How many sections does ST have and is spacing adjustable?

Depending on model, 4 to 16 sections are available. Stepless adjustment fits every crop.

Does ST work with the PS attachment or third-party precision drills?

Yes. ST works with the dedicated PS attachment and most precision drills.

What is the tank capacity and can two fertilisers be applied?

Base capacity is 3900 l or 4900 l with extension. The 60/40 or 40/60 split handles two fertilisers or fertiliser and seed.

Are parts and service readily available?

We provide fast access to factory-stock parts and qualified mobile service.

Will I receive machine setup training?

Yes. Specialists assist with commissioning and crop-specific settings.

STRIP-TILL TECHNOLOGY

Cultivate only the seed strip

ST series cultivators are built to work without compromise. Instead of disturbing the entire field surface, you loosen only one third of the soil. This delivers substantial savings across the whole farm.

Retain water in the soil

Fertiliser within root reach

Fewer passes

Better soil structure

ST working section

6 steps to plant growth

One pass. Six perfectly synchronised working zones.

Step 1

Clearing and tearing discs

They clear the soil strip of crop residue and mulch, preparing the ideal space for the following components to work.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

Closing and gathering discs

They keep a loose layer of soil inside the cultivated strip, preventing moisture loss from the deeper layers.

Step 6

Off-set tyre roller

It effectively compacts the soil and levels its surface. The off-set system (wheel offset) eliminates clogging and reduces draft requirement.

CONSTRUCTION

Engineered to work without compromise

Four design solutions that determine the quality of ST work — expand each item to learn more.

Provides stability in the field position and safe road transport for a machine of this size.

Three operations in one pass

ST cultivators are designed to work with the dedicated PS coulter drill attachment or precision planters from leading third-party manufacturers.

1. Loosening
down to 35 cm in the soil profile.
2. Fertiliser placement
at two depths in the root development zone.
3. Seed drilling
with the PS attachment (wheat, peas, oilseed rape) or an external precision planter (maize, beet).

* Actual power requirements and configuration depend on soil type, working depth and number of working sections. An advisor will help select the right model and equipment for your farm.

PLUS expands the available row layouts of STK 300. STK data comes from the product catalogue. “—” means a parameter is not specified in the catalogue, not that equipment is absent.
