Pry out the rock using a four-foot-long metal pry bar and a flat, small rock or a 6-by-6 wood scrap as a fulcrum. Insert your pry bar between the underside of the rock and over the fulcrum and slowly pry it out.
Use levers to pry out the rock. First, with a shovel, dig around the entire rock. Force an eight foot 2-by-4 inch board underneath the rock. Place a 4-by-4 inch block under the 2-by-4 inch board for your fulcrum.
Repeat on the opposite side of the rock. Raise the rock by pushing down on one of the 2-by-4 boards and drop a wood block into the hole. Do the same maneuver on the opposite 2-by-4 board. Repeat on each side until you can roll the large rock away using a lever.
Place three or four short iron pipes on the ground, lying parallel to each other. Then lay a plank across the pipes. Loaded onto the plank, a large rock glides easily, but you must continue to move the pipe farthest from you forward as you roll the rock along.
Pull out the rock using a come along or a ratcheting lever hoist. Do so by harnessing the cable end to the rock with four-inch nylon straps. Attach the other cable end to a sturdy object, such as a trailer hitch or a tree, and begin to crank.
Dig a trench around the rock with a shovel and attach a heavy chain around the rock. Then hook both ends of the chain to a truck's trailer hitch and pull the rock out as you drive your truck forward.
Use an old-fashioned rock sled to move the rock, but first you must roll or lift the rock onto the sled bed. Hoist a loose rock into the bed of a truck using a small hydraulic mount. Slowly lift the rock, being careful not to let it fall off the mount.
