I have been lurking around these forums for a long time and Finally have a question to ask. How much fuel does a 657 use in a day. More specifically what would a group of say five or six 657s burn a day. In very sandy ground? Thanks
Which model of 657.? Early (no letter suffix), B, E, or G.? Engines Tier 4-rated with all the emissions fruit or earlier models without.?
a G would be 26 t0 34 gph at med. load
It is in California so I would assume Tier-4, whether they are repowers or newer models I don't know. Its a wet hose fuel bid and all it said was 657.
Soft & sandy underfoot, especially if it's damp, I would say would most likely fall into the High Load Factor category which would be in the range of 35-43 gall/hr per machine.
Given the escalating fuel prices these days, its becoming more and more of a no-brainer to move away from these traditional twin engine scrapers, and go with a fleet of pull-pan scrapers pulled behind ADT's. Using 1 engine at 18GPH with the same material capacity, instead of the 26+GPH listed above will make a huge difference on the project profits.
Thank you for the help. Looking at this from the supplying the fuel end, not (unfortunately) the operating end. I've always found scrapers fascinating.
No knowing what an ADT was. Looked it up and wondering why? You have extra tyres to wear out, you have more drive train parts to wear out. It has two points of bending to wear out. I am failing to see the general advantage.
Old motor scrapers have 4 tyres that bear the weight of the load and all follow in the same path, causing haul roads to pump out with bumps. The ADT/moxy truck & scraper combination spreads out the weight of the load, and the row of 4 tyres on the scraper bear the majority of the weight of the load and evenly compact the haul roads and fill zone area as an asset - not a liability. You can also use your existing moxy fleet drivers to easier become scraper operators, as they are familiar with the cab and operation of a truck, rather than a different rough-riding machine.

Pull pans work in clean material but they dont hold up in a lot of the conditions around here There are a few outfits with pans but 5 times as many scrapers here cause they work in any condition
Pull pans are great when you have a lot of real estate to work with. They shine for wide area cuts and fills with no rocks. But the pulling units are not designed for that kind of use. Ag tractors, Quads, ADTs. 5000 hours and they are a basket case. 5K hours on a self propelled scraper, if properly maintained, is well broke in.
G would be like 35 at med
