What the specifications mean
The published 304 values remain attached to their stated configuration and rating basis.
Caterpillar 304 — Dimensions - Standard Stick. *Overall Shipping Length depends on blade position during shipment.
An individual machine must be verified by serial/PIN, installed equipment and actual measurements.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used 304 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 304 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.

Attachment considerations
Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.
Compact excavator buckets and couplers
Verify pin or coupler geometry, tool weight, machine configuration.
Open attachment researchBreakers, augers and compactors
Verify flow, pressure, return, case drain, controls.
Open attachment researchBefore confirming fitment
- generation and machine configuration
- mounting interface, coupler or pin geometry
- hydraulic flow, pressure, return and case drain
- attachment weight and machine capacity limits
- electrical controls or required machine options
Model-reference transport profile
Transport reference
Reference measurements retain their configuration and verification status. Confirm the actual transport setup before booking.
Reference specifications can differ from the actual configured machine. Confirm dimensions and weight before booking transportation.
Confirm or replace before a transport request
- actual weight
- actual travel length, width and height
- attachments and removable work tools
- bucket, blade, carriage or boom position
- loading condition
