Advantages and Features


  • Impeller Clutch Torque Converter (ICTC) reduces wheel slippage and tip wear by modulating rim pull from 100 to 20 percent while depressing left pedal. After 20 percent rim pull is achieved the left pedal applies the brake.
  • Reduces wheel slippage without reducing hydraulic efficiency.
