How to Convert a Baler to a Log Splitter

Log splitters are garden machines that split short, full-circumference logs into multiple pieces for easy burning. Farmers and homeowners have always searched for improved ways to harness the power of on-hand equipment to split logs. One of the more creative DIY log splitter applications involves the conversion of a hay baler into a log splitter. Hay balers are traditional pieces of farm equipment that compact hay or straw into a bale. Most balers rely on lateral compression of the hay with a reciprocating piston. It is this motion that can be converted into the mechanical thrust action needed to split logs.

      Analyze the platform under the reciprocating arm of the baler. While models vary, most have some sort of platform or horizontal surface below the arm. If the subject baler does not have a platform extension under its reciprocating arm, build one from an 8-foot piece of 1/2-by 4-by-8-inch steel I-beam.

      Drill two 3/4-inch holes in the center flange on one end of the beam. Bolt on 3/4-inch extension rods or fabricated 1/2-inch steel bars that can be drilled and bolted to the axle of the baler. If necessary, cut and weld a 2-foot piece of I-beam or angle iron under the I-beam arm to bring it off the ground to a working height.

      Construct the push plate from 1/2-inch steel plate. This is the plate that the horizontal arm pushes against the wood. Cut or burn two 8-by-8-inch pieces of steel and weld them together to form a simple right angle. Cut a smaller, 4-by-5-inch piece of the same steel and drill it to a size that fits the horizontal arm's PTO connection. -- these are typically an eye-bolt through which attachments are bolted.

      Weld the small piece to both flanges of the big angle with the small piece standing edgewise, not flat. Drill and bolt this assembly to the baler's reciprocating arm. Bolting it preserves the arm's function and integrity. The back side of the big angle will be the push plate, facing the work.

      Measure and cut a 6-by-8-inch piece of 1-inch steel plate. The plate must be cut with an acetylene torch. Heat one of the long edges of the piece and use a heavy file to shape it into a knife-like edge. This is the piece of steel that forms the splitting edge that is driven into the wood. Weld it to the horizontal surface at a point which brings the cutting edge 4 inches beyond the farthest reach of the push plate.

      When the reciprocating arm reaches its full extension the baler will reverse its direction and the arm will be retracted back into the baler box. Logs of less than 24 inches are placed on the horizontal surface. When the arm is next extended the push plate drives the log against the splitting edge and splits the log.
