The ISO control
system
The ISO control system uses the ISOBUS communication protocol,
which makes it suitable for tractors that are also equipped with an
ISOBUS communication system. For tractors that still do not have an
ISOBUS connection, your dealer can supply an ECU box to which you
can connect all ISOBUS machines.
The automatic weighing
system
The spreader uses a weigh cell in the three-point linkage to continu-
ously measure the quantity of fertiliser that is being spread. The
computer in the distribution box compares these values with the set
application rate and corrects as needed by further opening or closing
the dosing unit. The tractor's electronics or an extra sensor measures
the current required driving speed.
