  • Exceptional productivity: 23 hours runtime at 50% load
  • Durable: 1500rpm low-speed Kubota engine
  • Reliable: AVR alternator protecting all your sensitive appliances from voltage variation.

  • Easy maintenance: Side doors can be wide open to give access to the filters and be able to check the coolant and oil level easily. Mounting and demounting the fuel tank has been made simple by making the bottom floor entirely flat. The radiator can be cleaned by removing both side front covers.
