Beyond its style, it differs a lot of existing models, because of the unique rotary-driven star-wheels design and operation. Its original action on the soil provides striking outcomes : crust removal without projection, up-the-seed layer packing and upper layer structuring, weeds elimination by the combination star-wheels + comb arrow.
The unique wheel’s spoon-bill teeth, curved upwards, work without digging, by gravity. It’s operation does not require a high driving speed. Under any soil condition, even then most demanding ones (slaking crusty, clay, pebbly or residue-cluttered soils),it operates with effectiveness from 6 to 15 km/h, with ow impact on the growing crop. Thanks to its 2,3 tons-weight (6m), the HELIOS rotary hoe lands itself spontaneously in the soil with full respect of the depth to remain above the seedbed. Thereby it allows crossing the passes. The «wheels + comb» combination enhances the weeding effectiveness about 40%.
By tackling the soil surface with the"back of the spoon" the wheels generate a cracking impact propagated over 3 cm both sides of their way, being a 6 cm-wide stripe tilled at a 3-cm depth. This operation will prepare for the pass of the comb harrow’s teeth and help an accurate control of it’s work, preserving the seedbed. By disrupting the topsoil’s upper layer, the harrow restores the fluids, water, air, vertical flow s and stimulates physico-chemical reactions and soil life.
By cutting the rising damp from the surface, the HELIOS rotary hoe reduces evaporation water losses. By blocking it under the packed layer, it saves water reserve in the seedbed layer. This bonus will also be profitable for the crop’s start and growth.
Thanks to their narrowed profile and their unique upwards teeth curving, the wheels properly operate in any conditions : with no earth spreading into maize’s cones or pebbles blocking mechanics.
Directly fitted to the chassis, with adjustable ground pressure for depth control. Adjustable comb angle, 3 fixed + 1 floating position. Interposed wheels and harrow pass.
ENSURED ACCURACY OVER THE WHOLE WORKING WIDTH Whatever the terrain: bumps, wheel tracks… Each element keeps the same equal ground pressure whatever its position. The standard version features individual arm pressure settings, the hydraulic version a centralised setting.
Shorter design to allow a combined work of both wheels and then a stronger action onto the ground. Oversized heavy-duty wear-resistant bearing. Guides ensure a perfect wheels alignment in the motion direction, even when lateral stress occurs.
The double H-shaped boom provides maximum stiffness to the elements mounting. Safe from wear and slack, the elements assembly is fitted with polymer-bushed tapered shafts.
For a safe transport in folded position, with no risk of inadvertent release and no wear or slack.
whatever the soil’s textures with or without pebbles.
leaves-stage cereals, 6-leaves stage maize and 30cm sunflower.
