666 Scrapers (SoCal)
These machine's were common at one time in So Cal. Many contractors had large fleets of these. These machines in the right application could move a tremendous amount of material. Most were pushed by tandem D9G's & in later years single 76X D10's & tandem Komatsu D375A's. Company's that I know of were McCoy Const Co,Tutor Saliba,Ebenstiner Co.,C.A Rasmussen Inc, Kirst Const & Carver Corp. I never saw any 666B's, all were 666A'a (64H & 77F)
Must have been 40-50 around, although some were probabaly the same one's changing hands. Most of these were retired or sold off by the late 1980's. I know Tutor Saliba held on to theirs untill 2000 & sold them at a Ritchie Bros sale in Perris Ca. I think Dennis McCoy and sons had the last fleet running in SoCal, I saw them in 2003,don't know where they went to. I think Independant Const in Corcord Ca still has some active 666B's if anyone can confirm that chime in.
As a side note, many of these machines were seperated & hooked to bege drag scrapers.
For those of you that don't know the term "SoCal" it's a slang for Southern California.
