A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.

Used 307.5 inspection priorities

Inspect tracks, sprockets, rollers, idlers, final drives and travel response.
Measure boom, arm, bucket, swing-post and blade pin wear.
Operate the coupler and auxiliary circuits with the intended tool when practical.
Match the 307.5 model plate, fitted attachment and undercarriage to the cited reference configuration.

Configuration-aware inspection: these checks are triggered by machine category, installed configuration and technology package. Brochure-listed technology must be physically present, active, licensed and calibrated on the used machine.

Hours, condition and ownership cost

Hours are context, not a condition grade. Duty cycle, idle time, maintenance evidence, wear-system measurements, structural repairs and installed technology should be evaluated together.

Cost drivers to model

Track wear, compact service access and attachment duty drive hourly cost.
Blade, coupler and auxiliary packages materially affect fit and value.
Trailer, tow vehicle and attachment mobilization belong in the cost model.
