design, separation area has been
considerably increased. Lexion 8000
models have a massive concave area
of 1.55m2 and at 1.30m2 the concave
area on the narrow body Lexion
7000 is even more than that on the
current top of the range Lexion 780
at 1.26m2.
Due to the wider drum,
concave wrap is shallower and this,
combined with the new design
where all the APS Syn ow units are
virtually in a straight line, means
that not only is power and fuel use
reduced, but the straight ow of
material results in less straw
damage, improved grain quality
and increased throughput.
Due to the fact these new designs
have increased the throughput on
the latest Lexion 8000 and 7000
ranges, the grain tank capacity has
been increased up to 18,000 litres on
the new Lexion 8900.
Tank access has been improved

speed is now 180 litres/second with
an unloading time of just 100
seconds. e pivot angle of the
unloading auger has been changed
to 105 degrees, making it easier to
see from the cab.
Delivering power
MAN and Mercedes engines have
been chosen to power the new Lexion
7000 and 8000 combines ranging
from 408hp on the smallest Lexion
7400 to 790hp on the Lexion 8900.
“ e larger a machine is the more
power it requires to drive the drums
and rotors because of the increase in
crop going through the machine,”
says Hayward. “Nevetheless, the new
engines have been tted to meet
StageV emissions regulations.”
All models are tted with the
Dynamic Power intelligent engine
management system which
automatically adjusts engine power
output relative to load which results
in improved fuel e ciency.
Variable fan cooling from the
Dynamic Cooling system is also
standard. It draws clean air in from
above the combine and blows it out
down over the sides of the machine.
