these old " iron veterans " were pioneering a new and developing coal industry in central queensland in australia 40 years ago. my late dad operated the D9G and later the D9H during his career in the coal industry.
i followed him into the industry and operated the differential steer D8N and D9L, late i would operate the newer D9R and D9T joystick control machines. i would have loved to have operated these old faithful dozers though.
love your videos.
Heres another example of how tough these tractors are. Our 9H, its been rebuilt quite a few times but still to this day she runs like a champ. Its funny because we just traded in our D9T because it had more downtime with computer issues then our D9H did with basic repairs.
Great video.... Brings back memories!!! Still the most bulletproof D9 Cat ever built!!!!!!
unless doing finish cut, steer with the tilt
I just got a new set of boots on my 10T today, now it pushes again, all our stuff is new except for our backup breakdown machines which are old and rusty but they have no shortage of guys willing to climb on. But in saying there old they are nowhere near as old as that D9, our spare dozer is a D10N. Wheel dozer 854G, grader 160G, wheel loader 992G, a lot of people wouldn't consider them old but for a mine site they are
that turbo sounds so sweet!
@tarheellax92 I'll have to get in with you on that. The old D9's are pretty rough. One company here purchased a new Komatsu WA800 and had so much electronic issues and downtime with it that within a couple years, got rid of it for a 992C.
Had to turn up the speakers for this one! Great video! Keep up the good work on the vintage gear!
Cant beat an old D9G or H! Hell Yeah!
@PAmining Yeah thats great. Somewhere buried in my channel I have a D9G engine I have an engine getting rebuilt for one of these dozers. Its a ways back in there though from last summer. Big engine!
Thanks for the update.
My Faveriote Dozer there could be,The G & H and the D8K
my father has 2 d9h's a d10n and a cat d11r.the d9s are awesome cant beetem, the d11 is crazy big of course you know that. he also has 5 pay hauler 250's or 350's(cant remember wich)and a volvo 480d excavator. all amazing equipment. thx for the memories,and awesome video.
@PAmining Totally agree. What can a modern D9T pull or push that the good old H cant? I love the sound the D9H's engine too. Thanks again
Love dozer videos man, keep em coming!!!
no. it just brings the rpms down. it works opposite the way it would in a car. it has no clutching effect. you hit the decelerator when changing gears. it saves on transmission. Some cowboys don't decelerate and its like taking your car and doing a neutral drop with the rpms at redline
@Giuste86 Those are the steering clutches, that's how you steer the tractor. The more you pull on one of those hand levers, the more the dozer will turn in that direction. If you pull the hand lever back all the way (basically until you can't pull no more) then it will engage the track brake and clutch and freeze the track up so the dozer can make a tight turn. Track brake pedals are also on the floor.
@PAmining Thanks, question answered :-)
when u pulled that lever on the left at 2:32 in the vid, what do them two levers do?
Thumbs Up for the cab ride
Question- If the dozer has a "decellorator", does it also act as a clutch when changing from forward- reverse? Also, why 2 brake pedals if they are not for steering like the older models? Hope my questions made sense....
Outstanding vids, appreciate youre knowledge of these old machines. Looking forward to more.
