    The track frames are set out wider than a standard track Machine, the blade does stick out wider than the tracks but not by 18” on each side. No doubt in hindsight a narrow machine is much better than a wide one for finishing and grading, I have learned that.
    Yes that is the best way is to run part of the blade on something that is already leveled and smooth and let the other side cut

    This is the method I use to train new operators to hold grade. It works for both cutting and filling. Also works for dozers, track loaders and CTLS.

    The 1/2 pass method allows one track frame to stay on the desired grade at all times. If the operator has the bubble in their arse then they can feel when the machine gets off grade.

    Angling the blade helps immensely sometimes when the blade hop starts.
    Making a second pass at angle from the first pass helps also.
    Angle blade dozers have to have a wide blade so that when the blade is at it's utmost amount of angle, the outside of the tracks are still within the blade cutting width.
    The more material in front of the blade the better it is to prevent the blade from hopping.
    I hated narrow tracked dozers. I had to run a narrow tracked D6R and it hated me more than I hated it.:mad:

    The one in the background belongs to a lady friend. Only child of the only child of a John Deere dealer. I don't think she was born when the crawler was built, but it has never left her family. Her husband built the power angle for the blade. He graded about 20 acres with it last summer. I pushed the stumps & boulders, gave it a vague shape with my TD7G, he took over from there.

    Tinker so you prefer wider pads to narrow ones?
    Yes on this one you have to run the blade at some angle pretty much all the time to try and trim something to grade, unless your just bulk pushing dirt

    There is the base design 'Pivot' Mount just ahead of the Drive Sprocket, then will be a cross tractor cross member attached to Both rail trucks(Undercarriage Frames) play here is impossible to counter for as the trucks will move independent of each other and the tractor base frame.

    Yes , I prefer wide tracks. 1000 times yes !
    Only for finish grade, especially on slopes. Doesn't matter if it is sub-grading them or spreading black dirt.
    LPG's will go on slopes in terrible conditions. Even in decent material the LPG can turn quite fast and not tear up your work.
    Some slope work required a D6 to get decent production. The size (area) determined if a D6 was a better choice.
    For smaller ditches and smaller slopes I was in hog heaven on a John Deere 450 (any series). 6 way blades also increased an operators production per hour.
    If the blade could only be angled it would be like being in a fist fight with one hand tied behind your back !
    The contractor I spent most of my career with didn't buy any wide tracked dozers without a 6 way blade.
    Cutting bigger slopes such as following scrapers required a D8 to be able to keep up with them.
    Sorry for being long winded post, but after running dozers for about 30 years I could go on and about running them.

    Don’t
    Tinkerer don’t be ashamed of being long winded, the knowledge is appreciated.
    You may be changing my mind here to the width of pad, I have always assumed the narrower the better unless you couldn’t stay afloat, down here in bama we have the most diverse soil conditions you could imagine, less than a mile from me is “flat woods gumbo” that you can sink to China in, less than 10 miles in the other direction is Sand Mountain, and here in my valley we have Chert pits, and everything from solid rock sticking out of the ground to low pasture land with topsoil, but I use the little td8 for everything, a lot that I need a big dozer for, so I assumed that the narrow pads would give the most “hook up” under most conditions, and give me the most out of a small dozer as far as pushing, not to mention compaction for driveway and pad work where I need to crunch chert rocks in

    Set the machine down so the rollers are on the links and then take a picture where a roller flange is directly over a track pin boss. The rollers in the photo don’t look that bad.

    Then there is another problem
    Those photos show a near new roller by flange and face.

    Incorrect but still IH idlers sitting too tall to the running gear
    Close enough to appear correct but still wrong. Sitting on solid surface idler should not be carrying weight rails should not weight bear contact surface until the first roller.

    I would like to see a photo of the rest of the bottom rollers in relation to flanges and the track pin bosses. I think DMiller is correct but I'm interested in looking at the track frame as a whole.

    why does the inside of the roller surface show a contact pattern and the outside show none? or is it just me not seeing it right? the rollers should show an even contact pattern on the inside and the outside load carrying surfaces. maybe its there and i'm not seeing it

    That's what it looks like to me plus the rails are running hard towards that sides flange.
    Also looks like that roller is close to 100% worn.
    When you get to machine could you post pictures of front idler and mounts and back of blade show pins and mounts.
    Thanks

    No curvature wear as typical to the roller faces, Flanges do not appear to have been 'Dressed' and are about correct height as I can see them.
