From the Mega 8000 collection, the 8400 became a favorite, which was especially popular
as a contracting machine. After the introduction of the 8050 series, the 8400 was retained
in production, but it received a few reforms. Lift force was increased by 7
to a ton. However, the engine represented an older generation than the same one
in the powerful 8450. Autocontrol was updated to version 2.1, which had the so-called
forced descent function. One secret of the 8400's popularity was the traffic tractor version,
which competitors with speeds of 50 km/h did not have in the mid-90s
offer.
In the spring of 2000, the engine was changed to a newer version. The power increased e.g.
thanks to the new nozzles to 150 horsepower and the torque increased as much
with 105 Nm. The increase in torque was 31% instead of the previous 16%. As standard equipment

In the spring of 2002, the power was further increased to 160 horsepower and became standard equipment
came millirings. The engine now had a visco fan. 8400 was also received now
as a long wheelbase version. The 8400 was discontinued only after the T Classic models
after the presentation.
