Features
SUPERIOR SOIL FINISHING
Side Deflectors
The shape of the side deflectors provides efficient ground guidance and channeling to ensure a good finish between passes.
Depth Control
A large-diameter, maintenance-free Crumbler roller enables good soil framing and efficient working depth adjustment. The HRB 202, 252 D and 302 D power harrows can also be equipped with a Packer roller.
HIGH-STRENGTH & SIMPLE DESIGN
Hitch
The hitch is made from a shaped and welded triangular steel plate. This helps ensure longevity in all soils and conditions.
Compact and Durable Housing
The section, blade teeth and blade holders form a compact and durable assembly. The small distance between the section and the top of the blade holders prevents stones from getting jammed. Moreover, the soil flow is directed down toward the blades.
Driveline
The HRB 122, 152, 182 and 202 come standard with shear bolt protection for the driveline. A friction slip clutch is standard with the HRB 252 D and 302 D, with an optional cam clutch. All KUHN power harrows feature a rear PTO output shaft.
Gearbox
The HRB 122, 152, 182 and 202 feature a single-speed gearbox. The interchangeable Duplex gears on the HRB 252 D and 302 D allow different rotor speeds for excellent mixing whether the soil is hard or crumbly. These models also offer additional gear sets for an even wider range of available rotor speeds.

Simple Design
