WC IL | Run mole knife 7" deep and pull 12 row bar with Magnum 305. 20ish, maybe 22 hp/row. Depends on conditions. The mole knife would run well at whatever depth we wanted to run at. We just prefer that 7" range or so. The important part of the mole knife is to make sure it runs at the proper angle. If a mole knife is moving around (side to side, back and forth, up and down, etc) it will pull harder and not do as good of job as if it runs at the angle it was designed to run at. | |
