Lawn Lad, I moved them with the skid loader posted above...
It's close to a Bobcat 883-S300
Those block were guess by the cubic area of concrete, some of them felt heavier than others, and I got 2 that were a lot fresher and made the loader wobblly.
Chuck, those pics are very similar to Uni-Lok blocks.. The place this bin it at, has about 10 of the ones like in the pic, and 4--2x2x4 ones, those blocks are perfect compared to the ones I got.
The owner didn't even know that those blocks are even the stuff I had to move exsisted. After I was done he said we could have them...So after we get some salt in there (Friday), we might add thoe blocks to it, if I want more salt.
You can see some of them in the second pic...
