Lemken Rubin 12 Compact Disc
The LEMKEN Rubin 12 Compact Disc Harrow is built for producers who need deeper cultivation than a traditional compact disc harrow can provide. With working depths up to 7.9 in. (20 cm), it is suitable for both intensive stubble cultivation and primary soil tillage, even in heavy soil conditions. Available in mounted and semi-mounted configurations with working widths from 9.8 to 23 ft (3 to 7 m), the Rubin 12 combines large 29 in. (736 mm) serrated concave discs, symmetrical disc placement and generous frame clearance to deliver thorough mixing, excellent residue incorporation and clog-free operation. Maintenance-free disc bearings and individually sprung disc legs help keep the machine working efficiently while reducing routine maintenance.

What is the maximum working depth of the LEMKEN Rubin 12?
The Rubin 12 can work at depths up to 7.9 inches (20 cm), making it suitable for both intensive stubble cultivation and primary soil tillage. This deeper working capability allows it to incorporate significant amounts of crop residue while preparing the soil in demanding field conditions.
How does the Rubin 12 reduce side draft?
The Rubin 12 uses two rows of large serrated discs arranged symmetrically across the machine. This balanced design improves directional stability, eliminates lateral pull and provides even cultivation across the full working width, including when operating on slopes or at higher field speeds.
Can the Rubin 12 handle heavy crop residue?
Yes. Large 29-inch (736 mm) serrated discs, generous spacing between the disc rows and 31.5 inches (80 cm) of frame clearance allow the Rubin 12 to operate with minimal blockages, even where large volumes of crop residue are present.
Does the Rubin 12 require frequent bearing maintenance?
No. The disc bearings are maintenance-free angular ball bearings that do not require lubrication or adjustment. Protective caps help prevent dust, moisture, wire and twine from reaching the bearing seals, helping reduce routine maintenance.
What Rubin 12 models are available?
The Rubin 12 is offered as a mounted model in 9.8 ft (3 m) working widths and as hydraulically folding semi-mounted models from 13.1 to 23 ft (4 to 7 m). Semi-mounted models include hydraulic working depth adjustment and an integrated carriage for improved transport and manoeuvrability.
