Use this comparison to choose between the Catawba Middlebuster Potato Plow, the Sub Soiler, and the Speeco Heavy Duty Post Hole Digger. These 3 point tools all work in the ground, but they solve different jobs: the middlebuster opens rows and shallow trenches, the sub soiler breaks deep compaction and improves drainage, and the post hole digger makes consistent holes for posts, planting, and farm projects.
