• Operator controls are color coded and designed for easy identification and operation.

The ROPS and seat belt work in conjunction to provide a protective zone around the operator:

• It reduces the operator’s risk of being crushed under the vehicle should it overturn.
• In most situations, the ROPS limits the overturn to little more than 90 degrees.
• When used with a seatbelt, the ROPS is very effective in preventing deaths and serious injuries.
  • Use of the seat belt is recommended when operating with ROPS in the upright position.

Foldable ROPS and retractable seat belt are standard equipment:

• Position adjustment pins provide a good grip and make changing the angle of the ROPS easier.
• Easy-fold ROPS includes a built-in isolator.
• The ROPS can be pinned halfway down to accommodate machines equipped with a material collection system.
• Door height of most garages will accommodate the machine with ROPS in the fully raised position.
  • Easy-fold ROPS improves the ability to store the ZTrak in structures with a lower door opening.
