Kuhn HRB 122 orchard and vineyard power harrows are exceptional due to their dimensions, durability, and standard equipment. The HRB 102 Series has working widths that range from 4’ to 10’1” and can be used with a tractor of up to 140 horsepower, depending on the power harrow used. No compromises have been made just like models with larger working widths. With seedbed preparation, the HRB 102 power harrows allow for small clods on top, fine soil around the seed, in-depth packing and exact leveling to ensure even germination. With no chance for weeds, spring or summer tillage using power harrows allows an environmentally friendly alternative instead of chemical control.
With their low height, rounded frame edges combined with narrow widths, the HRB 102 Series is the ideal tool for specialized work. The strong rotor drivetrain is fully protected by a rigid, central gearbox. A rear PTO is fitted as standard on all machines to easily adapt secondary rear implements required for vineyard and orchard work.
Compact & Robust Housing
The section, blade teeth and blade holders form a compact and robust assembly. The small distance between the section and the top of the blade holders prevent stones from getting jammed. Moreover, the soil flow is directed down toward the blades.
A large-diameter, maintenance-free Crumbler roller enables good soil framing and an efficient working depth adjustment. The HRB 202 can also be equipped with a packer roller.
With their narrow width, these machines are easily and safely transported from one field to another.
Maintenance-Free, High-Strength Gearbox
This durable cast-iron gearbox with rear PTO enables flawless rotor drive. The gearbox is six mm thick on the HRB 122, 152 and 182 and 8 mm thick on the HRB 202, made from fine grain, high-tensile steel. It contains semiliquid grease, which ensures lubrication of pinions and gears all through their service life. O-rings and lip joints ensure sealing for a longer service life.
