What the specifications mean

The published 140M3 values remain attached to their stated configuration and rating basis.

M Series 3, non-AWD, Tier 4 Final / EU Stage IV; standard 14.0R24 tires on multi-piece rims, full fluids and operator, no front push block or rear ripper; moldboard rotated within tire envelope for transport. Net power at 2,000 rpm (ISO 9249 / SAE J1349).

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 140M3 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.
Match the 140M3 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

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.
