1. A method to produce blocks, the method comprising:
positioning a production pallet beneath a mold box to enclose a bottom of a mold cavity; wherein the mold box includes opposed side walls and opposed front and rear walls which together form a perimeter of the mold cavity shaped to form a block, the mold cavity having an open top and an open bottom;
depositing block forming material into the mold cavity; and compressing the block forming material within the mold cavity to form a block by lowering a stripper shoe to enclose the open top of the mold cavity, wherein, in an installed orientation, the block includes an outward-facing front face that is adjacent to a top irregular surface and to first and second irregular side surfaces, the stripper shoe having an irregular molding surface shaped for forming the top irregular surface of the block and contoured molding surfaces shaped for forming a first portion of the outward-facing front face and a first portion of the first and second irregular side surfaces of the block, wherein a transition between the first portion of the outward-facing front face and the first portion of the first and second irregular side surfaces of the block formed by the stripper shoe and the remaining portions of the outward facing front face is irregular and nonlinear; and
removing the block forming material from the at least one mold cavity after moving the front wall to the retracted position.
