These two generators round out an already robust line of compact power generators to which the rental community has responded very favorably.”

Flexibility in System Application

Kohler Power Systems offers mobile generators for any application from industrial power to public events. Ideal for the rental world, Kohler’s 145REOZT4 and 175REOZT4 are EPA-emission certified for non-road use and come equipped with a rugged DOT-certified trailer and durable enclosure. Both units utilize John Deere Tier 4 Final 6.8L engines that help lower operating costs with efficient performance and fuel savings.

Feature Rich

Both the 145REOZT4 and 175REOZT4 generators offer a number of features to deliver straightforward operation and dependable performance in the field. These features include:


  • • A heavy-duty air cleaner with restriction indicator
  • • Fuel tanks sized for 24-hour runtime
  • • External emergency stop
  • • Stainless steel door latches and hinges
  • • 110 percent environmental containment for fuel, oil and coolant
  • • Two-way fuel valve to easily switch from onboard to external fuel source
  • • Three position selector switch
