Stealth
Low-disturbance subsoiling
The Stealth significantly reduces surface disturbance compared with a traditional subsoiler. This results in reduced emergence of waste grains and weeds while minimizing mixing between upper and lower soil layers. Stealth also improves drainage, aeration, nitrogen uptake and crop rooting - contributing to improved soil health and crop performance.
The tines on the Stealth are arranged in two rows, allowing excess material to pass easily through the machine while reducing tractor draft and lifting requirements. Stealth has a working depth of 0–300 mm and can be adjusted hydraulically directly from the tractor seat using HE-VA hydraulic depth control.
High Efficiency with Stone Protection
Stony Soil Types
Hydraulic stone protection
For very stony soil types, it is recommended that the HE-VA Stealth is equipped with hydraulic stone protection. A cylinder on each tine ensures that the tines automatically swing upwards to deviate from the obstackles in the soil.
Loam Soils
Quick-Push stone protection
Quick-Push stone protection on Stealth is an effective tool. A specially designed shearbolt with grooves is cut across if the tine encounters stone. The split pin is removed, the safety bolt is pushed into place and the split pin is reassembled. You can then continue the work.
Rollers
Synchrone Roller 300/55 reconsolidates the soil precisely where cultivation takes place, leaving the surrounding soil undisturbed.
V-Profile Roller provides aggressive clod crushing and leaves the soil surface smooth and level.
Star Roller leaves the soil consolidated with a loose structure and a slightly ridged surface.
Till-Seeding
With a Stealth 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 - laying the foundation for high yields.
