Features and Benefits

  • Increased performance: efficient gear train combined with electronic controls tailored to the needs of the specific application to optimize machine performance.
  • Safety: the control system looks after the transmission so the operator can focus on the operation of the machine. Speeds and interlocks can be programmed to meet the needs of the specific machine.
  • Ease of operation: available automatic shifting or manual power shift combined with shift inhibits and interlocks simplify the operator’s job and allows for concentration on the job rather than the powertrain.
  • Reduced downtime: Durable heavy-duty components, combined with electronic controls which prevent overspeed, shift shocks and reduce the effects of operator’s error, result in increased machine availability and less wear and tear on other machine components.
