I own both types. My Jacobsen cuts reverse (opposite the wheel direction). It cuts like a fine golf course mower, but will bog down and clog up on high grass. My Ford flail cuts forward (same as wheel direction) without binding up in tall grass. The Ford cut is rougher but can handle tall weeds. Depends on the usage, weekly cutting with reverse or monthly cutting with forward. Neither mower will throw anything. Not recommended for heavy brush and branches, the rotor bearings can shatter or the rotor can get bent. A well balanced rotor has minimal vibration.
