Draper cutterbars are used wherever low-growing and low-fruiting stalk crops or difficult conditions (laid crops, volunteers) necessitate very flat cutting.
CONVIO FLEX, with its flexible knife bar, has been developed for universal use in all threshing crops, such as grains, rapeseed, soybeans, peas, grass and many others. CONVIO (with a rigid knife bar) is particularly suited to grains.
The constant crop flow through the cutterbar provides the combine harvester with an even, high-volume supply of crop material.
CONVIO cutterbars provide the operator with a variety of assistance systems which can be operated from inside the cab. These include automatic reel torque control, AUTOMATIC BELT SPEED and AUTO FLEX which ensure that the cutterbar is automatically adjusted to the optimal configuration.
Hydropneumatically suspended stabiliser wheels prevent the cutterbar from rocking when operating in uneven terrain. This feature also ensures smooth cutterbar guidance at high ground speeds and enhances driving comfort.

The lighting package provides good all-round visibility when operating in the dark and using large working widths. Work lights on the left and right sidewalls illuminate the crop edge. The work lights at left and right on the back panel allow the stubble immediately behind the cutterbar to be monitored.
Powerful work lights illuminate both side belts in the cutterbar trough. This allows you to continue to monitor – and if necessary optimise – the crop flow on the belts when operating during the hours of darkness.
All the crop lifters have tool-free quick-release mounts which allow them to be fitted and removed extremely rapidly. You can therefore count on your cutterbar being ready for action again quickly if the crop lifters are damaged or have to be replaced when changing to harvesting a different crop.
The drive train of the cutterbar consists of two parts. The mechanical part drives the intake auger and knife bar while the hydraulic part drives the side belts, the centre belt, the reel and the rapeseed knives. An overload protection feature protects the entire drive train against damage.
Powerful mechanical reversing of the intake auger and the feeder housing is possible when these units are stationary.
Depending on the working width, the linear drive is transmitted to the knife bar by one or two planetary gear units.
The newly developed reel with its innovatively shaped, adjustable cam track allows the reel tines to pick up the crop before it is cut, thereby keeping front attachment losses to a minimum, especially in lodged grain. In short crops in particular, the tines optimise the feeding of the crop into the cutterbar. In addition, the unique flip-over concept prevents the crop from wrapping on the reel. In this way, the crop is fed efficiently, consistently and with minimal losses onto the belts of the CONVIO cutterbar, from where it is delivered evenly into the combine harvester.
Thanks to the hydraulic reel drive, the torque applied to the reel can be adjusted automatically to cope with difficult harvesting conditions, such as lodged crops. An automatic height control system, which operates on the basis of the programmed pressure and sensitivity levels, prevents the tines from digging into the ground.
The AUTOMATIC BELT SPEED operator assistance system adjusts the speed of the belts to the harvesting speed continuously and completely automatically – and accommodates all crop conditions.

CONVIO FLEX is equipped as standard with the ACTIVE FLOAT hydropneumatic suspension. This suspension system allows the ground pressure of the knife bar to be adjusted to the field conditions from the cab while on the move.
Maximum reduction in operator workload with optimal cutting performance – CONVIO FLEX can be used in four different modes:
Cutterbar table and knife bar are set to a rigid configuration.
The knife bar is rigid but can be changed to flexible mode with a touch of a button while on the move. This is especially useful for avoiding crop losses when dealing with isolated lodged crop areas during grain harvesting.
When manual flex mode is activated, the knife bar resting on its skids but exerting no ground pressure follows the ground contours. The flexible knife bar can avoid obstacles with a 90 mm upward deflection and also follow the ground contours with a downward deflection of 135 mm. With a total flex range of 225 mm, CONVIO FLEX is therefore able to adjust to practically all ground conditions.
AUTO FLEX is a self-learning system which automatically optimises the height of the front attachment on the basis of the ground contours and thereby offers a number of important advantages:
