Güstrower
German engineering for two moments in the field: even spreading and efficient logistics.
Güstrower really focuses on just two things.
Delivering solid materials — fertiliser, lime, compost — with maximum precision.
And the logistics of these materials in the field — without downtime at harvest, sowing and fertilising.
Everything the company designs is subordinated to these two tasks. Hence its own description of itself: “machines designed by engineers — not by the marketing department”.
Every fertilising and liming operation consists of two processes.
- 01Deliver the material to the field.
- 02Spread it evenly.
If even one stage works badly, yield is lost. That is why the factory builds two entirely different machines, one for each bottleneck.
Each of the two bottlenecks can by itself undo the effect of the other.
Excellent spreading won't help if the material doesn't arrive within the weather window. Efficient logistics achieve nothing if the dose is laid in strips. Güstrower designs a separate machine for each of them — and that is its entire product strategy.

What if the logistics are weaker than the spreader?
Queue at loading, a lost weather window, expensive machinery standing idle. The answer is the GTU transfer cart: on-the-move transfer of up to 15 m³/min, without stopping the combine.
Go to the GTU pathWhat if logistics are excellent but the distribution is poor?
Tramlines in the field, excess fertiliser, crop losses. The answer is the GDK spreader: even distribution across a working width of up to 42 m, calibrated at the Danish research centre Bygholm.
Go to the GDK path
Güstrower does not try to do everything.
Instead of dozens of machines, a few directions, refined over years. That is why many design solutions look unusual: they follow how the material behaves, not a catalogue.
The floor is a chain conveyor, not a belt, because damp lime, compost and manure slide on rubber. The transverse distribution is calibrated at the Danish centre Bygholm, not merely declared in a brochure. And one machine handles many materials thanks to interchangeable spreading units, instead of three separate spreaders.


We did not look for the brand with the largest catalogue.
We looked for a manufacturer that solves two field bottlenecks with one engineering logic, and does not compromise on difficult materials. We chose Güstrower because its chain conveyor really copes with damp lime and compost where a belt slips; because the distribution is calibrated at Bygholm, not merely promised; and because one machine handles fertiliser, lime and compost instead of three separate ones.
As importer, we are responsible in Poland for commissioning, warranty and parts availability, for both lines, GDK and GTU.
Conversation with an engineer.
The most common questions we hear from farms before they choose a manufacturer.
We have collected the questions we most often hear from farms before purchase — and the answers from our engineers. Every answer is based on verified knowledge of the machine.

Both lines are ISOBUS UT Ready (Universal Terminal). The GDK supports the full Smart Farming stack: Section Control (TC-SC), VRA application maps (TC-GEO), task controller (TC-BAS), and AUX-N for additional switches. The machine works with any ISOBUS-compliant tractor monitor — John Deere, Fendt, Claas, New Holland, Case IH, Massey Ferguson, Valtra.
As importer, RUTHENIA ALBA is responsible for commissioning, warranty and after-sales support for GÜSTROWER machines in Poland. Spare parts for GDK spreaders and GTU grain carts are kept in our warehouse, with availability within 24–48 h for fast-moving items (conveyor chains, spreading discs, bearings, hydraulic components).
YES — RUTHENIA ALBA supplies parts even for machines 40 years old. The GÜSTROWER D series and older Fortschritt machines are the predecessors of today's GDK spreaders, so we service them within the same service line and spare parts range.
The required power and hydraulic specifications of the tractor depend on the GDK model. The single-axle GDK 6000 and GDK 8000 work approximately with tractors from about 120 hp, and the twin-axle GDK 9000 and GDK 10000 from about 180 hp. In the standard configuration, the spreading discs and chain floor conveyor are driven by the tractor's hydraulics (approximately 95 l/min for the discs + 60 l/min for the conveyor). Optionally, the GDK can be configured with an independent onboard hydraulic system; in this version the demands on the tractor's hydraulics are significantly lower, which also allows it to work with older tractors. All models require brake air. ISOBUS and Smart Farming are not a condition for basic operation of the machine. Full functionality (Section Control, VRA application maps, Task Controller) requires an ISOBUS UT or compatible terminal; on tractors without built-in ISOBUS, an external ISOBUS terminal can be added, depending on the configuration.
Yes — this is one of the main applications of the GDK line. The chain conveyor handles both granulated and powdered lime. With powdered lime, factory-fitted dust covers are recommended. Working width for granulated lime: usually 24–36 m; for powdered lime: 12–18 m. Rate continuously adjustable 40–16,000 kg/ha.
The GTU is a transport wagon with a conveyor floor and side discharge outlet, with a capacity of up to 15 m³/min. On-the-go transfer function: the combine empties its bunker into the GTU without stopping, and the GTU carries the grain to a transport trailer or silo. An ordinary grain trailer requires the combine to pause work for the time of travel and unloading; the GTU eliminates this downtime.
Yes. RUTHENIA ALBA works with Polish financial institutions serving the agricultural sector — operating leasing, finance leasing and investment loans with PROW and KPO grants. We discuss financing options individually once the machine configuration is specified and the farm profile is established. The /finansowanie section contains the basic variants.

What if the next decision is liquid fertiliser application?
Duport — liquid fertilisation / CULTAN →This is not a random neighbouring topic. Güstrower injectors (GFI) are no longer manufactured. After the takeover, the injector line moved to Duport, and today only Duport Liquiliser applicators are built. Güstrower has stayed with what it does best: spreading granular material (GDK) and harvest logistics (GTU). For GFI injectors still in operation, we provide service and spare parts.
