    Default pictures of DD9

    I talking was about it to a fellow that had been a Cat salesman or rep. I believe that he said there were 81 of them made and sent all over the world.

    Here are a couple of pictures that I took last year:

    Default Steering A DD9

    Hi Team,
    by the vid. it would seem there could be an issue with crossed steering lines to the rear machine. The front unit is trying to turn left and the rear unit is trying to go to the right, or is this how they are meant to be set up for large radius turns and, this is what happens in short radius turns?
    These machines were announced in Product Bulletin, Oct 18 1968, just happens this one is not in my bound copy of the years 1968/9.
    Cheers,
    Eddie B.

    Default steering DD9

    Thanks for jogging my memory Eddie B. I overheard the Cat rep explain to someone that the rear D9 is supposed to just "release" the steering clutch in the direction of turn and follow. At least that is what I thought he explained. It certainly doesn't look like that was happening though.

    Default Steer Sequence

    Hi Pete,
    sorry, I forgot to Thank You for posting the above vids etc.
    Yes, it makes sense for A track on the rear machine to release the steer clutch only as the rear machine can then follow the radius of swing of the hitch, which will be opposite of the way you are turning the front unit for the initial start of the turn.
    Cheers,
    Eddie B.

    Default DD9 steering.

    Hi, Folks.
    I could be wrong - it has been known to happen before - but I think that most of what you are seeing there is simply that the rear tractor was not being given enough loud pedal. At one point, there is a glimpse of the far track on the rear tractor which was on the inside of the turn actually rolling while the outside track was being dragged and there is almost no smoke coming from the stack of the rear tractor while the front tractor is belching big mobs of that politically IN-correct but nevertheless LOVELY black stuff.

    Steering could have been complicated on those jiggers 'cos there would have been times when you needed both tracks on the same side to have power, i.e. during a turn, and other times when you would have needed diagonally opposite tracks to have power, i.e. entering or exiting a turn - - - or just drag the back tractor with the front one as it appears in that video.

    Hi, EDB.
    There wuz ackshully at least wunna them jiggers may dit DowNunder. Bell Bros, W.A., had a set of DD9G's down at Pinjarra on a mudlake contract for the alumina smelter there. That would have been around 1969-70 if I remember kee-reckt-ly. I got to see them pretty much fully rigged in Wigmore's yard at Guildford, pre-delivery.

    Bell's also had 2 x Hough D500s down there. Traitors!

    Hi, PeterC.
    Thanks for posting that video. Good stuff.
