Abstract: A trim saw is mounted in conjunction with a hogger, or device for reducing scrap to particles, or saw dust. The hogger is made up of a any desired number of units that will reduce scrap to sawdust. Each unit has a pair of oscillator plates that hold a pair of semicircular blade portions at an angle to the axis of rotation, so the blade portions sweep a wide kerf. Since the blades are generally conventional saw blades, they can be sharpened by conventional machines, obviating the need for hand sharpening. Also, the relatively fine teeth on the hogger blades allows substantially uniform power loading for uniform operation.
