Comprima F 155 and F 155 XC with semi-variable bale chamber are the first round balers that operate on the fixed chamber principle whilst producing bales of variable diameters that range from 1.25 m to 1.50 m (4’1″ to 4’11”). Combining the functions of both fixed and variable chambers, the semi-variable chamber is a unique system on the world market. Relying on the new NovoGrip system, the design combines quiet running with high baling pressure. Comprima F155 XC features the XCut rotor cutter with up to 26 blades.
