  • Quick and easy service access from the forward tilting cab and the arrangement of internal components makes it easy to maintain the machine.
  • Class leading track-on-ground of 57.2” decreases ground pressure while increasing digging performance.
  • Optional high flow hydraulics increase the range of usable attachments improving efficiency and productivity.

Ergonomic Cab Design

  • A wide door and step as well as ergonomically located handles make entry and exit easy regardless of the size of the operator

  • Large, illuminated switches give quick accessibility to controls regardless of the time of day or whether the operator is wearing gloves.
