The S906Ml-AK root cutter motor from Southland Tool is built from the same platform as the S906M-1 motor, but has an upgraded process for the internal parts that makes it smooth to turn, improving hydraulic performance, and nearly eliminating internal corrosion. This process know as “advanced kinetics” uses a finish that improves the friction coefficient, allowing parts to run smoother, which reduces drag, saves water, and increases productivity. The metal becomes denser to ward off corrosion and wear. The cutter is designed for lines from 6 to 30 inches. The motor can accommodate hose sizes of 3/4, 1, 1 1/4 and 1 1/2 inches without being bushed down or up. It can handle flows from 40 to 170 gpm and pressures from 1,500 to 3,000 psi. It is rated up to maximum 288 pounds of torque and 220 pounds of continuous torque, which is ideal for cutting taps in larger sizes. 714-632-8198; www.southlandtool.com.
