Eight versions of the Duplex are available depending on the cutting width and the type of tooth:
- Duplex 1.68 Gold or ST: 1.68 m cutting width
- Duplex 1.82 Gold or ST: 1.82 m cutting width
- Duplex 2.12 Gold or ST: 2.12 m cutting width
- Duplex 2.42 Gold or ST: 2.42 m cutting width
The Gold version is distinguished by double section teeth (distance between tips of 76 mm), while the ST version is distinguished by triple section teeth (distance between tips of 50 mm) and it is recommended for stony soils.
The compact and sturdy load-bearing frame was devised to minimise the overhang of the cutter bar with respect to the tractor and to optimise weight distribution.
The hydraulic lifting, supplied as standard, allows the positioning of the bar from +90° (i.e. vertically) during field manoeuvres and during road transfer, and it operates trouble-free up to - 55° with respect to the horizontal plane.
Thelinkages have been designed to provide a continuous flow of movement to the cutting unit, retaining maximum efficiency over time. The high number of strokes per minute at which they are calibrated, permitted by the use of very high quality materials, ensures optimum operation even at low engine revs.
