Whatever the conditions, the cultivations must be of high quality. We develop soil preparation tools with special attention to ensuring quality work while being very versatile. Known for their robustness, reliability, safety and durability, KUHN power harrows are synonymous with low operating costs and reduced maintenance operations. HRB 122-152-182-202 power harrows are efficient in mechanical weeding in-between rows (vineyards / orchards) incorporating plant material into the soil and improving the soil structure.

Rely on the robustness of KUHN power harrows

HRB 122-152-182 power harrows have a high-tensile steel trough and a lifetime lubrication of the sprockets and bearings with semi-fluid grease. Sealing is ensured with o-rings for improved durability.The large dimensions of the gears increase the contact area allowing for greater torque transmission. Bearings are maintenance-free, with large tapered rollers. They are perfectly aligned with the one-piece distortion resistant housing and no additional adjustment is required. The bearing are held in place perfectly by the 18mm thick cast-iron bearing housing. No play is possible at tine holder, the splines on the rotor chaft are cold rolled into it, increasing the density of the metal. The connection with the shaft is perfect thanks to the conical centering of the tine holder. The tines have a high resistance to impact and wear thanks to the large surface area and volume of material.

Compact and robust casing

The housing, bearings and tine holders form a compact and very sturdy assembly. The small distance between the casing and the top of the tine holder prevents stones from jamming in this area. This small gap also directs the flow of soil towards the tines to be broken down into finer tilth.

Robust central gearbox in ductile cast iron

The central gearbox is robust and made of ductile cast iron with a straight and mechanical output to ensure a faultless rotor drive.

Work quality is key

Benefit from the working depth control

The maintenance-free CRUMBLER roller with large diameter allows appropriate soil consolidation while efficiently controlling the working depth. The HRB 202 power harrow can also be fitted with a PACKER 2 roller with 515mm diameter.

Benefit from genuine comfort

Design specifically adapted to YOUR needs

The low height, rounded profile and small widths make the HRB 102 SERIES power harrows ideal for specialized crop production. They are specifically adapted for operations in vineyards and orchards or market gardening. No compromises were made in relation to larger models with larger widths, with the drivelines designed for each model.

Easy transport!

The small dimensions of these machines ensures the easy and safe transport on roads and paths. You can easily travel on a narrow road in any situation.
