| David Brown posted Awesome view one rig broke. It took this many to push it up the hill. [I assume that is an attempt at humor. Some comments indicate that this is a service lineup at the end of the day for refueling and lubing.] |

| Big Machine posted Great team ! |
These are coupled in pairs. They start with the front unit digging dirt and the rear unit pushing. When the front is full, the rear starts digging and the front pulls. This screenshot catches the rear unit lowering its pan for its turn to load. Each unit has an engine in the rear as well as in the front. So they are digging with the horsepower of four engines and the traction of eight wheels.

| 3:49 video @ 1:33 How many scrapers can you count in this LB3 Enterprises convoy? By my calculations there's around 1000 tons being moved in the space of this video. |
I wonder how many pieces there were when it was disassembled for transport to another work site. Operating that from a cab on the second unit must have been challenging.

A reminder that cables had to be used before hydraulics were developed. Actually, hydraulics may have been developed, but LeTourneau refused to use them for a long time.

Oldan Grumpi: A slightly newer version of these were still in use in Alberta, Canada in the late ‘50s. A crude predecessor of the Cat DW 21, if you will. The electric controls were sketchy as hell, and one oft repeated local story is related to the building of the Dunvegan hill on the Peace River in northern Alberta. The hill was severely steep (at least 1:1), and they were loading with a D9 pushing. The guys electric steering crapped out in the pit, which was at the very top of the hill, and the push Cat unwittingly shoved him right out over the brink of the hill. The poor bugger got the ride of his life; he tripped the emergency scraper drop (which no doubt saved his life) and in doing so carved a groove down the hill that was visible for decades. Apparently scrub trees and stumps were coming right over the tractor by the time he got to the bottom. |

| NZ Contractor magazine posted Sneak preview of our April 2024 classic machine profile- of the legendary LeTourneau Model C Tournapull Caption: Scanned from an original July 1940 specification sheet from my collection, this is the first iteration of the ‘standard’ model C Tournapull with trailing model LS Carryall. As you can see, it is very basic with very few creature comforts other than lights. In the event of a hitch breakage, that sheave block on the scraper push bean is coming right down on top of your head! [There were several comments indicating this was not just hard to drive, but dangerous.]Mike Burton: Super Cs moved a lot of dirt, in L A they use to push them with H D 19s but the goosenecks were weak and they lived up to their other name “ Widow maker “ Ian Clements: Widow makers they came around under the goose neck when steering failed they ended up putting chains on either side to prevent this happening. |

| NZ Contractor magazine posted Sneak preview of our April 2024 classic machine profile- of the legendary LeTourneau Model C Tournapull Caption: Beautiful study of a Super C Tournapull with LP scraper self-loading in sand. Not all C Tournapulls delivered after 1941 had the half cab as can be seen here. It took a skilled operator to run a Tournapull in this kind of material and this fellow is at the top of his game! Normand Dupuis: The technique I heard described for sandy conditions was "pumping"! It was a series of short dips of the bowl like gulping. That was meant to lessen the effects of losing traction in loose material instead of a long period of continuous scraping. It was taught in the US ARMY Engineer Crawler Tractor Operator Course I was given in 1971, although the ARMY had switched over to Cat 830M and Clark MICHIGAN wheeled scrapers almost exclusively in the late 60s/early70s. Jack Elliott: I've had a lot to do with tracked and wheeled scrapers ,I think if you pump load you ll end up with a mess I almost always put the stinger,or middle cutting edge down 75mm ,3inches once you ve cut over the borrow area one time just keep loading the raised offcuts. Sonny Moorehead: It was a wonderful machine, but a little tricky at times it was very powerful. It was hard on your fingers all the buttons. Pete Craddock: I ran one in 72, it steered with an electric switch plus a five speed manual transmission. Neil Skarloken: Pete Craddock In 69 l ran a C-Pull , instead of a steering wheel it had a brass bar to hang on to with series of electric switches in the dash , electric motors instead hydraulics, always had a box of ignition points. |

| NZ Contractor magazine posted Sneak preview of our April 2024 classic machine profile- of the legendary LeTourneau Model C Tournapull Caption: Scanned from a rare colour 35mm slide, this is an Australian manufactured Super C Tournapull with LP scraper going about its work. Production of the C Tournapull commenced in 1946 at LeTourneau’s newly established facility in Rydalmere, NSW and hundreds were built, some coming to New Zealand. Geoff Smith: There was 7,142 C models produced. No idea how many were manufactured at Rydalmere. |

| Jacob Moneymaker posted I’m trying to get this old DW10 back going. It’s my first cable scraper. I’m trying to figure out how the crowd operates. I’m assuming that after the door opens the crowd activates if you keep holding the lever? I’m pretty sure the winch needs adjusting or the frictions replaced because the up/down works like a charm but the second drum is very weak. Marty Casey: You're right once the apron reaches top then the tail pushes dirt out but don't push all the way to end unless you want to change cable. John Bell: apron goes up and slider in tube hits the stop then tailgate comes forward Sam Walker: Yes when the apron gets to the top the ejector will start moving forward. [Another comment reinforces that the "door" is the apron and the "crowd" is the ejector.] Marshall Dearman: I operated A DW 15 Back in 1961 was young then, they were fast, I enjoyed the heck out of it! Operated DW 20, 21,31, 41,51, 666. Enjoyed the speed. Am 85 now and have had 3 or 4 back operations, Ha. It gave me A life to remember, ever time my back hurts. Erik Myers: Marshall Dearman you should have ran the old euclids ts-14s24 TS 24 ts32 ts-18 they were very kind to the back haha |

Couldn't keep transmissions in the rearend, as they were constantly going bad. Just too light for the job at hand. The TS-24 was a descent machine though, and I've never had anything bad to say about that one. |

They were popular-in the day but just give me an old Fiat Allis 260-B. Run circles around those green machines. To summarize many of the comments: The Detroit Diesel engine (2 471s, I think) was loud and high pitched. The transmission kept breaking. The seat had a bad (none?) suspension. They could run on a slope steeper than the Cat 21 could handle.] |

It is just a second Tub attached to the back if the First one! Rear engines were 471 Detroit Diesels. Hugues Danjou: For TEREX machine the name of TS means 2 engine one in front and one in back with 2 transmission , exemple TS24 in front 1 12v71 with CLBT 5960 and for back 1 6/71 with MT 600 , it was difficult to synchronize both machine set .The last machine have worked on the site of CARMAUX in France during the year 81 to 85 if i'm remembering well .The company was BALLOT. Clarence Lokken: Better known as the Screaming Jimmy , and Green Leaker . Peter Harris: I think that is TS14. The 24 had power down apron,this looks to be wire rope up and gravity,plus load down. |

Engine-- same as DW20/21 only natural aspirated but lots more power 10 speed transmission as opposed to the Dw10 5 speed, foot operated brake pedal, ( DW10 had hand lever brake) nicer seat higher top speed and capability of handily a larger scraper. I've run both of them. Both were rude and crude, neither offering nor accepting operator comforts.

| NZ Contractor magazine posted Sneak preview of our June 2024 classic machine profile- of the Curtiss-Wright CW27&28 scrapers Caption: Photographed during smoko break on the Auckland Motorway job in the early 1960s, this Curtiss-Wright CW-28 has had its Roto-Gear steering removed and replaced with a more conventional steering system using a couple of hydraulic cylinders and some multiplier linkage a-la Caterpillar, making it far more reliable. This CW-28 is NZ Roadmakers’ fleet number 6 Ken O'Connor: What was the original steering system like? Donald Ewen: Ken O'Connor very jerky. When travelling empty after about 45 degrees of turn the inside back wheel of the scraper would lift off the ground when the steering was operate . It had a steering wheel which operated a valve, on or off . There was a Curtiss Wright, aAllis Chalmers 160 ?, and a LeTourneau Westinghouse Model D at a demonstration for northland contractors on a roading job site at Kaiwaka. None of the operators liked the steering on the CW , they liked the Allis steering , but the Model D was the preferred machine for best performance.

Caption: Pictured in better times is a genuine Wooldridge ‘Terra-Cobra’ motor scraper, one of the flagship machines in the Wooldridge range of equipment before Curtiss-Wright took over, and a predecessor of the CW-27.
As can be seen, it is not particularly pretty and is all cable controlled.
Dennis Dick: Todd Lake and people wonder why I have back problems and have to have my left arm joint replace

| Ad Gevers posted Cat D9E-DW21 William Alan Tuson: Great cables scraper !! Eugene Urchyshyn: This is not a DW -21 |
This caught my eye because the load is so big. Some comments agree.

| Machine World posted Stuart Busby: A sideboarded DW-20! Chris Hughes: This is what they had in the 1950's- notice the front axle steering. Patrick Hayes: The box should be only a few inches of the ground. Tom Corcoran Sr.: Some had rear engines also. Geoff Robb: Bit late to be checking tyre pressure [Some comments indicate this was cable operated.] |

Bob Weight: Cut and fill ,Good old days. Tony Scott: Good old days for sure. Not a satellite assisted machine to be seen. Bob Weight: Tony Scott Just talent , my friend Tony Scott: Bob Weight Plus a few pegs and a string line. |

| Brad Barnish posted If we ain't spilling, we ain't billing Brad Barnish: All you efficiency experts have no clue about my cycles, the extra isn't costing me, I'm gaining an extra yard per carry , so 120 yards / shift...go troll someone who doesn't have their ducks in a row. Brad Barnish: Brian McBride, if I can get it heaped ,and spilling, I am filling all the voids , and what all of you experts don't understand is that it's subjective to the material being loaded, I would never do this in clay or cobble, but with sand , I'm all about it, especially when the load time is under 15 seconds, and you guys keep fuel shaming me ? I guarantee there's no excess of fuel being wasted, in the sand this scraper was probably 60% throttle front and 75% rear. And what my experts are overlooking is the picture itself, do you see a bunch of spill on the ground between the center of the can and the rear tire ? The answer is no , and this was captured just a second before the hitch popped and he got gone . But if course all the critics know better than the guy who is actually there. [There are lots of comments on his post. Of note, Brad doesn't have side boards on this pan because it is a rental unit. They do extend the ones they own.] |

| NZ Contractor magazine posted Feast & McJorrow hard at work in the Wharerata Hills in the mid-1960s. In the photo are an early Caterpillar D8H-46A with hydraulic 8S blade and No.8 ripper, Euclid TC-12 and two Euclid TS-24s. Feast and McJorrow were a real class act in their day and did not shy away from big machinery to get the job done. Peter Ferguson: Euclid and Caterpillar together must have moved at least half of the world. Garry Alley: Peter Ferguson Allis Chalmers was the front runner for years and years. Carl Smith: Allen Cameron , 1st TC-12 into the country 1960, followed later by a Terex 82-40 & 82-50. [Some comments indicate that a TC-12 could outpush a D9. It used a Detroit Motor.] Chris Evans: 235HP D8H |

| Historical Construction Equipment Association posted By Thomas Berry, Archivist, Historical Construction Equipment Association Excavation for the Ludington Pumped Storage Plant on the shore of Lake Michigan just south of Ludington, Michigan, in the late 1960s and early 1970s, was one of the largest all-scraper jobs on record. The work involved removing 48,000,000 cubic yards of sandy material from a bowl 2.5 miles long and, at its maximum, 110 feet deep and a mile wide, and from the foundations for the power plant and penstocks. The TS-24 motor scraper, first developed by the Euclid Division of General Motors in 1957 and continued by Terex until 1986, was an impressive machine. Its rated capacity was 40 tons, or 24 cubic yards struck and 32 heaped, and it was powered by two Detroit diesels, one in the tractor and another on the scraper. As of early 1969, the engines totaled 605 flywheel horsepower, and the machine weighed 91,000 pounds empty. Now imagine 81 of these big scrapers massed on a single project. Joint venture excavation subcontractor Walsh-Canonie Companies selected this enormous fleet to do most of the digging and organized it into as many as 15 different spreads working simultaneously. Each machine carried 22 cubic yards in place, compacted, adding up to 2,222 yards per scraper per day working two ten-hour shifts. Assisted by nine single-engine S-24s of like capacity for utility work, production reached 180,000 cubic yards per day. Project manager Jack DeSart said, “Our choice was based on capacity in relation to production schedules, terrain characteristics, various soil conditions, grades to be negotiated, and length of haul routes.” The hauls were up to 1,500 feet each way, with grades of up to ten percent out of the basin. Work started in the summer of 1968, and was on schedule as of December 1970. Completion on or ahead of the October 1973, deadline was expected.

They built a temporary bridge over US31 for the machines to haul from one side to the other. I think they lined the inside with clay. I don’t remember how, or where the clay came from though. I think that was the biggest project Walsh/Canonie had ever done. They were based near Benton Harbor. [Another comment said the borrow pit for the clay was about two miles away.] |

| Big Engine posted Nice! The Terex motor scraper Peter Reed: There'll be a nice pair of Jimmy's in that. And it'll sound amazing too... Jim Macdonald: Peter Reed TS24.Push/Pull. Had them in the UK in the 60.s. Used to break the chassis in front of the rear power pack. Richards from Warrington drove them from England to Scotland on the road in the mid 60’s and worked them on the A74 when I was a diesel fitter in Scotland. They were muck shifting a long time before the Twin power Cats and 333fT Wabco’s were competing. The Terex TS24 pioneered Twin Power and Push Pull Scrapers and we used to push them with the twin engined Terex oscillating shaft Dozer when the going was tough. |

| NZ Contractor magazine posted Sneak preview of our December machine profile- on the Cat 613 elevating scraper. Caption: This image shows how simple the controls on an early 613 really were. In those heady pre-ROPS days, the only form of comfort offered to the operator was the Milsco air suspension seat, and note the lack of a seat belt! Ken O'Connor: If the machine is running don’t grab the steering wheel on the way up. Kenneth Siemens: The only thing wrong with the 613 was the 3208 engine they had if they would of had a inline 6 cylinder that why The John Deere 762 where better. Roger Horner: Kenneth Siemens I was a dealer field text. The little JD scraper was a good machine The 613 way outsold them. At Cat we had 3208s in 613,225 and generators. We really didn’t have that many problems with them. I heard complaints but when we invested it was all most always customer issues. 613 issues for us were mostly brakes. Next was elevator chains. Charles Talbert: I've operated all these machines extensively. Most would disagree for numerous reasons, but the IH 412 was literally my favorite in this size class. Power to spare and the easiest to maintain and work on by far. [There are lots of comments about how rough riding they were. The comments were mixed as whether or not they had a seat belt.] |

Items of note are the engine side covers, and the added rear view mirror. Photo taken 1975. Catskill Pete: Nice! A windscreen wiper! They thought of everything. Jim Hopkinson: Over 6000 hours on 623b. Good all-round machine just bloody hot. Jandals shorts and hat was the uniform of the day. Ruger Kuhntovah: Jim Hopkinson Yeah big difference between a 613 and a 623, absolutely hated 613's, rough riding horrible little buggers! 623"s were a lovely machine to operate, yeah I had the same uniform!

| NZ Contractor magazine posted Sneak preview of our December machine profile- on the Cat 613 elevating scraper. Caption: A further revision to the 613 in 1993 resulted in the 613C-II. This was quite a different animal to previous versions, and featured a completely redesigned operator’s cab plus another new engine – the Cat 3116T. Why Caterpillar didn’t call this version of the machine the 613D is unknown, as it was quite different. |
Dan Shepherd posted two photos with the comment: "Got the 1974 613 all painted up and ready to move more dirt this summer. Really a nice outfit for us being a farmer to do dirt work with. Yep I know it's not the big boys I see on this page but does what we need it to do."

NZ Contractor magazine: Ken O'Connor - It depends on the scale of the earthworks you wish to perform - tidy up work doesn’t really require a larger dedicated machine, but land shaping, contouring etc, would benefit from a proper scraper.

| Thomas Kagerbauer posted Caterpillar 633C since 1975 in the same gravelpit. Owner says round about 50.000hr on it. And still running 4 days a week. Ron Campbell: That is a 633 elevating scraper. 631 tractor but a elevating bowl with the whole bowl bottom opening up to dump. Rick Bishop: I've never seen a 633 c , run 631c& d, peeled the bottom up on a 631 d, rolled up like a sardine can, double pushing with D8&D9 Ron Campbell: Rick Bishop we shoved them with a D11 and no bowl problems. 19 seconds to get 18 M3. Roger Horner: Yes those were cool machines. As a cat dealership field mechanic the story was a little different in the 70s and 80s Main frame cracks on D9G was common. We lost our minds on D8 and D9 combustion in the radiator calls. Bearing failure on all the high speed engines. We were dancing in the street when a D346 or D348 hit 10,000 hours. Never had to worry about that on D 343 as they never had a chance to wear it as they all blew up on over speed or over heat. All 12 and 14s were scrapped with broken mani frames. Now I just plug my computer in and change the bad sensor. I do miss the good old days ! Harry Wulff: Yep good in loose dirt but when clay especially wet had trouble dumping the load as the floor and ejector were one peace floor would slide up towards back of scraper and it would stick so had to find rough ground and hopefully it would loosen up [A couple of comments indicate that the D could not dig as well as the C.] |

Larry Freeman: Been there done that so many times over the years. 637’s , 657’s and 666B scrapers. While working for dealership in Southern California. Peter Woodburn: thought the e model had integrated ac. Kayne Hayward: Peter almost all but a few scoops I've been in, in Australia have roof mounted ones because they handle the heat better than factory. Edgar Pearson: I helped change the pins and bushings on a 631 E but it was in a shop with an over head hoist. Denny Jamison: I rember back in 1970 we had only two acel trailers so the 31 s had to torn down and hauled a half on each trailer. Gavin Handley: The trick is to put a bit of downward pressure with the bowl when setting up the stands....that way it unloads the front tyres a little so it does'nt "pop" up when you seperate. |

K-Tec Earthmovers posted two photos with the comment:
66 yards, one tractor.The K-Tec 1233 Train doubles up efficiency by pulling two 1233 scrapers with a single power unit and one operator.On job sites with longer cut-zone and haul road areas, the K-Tec 1233 Train provides impressive production performance at the end of the day. This configuration has an added advantage since it can split into singles on your job site as conditions change.
[It is interesting how ag tractors have become big enough that they are showing up in more and more construction jobs.]

| Beau Forchini posted Are 641s considered rare? Only one I’ve seen, sits in the back of the yard. Jim McIntosh: There was a time that they were king of the mountain in highway construction. Slam Dunk: Jim McIntosh, haul roads and diversion ditches too. Chris Evans: Here's a quick 600 series lesson. The 641/651/657 all introduced in 1962 shared the same tractor . 641 was 28 yards struck/ 38 yards heaped. The 651 was 32 yards stuck/44 yards heaped. The 657 was same capacity as 651. The 641 outsold the 651 until 1970, then the 651 outsold the 641. Some years they would build around (20) 641's & (150) 651's. All machines were upgraded to "B" series in 1969, the 641B lasted until 1982, the 651B/657B were upgraded to " E in 1983/84 , the 651E lasted until 2005. When the "G " series was introduced ,only the 657 continued (651 was discontinued) as it outsold the 651 a wide margin. Happily due to renewed interest the 651 was reintroduced in 2021, hopefully it survives. Rocky Ungaro: Watched a 575 Komatsu fold a 651 up like an envelope in Las Vegas in the nineties hard ground and a 300,000lbs plus bull dozer not good combination. [The 575 must be a bulldozer and it was the pusher.] They used those 575’s for ripping caliche. An amazing machine. Was extremely powerful. Wouldn’t want to pay it’s fuel bill. Joe Bromley: Rocky Ungaro. Only about 2L a minute! Then common sense prevailed and drill and blast was used! Not cheap when you get about 5hrs out of a ripper boot! Allen Cameron: They are getting more rare ever year People are having to part some of them out to keep the rest going Cat quit supporting a lot of the parts for them. Lex Lassman: That's a good load with the added sideboards. |

| Dabancens Bruno commented on Beau's post Some models are more or less rare and this model is very rare because it's the first series of production 1962 1963 the fixing of cylinders of body are triangular and if it was possible to see the back it would be possible to see the rollers of ejector; the fender guards are special to the model 641 on the other series are the same for 651 657. |

| NZ Contractor magazine posted Classic Machine pictures from our archives- this photo accompanied the Euclid big single engine scrapers profile in our August 2018 magazine. Tony Fryer: I once worked with of a fleet of 72 of these beasts pulling bottom dump wagons, average load was around 120 tons and they were overtaking the road going Fiat trucks on the longer hauls, terrifying the Fiat drivers as the trailer wheels were wider than the tractor and would take out the truck wing mirrors! Alan Engnes: Always loved the big gals(666's) . A triple 6 was nothing but a 660 with a rear engine. Always considered them the easiest scraper to work on of all Cat's scrapers. To bad they've about became extinct. Not many around anymore. Buster Holt: D346 V8 ,be about 500hp in that early model 660,then later they went 550hp,early engines were 90 degree V8’s and known as the RM180 ,then later became 60 degree V8. |

| Roy Morey posted Another dream machine from the cat archives. I reakon you would take most of the back 40 to turn the thing around. [According to some comments, Cat was trying to emulate a Euclid design. And there were several comments saying there would be alot of welding because there would be a lot of cracks in the frame.] |
This strikes me as a more reasonable what to do two pans. But I think one would have to make sure the rear is not pushing too hard when turned at a sharp angle.

This is a Cat triple built by Peter Kewitt for a large contract in California (I think) Ben Clark: I believe it was operated by kewitt but mainly designed and built by Buster Peterson of California. Peter Drouin: Ben Clark yeah it's in the Peterson History book. They built it because of the Letoureau monster. There is even a picture they roaded it to job in San Leandro. They were all built for the California Aqueduct. Chris Evans: Brian Drinnan The photo is 1964/65, this was about 5 years before push pull was introduced. Gary Pinkston: There were two doubles and one triple set of 657 twin engine scrapers on the California aqueduct. I was the technical engineer with caterpillar on the project. Actual story the rear scraper came disconnected and went off thru the countryside at about 5 mph. Had to go get it with a field truck. Any more photos? Reo D Wright: years ago I worked off and on with a fellow who ran the 3 x657 we all thought he was full of BS till he brought photo albums to work. |

Calin Finney: I guess the first terex ts24 12v71 Detroit diesel up the front and a 671 Detroit diesel up the back the second terex ts24 could be a 12v71 Detroit diesel up the front and a 671 Detroit diesel up the back and the third terex could have a 6110 Detroit diesel up the front and maybe a 671 Detroit diesel up the back do you think I’m right guys ❤️🤩🥰😍😉

| Big Machine posted Looks nice! TEREX S-24B, Scrapper |
 |
| Big Machine posted Cool! The Euclid/Terex S-24 scraper Todd Welty: Spent a lot of time on those scrapers. They sure were low on power. The guys running Cats DW21s could run rings around you. Kelly Willcuts: Don't see no rear engine. We had the TS-24. V-12 in front and 6 cylinder in back. |

 |
| Big Machine posted Really big ACCO dozer! 💪 Bob Lamky: That engine looks like a toy in the dozer. Doug Berry: Bob Lamky twin CAT engines horizontally opposed. Ron Bohm: The same Cat Motor as in the early 641 and 660 at most 500hp not much for that sized machine. [That is why the information that it had two engines is so important.] |

Before Scrappers Were Developed

| MWRD posted A steam scraper removing topsoil in an area between Montrose and Lawrence Avenues on May 21, 1904. The Sanitary District of Chicago (now the MWRD) straightened and enlarged a portion of the North Branch of the Chicago River at the beginning of the 20th century to improve drainage and reduce flooding. The original river was a relatively small, curved and meandering stream between Lawrence Ave and Belmont Ave. By the end of the project, some portions of the river were widened and deepened, and other areas were filled in and replaced by a completely new channel. |

| MWRD posted A steam scraper removes topsoil in an area between Montrose and Lawrence Avenues on May 21, 1904. Bruce Vee: There's an elevating grader being towed by this traction engine. The upper end of the conveyor is visible just above the front wheel of the machine. The horse drawn wagon is most likely a belly dump wagon receiving the scraped overburden. |

This is the kind of video that I don't like: a lot of short clips. But it is an interesting subject.
