Updates to the three widest Vario cutterbars for 2022 are designed to benefit performance, ease of operation, setup times and maintenance. Highlights include a new reel driveline and automatic reel height adjustment.
The new reel driveline on the Vario 1080 (10.8m), 1230 (12.3m) and 1380 (13.8m) delivers the torque directly from the hydraulic motor. Advantages over chain drive include the possibility to use the full 700mm adjustment range of the Vario table, even with rapeseed knives fitted, and maintenance intervals for the drive are extended from 100 to 500 operating hours.
Speaking of rapeseed knives, the new ones available next season feature mechanical drives with an integrated overload clutch and a 50% greater cutting force. The plug-in system with quick-release couplers allows them to be fitted without tools.
Pressure-dependent reel height adjustment automatically adjusts the reel speed to the ground speed. A sensor measures the hydraulic pressure in the reel drive. The level of drive torque necessary to trigger the control system and the response of the latter can be set separately in CEBIS.
The control unit for height adjustment fitted directly on the cutterbar has also been updated. In addition to enabling activation and deactivation of the appropriate work lights to aid fitting and removal of the cutterbar at night, this unit features a rotary switch which can be used to move the auger into both transport and cleaning positions. Another rotary switch can be used for infinitely variable adjustment of the auger height.
The updates continue with a new hydraulic height adjustment system for the intake auger. This allows the operator to react to changing harvesting conditions via the CEBIS terminal.
Access to the stripper bars has also been improved and fitting and removing the dividers for grain threshing is also easier with a new clamping system. Dividers continue to be available in three versions/lengths, as before.
