The WINTERSTEIGER plot seeders have been specially developed for precise sowing of trial plots. A variety of distribution systems makes it possible to distribute the seed for a plot over multiple rows. The modular system with its many options allows you to customize the machine for many different applications.

Your benefits summed up:

  • Simple controls and excellent visibility for the driver and operator
  • Easy track width and row spacing adjustment
  • Wide application scope thanks to a variety of feeding variants
  • Seed placement for a variety of soil conditions thanks to a selection of opener systems

Distribution systems.

A combination of distribution systems can also be deployed.
Mounting 2 distribution systems side by side or behind/in front of one another allows for simultaneous sowing of two plots and/or spreading of fertilizer or microgranulate.

Belted cone.

The belted cone (diameter 195 or 290 mm) is suitable for any kind of sowing, from fine seeds, through grain, to legumes with large seeds.


Cell wheel

The cell wheel (diameter 265 or 400 mm) is mainly used for smaller seed sizes up to the size of grain.

Slope compensation.


Slope compensation.

Slope compensation ensures even distribution of seed in the belted cone/cell wheel and distributor housing despite
sloping ground. If you are sowing on a flat surface, you can work without slope compensation.

Seeder control units.

Two control units are available for the WINTERSTEIGER plot seeders:

While the PDS-E control unit can be regarded as a minimal version, the Global Seed Control (GSC) is the perfect solution for exacting requirements with respect to precision and control. 


PDS-E control unit.

  • ON/OFF for electrical power supply to seeder 
  • Actuates the seed distribution system
  • Funnel stroke time adjustment 
  • Horn button for audible signal by operator
  • Function monitoring (horn signal in case of malfunction)

Global Seed Control (GSC) control unit.

The GSC combines all features that guarantee best distribution accuracy and precision. 

The control unit is characterized by the following features:



  • Easy controls via function keys
  • Clear, high-contrast display 


Setting options:

  • User menu language setting 
  • Easy setting of different plot parameters, such as the plot length, cycle length, selected speed, start length, drive mode, and number of plots per trip 
  • Distribution system adjustment: selection of distribution system (e.g. belted cone, magazine, etc.) and setting of filling times (e.g. funnel stroke time, seed drop time)



  • Displays the drive train settings required for the selected plot parameters
  • Monitoring of all critical functions and malfunction cause display. In plot drilling, this means power monitoring of the rotary distributor so that feeding or the funnel stroke is blocked in case of a malfunction. 

Travel measuring system via measuring wheel.

The measuring wheel greatly facilitates sowing since there is no need for field markers; at the same time, it improves efficiency and precision. The GSC provides the following functions in combination with the measuring wheel:



  • The sowing cycle is triggered by a signal from the measuring wheel
  • A warning signal occurs in case of excessive speed

Opener systems.

The following opener systems are available for seed drilling:
