Operator's Cabin

The Z45 GEN:2 is available in canopy or cab configurations, allowing you to tailor the machine to meet your specific work environment.

  • Large cab offers state-of-the-art controls, digital display and excellent visibility.
  • Walk-through canopy for easy entry and exit.
  • Optional cab enclosure with heat or heat/air-conditioning system provides protection in extreme weather conditions.
  • Adjustable suspension seat and armrests provide personalized comfort.
  • Excellent visibility in all directions allows safe and efficient operation. Rear mirror provides a view of the back and side of the machine for additional safety.
  • Work lights and integrated boom light enhances the operator’s view after dark.


The controls on the Z45 GEN:2 compact excavator are ergonomically designed and easy to use.

  • Digital Operator Interface shows real time system information, service reminders, and 90 days of operating history.
  • Large travelling pedals are easy to press and allow confident, reliable work.
  • Pilot operated joystick controls are operated by simple wrist movements, reducing fatigue during a long workday.
  • One-way auxiliary functions can be controlled by a foot pedal or joystick buttons, allowing optimal control of high-flow attachments such as compactors or breakers.
  • The operator can easily select from ISO or standard operating control patterns with the flip of a mechanical lever.


Rugged, high-strength boom incorporates features to protect and extend the life of moving parts and components.

  • Precision welded boom is constructed with thick side plates that are reinforced by contoured transition plates.
  • Heavy-duty sliding cylinder guards protect exposed cylinder rods from damage.
  • Integrated boom light illuminates the work area and allows for safe and effective operation after dark.
  • Reliable single pin boom mount design for optimal durability and component life.


The undercarriage of the Z45 GEN:2 compact excavator was designed with serviceability and longevity in mind.

  • Staggered tread and mandrel design combined with shorter track pitch reduces vibration.
  • Long tracks provide a smoother ride over rough terrain.
  • Tracks are short-pitched to reduce wear, fatigue and damage.
  • Angled crawler frame reduces soil buildup on the undercarriage, extending the life of rollers and tracks.


The Z45 GEN:2 compact excavator is built around a powerful, reliable emission-certified Tier IV Yanmar diesel engine.

  • Yanmar Tier IV certified diesel engine with 37.7 hp provides excellent balance in power and fuel conservation.
  • ECO Mode can be activated from the cab with a switch. When activated, the engine speed is reduced by 10%, reducing fuel consumption for lowered operating costs.
  • Auto Deceleration lowers noise and emissions levels when the hydraulic movement has not occurred for more than four seconds. This increases fuel economy and lowers operating costs.
  • Proven technology provides reliable operation and a fuel efficient system.
  • Easy-starting, even in cold weather without the need for block heaters or starting fluid.

The advanced hydraulic system on the Z45 GEN:2 provides long-lasting, efficient power precisely when you need it.

  • Standard auxiliary proportional hydraulics give the operator infinitely variable control of the hydraulic flow.
  • Hydraulic system is designed to enhance engine performance, resulting in a more efficient system.
  • Two variable pumps and two gear pumps combine oil and redirect the flow to where it is needed, allowing for simultaneous operation without loss of power.
  • Smooth operation, even while using the boom and arm during turning.
  • Auxiliary hydraulic valve, tubing and hoses with flat faced coupler connections are standard equipment.
  • Two-way and one-way auxiliary flow valve with direct-to-tank bypass valve feature is standard equipment.

  • Two large, rear doors open easily to expose the battery, engine oil, air filter and cooling system.
  • The right-hand side cover is easily removed with just two bolts. Remove the top right hand side to easily clean behind the radiator.
  • A cover on top of the unit on the right side allows access to the fuel supply and a handy tool storage tray.
  • The access panel beneath the operator’s seat easily opens to reveal the starter motor, fuse panel, alternator and fan belt.
