What the specifications mean
The standard shipping length excludes the longer push-pull arrangement. Confirm the fitted rear and pushing equipment before planning trailer space.
Cutting width and bowl capacity describe different parts of the loading task. Select the machine around material, loading method and haul conditions, not bowl volume alone.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used 621 inspection priorities
- Inspect bowl floor, cutting edges, apron, ejector and associated cylinders for wear, leakage and repair history.
- Check hitch and steering joints, tires and drivetrain service records.
- Identify the installed push-pull or other equipment and inspect its mounts and operation before treating it as included working equipment.
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
- Budget bowl and cutting-system wear separately from tires and powertrain work.
- Build utilization from loading, haul, discharge and return time, with the actual loading assistance and site constraints included.
Configuration
Equipment and configuration
Match the installed equipment to the serial-specific build record and the measurement basis shown above.
Configuration details to confirm
- Single or tandem engine
- Push-pull arrangement
- Coal or earth bowl
- Towing tractor
A model specification does not establish compatibility with a particular attachment or option.
