7.5 - FRONT DUAL CONTROL
7.5.1 - General
The “Front Dual Control” is identical to the “Rear Dual Con-
trol”, controlling the front implement (e.g.: plough, cultiva-
tor, roller) at soil entry and exit, and automatically transmits
position and applied draft changes to the rear implement in
order to obtain simultaneous horizontal movement.
The information necessary for operation of the system is
transmitted to the “DATA 2” onboard computer via the
sensors and the electronic linkage calculator.
This system is currently available on tractors fitted with
"LOAD SENSING" hydraulics.
NOTE: Tractors fitted with ‘Front Dual Control’ are auto-
matically fitted with “Rear Dual Control”, however the
two systems cannot be used together.
