With variable bale chamber


  • The round baler – Comprima V 150 (XC), V 180 (XC) and V 210 XC
  • The combination baler wrapper – Comprima CV 150 XC
  • Variable diameters – infinitely variable 1.00-2.05 m bale diameters
  • Cost-effective – the simple and uncluttered design
  • Sharp blades – the XCut cutting system

Comprima V and CV from KRONE stand out for providing a superior flexibility and uncompromised stability as they perform in enduring and heavy-duty applications. They allow operators to set bale diameters steplessly from 1.00 m to 2.05 m to handle different crops, conditions and customer requirements.

The Comprima V 150 (XC), V 180 (XC) and V 210 XC with variable bale chambers allow operators to enter the required bale diameter to the operator terminal in the tractor cab. The diameters can be set steplessly from 1.00 m to 1.50 m or to 1.80 m or 2.05 m. This way you are set to handle all crops and conditions. Smaller bale sizes are often preferred in grass silage whereas larger bales are more typical in hay and straw. It is also possible to choose a softer core, which is useful in hay, for example, as it allows moisture to evaporate from the bale.

The Comprima X-treme CV 150 XC baler wrapper has a powerful twin-arm wrapper. The table forms a deep cradle and has bobbins on the sides that ensure the bale is effectively rolled during the wrapping cycle no matter the conditions. The Comprima CV 150 XC table can also be used for unloading the bales in pairs when no wrapping takes place.

The variable bale chamber on the Comprima V and CV models produces steplessly adjustable bale diameters of 1.00 m to 1.50 m or 1.80 m or 2.05 m. The specifi c diameter is entered to the cab-based control unit. Further custom parameters are the bale and core densities. These are set on a hydraulic pressure control valve, which can be electrical as an option. The pressure increases as the bale grows to ensure particularly uniform densities.

After the net has been applied to the bale inside the chamber, the tailgate opens and and the wrapping table tips to the rear to unload the bale that has just been completed, placing it on a rubber mat. As a next step, strong and chain-supported steel bars push the bale from the chamber onto to the wrapping table. As the baler resumes baling, the wrapper starts wrapping.

The variable bale chamber is formed by two belt-and-slat elevators. These form the bale as it grows to its preset diameter. The system uses a double swing at the front and the tensioning arm at the rear that combine with springs and hydraulic rams to progressively increase the pressure as the bale grows. This technology produces an exceptionally high baling pressure.
