Krone presents its new PreSelect machine operation system. The new system makes it possible to preselect the hydraulic functions of the connected attachment devices and then activate them with the regulating valves on the tractor side. It enables easy and intuitive operation.
Electrical functions, such as adjusting the bearing pressure, can be performed directly. It will be available in two versions: The PreSelect DS 50 presents the new preselect operation unit in the new design. As an alternative to this, the PreSelect Digital has a connector cable that connects the machine with the tractor’s ISOBUS plug. The hydraulic functions can then be viewed and preselected via the tractor’s ISOBUS terminal. This form of machine operation has proven to be very flexible. That is because it is possible to change between PreSelect DS 50 and PreSelect Digital. Krone PreSelect will initially be introduced in the Butterfly combinations Krone EasyCut B 870, B 1000 and B 950 Collect and will also be available for other machine groups in the future.
Krone PreSelect DS 50
The PreSelect DS 50 appears in a modern design based on the DS 100 operation unit. The connection is directly to the machine interface and is supplied with voltage via a 12V plug in the cabin. The PreSelect DS 50 offers ergonomic single-hand operation with membrane keys. In the Butterfly combinations, for example, various hydraulic functions including one and two-sided lifting of the mower units, adjustment of the working width and swivelling the cross conveyor belt in and out can be preselected and then performed by activating the tractor’s control devices. The status LEDs indicate the status of the drives (active/inactive), the transport position of the mowers and the current preselection of the hydraulic functions. The bearing pressure of the mower units and the speed of the cross conveyor belts are shown in the display and can be adapted using the “Minus” and “Plus” keys.
Krone PreSelect Digital
The PreSelect Digital performs essentially the same tasks as the PreSelect DS 50. The difference is that with the cable link between the attachment device and the tractor’s ISOBUS socket, the driver can view and make preselections on an ISOBUS terminal. This makes it possible to preselect hydraulic functions of the connected attachment devices by means of the electrical PreSelect Digital on the ISOBUS terminal and then activate them with the regulating valves on the tractor side. The icons show which functions are currently preselected. The PreSelect Digital also has an integrated hour counter and the speeds of the mowers are displayed. The bearing pressure and the speed of the cross conveyor belts can be adjusted by pressing the icons. One great advantage is the option to preselect a function and carry out activation of the control unit via the AUX buttons on the tractor’s ISOBUS-capable control lever. the ISOBUS-capable control lever of the tractor. In this way all tractor and machine functions can be operated conveniently with a joystick and without having to reach around.
