how many tons of rock in a cubic yard
Volcanic boulders that are the same sizes are about half of the weight. A cy of dirt or mulch is 1 scoop on our skidloader. On rock there is a little over 1 1/2 ton in a cubic yard, so a cy of rock is 2 scoops on our skidloader. 1 skidloader bucket is about 3/4 ton of rock.
