The Log Boss Carriage is made of superior construction that stands up to harsh sawmill environments. Log Boss uses servo-controlled linear positioners for precise knee alignment, and features straight line positive dogging to eliminate potential mis-cuts. Two to five standard knees slide on chromed round and flat-ways. It is an ideal candidate for large diameter logs of 42" to 60" (107 cm to 152 cm) in diameter. Log Boss is an industry-tested product known for being robust and reliable. Coupled with our state of the art 3D optimization systems, Log Boss achieves the industry`s best recovery rate.
