HE-VA’s Disc Roller Contour is a high speed multipurpose primary and secondary cultivator suitable for any farm. Importantly it’s simple to use with the disc depth hydraulically operated from within the tractor cab. To make a stale seedbed or prepare a seedbed for drilling it is important that the cultivator follows the contours of the field to ensure areas in the field are not under or over cultivated or consolidated as this will undoubtedly effect the crop growth and yield at harvest. The Disc Roller Contour combats this with its unique contour following system which means that when a machine is unfolded it is not ridged across its working width. The system comes into its own when working at a shallow depth when ground can be missed in a weed chit situation. A situation that is usually overcome, by other disc cultivators, by working the discs deeper.
Unlike traditional concave discs or aggressively angled discs that lift soil and cut out “grooves” forming a corrugation effect under the surface, HE-VA’s DSD, depth synchronised disc, system works to move the whole soil surface and is effective in both shallow soils and at depth. The 510mm Sabre discs pull themselves into the ground which assists penetration meaning more soil is inverted and residue incorporated.
HE-VA’s Disc Roller Contour is available as a rigid machine, working widths 2.75m & 3.25m and as a two or three section folding machine. Two section cultivators with working widths of 4.25m – 6.25m and a three section machine with working widths of 7.75m. The Disc Roller Contour is available with either a single or twin roller and a number of front tool options on the trailed models. These include Top Cutter for mechanical cover crop destruction, shatta and slicer boards for aggressive levelling ahead of the discs or straw tines.
