WALKAROUND
The DD grader is small and compact in
comparison to today’s graders and was
represented in Australia in two models, the “D”
being the petrol version and the “DD” Model
being the diesel version.
As one would expect there are a few signs that
tell us that some serious welding maintenance
has been done on the grader over 50 years of
heavy work. On other graders I have seen a lot
of welding being done on the front tubular steel
cross member.
However, this machine is a newer version and
has the solid square billet incorporated into its
build. When the original dimensional tubular
frame was not available in Australia, Tutts

redesignedtheframewitha solid10”square

steel billet.Thisgavemorestrengthandweight

the local graders picked up the outers left from

the manufacture of these wheels.

Cost effective, strong and locally available:

win, win, win.

1. A look under the hood


2. Going down in history –
   the day the filters were
   changed


3. The control levers would
   sort out the best of
   operators


4. The cabin is sparse but
   vision is good. There’s no air
   conditioning, radio, heater
   or fan in this old girl, but
   that’s how it was done
