What the specifications mean
The published GD655-7 values remain attached to their stated configuration and rating basis.
The official brochure separates 17,350 kg base weight from 19,480 kg with ripper.
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 GD655-7 inspection priorities
- Measure circle, drawbar, saddle and moldboard wear through the full range of motion.
- Inspect tandem cases, articulation, wheel lean, steering and tire condition.
- Verify AWD and grade-control functions only when physically installed and operational.
- Inspect electronic proportional controls, tandem housings and ripper mounting when fitted.
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
- Circle and drawbar wear can materially change repair exposure and grading accuracy.
- Tires, tandem drive, front axle and hydraulic functions need separate reserves.
- Technology packages require hardware, calibration, subscriptions and support checks.
Compatibility graph
Attachment considerations
Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.
Rear rippers and winches
Verify rear mounting, hydraulics, tool weight, manufacturer application.
Open attachment researchDozer blades and application implements
Verify blade linkage, machine class, hydraulics, guarding.
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.
Use the equipment transport dimensions worksheet to record this GD655-7's actual travel configuration, measured length, width and height, weight evidence and any detached components. Send the completed record to the carrier with the loading details.
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
