300 loader bucket

A 3' diameter rock is quite heavy. Volume of a sphere is V=4/3 times Pi times the radius cubed. A 3 foot diameter round rock has a volume of about 14 cubic feet. Stone varies quite a bit in weight per cubic foot, but granite or limestone is about 165-170 pounds per. So a 3 footer would most likely tip the scales at about 2400 lbs. the bigger 4 footer would be around 5700 lbs. I think you'll need a bigger tractor

Well, the tractor/loader performed without a problem with the River Rock.
Haven't tried any boulders yet, we're still searching for a cost effective source, cheap.
With a little practice I was able to get some pretty full loads in the bucket, only took about five hours total. Still have some arranging and black dirt work to do.
I'm trying to attach a picture to this post but I don't think it is going to work.
As far as the boulders go, I probably won't try to lift and place them so much as nudge them into place.

Terry is correct.. you will need a bigger tractor for the large boulders! I just got a JD 5105 with loader and it can lift over 2000 lbs. I have been moving good size boulders that have "bounced" my tractor a bit and these boulders are no where near 4ft size.. Your tires may even dig a hole trying to scoot those behemoths around... I am sure you will have fun trying though!

good luck..
