D4K2 blade lift hydraulic capacity

I need to temporarily convert my D4K into a D4k-lift. ;) My question is how much additional weight beyond the blade itself, can the lift hydraulics handle? I guess I could ask are there any accessories (such as a root rake) that can be used on the blade and how much do those weigh?

I have about 2 tons of concrete bags to move and I'm hoping it will be more than one at a time. :)

I don't know if cat speced a force, but think about it if you've ever come up under a stump with that thing and got with it, I'm pretty sure it's more than two tons :) if you strap two tons of something to the front though it's going to wallow along pretty crudely. Keep that in mind if you have any soft conditions.

Well I think the whole 2 tons would be a bit much. You're right that it would be pretty unstable. I was thinking more along the 500 to 600 lbs range. Also adding a few hundred pounds on the rippers in the back to balance things a bit

I think clay is around 3000lbs./yard. Seems when pushing in a stall the blade on dozers easily lifts up to keep pushing. Never looked the blade capacity up but sure it's more than 1 yard. I'd think you could easily lift a ton or more, maybe 1 1/2 tons.
My 931B loader can lift about 4000lbs with the 4 in 1 bucket on. Pretty light on the back end with no counterweight when lifting a heaped bucket but lighter material isn't a problem. A dozer is mostly limited by hyd. capacity with the lift cylinders retracting rather than extending. With a ripper on it you should be fine and probably won't need extra counterweight. Your machine might have a longer track frame too.

How far to you have to move these bags and over what type of terrain? I've moved a lot more than two tons of concrete bags in a wheel barrow for a lot less money than it would take to modify a dozer blade to handle pallets. A couple of days of rental on a fork lift or skid steer would be less than the design, materials and labor for what you are proposing.

Well it's hard to describe but about half a mile and up a hill so steep my F350 can't make it. I would say a wheel barrow, fork lift, or skid steer is out. Haha.
My Plan is liberal application of Uni-strut, plywood and strapping.

In 1995 at ESL IL UE Headquarters I was issued a job to help recover a crane near the Rush Island Power Station, REALLY Sketchy directions that ended at a gate where I was to radio to the line crew I had arrived. Sat there ten minutes then heard the 1150 Case, cabled onto the 4x4 ton single wheel and away we went thru a swamp then up a slope I feared the engine would starve for oil.

Crane was a older grove truck chassis rig, on its side with outrigger buried in a hole. Had to cut away the mast and two of four outriggers, then they dragged that carcass then my service truck back out.

Go talk to a logging crew working a yarder. That's everyday work for them, except they are pulling and pushing in 100K or more. A few sacks of cement would be light work.
