3.21 Isobus implement control system
The Valtra ISOBUS implement control system (extra equipment) complies with
the ISO 11783 standard.
The system connects together the tractor, the implement and the ISOBUS
terminal, and enables information exchange between these units.
The center part of the ISOBUS implement control system is Tractor ECU (TECU).
The Valtra TECU fulfils the Class 2 standard requirements. It transmits the
following information to the implements connected to the ISOBUS.
• Tractor speed information (radar, wheel and engine)
• Distance and direction
• Rear linkage position
• Power take-off (PTO) status and speed
• Auxiliary hydraulics status
• Lighting control
Valtra TECU provides also electric power for ISOBUS components (25 A) and
electric power for actuators and implements (60 A). TECU can maintain the
power for a maximum of one hour if an implement or the terminal requires so.
NOTE: The main power of the tractor is on for a maximum of one hour after the
ignition switch is turned off.
