Info on D-2 carry-all scraper

I just picked up a Murray (Modesto, Ca.) model D-2 carry-all scraper. it appeares to be about two yard capacity, dual spool hydralics required. I guess that it is sized just right for a D2 Cat. Original color looks to be orange.

They made few diff sizes the littles was D2 size I for get the model number the bigger was D4 size and painted orange but seldom see them orange most have been painted saftey yellow They look like a LeT and for years paid LeT for patent rights. The problem with them is they were built for high volume low presure hyd system. and unless it has been converted to high presure the seals and packing will leak bad or blowout .
Most of the time they take out the plunger with the old leather cups and machine a new head that take couple O rings to solve the problem
Ed Akin in placerville just retored one behing his Dads orig D2. The D2 size is rarer and a great show piece
