Dredge Crossing the Grey River September, 2012
Very cool dozer!
Probably one of the prettiest dozers ever made!..such a nice machine!..
Wonder where in the hell they find parts
Back when equipment was simple, reliable, and just worked.
Fantastic video
looks great in red
used work on1 of these that worked in a land fill years ago when i was a Heavy equipment mechanic
I hear its being recommissioned ..work has started
You guys look silly
That a pretty good size dredge
Thank you so much for showing this. What a Beautiful old girl. The Tracks look big (newer) So has the unders been turned. The ( RED) with strobes was in a Forest Fire surplus. Building the stream bed back, WOW, great work my friend.
Some of these Dozers look tiny compared with the modern D9’s and D10’s and even more impressive are the massive Komatsu brands. What exciting times, I’d work there, now where did I put my metal detector? LoL
Wonder if any nuggets larges ones makes it through to the tailings? I understand the need for restoration to pre dredge condition but when you think of the tailings are halfway being washed and graded for the aggregate used in construction.
A wonderful piece of technology that has been around for decades, and provided their is enough pay dirt can keep going for decades more.

Excelente vídeo. Mi padre tiene un td40b pero hay una diferencia entre los rodillos superiores de la oruga. Veo que su maquina tiene soporte o agarre doble en dichos rodillos superiores. El de mi padre usa los rodillos de un solo soporte. Esa es una excelente máquina pesa 67700kg con kta19. Se siguen fabricando en Polonia bajo el nombre de Dressta. Ahora es Dressta liugong comprada por china

Great looking dozer and good to see the IH badge on the front even though it's not designed by IH. They did however come out with a TD 30 in the early sixties. That was a badly designed machine that almost killed the reputation of IH. Since then they have not come out with a D8 sized machine.
Wrst Coast I assume?
That is a real machine , what a workhorse
SOU MUITO ADMIRADOR DESSAS MÁQUINAS, MARAVILHOSAS EM SEUS TRABALHO.
Rolls dozer full fast and barely barks to do it.👍
What a beautiful Dozer! I sure wish IH was still around, and was good competition for Caterpiller. They are awesome machines. Used to have a lot of fun on a little 175 IH track loader with a clam shell bucket!!!
Intetnational harvester corporation famosa marca americana☺☺👍👍
How many yards will it push
Put money on the fact ur loseing gold in the current
Awesome machine. Dresser then Dressa Poland now nade in China . That one is beautiful.
Nice IHC!
What a beast. Love it!
Watch ya fingies .
what is the % of loss on one of these dredges
Some nightmare repairs shown.
Gosto muito de apreciar esses vídeos de tratores antigos,pra mim é muito legal.
If you paint those dredge buckets white and red it would look like a Disney ride...just kidding great video
I didn't even know IH made a TD40, and I'm an old IH guy that started out on old TD9s, TD14s, TD18As, TD 15s, TD20Bs, and TD24s. Awsome machine!!
I ran a BTD 20 for a while in the 1980's, that had a Rolls Royce engine, does yours have the same?
I also drove a BTD20 with a RR motor in the 70's. It was okay to operate, but the transmission let it down badly. They never used tapered roller bearing in the transmission so everything came loose all the time.
No music Thanks friend good job done
How many lbs does it weigh
When i was an apprentice i though a TD6 or 8 was big in the 60's
A real machine with international integrity
Good to see a woman working on it.
Nice vidja. We have a 1999 TD-15E Dresser, which says "Made in Poland" also, an older IHC TD 20E, with the old IHC V8 engine.
Nice tractor what part of the world was your footage shot when I was a kid my neighbours used to have old td14s and td 24s they used to start on half compression and petrol then switch over to diesel can you give me some specs please weight & hp just looking at her I'm guessing about the same size as a D8 thank you happy travels cheers
That machine was operating on the Grey river on the Westcoast of New Zealand. The operator "could" be Rex Gorrie. I know he did operate it for a while, can't actually see the operator clearly enough.
the sound is shit
PS thanks for posting this. its a beautiful and colourful piece of west coast history. A truly wonderful part of NZ.
Grey River Gold and Hansen (american co) were partners and built this in the late eighties. No one could foresee the gigantic totara and other native timber logs buried in the river shingles especially at the working depth and these were always causing huge problems and delays and sometimes the dredge was out of action more than it was digging. Bear in mind these logs and trees in the river bed are probably between 1000s and 100s of 1000s of years old. They would not break and just played havoc with the bucket chain despite its huge size. From memory, both companies went tits up due to the lack of production capability.
there are solutions to everything. They could have welded tungsten tip adaptors on the front of every 5th bucket and if they hit a tree , fit tungsten picks , cut through the tree , remove the picks and keep dredging again
@@heartobefelt yeah well you clearly have no idea about ancient NZ forest trees. These hardwood monsters are centuries old, massive in diameter, and practically indestructable. The dredge was not robust enough to touch them, you can see by the damage caused to the buckets and chain to see that considerable horsepower was moving these buckets and they crumple as if made of tin plate. This huge shock load is transferred through the chain to the gears and transmission components with devastating effect. Rest assured the operators of the dredge didnt give up easily, but theres only so much the dredge could endure before the maintenance costs quickly out paced the income. These guys were deadly serious about getting the gold out, they just didnt realize what a formidable thing these centuries old buried behemoths would be. The Grey river is one of the biggest west coast rivers in the south island and its massive flow over 1000s possibly millions of years, would wash huge areas of the mountains down to the sea, with all the materials being carried through giant gorges and then deposited in what are now vast river flats. This is where the gold is, but so is every thing else, trees included, that was in the water. The best dredge mining experts in the western world would all have been consulted prior to the inevitable closure of the operation. Sad, but thats the way things go when you think youve got the jizz on everything, and quickly find you didnt. Cheers
@@andygreen685 We use Tungsten picks to cut concrete , shale , and Australian hardwood when set up correctly. I doubt your Totara or Kauri would be worse than Australian trees , why do you think they are called Ironbark ? Its possible people will come back to it one day with a different approach. For a start , replacing electric drives with hydraulic drives would allow tuning of relief bypass valves to allow slippage when they hit timber and prevent damage to the buckets
@@heartobefelt You are right about the tree hardness (using the Janka hardness rating table - the higher the harder): Ironbark (depending on specific species): 14 - 16 Karri: 9 Totara 2.3 (I think it is actually classed as a sofwood based on its grain structure) However if they are Northern / Southern Rata, then they are similar to Ironbark: 14 - 16 And whilst tungsten is hard and durable, it is also very brittle and would probably chip off under the force - but I do like your thinking. Also what would make it hard to chew / cut through would be the trees being highly waterlogged - timber just sort-of splinters and goes to mash instead of cutting neatly and I can see that also being an issue clogging up the trommel. While I also like the idea with the hydraulics, you would have to be so careful that no hydraulic fluid would get into the water ways if (or more realistically when) a leak occurred from a split line, leaking connector or a popped seal.
1000ns and 1000ns of tons of clean gravel if ya had it down here in the states you could make millions with it.
