What the specifications mean

01

The published D85PX-18 values remain attached to their stated configuration and rating basis.

02

Standard straight-tilt blade, long drawbar, 910 mm single-grouser shoes, ROPS cab, no rear ripper; standard PX undercarriage.

03

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 D85PX-18 inspection priorities

  • Obtain measured undercarriage percentages and matched-component history.
  • Inspect blade linkage, push arms or C-frame, equalizer bar and pivot points.
  • Test steering, transmission and installed grade-control hardware under load.
  • Match the D85PX-18 model plate, fitted equipment and serial/PIN to the cited generation and 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

  • Undercarriage life depends on material, slope, travel and turning practices.
  • Blade edges, rear equipment, final drives and cooling need separate reserves.
  • Technology value depends on installed, licensed and calibrated hardware.

Compatibility graph

Attachment considerations

Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.

Implements are treated as configurations for this machine class. Blade, ripper, winch and rear-equipment details must be verified on the actual dozer.

Before 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
