When I was 16 in the later 1960's my cousin and I buried "garbage" barrels at a remote wooded site in MN which came from a plant in Minnapolis. We used a D7 and a D8 with pull scrapers. Incidently the site is now a super fund site and all fenced off. A week ago I located the scraper that I pulled with the D7 and bought it, recovering it from the forest it was parked in. The owner said he had not moved it in over 30 years. The tires still had air in them. I am attaching a couple of pictures. I know it is a LeTourneau built in the days before Cat made there own but do not remember the model. The serial plate is long gone from the back right corner. I'm sure somebody will be able to ID it from the photos. It is about 8 yds capacity give or take if I remember right. Hopefully before to long it will be connected to my 2U-D8.

Quite a find....and in remarkably good condition to..
The Model LS Letourneau was about 8.2 cu. yds struck and 11.0 heaped.

Darned good looking LeTourneau Scraper, and the tires are still inflated!!! Pulling this with your 2U should be a piece of cake for the 2U. Plenty of power there. Thanks for keeping the "Old Iron" moving and being a "Living historical museum" for the rest of us - - nice "eye candy"

Thanks guys. Your knowledge continues to impress me. I know you can't look it up that fast so your brain's must be in good shape. He has an old D7 that was setting with it. Not the same one I ran. Engine block is laying half buried in the ground, the head is rusted solid setting on the tracks, radiator is laying half growed into a tree, but the tracks are almost brand new. Ruined the crank he said. I tried to get a package deal but he wants to keep the 7 for a while yet. I think he is waiting for scrape prices to go back up.

Habit,

Just curious, did you ever have it upside down? -Jan

This thread brings back a question that I have been cusious about for years.

The mention of the capacity of a scraper is usually listed as, "Struck" and "Heaped". I am fairly sure I understand what "Heaped" means, like heaping full, but the word, "Struck" has me guessing. Help me know if I am wrong but does "Struck" mean something like just about level to the top?

I really would like to know if I am correct or if it means something else.

I'll thank you all in advance for the answer.

An Educated guess ,by the uneducated , Stuck would be level with the top of the sides .

According to the internet (and we all know it doesn't lie...), struck is the volume of the bucket minus appendages like cutting edges and whatnot, and heaped is when you "top it up" so that it's spilling over the sides. I thought it was the difference between the scraper filling itself, vs. the scraper being filled by an excavator. Not sure why I thought that but it just goes to show how I over-analyzed it...
Cheers,
Neil.

Hey Gang,

Know through the term Pay Load(or Bank Yards)in the mix and we can really get some different meanings out there. When the scraper is heaped at 11 cyd, how many Bank Yards in it? Now one has to figure the swell factor or fluff factor. Good discussion topic. I have a project going on right now where the engineer forgot to factor the difference between a Bank Yard and a Truck Yard. Big difference.-glen

No, I never did turn it over. It seems to me it would be hard to do with the back axles in the cut. We never cut any slopes though. Or do you mean is the bottom wore out. The bottom of the tub and the cutting edges all look like near new.

Hi, Folks.
As I understand it - and me being from DowNunder, I may have this all bass-ackwards and down side up - Struck capacity is water level and heaped is as much as you can get on it given normal spill slopes in loose material - not counting the huge lumps that may be sticking out of everywhere if you are working sticky clay or similar. Having said that, the struck and heaped capacities of scrapers in particular are going to vary quite a lot depending on how they were loaded. Especially with the larger scrapers, there can be quite a few tons difference between a full heaped bowl that was loaded while being push-loaded with one push-cat and the same-looking load when pushed by two or three tractors due to the compaction factor that occurs with more power being used to RAM the dirt into the bowl.

In short, these figures are only generalisations and can not take into account any variations in local conditions or operating methods.

Hi, Old-iron-habit.
NICE find and thanks for sharing. Your 2U should waltz away with that.

I think the earlier reference to turning it over was more about roll-overs than about maintenance. Those old LeTourneau scrapers acquired a nickname of "LeTurnover" due to the fact that the unwary sometimes found themselves dragging what might best be described as a 'boat anchor' 'cos they had not been paying attention and the scrapers wheels were no longer in contatc with Mother Earth the way they were designed to be. All that lift mechanism and spring assembly up so high tended to make them a little 'wobbly-booted'. Side-cutting batters was not one of their better 'things'.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.
