What each meter measures

Engine hours — total run time (idle + working). Most-cited number.
Working hours — hydraulic load applied (excludes idle). Best indicator of pump/cylinder wear.
Travel hours — track motor operation. Indicates undercarriage wear.
Idle hours — engine running, no hydraulic load. Tells you about fuel waste.

Healthy ratios

A well-managed machine typically has working hours = 70-85% of engine hours. Below 60% indicates excessive idling — operator training opportunity. Travel hours typically = 8-15% of engine hours; higher suggests heavy site-to-site movement.
