  • Tried and tested external ISOBUS control unit
  • High operating safety

...for agricultural machinery, forestry vehicles, municipal technology and other mobile machinery – the WTK field-handle allows frequently used control functions in the ISOBUS terminal to be allocated to joystick buttons, allowing comfortable and fatigue free operation.

It offers you a number of beneficial features:

  • It is easy to mount in the cab in the ideal position for the operator.
  • The electronics are integrated into the joystick.
  • The field-handle is an ISO 11783-compliant additional external input device for an ISOBUS terminal (Auxiliary Control Assignment), allowing quick and focussed access to job computer functions.
  • 8 function keys can be operated at 3 levels using a toggle switch on the back of the joystick. This means that a total of 24 assignable functions can be easily controlled from the handle.
  • A 3-coloured LED on the front of the joystick indicates the selected active level, with either red, yellow or green. The day/night mode of the LED allows glare-free working and ease of recognition.
  • In accordance with the ISOBUS standard, the operator is free to select which functions they wish to assign to which key. Each key function is allocated through the ISOBUS terminal used.
  • A safety key (dead man’s switch) on the multifunctional joystick provides greater operational safety for machine functions.
  • field-handle displays assigned functions on its main data screen on the ISOBUS terminal. The display is changed with the level toggle on the back. With the settings data screen, the operator can alter the safety level for each individual operating level (duration that the active key function will continue before automatic locking after activating the safety switch).
  • To indicate the active status of the multi-function handle visually, the three-colour LED of the current level flashes.

  • Tried and tested ergonomic handle shape
  • Design with switches, buttons or rocker switches to meet customer requirements using the following types:
