The M809
general utility truck was based on a successful M54 series design,
that entered production in 1950 and remained in production for over
30 years. Over 92 000 of the M809 series trucks were built. These
trucks retained the classic American military truck appearance with
the long bonnet, spartan soft-topped cab, and a large carrying area.
In the 1980s the M809 series trucks were supplemented, but not
replaced with improved
M939 series. The M809 series trucks were eventually replaced with a new
MTV family of 6x6 utility trucks,
however they still remain in service with many other nations.
The main
purpose of the M809 truck is to transport troops, cargo and
materials over all types of roads, terrain and in all weather
conditions. Vehicle has a payload capacity of about 4 500 kg. The cargo
versions were often used as artillery tractors.
The M809
referred to the chassis type. There were also M810, M811 and M812
chassis.
The M809
truck is powered by Cummins NHC-250 diesel engine, developing 250
hp. Previous M54 series trucks were powered by a petrol engine.
Vehicle is fitted with a central tyre inflation system, which was
developed and patented by AM General. This system features driver
activated dashboard controls that adjust tyre pressure to suit
terrain conditions, while the vehicle is in motion. All models could
be optionally fitted with winches, deep wading kits, cold weather
kits and so on.
Numerous
variations of the M809 series models have appeared over the years.
