Features
Work Confidently via Standard Cameras and Lighting

The integrated right rear and left camera system, along with powerful LED surround lighting, enhances the operator's 270-degree visibility around the machine, even in low light conditions, all displayed on the main monitor. Additionally, LED front work lights and rear camera remain standard equipment.
Exceptional Performance in Tight Spaces

The excavator excels with enhanced digging forces due to the optional power boost, allowing it to manage tough materials effectively. Its reduced tailswing configuration provides a smooth, well-balanced operation, minimizing the risk of damage in confined spaces.
Simple Emissions System and Built‑In Versatility

The 135 P‑Tier meets Final Tier 4 / Stage IV emissions standards without a diesel particulate filter (DPF), eliminating regenerations and ash‑service intervals to simplify ownership and reduce maintenance. Standard auxiliary hydraulics with proportional control enable the use of a wide range of attachments, increasing versatility and allowing crews to tackle multiple tasks with a single machine.
