Sub-Tiller
The Flexible Subsoiler
The HE-VA Sub-Tiller is a heavy-duty subsoiler featuring a unique V-shaped design that reduces draft requirement and enables greater working widths.
The Sub-Tiller can easily be adapted to local conditions. Tine spacing can be adjusted and unnecessary tines removed — for example when subsoiling tramlines.
The Sub-Tiller can work down to a maximum depth of 600 mm. The points are fitted with 200 mm wing shares that lift and loosen the soil at the selected working depth. The point design ensures that stones and raw subsoil are not brought to the surface. The Sub-Tiller can be equipped with different points. See the selection under extra equipment above.
High Efficiency with Stone Protection
Stony Soil Types
Hydraulic stone protection
For stony soil types, a HE-VA Sub-Tiller can be equipped with hydraulic stone protection. A cylinder on each tine ensure that the tines automatically swing upwards to deviate from the obstacles in the soil.
Loam Soils
Quick-Push stone protection
For top soil without stones and when subsoiling a small amount of acres, the Quick-Push stone protection proves very efficient. A special shearbolt with 8 steps per bolt will be cut, if the tine hits a stone. So just remove the R-clip, place the shearbolt one notch forward and after having mounted the R-clip again, you can continue your work. Simple and easy without using any tools.
Control of Reconsolidation and Working Depth
With the correct roller, the soil receives the required reconsolidation while also controlling the subsoiler’s working depth, reducing unnecessary strain on the tractor linkage. The soil-seeking effect of the points also helps press the roller into the ground, improving reconsolidation. The HE-VA Sub-Tiller can operate without reconsolidation or be equipped with different rollers depending on the model.
The Square Tube Roller provides excellent depth control and crushes soil clods effectively on lighter soils.
The V-Profile Roller provides aggressive clod crushing and leaves the soil surface smooth and level.
The Star Roller leaves the soil consolidated with a loose structure and a slightly ridged surface.
Trailed Sub-Tiller

The trailed Sub-Tiller can be equipped with a V-Profile Roller for aggressive clod crushing and a level surface finish.
Three-Point Mounted Sub-Tiller

Three-point mounted Sub-Tillers can be equipped with three different rollers — Square Tube Roller, V-Profile Roller and Star Roller.
The Square Tube Roller is ideal for lighter soil types, while the Star Roller excels in highly effective reconsolidation.
Till-seeding
With a Sub-Tiller operating simultaneously with sowing, optimal growth conditions can be created for crops such as oilseed rape and cover crops including mustard and oil radish.


Plant roots gain unrestricted access to deeper soil layers, resulting in stronger roots and larger root systems — creating the foundation for high yields.
