Ease of use
The commands are easy to use and the intuitive new generation LCD monitor provides machine information in a clear and easy-to-read format.
Arm Direction Translation Mode
It is even easier to move around the construction site thanks to the Cat arm steering option. Easily switch from traditional translation commands with levers and pedals to joystick controls to move the machine and operate the blade. Less effort and better control are within reach!
Exceptional Performances in a Compact Format
Powerful lifting and digging performances allow you to complete the work more quickly. The compact design of the radius allows you to access tight spaces and work in them. The free position of the push blade makes it easier to clean. An optional swivel blade is also available for smoother leveling and simpler backfilling applications.
