one double acting spool. Spring-loaded hydraulic rams ensure smooth lowering on the slope.
