What the specifications mean
This is documented as a drum screen. Interchangeable star-deck capability has not been evidenced for the exact SM 620.3 and is not used to place it in a convertible subtype.
A higher folded transport height than working height is not a unit swap: the manufacturer reports different positions. Use the correct configuration for a building entrance, trailer route or deployed site layout.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used SM 620.3 inspection priorities
- Inspect the drum, screen surfaces, cleaning access, support components and the selected mesh arrangement. Confirm the material and product specification expected from the screen.
- Inspect the rear and side belts, folding joints, supports, coupling and trailer running gear. Confirm whether the rear conveyor is the standard 5,500 mm or shorter optional version.
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 diesel, electric and hybrid drive packages using the actual installed equipment and site supply. The options list does not establish that a used machine includes all drive modes.
- Budget for screen changes, cleaning, belts and feed preparation; optional grids and separation equipment should be priced as part of the complete process.

Match the installed equipment to the serial-specific build record and the measurement basis shown above.
Configuration details to confirm
- Scalping or finishing
- Deck arrangement
- Screen media
- Mobility
A model specification does not establish compatibility with a particular attachment or option.
