The real way to move dirt

Josh,

Looks like it would not take long to load the scrapers with three 10s pushing! It also looks like potato dirt, such that, you would not tear the floor out of the bowl.

Thanks for posting. I want to get up to see your collection one of these days.

Jan,
It took about 20-30 seconds to load and the dirt was pretty good. It had a little cobble in it. The cutting edges probably were smoking a little.

You are more than welcome to come by anytime you like. You may get to come by default because I offered to have the chapter sixteen meeting here next time, but haven't heard back from anyone yet on a date.

Talk to you soon, Josh

Hi, Joshstephenson.
Thanks for sharing. Nice subject matter. Now if 3 x D10N's or R's can give a 20-30-second load time in those conditions, think what 3 x REAL D10's, the 84W's, could do. LOL.

Do you know or know of a gentleman down your way named Jerry Dalrymple? If he is not already involved in Chapter 16, he may be interested. If you don't know of him, let me know the details of your next meeting or your contact details and I will pass them on.

I sat him on a cable Cat-n-can at Tulare last April and he looked like a kitten with a longer piece of string or maybe a cat full of canaries.

Just my 0.02.

Josh,

Thanks for the invite. I saw Myrna at the Sat. annual meeting of ACSEM and asked that your hosting us wait until July or after as I will be out of the country until then starting next month. If they settle on something earlier, that is fine. I'll make my way up there eventually. Glad you joined the group.-Jan

cool pictures!
i dont know so much about working with scrapers so my question:
can it not be done with just 2 of these d10n 's?? or is this box too big and realy need this 3rd pusher?

Hi, Marcoten.
It is not NECESSARY to have 3 x D10's pushing to load a 660 or a 651 but it helps. In normal working conditions, it would be most companies policy to have two dozers pushing with three on odd occasions if they were all free at the time.

A D9G will load a 660 but it would be slow and you would not get the FULL capacity of the bowl. The more power and traction you can get assisting the scraper to load, the quicker it will be able to load and the tighter the material will be packed into the bowl. It is this tighter packing of the material that contibutes to FULL loads and the quicker this can be achieved, the more production will be achieved from each scraper. It was recognised among many contractors that a single D9G was adequate pushing scrapers up to about 631's, 641's and above had many contractors trying to have two dozers available for each scraper. The 76X and 84W D10's were the first dozers that were truly capable of getting close to maximum loads on 651's and above in quick times with only one dozer for each scraper. Sadly, the 76X D10 only came out in 1978, the same year that Cat stopped producing the 660's and 666's.

It was the need for more grunt that led to the DD9G's being developed as a way of putting more push power behind a scraper with only one operator and eliminating the delay that usually happens in getting the second push cat in place and pushing.

Just my 0.02.

Great photos. I'd like to see a couple of sets of DD9G's behind 'em. That'd be the only thing better.

Those scrapers have to be tough to handle it. That's when they made 'em to last.

Here are a few DD9 pictures I've saved over the years.
