Case 460 Trencher – Specs, Parts & Maintenance Guide

The Case 460 Trencher is a robust, mid-size ride-on trencher designed for tough jobs in utility installation, irrigation, and light pipeline work. It builds on the legacy of the earlier Case 360 with a stronger frame, improved hydraulics, and enhanced operator comfort.

Manufactured during the late 1990s into the early 2000s, the 460 offers increased horsepower, deeper trenching capabilities, and the flexibility to mount additional attachments like backhoes or vibratory plows. It’s an ideal machine for contractors who need more power and digging depth without jumping to a large-frame trencher.
