6 steps to plant growth
The same innovative strip cultivation and deep-fertilisation technology as in the large ST cultivators, optimised for smaller tractors.
Clearing and tearing discs
They clear the soil strip of crop residue and mulch, preparing the ideal space for the following components to work.
Wavy cutting coulter
It cuts the soil to a depth of 12 cm and lets the tine enter as non-invasively as possible, preventing the machine from clogging.
Vertical loosening and aerating tine
It works to a depth of 35 cm; its shape causes no soil-mixing effect, preserving the natural capillary structure and protecting moisture.
Fertiliser application nozzle
It ensures precise placement of one or two types of fertiliser across the entire profile of the loosened soil in the root-development zone.
Closing and gathering discs
They keep a loose layer of soil inside the cultivated strip, preventing moisture loss from the deeper layers.
Off-set tyre roller
It effectively compacts the soil and levels its surface. The off-set system eliminates clogging in wetter conditions.
Is the STK right for you?
The STK series consists of medium-scale machines — manoeuvrable, low on power demand and yet fully equipped. Built by a farmer, with everyday field work in mind.
The STK is for you if…
- ✓You run a medium-scale farm or provide field services
- ✓You want to reduce the number of passes, fuel and fertiliser use
- ✓You care about retaining water and improving soil structure
- ✓You grow oilseed rape, cereals, maize, beets or legumes
- ✓You have a tractor from 160 HP (STK 300) or 180 HP (STK 400)
What the STK offers
- ✓Dual-chamber tank 2×1400 l — two fertilisers in a single pass
- ✓Stepless adjustment of section spacing (from 4 to 9 sections)
- ✓Working depth adjustable within 20–35 cm
- ✓Electric metering units made of acid-resistant steel
- ✓Ø 89 cm off-set tyre roller
- ✓Non-stop protection on every component
One machine, the whole crop rotation
Stepless spacing adjustment and interchangeable chisels mean the STK moves from crop to crop without compromise — from oilseed rape and cereals to beets, maize and legumes.
| Crop | Section spacing | Chisel |
|---|---|---|
| Winter oilseed rape | 6×45 / 7×42.8 cm | 45 mm chisel |
| Cereals | 7×42.8 / 9×44.4 cm | 60 mm chisel |
| Sugar beet | 6×45 cm | 60 mm chisel |
| Maize and sunflower | 5×75 cm | 80 mm chisel |
| Soya and legumes | 6×50 cm | 45 mm chisel |
