What the specifications mean

The manufacturer labels the standard-lift dimensions approximate and bucket/tire dependent. Confirm the actual widest part and stowed tool projection.

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

Used 903 inspection priorities

Inspect articulation, tires, compact linkage and attachment locks; verify the installed bucket and lift package.
Record the exact serial/PIN, installed options and inspection limitations. These are purchase inspection priorities, not claims of a model-specific failure pattern.

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

Compare turning needs, tool compatibility and transport with a skid steer performing the same task, including site-surface effects.
Use the ownership calculator with quoted repairs, actual scheduled hours, utilization and transport costs; leave unknown assumptions visible.
