A floating cut-off bar coupled to a feed drawer whereby a mechanism allows the floating cut-off bar to engage the specified contour of side rails and a division plate in a mold box assembly and aid in material distribution by screeding excess material and delivering additional material to areas of the mold box as necessary and method of making wall blocks therefrom. The specified contour of the side rails and optionally division plate is designed to optimally deliver material to achieve a specified uniform density of the block produced for greater structural integrity, strength and durability of the block.
